Map Guides, Travel Tips & Reviews
Understanding Notices to Mariners
A chart is only as good as the information it contains. Notices to Mariners are one of the key ways that charting authorities communicate important updates affecting navigation safety. This guide explains what Notices to Mariners are, why they matter, and how they relate to the charts and navigation tools available through Mapworld.
What Is GDA2020?
Whether you are using a NSW Topographic Map, a Queensland QTopo map, or one of the new AUSTopo 1:250,000 maps, understanding GDA2020 helps explain how modern Australian mapping works — and why newer maps are better aligned with today’s satellite positioning systems.
How to Take a Bearing
Learning how to take a bearing is one of the most important outdoor navigation skills you can develop. Whether you are bushwalking, hiking, orienteering, leading a school group, working in the field, or travelling through remote country, a compass bearing allows you to move with purpose rather than simply hoping the track continues in the right direction.
