GBM Portable V8
3.2.2.4 Map Projection sub-tab
Maps are normally displayed in the map projection described in the
geoset or workspace they were opened from. Use this tab to change the projection for
displaying the selected map. Changing the map projection does not affect the
underlying data.
Users are only allowed to choose projections that are listed in the set-up file
locate_projections.xml (as configured through the GBM Administration Console) or the
projection defined in the workspace or geoset file the map was opened from.
3.2.2.5 GPS sub-tab
Use this sub-tab to connect and configure a GPS unit. Once configured, the
GPS may be used for moving-map display, drawing custom form objects through the
Drawing tab in Custom Forms mode or moving map features to the current GPS
location. It is also possible to maintain a separate log of GPS location as they vary with
time.
Click Enable GPS to allow GBM Portable to use GPS input. The GPS unit will need to be
delivering NMEA format GPS data, either through a physical connection (RS232 serial
port or USB Port), or through a wireless port such as Bluetooth. It may be necessary to
configure the Bluetooth wireless settings before GBM Portable can detect the GPS.
GBM Portable will attempt to read GPS locations from the communications channel on
which the GPS was last located. If NMEA GPS data is not detected, GBM Portable will
scan available communication ports and will auto-configure to read GPS locations if a
suitable NMEA device can be located.
Click Connection Settings to manually set communications settings manually or take
more direct control over port scanning.
GBM Portable expects a NMEA GPS that outputs locations in the WGS84 projection.
GPS configuration shares software components with GBM Mobile. For further
information on GPS connection and trouble shooting, refer to Appendix IV which has
been extracted from the GBM Mobile user manual.
The status of the connected GPS, the current co-ordinates and the offset between the
current GPS location and the active waypoint are all shown on the GPS sub-tab.
The current way-point can be set through the waypoint tool button. This button is
added to the tool bar at the top of the map when the GPS sub-tab is selected.
