HANK I'm curious -- I came across this while looking for actual mapping tools I could use to take -- an aerial photo of 40 acres -- a topo map of the same (Both those are downloaded from the images zoomed in close at www.terraserverusa.com -- so they register correctly; I was able to make the "white" part of the topo map transparent, leaving only the contour lines, and drop that over the aerial photo (done both with GraphicConverter on the Mac and PhotoEdit on Windows, same result). I now need to lay an 11x11 grid on top of this image -- laid out by a surveyor, and I have it as a plotter printout and scans, and can register three of the four corners of that to points on the topo and photo (courtesy of the Coastal and Geodetic Survey). What I want to do after that is attach a sketch map (already done, but being revised year after year as plant cover, fire, and erosion change the site), along with notes and photos to each of those grid squares. Right now, the grid sketches and notes -- all 11x11=121 of them -- are on paper, and the site's steep, remote, and complicated. I've put each of those 121 squares, topo map and sketches done by the botanical survey, into Sony Clie form -- on Memory Sticks, because I can revise those in the Sony Clie using MobiPaint (sketch on top of the image to show changes) then export back to the Mac. I'd like to be able to make new layers out of these, over time. And yes, I know it sounds like ArcInfo GIS, a few thousand dollars, a Windows box, and a staff -- but this on my own in my spare time. It moves a lot slower than a RPG -- it's a 200 year project -- but it's at least as complicated. There are invaders (problem plants, drunks on 4-wheel-drive ATVs trespassing and tearing up the work) and natives (bear, deer, 300 plus species of plants) and major events (two forest fires since 1987, some slow landslides, some amazingly fast erosion) and minor ones (the Monarch butterflies come through, and lay eggs on the milkweed and hatch out and the next generation continues on the migration) and situations (the couple of patches where it's safe to land a hang glider or paraglider if someone needs to) .... So -- given that this has a large manual and takes a lot of work to understand -- would anyone opine whether it might be useful for me? (Version 4.3.2) |
