![]() That’s it! You should now be able to peruse the map from within Google Earth, overlaying your own points and tracks. When you create the Super Overlay, be sure to create a new folder to store all the resulting files as there’ll be lots! Don’t worry! You can create a Super Overlay which basically chops the map up into small parts so that your computer only has to draw a small part at a time (I found that the “Scale” option provides a poor resolution in most cases). You might get a message that your computer hardware won’t support an image so large. Now you can drop that GeoTiff into Google Earth (or use Add -> Image Overlay). I think using the same name as the PDF is a good idea.Įxporting the layer (your imported GeoPDF) as a GeoTiff You can then select GeoTiff from the dropdown menu and enter the name you want to use for the resulting file. You can then right click the layer (the PDF you imported), and choose Export -> Save As… Dropping the GeoPDF into the “Layers” pane within QGIS Dropping the GeoPDF into the “Layers” pane within QGIS Once it is installed drag your GeoPDF into the “Layers” pane (or use the Layer -> Add Layer -> Add Raster Layer…). Grab it from HERE (or this direct standalone link for Windows). If you want to do this, first you need to install QGIS. ![]() This can take a little while and uses quite a bit of your CPU. I couldn’t get Google Earth to open GeoPDFs but using QGIS you can convert it for free into a GeoTiff. You could also load the map into certain applications for navigation (like Avenza though I’ve never used it). You can now print out the topo map, or just the section you want for your trip. Select the “PDF” radio button and then the “Download PDF” button. It is a simple process to click on the map you want. Viewing the different topo maps on the SIX Maps site. Green just means that the printed map is available for sale. If you visit .au/etopo.html you can see the state overlayed with small green and red rectangles. This works great but isn’t that user friendly.īrowsing the internet I also found that the SIX Maps server now allows the public to download GeoPDFs for free. In Google Earth, one alternative to overlaying topo maps using SIX Maps ‘Network Links’ was to use the NSW Topo ruby script to export a kmz. GIS programs like ArcGIS and QGIS always seemed a little clunky, running slowly and having loads more features than I ever seemed to need. Whilst all these resources are great, having more layers and overlaying my own data is important to me. Enabling the Property Boundaries layer on SIX Maps.Enabling the Topo Maps layer on SIX Maps.This NSW Bushwalking Maps page offers some more information and options: /wiki/resources In fact looks great and appears to have improved on the site allowing you to upload kml, gpx or json (the advantage of seems to be that you can send a link with points included in the URL. You can also view the first edition maps, and ozultimate has created a nice interface allowing you to fade between the two. There you can configure one of the base maps to be the current topo maps, as well as overlay important information such as ‘lot boundaries’ which can be useful when exploring areas near private property. Online you can view the NSW topo maps via different interfaces. The ‘network links’ to the SIX Maps servers I had made were still working but these had always been unreliable and cantankerous. Whilst the satellite imagery is nice to use, having a topographic basemap is also indispensable. All the names I saw looked familiar but to took me a while to start linking all the places back together in my head. I dug up my old Google Earth files and loaded them up. Being locked up in hotel quarantine for two weeks gave me a decent amount of time to re-familiarise myself with the local Australian bush using maps.
