5. From the Handheld Export tab, center the map on the quadrant and customize the handheld
grid size to best fit the area. Then, click the Select/Edit tool and select the grids on the
map that cover the quadrant.
6. Click the Options button and select the check box next to each dataset to transfer to the
Earthmate GPS PN-20. For high-resolution aerial imagery, select XMap Raster Data Snapshot.
For topographic, road, and GIS data, select XMap USA Topographic Data. For scanned historic
maps, select the ImageReg Data series. Customize the display ranges of the datasets based
on your preferences.
7. Name and save the map package. Then, click the Exchange button on the Handheld Export tab
or in the toolbar. Send the mile marker waypoint layer and saved map package containing the
road, topographic, historic, and aerial imagery maps to the device and then click Done.
Using the Earthmate GPS PN-20 in the field
With all the data transferred to the Earthmate GPS PN-20, the field crew for each quadrant is ready
to head into the field to update and verify the utility data. One field crew is responsible for updating a
quadrant with significant additions and changes to the existing infrastructure. They have a list of mile
marker ranges where these changes took place.
1. Use the Routes option on the Earthmate GPS PN-20 to create a route from the field office
(current GPS location) to the utility waypoint mile marker next to the service road entrance.
2. Once the field crew arrives at the entrance, the worker with the Earthmate GPS PN-20 directs
the driver to each mile marker on the list where utility additions and modifications were made.
They use the bearing and distance information for each waypoint to navigate along the service
road. Once they are parallel to a mile marker, they set out on foot to the pipeline, using the aerial
imagery, topographic, and GIS data to give them field reference.
3. Once the line locations are located, the crew collects pertinent waypoints and tracks on the
Earthmate GPS PN-20 to record information about the line. They use the various waypoint
symbols on the Earthmate GPS PN-20 to represent different features, such as areas in need
of service or areas where there are dangerous trees that need to be removed. When they
come across an area where the GIS data does not correlate with the location of the utility line
in the field, they record a track for that length of segment and drop waypoints at each line vertex.
4. When the field crew is finished, they return to the office and download the waypoints and
tracks to XMap. Then they review the data to update any labels that need clarification and put
additional notes for the points using the mapnote feature in the Draw tab.
5. Once they are finished with the review, they synchronize their field data to the central database
using the synchronize feature in XMap.
6. The next day, the database manager responsible for the division reviews their synchronized
data against the corporate GIS layer and updates the corporate layer within XMap.
