Field Work: GPS with Jim Bills Part II

Today Jim Bills, Nazar Albarghsh, and myself drove to Mission, Kansas to do some training and checking of certain manholes. Jim and I went over using the GPS reciever and "popping" manhole lids to check that the number of pipes and direction they travel match what is on the maps. Then Jim and Nazar walked around to check other aspects of the map for accuracy while I "ran" the GPS reciever. Operating the GPS reciever is a relatively simple process. First you set up and level the tripod. Then on the GPS touchscreen you open the Mapping software and watch it acquire satellite signals and the WAAS beacon. Once its ready you select, create new waypoint, JCW sewers, and click start. It will then begin to log as indicated by the top right of the screen (you will see a number counting up from 0) You wait till it gets to 600 (seconds, which is 10 minutes) and then click stop recording and move onto antoher manhole. While the GPS is running on the second manhole return to the first, lift the lid with the hook and compare the number of pipes to those on the map.
