Mapworld and the Royal Flying Doctor Service
by Christopher O'Keeffe
June 20, 2026
For more than 30 years, Mapworld has supported the Royal Flying Doctor Service with maps, navigation equipment, practical training and technical assistance—helping teams understand, plan for and travel across some of the most remote country in Australia.
The Royal Flying Doctor Service is one of Australia’s great institutions.
Its aircraft are recognised across the country.
Its doctors, nurses, pilots, engineers, operations teams and support staff work across distances that can be difficult to comprehend from a city office.
A patient may be hundreds of kilometres from the nearest hospital.
A clinic may be reached only by air or after a long journey along regional roads and remote tracks.
A base may be responsible for an operational area larger than many countries.
In this environment, geography is never abstract.
Distance matters.
Terrain matters.
Road access matters.
Airfields matter.
Fuel matters.
Weather matters.
Communications matter.
And reliable mapping matters.
For more than three decades, Mapworld has supported the Royal Flying Doctor Service with a combination of:
-
Hema Navigator GPS units
-
training in the Hema Navigator HN and HX series
-
ongoing technical assistance
-
Hema regional and touring maps
-
Australian topographic maps
-
aeronautical charts and broad-area aviation mapping
-
large wall maps for planning and display
-
laminated maps for reusable operational reference
-
specialist maps for remote and regional Australia
This relationship has never been about one map or one piece of equipment.
It has been about helping people work confidently across the immense geography of regional, rural and remote Australia.
A Shared Understanding of Distance
The Royal Flying Doctor Service was created because distance could be a matter of life and death.
Reverend John Flynn imagined a “mantle of safety” for people living and working beyond the reach of conventional medical services.
Aircraft and radio made that vision possible.
Maps made it understandable.
A map shows the challenge immediately.
It shows the spaces between communities.
It shows the relationship between a remote station, a regional airstrip and a major hospital.
It shows the roads that ground staff may need to follow.
It shows the ranges, rivers, deserts and coastlines that shape every journey.
The RFDS is known for aviation, but its work extends well beyond the aircraft.
The wider service may involve:
For all of these activities, geographic awareness is essential.
That is where Mapworld’s specialist knowledge has been able to help.
More Than 30 Years of Support
Mapworld’s association with the Royal Flying Doctor Service reaches back over 30 years.
During that time, navigation technology has changed dramatically.
Printed maps once carried nearly the entire burden of regional planning.
Then came increasingly accessible GPS receivers.
In-vehicle satellite navigation became practical.
Digital topographic mapping improved.
Hema Navigator units brought road navigation and detailed off-road mapping together in a single device.
Cloud-based systems later changed the way waypoints, tracks and map data could be stored and transferred.
Through these changes, Mapworld continued to provide products, training and support.
The technology evolved.
The underlying questions remained familiar:
-
Where are we?
-
How do we reach the destination?
-
Which road or track provides access?
-
What happens when mobile coverage disappears?
-
Which map should be used for the region?
-
How do we transfer waypoints between devices?
-
How do we keep the mapping current?
-
What backup should be carried?
-
How does the digital device relate to the printed map?
These are practical questions.
In remote Australia, they deserve practical answers.
Hema Navigator Units and Remote-Area Ground Travel
The Hema Navigator became one of Australia’s best-known in-vehicle navigation systems for regional, touring and off-road use.
Unlike a standard city GPS, Hema Navigator units were designed to help users move between two very different environments.
On-Road Navigation
For highways, sealed roads, regional towns, suburbs and established road networks.
Off-Road and Regional Mapping
For unsealed roads, station tracks, remote routes, national parks, outback regions and areas where ordinary street navigation provided insufficient context.
This combination made the Hema Navigator particularly useful for organisations whose work crossed between cities, regional centres and remote communities.
Mapworld supported users through several generations of the Hema Navigator range, including the HN and HX series.

