Getting GPS Data into GeoMedia 5.0

At this point, you have successfully collected, corrected, and exported your data using Pathfinder Office. The next step is to get your data into

your GIS. GeoMedia has tools created to help you with this process, which we will cover within the next few slides.

14. Click Finish. You will see a message telling you that an .ini file has been created.

We have been throwing some unfamiliar terms at you, like “INI file,” “Coordinate System,” and “Geodetic Datum.” Try not to worry about the meaning of these terms just now. As you advance in your training these terms will be described and should make sense to you later.

Editing Your GPS Data in GeoMedia

You may find that you need to make changes to your attributes, the shape of your features, or that you need to add more features to your map. This lesson should be helpful in guiding you through some of the steps.

You may not have been able to record all of your buildings on campus due to obstructions, poor signal reception or other problems. You can edit your data as described in chapter 2 and even add new features if needed. The remainder of this chapter describes how to add features to your geoworkspace.

At this point we should have mapped:An athletic fieldA flagpoleThe buildings around campus

Now, you need to decide how you will finish your work. You can use either GPS or heads-up digitizing to map. You will need to map:

All the athletic fields on your campusParking lots around campusAny gyms or assembly locationsAny other buildings that haven’t been mappedOther features that are important on your school grounds

We want you to take some time to develop your skills and a final product that you can be proud of. When you are done with this, move onto the next chapter.
