I need to measure distances between buildings and such for surveying purposes.
I need a range of about 650 feet.
I need to be accurate to +/- 10 feet.
Are there any laptop based GPS units capable of being that accurate?
My budget is around $150
Are these for existing buildings? what are you trying to accomplish.

You could use this site to measure between buildings. Zoom into were you want to measure. Turn on the ortho photos and you can use the measuring tool.
To measure buildings there is pictometry.com and then a downloadable survey program which is spot on to measuring building widths.
Its not really for between buildings. Im working on a municipal road construction project with blaster. I need to find what buildings fall within the blast radius and may be damaged. The effective blast radius is 600 feet.
I was hoping to go out in the field and mark 2 GPS coordinates and find the distance until I hit about 600.
I hate the dickless wheel that they use to measure distances now… it doesnt work over wooded and rough terrain which this site includes… plus its gay.

You can get 100% accurate cad maps from city hall…
Yes Very accurate GPS systems are available, USB external antennas w/ software.