These included models such as:
Each new generation introduced different hardware, software, map formats and operating methods.
That meant users sometimes needed more than a box and an instruction booklet.
They needed training.
HN-Series Training and Support
The HN series became a familiar sight in four-wheel drives, touring vehicles and regional operations.
These units combined street navigation with off-road mapping, often using OziExplorer-based systems for more detailed mapping and track management.
For users working across remote Australia, the training needed to go beyond entering a street address.
It could include:
-
selecting on-road or off-road navigation
-
understanding map scales
-
locating a position
-
reading coordinates
-
entering waypoints
-
saving important locations
-
creating routes
-
recording tracks
-
locating communities and facilities
-
selecting suitable regional mapping
-
managing files and memory cards
-
understanding the relationship between the GPS screen and a paper map
-
troubleshooting common device issues
A waypoint might represent:
-
a remote clinic
-
a community
-
an airstrip
-
an access gate
-
a fuel point
-
a road junction
-
a station
-
a field location
-
a regular meeting point
For people working over large distances, the ability to store and retrieve these locations could simplify repeated journeys and improve operational confidence.
The HN7: A Trusted Remote-Area Navigator
The Hema Navigator HN7 became one of the most widely recognised units in the HN range.
Its seven-inch display made maps easier to read inside a vehicle, while its on-road and off-road modes allowed users to move from highways into more remote country.
For organisations such as the RFDS, the value of a unit like the HN7 was not simply that it displayed a map.
It could bring together:
Offline operation matters in regional Australia.
A navigation system that depends entirely on mobile reception may lose much of its usefulness beyond the network.
A dedicated GPS navigator receives its position from satellites and can retain mapping on the device.
That does not eliminate the need for planning, current road information or printed backup maps.
It does, however, provide an important independent navigation resource.
The Transition from HN to HX
The transition from the HN series to the HX series represented more than a simple hardware upgrade.
The software environment changed.
The way maps, tracks and waypoints were managed changed.
File compatibility changed.
Some information stored in the older HN system could not simply be moved by inserting the same memory card into an HX unit.
HN-series waypoints and tracks commonly used OziExplorer formats.
The HX-1 used newer GPX or KML-based workflows and cloud synchronisation.
This created real questions for users with years of saved operational information:
-
Can our existing waypoints be transferred?
-
Will older tracks work on the new unit?
-
Which file format is required?
-
How do we convert the data?
-
Where are downloaded maps stored?
-
How does synchronisation work?
-
What happens if the unit is used beyond internet coverage?
These were not theoretical concerns.
A user may have built a valuable library of field locations over many years.
Mapworld helped customers understand these transitions and find workable ways to move, convert or rebuild their information.
That kind of technical continuity is an important part of long-term equipment support.
Supporting the HX Series
The Hema HX series introduced a more modern interface and a closer relationship between the navigator, digital map platforms and cloud-based trip data.

For organisations operating in remote Australia, the HX units offered several useful capabilities:
-
on-road turn-by-turn navigation
-
off-road Hema mapping
-
waypoint management
-
route planning
-
track recording
-
points of interest
-
downloadable map areas
-
synchronisation of compatible trip data
-
access to regional and remote-road information
Mapworld’s support helped users understand not just what the buttons did, but how the device could fit into a practical navigation workflow.
Training and advice could include:
-
setting up the unit
-
switching between drive and explore modes
-
downloading mapping before leaving coverage
-
managing waypoints
-
planning a route
-
recording a track
-
understanding points of interest
-
updating software and mapping
-
choosing compatible accessories
-
keeping the unit powered in the vehicle
-
carrying suitable printed backup maps
A navigation system is most valuable when the user understands it before the journey begins.
Remote country is not the place to open the manual for the first time.
Hema Navigators Supported Ground Operations—not Aircraft Navigation
It is important to distinguish between two different forms of navigation.
Hema Navigator HN and HX units were designed for road, touring and off-road vehicle navigation.

