Where to get Digital Elevation Model files for use in PC-GPS?

“Looking for a new place to get the DEM files that work in PCGPS. The geocomm site I used to use appears to be out of business.”

“Can you remind me how to remove the tan color from the background on the base maps? This uses a lot of ink. Just need a white background.”

Under Basemap – Basemap Options please turn off “City Limits” and “County Subdivisions”.

Microsoft stopped supporting Windows Mobile Device Center (WMDC)

“My handheld device (Trimble Nomad) and my computer will not connect, apparently a result of a recent Windows update, despite numerous uninstals, installs, repairs. I have tried copying my data to a flash-drive but I don’t know how to then open it in CMT Forester. The job shows on the flash drive as a .fix file. Can you help?”

Microsoft stopped supporting Windows Mobile Device Center (WMDC) with the Windows 10 version 1703 update.

There are several files associated with each CE-CRUISE 10 job. The two essential files you must transfer to the CMTForester folder on your PC are: the .pmp file and the .crz file.

You could try to fix the issue with Mobile Device Center on Windows 10 as follows.

1) Add 2 registry entries as shown below by putting them in a text file
then right-clicking on the file name (such as WMDC-Reg.bat) and selecting
“Run as administrator”

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\RapiMgr /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WcesComm /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

2) Restart the PC.

3) Click on the Windows Start icon and right-click on
Windows Mobile Device Center.
Select “Run as Administrator”.
Now WMDC 6.1.6965 in Windows 10 version 1703 runs, but it shows
Click on Mobile Device Settings then click on Connection Settings.
Mark the check box for “Allow USB connections”.
Unmark the check box for “Allow connections to one of the following:”.

4) Right-click on Windows Start icon and select “Computer Management”.
Double-click on “Services and Applications” then double-click on “Service”.
Scroll down and look for “Windows Mobile-2003-based device connectivity”
and “Windows Mobile-based device connectivity”. Double-click on one of these
services to view its properties. Click on the “Log On” tab then
select “Local System account” as the log on mode.
Do this for the other mobile-based device connectivity service as well.

Restart the PC.

5) On a PDA running Windows Mobile 5.0, tap the Windows Start icon
then select “Settings”.
Tap on the “Connections” tab.
Unmark the check box for “Enable advanced network functionality”.
Select “USB Settings” then select “Transmission as Serial Interface”.
Now connect the PDA to the PC via USB.
The Mobile Device Interface in PC-series will show that the
PDA and the PC are communicating properly.

WMDC may still show “Disconnected”. It will show “Connected” after a restart.

On PDAs running Windows Mobile 6.0, after selecting “Connections”,
tap on “USB to PC”.
Mark the check box for “Enable advanced network functionality”.
If successful, connect the PDA to the PC via USB and verify that PDA and PC are able to communicate with each other.


Should the above steps not work for your system, or should another future Windows update wreak havoc again, you could copy the job files from the PDA to a flash drive then copy them from the flash drive to your PC.

For FieldCE-GIS and FieldCE-SURVEY, copy the files ending in .pmp. (If you are using the old Z33 system with FieldCe-SURVEY to record raw data for differential correction, then also copy the .raw, .def, .ftr and .fix files.) For CE-CRUISE 10, copy the .pmp and .crz files.

You could also try using Bluetooth to transfer files between the PC and the PDA. If your PC is not Bluetooth enabled, you can get a USB dongle to add the Bluetooth capability to your PC. However, it’s a rather clumsy process to move the files yourself through the finicky Bluetooth connection.

How to display the auto labels without the point symbols

In our current PC mapping software, the auto labels are saved on the same layer as the Features rather than on a non-spatial (Shape Only) layer. A customer labels areas over a raster images by using points that are auto-labeled with section numbers. He wants to know how to have the labels shown without also displaying the symbols for the points.

To display the auto labels, the points also need to be displayed. A solution for this situation is to delete one of the point symbols on the symbols page in the Point properties window. This “empty” symbol could then be used for the auto-labeling purpose and not show up in Map View.

Registering Google Earth

“I’m having trouble with step 4, can you explain in a different way? I don’t quite understand it. Thanks.”

In our blog post dated 2/16/17, Step 4 is to register the Google Earth program with your PC.

First, use the Search function on your PC to look for a file with this name:


In most cases, it will be located in this file folder on your PC:

c:\Program Files (x86)\Google\Google Earth\client\

Now use a text editor such as Notepad to open a new file.

Type this line into the text box:

“c:\Program Files (x86)\Google\Google Earth\client\googleearth.exe”

This is all one line without any breaks.
You must enter it exactly as shown, including the quotation marks.

If the actual file path is

c:\Program Files\Google\Google Earth\client\googleearth.exe

then substitute this part in the above text line in Notepad.

Make a temporary folder on your PC, such as TEMP.

Save the above text file in this TEMP folder using a name that ends in .com, such as


To run this file, right-click on its name and select “Run as administrator”.

Cruise Default Setup

“In the cruise window I cannot include/ exclude stands in the new download. The button is grayed out.”

Please go to the Cruise – Default Setup page of CMT Forester 10 and un-mark the “Disable the Exclude/Include Toggles” check box.

UTC Time Offset for GPS Data Collection

Now that we have sprung forward to Daylight-Saving Time, if you are still using the old CMT GPS data collectors, please remember to reduce the (absolute value of the) UTC Time Offset setting by 1 hour. For example, if it was previously set to “-8”, change it to “-7”.

As many of our GPS data collector users have switched to using iPad, iPhone, iPod touch devices and our iGPSGIS II or iCMTGIS II data collection apps, we suggest that you also consider moving to the new hardware and software if GPS differential correction is not required.

iGPSGIS II (for iPhone) and iCMTGIS II (for iPad) are compatible with the PC-GPS 09 software. The new system provides real-time GPS positions and does not collect raw data for differential post-processing. As the built-in GPS receivers on iPad and iPhone devices do not provide good accuracy, most users purchase an external Bluetooth GPS receiver (such as the Dual XGPS-150A or the Bad Elf GPS ) to use with our app. These claim 2-5 meter horizontal position accuracy. iSXBlue II GNSS and the EOS Arrow receivers claim much better positional accuracy (and are much more expensive).
