As you can see, acquiring a topographic map is essential for any permaculture property design work! However, the problem is that getting a topographic map that explicitly shows your property features with a satisfactory contour overlay can get rather expensive pretty soon. For a detailed and accurate topographic map, with contours every 2 ft/0 ...

This article describes how to create and print customized Canadian Topographic (topo) maps using free digital topographic map information made available on the Internet by the Government of Canada (NRCan) and the free Quantum GIS (QGIS) computer application. QGIS can also be used to create maps from other free or commercial digital map information such as Open Street Map or US nautical charts ...
Topographic Maps are a 2D way to show elevation and shape on a map. As long as you know how to read them, you should be able to visualize what that area looks like on the actual Earth. But this isn't always easy! 3D models are an easier way to see what the Earth looks like - this is an easy set of instructions to make your own 3D model of an ...