They were not certified aviation navigation systems.
Their role in supporting RFDS-related work was on the ground:
-
travelling between bases and facilities
-
reaching regional communities
-
accessing remote clinics
-
navigating to airstrips by road
-
supporting field visits
-
planning vehicle routes
-
identifying regional roads and tracks
-
understanding the surrounding landscape
Aircraft navigation has its own approved equipment, procedures, charting requirements and regulatory standards.
Mapworld’s support for Hema Navigator units complemented that aviation environment by helping with the complex ground geography surrounding remote operations.
The distinction matters.
A road navigator, topographic map, wall map and aeronautical chart each serve different purposes.
Used correctly, they contribute to a much stronger overall understanding of the operating area.
Training: Turning Equipment into Capability
A GPS device is only useful when the operator knows how to use it.
This is why training has been such an important part of Mapworld’s work.
Effective training turns a navigation unit from an unfamiliar screen into a practical field tool.
A good training session should leave the user able to:
-
locate their current position
-
search for a destination
-
understand the selected map
-
enter and save coordinates
-
identify the correct coordinate format
-
create and manage waypoints
-
follow an appropriate route
-
distinguish between mapped roads and unverified access
-
record a track
-
return to a saved location
-
understand when the device may be wrong
-
use a printed map as a backup
-
recognise when local advice is more current than the mapping
That last point is especially important.
A GPS can show a road.
It cannot guarantee that the road is open.
It cannot know that a river crossing has become unsafe.
It cannot replace permission to enter private or restricted land.
It cannot replace community advice, operational procedures or current aviation and road information.
Good navigation training teaches both capability and limitation.
Why Hema Regional Maps Matter
Hema’s strength has always been regional and touring mapping.
Its maps are built around how people actually move across Australia.
They show more than major highways.
Depending on the map, they may include:
For RFDS teams and support personnel, Hema regional maps can provide an immediate overview of a working area.
Relevant maps may include regions such as:
A state map gives broad context.
A regional map brings the working area closer.
Printed Hema Maps as Essential Backups
Digital navigation is powerful.
Printed maps remain essential.
A printed Hema map does not need:
-
a charged battery
-
a working cable
-
mobile coverage
-
an operating system update
-
a functioning touchscreen
-
cloud access
-
a login
-
a satellite lock before it can be read
It can be opened across a desk or vehicle bonnet.
Several people can look at it together.
It can show a much wider area than the GPS screen.
It can be marked with notes.
It can remain visible during a planning discussion.
This makes printed regional maps useful for:
The best remote navigation system is rarely one device.
It is a combination of digital and printed resources.
Topographic Mapping for Terrain and Regional Detail
Hema maps are excellent for roads, tracks and touring context.
Topographic maps provide a different level of geographic information.
They show the shape of the land.
Depending on scale, topographic maps may include:
For remote-area operations, terrain can influence:
Mapworld supplies topographic mapping across Australia in scales ranging from highly detailed local sheets to broad regional maps.
These include:
-
1:25,000 maps
-
1:50,000 maps
-
1:100,000 maps
-
1:250,000 maps
-
1:1,000,000 maps
Each scale answers a different question.
Choosing the Right Topographic Scale
1:25,000
Best for detailed local terrain, walking access, facilities, local roads and close fieldwork.
At this scale, one centimetre represents 250 metres.
1:50,000
Best for detailed regional work where terrain remains important but a wider area must be shown.
One centimetre represents 500 metres.
1:100,000
Best for broader field planning, regional road context and land-management work.
One centimetre represents one kilometre.
1:250,000
Best for understanding large regions, transport corridors, towns and broad terrain.
One centimetre represents 2.5 kilometres.
1:1,000,000
Best for very broad operational context across enormous areas.
One centimetre represents ten kilometres.
No single scale is best for every purpose.
A large regional operation may require several scales used together.
