CMT Basemap layers

“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.
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”.
Un-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”.

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).


We need a basemap for YUMA county in Arizona, can you help?

Please download Basemap from

Please copy the entire “basemap” folder to the C: drive of your PC. Select Utilities – Load/Change Basemap and specify the folder “c:\basemap”. You may then select from the listed counties for which to load the basemaps.

To see the basemap, select View/Basemap and make sure “Display Basemap” is checked.
When “Display Basemap” is checked, whenever you open a job, the applicable basemap will be automatically loaded if the basemap resides in the c:\basemap folder of
your PC.

Unable to do differential data correction on data collected using ALTO-G12

“The last time I performed a successful differential correction was a month ago. I have been having trouble with the differential correction ever since. The message it gives me is that there is no data for the base stations. Also, how would I set up the GPS so that it collects raw data?”

In the differential correction screen there is a box for specifying the folder the contains the base files. Make sure that location agrees with where you have placed the downloaded base files

The ALTO-G12 data collector records the raw data by default.

If the base files are not downloaded, the jobs cannot be processed. Did something change on your computer or your network system to prevent the base files from being
downloaded automatically?

Are the firewalls on your PC or an antivirus or antispyware program preventing the ftp access to the NGS CORS site? Please add (or ask your IT person to add)
PCGPS09.EXE to the firewall and antivirus or antyspyware exception lists.

If you are able to access the CORS site outside of PC-GPS 09, you could try the manual procedure for downloading the base files. It is outlined below.
1. You can obtain the CORS Rinex data via non-ftp site through the world wide web. Please use the following address:

2. You will need to download the “RINEX data” and also the “Global Navigation” data (under the non-site specific section) for the day and base station you need.

After downloading and unzipping the data, you will be left with the file extensions: *.17o and *.17n for the 2017 files.
The file prefixes also need to match.
The global ephemeris file has a generic name like: brdcxxx.07n.
Please rename the file prefix to match the *.17o file. For example, if the *.17o file is named: fts11230.17o, then rename the brdc1230.17n file to be: fts11230.17n.

For example PIT1238A.gz is the base file from “Pittsburgh 1” for the first hour (A) of the 238th Julian Day.The unzipped raw correction file is named: PIT1238A.17o.
Rename the ephemeris file brdc1238A.17n to PIT1238A.17n.
Write down the LLA coordinates of the base station.

3. Put the PIT1238A.17o and PIT1238A.17n files in your PCGPS9 folder and point to the folder in the differential correction function.

In the differential correction screen, click the Setup button then select Base Management. Click NEW then add the new base station name and coordinates.

Back in the main differential correction screen, select the base station name.

When you move the rover files into the Selected Jobs section, the matching base files will be highlighted in the Files panel. Then click the Differential button to perform the
differential correction.
