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).


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.

Unable to connect to Google Earth using PC-GIS X

“For the past several weeks we have not been able to load google earth imagery in the software on the pc. It says failure to connect. Has something changed?”

Sometimes an automatic Windows update may change the registry on your PC. When Google Earth is not registered properly, our PC software will not be able to connect to it.

Please log into your PC as the administrator.
Click on the Windows icon and enter “cmd” in the Search box.
Run cmd.exe to open a Windows command prompt (a black screen).

At the command prompt type the path for the folder in which Google Earth is installed. For example, type

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

then press the Enter key on your keyboard.

If your googleearth.exe is installed in a different folder, please enter that full path on the PC in the above line. Please do no omit any quotation marks. There is a space before /RegServer in the above line.

Should you get an error message about your not having administrative privilige, you could put the above line into a text file and save the text file as RegisterGoogle.cmd then right-click on this file and choose “Run ad administrator”.

Now run Google Earth then try using PC-GIS X to Launch Google Earth then zoom into the area of interest and capture an image.

Windows 7 issue – Program won’t run.

“I successfully downloaded and installed PC-GIS 09. However my Windows 7 PC will not execute the software program.”

This problem is due to the Windows 7 security setup. You can resolve it as follows:

First, uninstall PC-GIS 09 by using Windows – Control Panel – Programs – Uninstall Program.

Then right-click on PCGIS9WEB.exe and select “Run as administrator“. When Windows 7 informs you that PC-GIS is trying to make changes to the system and do you want to execute it, in that pop-up window there is a link to change the security level. Please change it to 0 (zero) then select Yes. The installation should go through and the program should run.

Same for installing PC-GIS X and our other PC application software programs.