Paper, Laminated and Waterproof Topographic Maps
Mapworld can supply many topographic maps in different finishes.
Paper
Best for:
Laminated
Best for:
Waterproof Tyvek
Best for:
-
field vehicles
-
remote travel
-
outdoor work
-
wet or dusty conditions
-
repeated folding
-
emergency map kits
A laminated map works well on a wall or table.
A waterproof map works well in a vehicle or field bag.
Paper is often the most economical way to build a larger regional set.
Aeronautical Charts and Aviation Context
The RFDS is first and foremost an aeromedical service.
Aircraft connect remote patients and communities with medical care that might otherwise be many hours or even days away.
Aeronautical mapping therefore forms an important part of the broader geographic picture.
Depending on the purpose and current publication status, aeronautical charts may show information such as:
Current operational flight planning must always use approved, current aviation information and comply with the relevant regulatory and organisational procedures.
Historical or general-reference aviation charts must never be substituted for current operational publications.
Mapworld has supplied aeronautical and broad-area aviation maps for appropriate planning, training, reference and display applications.
These can help provide context for:
-
the distribution of airfields
-
the enormous operational distances involved
-
terrain across a flight region
-
the relationship between aviation and ground transport
-
training and historical study
-
office and planning-room display
Operational Navigation Charts
Operational Navigation Charts, commonly known as ONC charts, were designed at a scale of 1:1,000,000 to combine broad topographic and aviation-related information.
They can show:
Their scale makes them visually useful for understanding very large parts of Australia.
Today, many ONC editions are best treated as historical, educational, planning or decorative references rather than current operational flight charts.
They remain valuable because they show the scale of the continent in a way few other map series can.
For an RFDS office, training area or heritage display, they can help communicate the geography across which the service operates.
Large Wall Maps for Strategic Planning
A large wall map does something a small GPS screen cannot.
It allows a whole team to see the same region at once.
This makes wall maps particularly useful for:
-
strategic planning
-
management briefings
-
service-area discussions
-
regional orientation
-
base planning
-
training rooms
-
operations centres
-
community-service planning
-
identifying gaps in coverage
-
showing the relationship between bases, communities and hospitals
-
displaying transport corridors
-
explaining the scale of an operational region
A wall map can be marked with:
In laminated form, these markings can be changed as planning develops.
Australia Wall Maps for National Context
An Australia wall map is particularly effective when an organisation works across multiple states and territories.
It helps show:
-
the national RFDS footprint
-
the relationship between regional bases
-
major cities and referral hospitals
-
state and territory borders
-
remote population centres
-
transport corridors
-
large geographic gaps
-
national program coverage
Mapworld’s wall-map collection includes Australia maps in a wide variety of styles and sizes, from approximately one metre across to major two-metre planning maps.
Available options include:
The best map depends on the purpose.
A boardroom may benefit from an elegant National Geographic map.
An operations room may need a highly legible laminated Hema map.
A training room may need several state and regional maps displayed together.
State and Regional Wall Maps
The RFDS operates across vastly different landscapes.
A single national map cannot show every operational detail.
State and regional maps can provide a clearer picture of areas such as:
These maps help new staff understand the region in which they will work.
They also help administrative and management teams discuss services without losing geographic context.
A regional map makes remote place names real.
It shows how far communities sit from one another.
It shows which roads connect them.
It shows why an aircraft may be the only practical way to deliver urgent medical care.
Maps for Training Rooms
RFDS work requires continuous learning.
Clinical teams train.
Pilots train.
Operations staff train.
Drivers and support teams train.
New employees need regional orientation.
Maps are valuable in this environment because they turn abstract procedures into place-based discussions.
A training-room map can support scenarios such as:
-
reaching a remote community
-
coordinating ground transport with an aircraft
-
identifying alternative access routes
-
understanding nearby regional centres
-
discussing weather-affected roads
-
locating hospitals and airstrips
-
considering large-scale service coverage
-
planning remote clinic visits
-
understanding map grids and coordinates
Laminated maps allow scenarios to be drawn, changed and repeated.
