  1. Getting GPS Data into GeoMedia 5.2 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.

  2. Bringing your GPS Data Into GeoMedia Professional 5.1 Since your GPS data is exported in the ArcView format, you must prepare the data for use in GeoMedia. 1. First go to Start, then “All Programs”, GeoMedia Professional, Utilities and finally “Define Warehouse Configuration File”.

  3. 3. Click “Browse” under “ArcView workplace folder”. 2. Select ArcView for your data viewer. 5. Click the Coordinate System File button. Then the next button. 4. Navigate to your export folder which houses your GPS data.

  4. 7. Click the Geographic Space tab and make sure that the Geodetic datum is WGS84. 6. When the above window appears, be sure Geographic is the selected coordinate system. 8. Name your .csf file geographic. Click Save. 9. Click next.

  5. 10. Click Finish. You will see a message telling you that an .ini file has been created. Click ok and then close out the “Define Warehouse Configuration File”. 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.

  6. 12. Select ArcView as your connection type. Click “Next”. 11. Go to the Warehouse menu, then “New Connection”. 14. Select your exported file. 13. Name your connection and select “Browse” to navigate to the folder where your GPS data is stored.

  7. 15. “Access all of the features in the warehouse,” will automatically be selected for you. Click “Next”. 16. “Let the wizard open the connection as read-only,” will automatically be selected for you. Click “Finish”. 18. Choose your gps data connection and click on each of the feature classes you wish to add. 17. To show your data in the map window, go to the Legend menu and “Add Feature Class”.

  8. Your features should appear in the map window.

  9. 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.

  10. Your data from that you have been working with in this chapter so far is in ArcView and therefore read only. To edit your data you must convert from the ArcView format to GeoMedia. 19. First go to the Warehouse menu and select, “Import From Warehouse”.

  11. 20. Select your gps data warehouse as your Source connections and queries. Select School Features as your target connection. Select the feature classes you want to add. 21. Click “yes” and then “ok”

  12. 23. Click on the Insert Feature Button. Looks like a plus sign with a tail. 22. To add features, find a feature (in this case, a building) on the image that was not captured with the GPS. 25. You may see this window pop up. If so click “OK” and continue. 24. Select your warehouse and feature class in the drop-down menu that appears just above the Insert Feature button.

  13. 27. When you have finished outlining the feature, right click and choose “End Feature. 26. Choose the feature you wish to digitize and trace the outline of the feature. 28. In the properties window, type the function and name of the building. Click OK. 29. You will now be able to see your new feature class outline around the building. 30. You may notice that the outline of the building is difficult to see.

  14. 32. The style definition box will pop up. You can change the style of both the boundary and fill of your feature class. Click on the color box to change colors. 31. You can change the style of the symbol by double-clicking on the symbol in the legend. 34. Click the Area Fill Tab. Select Solid. Then click on the color box to change colors. 33. You may choose the color from this palette.

  15. Your feature class is now customized to your specifications.

  16. At this point we should have mapped: • An athletic field • A flagpole • The 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 campus • Parking lots around campus • Any gyms or assembly locations • Any other buildings that haven’t been mapped • Other 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.
