  • When you're done entering your name, scroll down and highlight CLOSE, then press ENTER once. This takes you back to the Point screen, now with your name on it.

  • After you have collected 100 points, from the point screen with your name now on the Comment line, press CLOSE ONCE to "close" the unit's data collection at this particular location. The screen will then revert back to the New Feature screen. A "Feature Stored" message will briefly appear at the bottom of the screen, indicating that this feature has been stored in the new file that you created when you started collecting data.

Move to the next car location before you press any more buttons.

You are now at a minor fork in the road; I recommend option #2, but either is OK.

1) From the New Feature screen, you can press CLOSE again, which will take you back to a screen where you will be prompted to close the current rover file. If you wish to back further out, and create a new rover file, press CLOSE again. The unit asks you "Please confirm; Close rover file". If you select Yes, this will close this file. If you want to collect new data, you'll have to "Create new file" again.

2) From the New Feature screen, with Point and Now highlighted, you can press ENTER and the GPS unit will begin to collect points for a new feature (a new car location), but within the existing rover filename.

For this exercise, I suggest you use option 2), and just collect all the feature data in the one rover file. But don’t panic if for some reason you go too far back and close this rover file No harm done, just "Create a new file" at the prompt and simply start over at the next car.

Make sure the group travels to each group member's car (there is safety and camaraderie in numbers), and insist that the car owner be the one that operates the unit. Meanwhile, the rest of the group will coach the hapless individual. When finished with the cars, return to the GIS computer lab, making sure that you collect a GPS point at the entrance to the building on your way in. Label this point as Entrance in the Comment field. Once this is done, turn off the GPS

Back In the Office – Step 3 - Transfer GPS data from GeoExplorer3 to your computer with Pathfinder Office Discussion: First, each group member should create a new folder (name it Exr02) inside their own GIS_I folder. You are now ready to begin downloading the GPS data from the receiver to a computer. Procedure:

If the GPS unit is communicating with the computer, a green connection line and a yellow icon that looks like the Geoexplorer 3 will be visible in the upper RH corner of the computer screen.

  • In PFO, select Utilities > Data Transfer