They become reusable teaching surfaces.
Maps for Community and Clinic Planning
The Royal Flying Doctor Service is not only an emergency retrieval service.
Its work includes regular healthcare for rural and remote communities.
Planning these services requires an understanding of:
A map can help teams see how several communities relate to a single journey or clinic schedule.
It can reveal that locations close together on a list may be separated by difficult terrain or indirect roads.
It can also help show why combining air and ground transport may be necessary.
Geography shapes healthcare delivery.
The map helps make that relationship visible.
Reliable Navigation Requires Redundancy
Remote operations should never depend on one source of navigation.
A robust system may combine:
-
approved aviation navigation equipment
-
current operational aeronautical information
-
Hema Navigator or another ground GPS
-
printed Hema regional maps
-
topographic maps
-
large wall maps
-
current road-condition reports
-
local community knowledge
-
reliable communications
-
organisational procedures
Each component serves a different role.
The GPS provides a live position.
The regional map shows the wider road network.
The topographic map explains terrain.
The wall map supports team planning.
The aviation system supports the flight.
Local advice provides current on-the-ground reality.
Redundancy is not unnecessary duplication.
In remote Australia, it is sensible preparation.
The Importance of Technical Support
Navigation equipment rarely fails at a convenient moment.
A unit may stop charging.
A mount may break.
A software update may change a setting.
A map may disappear after a reset.
A waypoint file may not import.
A user may need to move information from an old HN unit to a newer HX system.
These are the moments when specialist support matters.
Mapworld’s long experience with Hema Navigator products allowed us to help with questions including:
-
device setup
-
charging and power
-
memory cards
-
software updates
-
map downloads
-
waypoint formats
-
track files
-
HN-to-HX migration
-
compatible accessories
-
off-road map selection
-
printed-map backup
-
user training
Sometimes the solution was simple.
Sometimes it required file conversion, software support or referral to Hema’s technical team.
The important thing was understanding the question in practical mapping terms.
Support Beyond the Point of Sale
Mapworld has never viewed specialist navigation equipment as a simple retail transaction.
A professional customer needs more than a receipt.
They may need:
-
advice before purchase
-
help choosing the correct model
-
staff training
-
device setup
-
assistance with updates
-
replacement accessories
-
explanation of map formats
-
printed-map recommendations
-
help identifying topographic sheets
-
guidance during a technology transition
For organisations working in remote Australia, continuity matters.
The person who understands the equipment today may move to another role tomorrow.
New staff need training.
Old data needs preserving.
Maps need updating.
Accessories need replacing.
Support needs to continue after the original purchase.
That has been an important part of Mapworld’s relationship with RFDS users over the years.
Hema Maps and Topographic Maps Work Together
Hema and topographic maps answer different questions.
Hema Maps Answer:
-
Which roads and tracks connect the region?
-
Where are fuel stops and roadhouses?
-
What are the main touring routes?
-
Which towns and communities lie along the journey?
-
What services are shown?
-
How does the region fit together for vehicle travel?
Topographic Maps Answer:
-
What does the terrain look like?
-
Where are the ridges and valleys?
-
Which rivers and creeks cross the area?
-
What is the elevation?
-
What smaller roads, tracks and features are mapped?
-
How does the landscape shape access?
Most serious regional users benefit from both.
The Hema map helps plan the journey.
The topographic map helps understand the land.
The Human Value of Geographic Confidence
Maps and navigation equipment can sound technical.
But their real value is human.
A staff member travelling to a remote community should feel prepared.
A new employee should understand the region.
An operations team should be able to discuss locations clearly.
A driver should know how the GPS and paper map work together.
A planner should be able to see the distances involved.
A team should be able to identify an alternative when the usual route is unavailable.
Geographic confidence reduces uncertainty.
