Importing DeLorme GPL Data

RockWorks | Utilities | File | Import | GPL (Delorme GPS)

This program reads GPS "tracks" files output from Delorme software programs and GPS units.  The points can be recorded into the RockWorks Utilities datasheet in longitude and/or UTM coordinates.

Step-by-Step Summary

Menu Options

• Input File: Click here to browse for the GPL file to be imported.  
• Include Date/Time: Insert a check here if the date and time information in the GPL file is to be imported.  Expand this heading to specify:
  • Format String: Click on this item to specify the desired format for the date and time string.  The default is mm/dd/yyyy:hh:mm:ss.
  • GMT Offset (Hours): Click here to enter number of hours to add to or subtract from the recorded time.
• Include Lon/Lat: Insert a check here if the longitude and latitude coordinates are to be imported.
• Include UTMs: Insert a check in this box to convert the longitude and latitude coordinates to UTM and record them in the datasheet.  Expand this heading to define the UTM conversion settings.
  • Projection (Datum): Expand this heading to choose the desired projection.  If you don't know which to choose, the WGS-84 (NAD-83) option is one of the more common choices. 
  • Zone: In order to translate coordinates between longitude/latitude and UTM, you need to define the UTM Zone for the translation.
    • Automatic:  (Default)  RockWorks will read the range of the longitude coordinates being translated and pick the zone that best encompasses them.
    • Manual: If you prefer to select the UTM Zone manually, expand this heading to do so. You should choose a zone with a longitude range that encompasses your longitude coordinates. For example, if you were translating coordinates in the Denver, Colorado, USA area, you would choose UTM Zone 13 which extends from -102 to -108 longitude.  (Western longitudes are noted as negatives.)
  • UTM Units:  Expand this heading to specify if the UTM coordinates should be saved as meters or feet.
  • X-Offset, Y-Offset: Type in the number of UTM units, declared above, to be added to or subtracted from the program-computed coordinates.  These could be used to correct for translation errors, or to reduce the size of the UTM coordinates to represent a more local system. If no offset is desired, you can enter 0.
• Include Elevation: Insert a check in this box to import the point elevations.
• Include Heading: Insert a check here to record the point to point bearings.

Step-by-Step Summary

1. Access the RockWorks Utilities program tab.
2. Select the File | Import | GPL (Delorme GPS) menu option.
3. Specify the input data and menu items, discussed above.
4. Click the Process button.

The program will import the point coordinate data and display it in the datasheet.

Tips: Once imported the points can be represented in a map using the Map | EZ Map program.
