Permaculture Design/Base Map and sector analysis

A base map is a drawing that captures everything that is in place already on a property or space. It includes buildings, fences, trees, hedges, pathways and driveways, power lines and pipes... things that are in place. A sector analysis map is a drawing that depicts what is happening in that base. What is the sun's path, what are the wind and rain directions, where are the main areas of people activity, where are the shade areas.