It allows people to focus on the reason for the journey: delivering healthcare, moving equipment, supporting a patient or reaching a community.
The map is not the mission.
It helps the mission happen.
A Relationship Built Around Remote Australia
The Royal Flying Doctor Service and Mapworld occupy very different roles.
The RFDS delivers healthcare and aeromedical services.
Mapworld supplies maps, navigation products and geographic expertise.
But both organisations understand something fundamental about Australia:
Distance changes everything.
A service that works in a city may not work the same way in the bush.
A journey that looks short on a small national map may require hours of driving.
A community may be separated from a hospital by hundreds of kilometres.
A road may be seasonal.
Mobile coverage may disappear.
The correct map may need to show not only the destination, but the entire region around it.
This shared understanding of remote geography has shaped more than 30 years of support.

The Royal Flying Doctor Service is one of Australia’s most respected organisations because it brings care across distance.
Mapworld’s part has been much smaller.
But it has been meaningful.
To help the people doing that work understand the roads, regions, terrain and immense spaces through which they travel.
Because in remote Australia, knowing where you are is never just a matter of convenience.
Sometimes, it is part of reaching someone who needs help.
Frequently Asked Questions
Has Mapworld supplied the Royal Flying Doctor Service?
Yes. Mapworld has supported Royal Flying Doctor Service teams and users for more than 30 years with maps, Hema Navigator products, training, technical support and large-format planning resources.
Which Hema Navigator models has Mapworld supported?
Mapworld has supported several generations of Hema Navigator products, including HN-series models such as the HN5, HN6 and HN7, followed by HX-series units including the HX-1 and later developments.
Were Hema Navigator units used for aircraft navigation?
No. Hema Navigator HN and HX units are road and off-road vehicle navigation devices. They are not certified aeronautical navigation equipment. Their role was in supporting ground travel and regional orientation.
Why are Hema Navigators useful in remote Australia?
They combine on-road navigation with off-road and regional mapping that can operate without continuous mobile coverage. They can also store waypoints, routes and recorded tracks.
Can HN-series waypoints be transferred to an HX unit?
Not directly by simply moving the memory card. HN units commonly used OziExplorer formats, while the HX-1 used GPX or KML workflows. Older data may need to be converted before it can be imported into an HX-compatible system.
Why should a printed map be carried with a GPS?
A printed map provides a wide regional overview and remains usable if a device loses power, becomes damaged or develops a software problem. It is also easier for several people to view together.
What is the difference between Hema and topographic maps?
Hema maps focus on roads, tracks, touring routes and services. Topographic maps focus more heavily on terrain, contours, waterways and detailed geographic features.
What topographic map scales does Mapworld supply?
Mapworld supplies Australian topographic maps in scales including 1:25,000, 1:50,000, 1:100,000, 1:250,000 and 1:1,000,000.
Can topographic maps be waterproof?
Yes. Many Mapworld topographic maps can be supplied on waterproof and tear-resistant Tyvek for field and vehicle use.
Why are large wall maps useful for RFDS planning?
They allow several people to see the same operating area at once and can be used to show bases, communities, hospitals, clinics, airstrips, roads and service regions.
Can wall maps be marked?
Laminated maps can be used with suitable whiteboard markers and map dots, allowing operational information to be added and later removed.
Does Mapworld supply aeronautical charts?
Mapworld supplies aeronautical and broad-area aviation mapping for suitable planning, training, reference and display uses. Current flight operations must always use approved, current aviation publications and follow all applicable procedures.
What are ONC charts?
Operational Navigation Charts are broad-area 1:1,000,000 maps originally designed for aviation use. Many current Mapworld ONC products are now best suited to historical, educational, planning or decorative use rather than operational navigation.
Can Mapworld produce custom planning maps?
Yes. Mapworld can assist with custom sizing, enlargements, printing and lamination where suitable, including large maps for boardrooms, operations centres and training rooms.
