Learn how to map your land using open source software and freely available data. This material was presented in a workshop at Oregon State University last year, and is now available on CD as a self-paced course.
This course introduces digital mapping tools and techniques (Geographic Information Systems or GIS), and how small landowners and permaculture designers can use these tools with freely available data for site planning. The course provides an excellent introduction to GIS for any small landowner interested in visualizing terrain of the land, planning layout of buildings and gardens, and using GIS maps in Google Earth. You will learn about freely available aerial photos, topographic data, soil maps, and other spatial layers, as well as open source software used in this course.
