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. use this site\ [http://gis1.erie.gov/website/Erie\_help/help.htm](http://gis1.erie.gov/website/Erie_help/help.htm) 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](http://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. ---
