This is the brief help for the map at http://maps.ozultimate.com
Layers: The map has two main layers: the NSW Imagery (Aerial Photos) layer and the NSW Topographic Map layer. The map only covers NSW. Use the slider in the top right to transition from one to the other.
Load Files: Drag and drop GPX (from your GPS), KML (Google Earth) or GeoJSON files on to the map and they will automatically appear, or you can use the File Open icon.
Draw: Click on the respective icons to draw Lines, Polygons or Markers. These can subsequently be edited or deleted using the relevant Edit and Delete icons.
Add labels: Click on a feature, and box will pop up to add a label. The label will be visible when you hover over the feature.
Distance Calculation: When you have drawn a Line, the distance will pop up. If you subsequently edit the Line, the distance will recalculate. Useful for things like measuring the length of bushwalking tracks.
Area Calculation: When you have drawn a Polygon, the area will pop up. If you subsequently edit the Polygon, the area will recalculate. Useful for things like measuring the size of canyon catchments.
Save to Computer: Use the various Save icons to download the features to your computer, in GPX (for GPS), KML (for Google Earth/Maps) or GeoJSON format
Share Link: Click on the Link icon to save the data you have loaded/drawn to the server, and create a link that you can copy and share with others
