Question about Feature List setup in CMT iOS app

“What’s the Feature Lock function on the top right of the Feature Editor tab? You can check or uncheck that option and really not sure what is that about.”

When the “Feature Lock” check box is marked, you can only select from the Features defined in the Feature List. When unlocked, you can add a new Feature Topic on the fly to collect data for it.


Is there a video tutorial to show me how to set up a Feature List?

We’ve just uploaded a new video tutorial. Here you go:

How to create a data dictionary using iCMTGIS PRO

“I would like to ask about the ability for our software to provide the data dictionary? If yes, what is the process please? One of the engineers send me a sample shape file from the distribution assets at xxx, he asked if we can do data dictionary for him. Another question please, is it required to have the desktop version for icmt to develop the data dictionary or it is enough to have the iPad software?”

The Feature List functionality under the GPS tab of iCMTGIS PRO is for setting up one or more data dictionaries. The section on Feature List in the iCMTGIS PRO Help document describes this function and provides an example for creating a Feature List.

You can use iCMTGIS PRO or the desktop PC-GIS X to set up a Feature List. The Feature List file has the file name extension “.fbr“.

After a Feature List has been saved in iCMTGIS PRO, you can select it for any Job you do on iCMTGIS PRO.

You can open the engineer’s sample shape file in iCMTGIS PRO and look at the data records in Sheet View to find out what Values they have assigned to each Attribute. However, these are just the Values used during one data collection session and may not cover all the Values they have defined for the Attribute. The engineer should provide you with the full structure of the data dictionary.

How to use the Feature List in iCMTGIS PRO?


“Hello, I have just purchased ICMT GIS Pro, loaded on an IPAD mini, and using an EOS Arrow 200 GPS. I created a feature list and saved it, I can open the feature list in a new job, but if I go to collect data I can’t get the feature list to come up. Is there a step I am missing?”

The following information applies to iGPSGIS II, iCMTGIS II/III/PRO, Utility Data Collection, Farming GPS GIS II/III and Forester GPS GIS II/III.

Please tap on Main Menu then select Job – Open Job.
You will see the Feature List field. Right now it’s probably showing “NONE”.

Tap on the little pull-down arrow for this field. You should see the name of the Feature List that you have created. Select that Feature List then tap on “OK”.

Now, when you use GPS – Collect and tap on “New”, you can tap on the pull-down arrow for the Feature Name field then select from the Features defined in your Feature List.

You can associate any Job with any one of the Feature Lists that you have created.

Feature Attribution in iCMTGIS III

“When we start collecting data by Collect button a separate window is displayed to the bottom of the screen, showing our added field names, but when we store a point, there is no data seen in that table, however if we use the table icon at the left top of the iCMT, the data is present there, this may give a bad impact if this is without reason.”

The Attribute fields you’ve added to a Topic are for tagging any Features in the Job file.

The Attribute fields for GPS Data Collection need to be defined in a Feature List, which you can associate with any Job file.

When you do Job – Open Job, you will see the Feature List field. Right now it’s probably showing “NONE”. You could select the built-in Feature List “utilities” (in iCMTGIS III) to work with and collect data for the Features defined in that Feature List.

To make your own Feature List with your own Features and Attributes/Values, please select GPS then select Feature List. Here After you select “New”, you can define the type of Features (Point, Line or Area), the data collection parameters and the Attributes and predefined Values for those Features.

While you collect data using the Feature List, you can select or enter the Attributes for the Feature being recorded. These Attribute/Values will display in Sheet View at the bottom of the screen (if you have activated Sheet View display by tapping the Sheet View icon on the right side at the top.)

File types used by CMT software

Now that more and more of our customers are using our PC mapping software in conjunction with our apps for the Windows Mobile devices and the iPad and iPhone devices, this is a good time to talk about the relationship among some of the main types of files used on the various software platforms.

1) Feature Coordinate Files – .ftr files

Our PC software stores the GPS coordinates for a job in a .ftr file.

2) Feature Map Files – .fmp files

Our PC software stores the GPS coordinates as well as non-spatial map elements (such as symbols and colors, links to background maps, etc.) for a job in the .fmp file.

3) Portable Map Files – .pmp files

The .PMP files are Portable Map Files for use on the mobile devices, such as a Windows Mobile device or an iOS device.

After loading a .FMP map file into our PC software, you can select File – Save As then select the .PMP file type in the “Save as type” box at the bottom of the dialog window. Enter a file name then click on “Save”. At the top left side of the screen, you will see that the job name now ends in .pmp.

The .pmp file is what you can transfer to your iOS device for use with a compatible CMT iOS app.

4) Background Maps

In our PC mapping software, you can use the following as background maps:
Raster Images (geotiff, geojpeg, MRSID, ECW)
CMT Basemaps
Geo-referenced image captured from Google Earth

Our iOS apps use the built-in Apple Map as reference map. This Map is available when the Apple Location Service is available. You can turn it off by using Main Menu/Map/Close Map. You also have the option to select a Satellite map or a Standard map. This is described in the Help file under the Main Menu of the app.

The Apple Map may not be totally up to date. Therefore, if you have a good geo-referenced raster image, and you have a CMT iOS app that provides the Background Map function, you can use our PC mapping software to convert the image to a .pim file to use on your iOS device. This is discussed in the next item below.

5) Portable Image Files – .pim files

The .pim files are the Portable Image files for use as off-line maps on the mobile devices. You will need to use a CMT PC mapping software program to create the .PIM files. In your PC-GIS X software, this function is under Utilities – Mobile Device Interface/Image Converter.

Under Help is an Online Manual. Please enter CE Image Converter in the Search box and follow the instructions to create a .pim file for a map that you have loaded into the PC software. You will be able to select just a small portion of the map that you need to make a .pim file for use on your mobile device.

To make the .pmp and .pim files available for use by your iCMTGIS II, iGPSGIS II app, Farming GPS GIS, Forester GPS GIS or Utility Data Collection app, you will need to copy them to the shared files folder for the respective app. To load a .pim file into one of these apps, select Main Menu/Background Map/Load Registered Image then select the desired file.

6) World Files – .wdf files

You can download geo-referenced raster images for use as background maps in your CMT PC mapping software from such a site as

Before loading a geo-referenced image, you will need to set the datum, coordinate system and distance unit in your CMT PC software to match those that were used in creating the geo-referenced raster images (e.g. UTM NAD83 Meters).

When you load a map image, the CMT mapping software will ask you if you would like to have a .wdf file created. With a .wdf (world file) created, in the future the software will load the map without prompting you for the coordinate system. However, if a .wdf file was created when the map was loading incorrectly, then you must delete the bad .wdf file then reload the map in the correct coordinate system. Otherwise the software will keep using the bad world file as a reference and load the image incorrectly.

7) Feature List Files – .fbr

The Feature/Attribute/Values data base used by the CMT apps are stored as .fbr files.

8) Other file formats

Certain apps may also save or export data in other file formats, such as .dxf, .txt, .csv, .dcf, .lnd, and so on.

Many of our iOS apps can import Shapefiles, and some of them can export data in Shapefile format, which involve such file name extensions as .shp, .shx, .dbf and .prj.
