I'm interested in doing rough topographic surveys using my tripod-mounted Brunton transit compass for azimuth readings and laser rangefinder (and maybe an optical level), so obviously going to be much less accurate than using a theodolite and EDM but find (and fast) for the level of accuracy I need for say 25cm contour maps of rural properties.
I'm looking for low-end (but not necessarily free) Windows GUI software that doesn't have all the bells and whistles of most of the $1,000+ packages out there that I can manually transcribe my data points into and do some sort of least squares network adjustment or whatever it's called to solve traverse misclosures etc as well as be able to easily work with and offset for some of the hacky ways of taking observations like fixed height range rods (painted rebar jammed into the ground) and working in some consumer GPS (3 metre error) readings and hopefully getting a reasonable terrain model out of it.
Suggestions? Also any appropriate reading pitched at this level of topographic surveying and cartography would be welcome too! Like this http://www.lulu.com/shop/stephen-eastmead/landscape-surveying-using-handheld-gps-receivers/ebook/product-20624990.html
