CMT PC software and iOS app compatibility

Many of the MARCH-II-E, MC-GPS and ALTO-G12 GPS data collectors have switched to using our iGPSGIS II, iCMTGIS II, iCMTGIS III or iCMTGIS PRO apps. We are pleased to receive their positive feedback.

“We are enjoying using the iPad App and our upgraded version 9 of PC-GPS.”

If you are using PC-GIS 9, PC-GPS9, PC-MAPPER 9 or CMT-Forester 10, these software programs are compatible with the GPS/GIS mapping data collected using iGPSGIS II or iCMTGIS II.

The CMT PC mapping software program compatible with iCMTGIS III, iCMTGIS PRO, Forester II/III is PC-GIS X. They can share the .pmp Job files and the .fbr Feature Lists.

If you wish to continue using your PC-GIS 9, PC-GPS9, PC-MAPPER 9 or CMT-Forester 10 software programs to work with data collected using iCMTGIS III, iCMTGIS PRO or Forester II/III, you can export the Feature Data to Shapefiles then import the Shapefiles to PC-GIS 9, PC-GPS9, PC-MAPPER 9 or CMT-Forester 10. These PC software programs cannot open the enhanced .pmp and .fbr files created by the iCMTGIS III, iCMTGIS PRO and Forester II/III apps.


How to install field software onto the PDA without using WMDC

Windows Mobile Device Center (WMDC) facilitates communication between your Windows Mobile PDA device and your PC. Although Microsoft has stopped supporting the WMDC, we encourage you to use the steps provided in our 7/5/17 blog post to get it working with your Windows 10 operating system.

Some users prefer to use Bluetooth for data file transfers instead of bothering with fixing the WMDC issue for their PC. Should they need to reinstall the CMT field software on their PDA, they won’t be able to do so by using our field software installation program, which relies on the WMDC. In this case, you can download the .CAB files for the field software program from our http site, transfer them to the PDA then double-click on each .cab file to run it. There are two .cab files associated with each field software program. One of them is called If you have previously installed the field software on the PDA, then there is no need to run to reinstall the fonts.

How to delete a Node from an Area or Line Feature in COGOCAD PRO

“I have been pulling my hair out and have exhausted many attempts to figure this out.
I can insert a node into a feature, like a line, but I can not find any way to delete one…Is there a way?”

No need to pull your hair out. Simply email us your questions.

On the tool bar is a Cut Node tool. First click on the Area or Line Feature, then select the Cut Node tool and drag the scissors symbol across the node that you wish to delete.

Same method works in PC-GIS 9, PC-GIS X, PC-GPS 9, PC-MAPPER 9, PC-MAPPER AI and CMT-Forester 10.

How to turn Topic layers on/off in CE-CRUISE 10

The Feature Topics in the map are listed in the Browse Features screen in our Windows Mobile field software. To access the Browse Features Screen in CE-CRUISE, choose Menu/Jobs/Browse Jobs.

In general, feature topics should be arranged by type and size. Point feature topics and line feature topics should be listed first. Small or medium size area feature topics should be listed next. Large area feature topics should be listed last. (An area feature topic on top of a point feature topic may prevent you from seeing the points.)

You can change the order of the feature Topic View by clicking on the desired feature topic name and then clicking on the “Up” or “Down” button to move the feature topic to a different location in the feature topic List.

The mark box to the left of each feature topic name listed in the Browse Features screen is used to specify which feature topics are displayed in the Map View. When you first open your Job file, all of the feature topics in the Feature Topic View will be marked with a check and all of the features assigned to that feature topic will be displayed in the Map View.

GPS week rollover in 2019

It’s been 19.7 years since the last GPS week rollover took place in the year 1999. If you are still using an old GPS receiver for data collection, then after April 6, 2019 the GPS data will be recorded with a much earlier date. Newer GPS/GNSS use 13 bits instead of 10 bits to encode the GPS week number, and therefore will continue to work properly for a much longer time before the GPS week will be rolled back again. The position data will not be affected.

If you are still using the MC-GPS, MARCH-II-E, ALTO-G12, L4 or Z33 data collection systems the data collection dates may be marked with a much earlier date. This creates a problem when you attempt to use PC-GPS to differentially correct the job data. There is no firmware update available for the old GPS receivers in these systems, but we have a fix for it.

Please download from

The udate.exe program is a DOS program that you can run in 32-bit Windows command mode.

It will let you change date in an .ftr file. You will need to know the date your data was collected.

Usage: udate <job file name> <new job file name>

After running udate, make a copy of the files associated with the .ftr job file (*.def and *.raw) then change the job name to be the same as the above <new job file name>.

Then perform differential correction on the files with new job file name.

Users of other makes of older GPS receivers, who make use of the date the data is collected, will need to be aware that the date is wrong. They could output the data to a program such as Excel then use a formula to modify the date for their record keeping.

Some manufacturers of newer GPS receivers have issued statements that their GPS/GNSS receivers will not have an issue with respect to the 2019 GPS week rollover. Others are working on firmware to update their older model receivers. You can check with the manufacturer of your GPS/GNSS receivers to see if there will be a firmware update.

If you collect GPS data after April 6, you will see for yourself whether your GPS receiver has this issue.

(4/8/19 update: MARCH-II-E still gets a good almanac and collects data with the correct date/time.)

Windows 10 S not the same as Windows 10

“I would like to transfer a licence of PC-Mapper 9 on a new Tablet Windows 10 that we prepared. Old Tablet ALGIZ7 with windows 7 to new MS-Surface windows 10.”

MS-Surface runs Windows 10 S, which is different from Windows 10. PC-MAPPER 9 will run in Windows 7, Windows 8 and Windows 10, but not in Windows 10 S.

How to use the Digitize Feature function in PC-MAPPER AI 4.0 to select an Area Feature

” . . .we are looking to improve our aerial survey. An observer drawing near to 1000 polygon a day and that requires a lot of effort. So in areas already know for large insect disease, instead to draw delimitation of the defoliation, we would like attribute a value in a preset polygon with a point tool.”

The Digitize Feature function in PC-MAPPER AI 4.0 is a valuable tool that helps users carry out an airborne inspection. It permits the user to quickly digitize a Point Feature and select the appropriate attributes from a pre-defined Feature List. The user can also digitize an Area Feature and assign the relevant attributes.

The user who sent in the above question wonders if it would be possible to select an existing polygon and tag it with preset attribute values.

It is not possible to select an Area Feature within the Digitize Feature function. However, there is a way to quickly digitize an Area Feature based on an existing Area Feature.

In your Feature List, you can define an Area Topic for the preset polygons and define the desired attribute Values for them.

While using the Digitize Feature, when you select this Area Topic, you can mark the “Include Line/Area Boundary” option in the Digitizing Options window. Then you can click on the preset polygon, create the digitized Area Feature in one second then assign the appropriate attribute value to it.
