I´m working on a project to map a colleague´s farm, and then ultimately digitizing that information to produce maps and signage.
To start, we´re focusing on a small agroforestry plantation. We want to capture the fenceline (borders which essentially form polygons), irrigation lines and the locations of a different types & species of trees.
Aerial imagery isn´t that great for this area and we need to be more precise than our GPS unit allows, so we´ve begun doing everything old-school: measuring tape, protractor, pencil & paper.
What´s the best way to make sure all of our lines and angles are accurate & true?
Fencelines around the area form a kind of "hour glass" -shaped polygon, so nothing is really parallel nor perpendicular to anything else. Irrigation lines are more or less straight, with some variance following natural curvature, etc.
After we´ve made all the measurements and have everything locked in & drawn to scale, what sort of program is recommended to digitize (and geo-reference) everything?
I have no experience with AutoCAD, but I feel like it´s inevitable at this point.
