How to tell if an app is using Location Services?

The Location Services is shared by the iOS system and all the installed apps.

To check which apps are using the Location Service, please call up Settings\Privacy\Location Services. On the right side of the list of apps look for an arrow mark.

If an app name has a purple arrow mark on the right side, it is actively using the Location Services.

A gray arrow indicates that an app has used the Location Services within the last 24 hours.

iCMTGIS II closes after iOS 10 update on iPad mini

“I have a copy of iCMTGIS II, recently updated/last week, running iOS version 10.2.1 (14D27) on iPad mini/gen 2. With ‘gps on’ and upon tapping ‘Collect’ to collect data, the app closes and doesn’t allow data to be collected. The app remains open in the background, i.e. doesn’t close out, but upon selecting ‘Collect’ again, it repeats the same issue and will not allow data collection.”

We asked the user, “Have you tried uninstalling and reinstalling the iCMTGIS II app?”

The user replied, “the un-install/re-install worked. . . . thought of un-installing/re-installing but had never done that with an iOS app since it is a download from the app store, but now I know I can. thanks!”

It is possible that the iCMTGIS II app was still open when the user did the iOS upgrade. Before an iOS upgrade, it’s best to close out all running apps. You can do so by double-clicking the Home button then swiping up the displayed app screens.

If we do purchase it, is there a charge for future updates/versions of the app?

If the app name and version stay the same (such as iCMTGIS III), there will be no charge for update releases. There are no annual subscription fees of any kind.

Will I lose any job data when I uninstall an app?

Yes. When you uninstall an app, all the job data files will be lost.

Please use iTunes to copy the data files (including the configuration file with the file name extension “.cfg”) to your PC before uninstalling and reinstalling the app. Then copy these files back to the documents folder of the app after reinstalling it.

How to exit the app on my iPad?

When you press the Home button on the iPad one time, the app goes to the background, and you can work with other apps displayed on the Home screen.

To exit any app on your iPad, double-click the Home button, then swipe the screen for the app upward. When the screen vanishes, that app is closed.

Whenever I touch any part of the screen, the app plots an unwanted point.

In the “Add Point manually”, “Add Line manually” and “Add Area manually” screens there is an icon that shows the word “Add“. When it is highlighted, each time you touch the screen, it digitizes that location. If you would like to zoom or drag the screen without adding a point or a node, simply touch the “Add” icon to toggle it off.

Meaning of working coordinate system in iCMTGIS III

“From the help file exported data will be in the ‘working coordinates’. How are the working coordinates defined? USGS geo tiffs are in UTMs. Does that become the working coordinates; or can decimal degrees or state plane coordinates be selected?”

Before loading the USGS GeoTiffs or importing Shapefiles, you will want to select in iCMTGIS III the same coordinate system as that used for creating the USGS GeoTiffs or Shapefiles. Please also make sure to select the proper distance unit.

After loading the USGS GeoTiff or Shapefiles, you can switch to another coordinate system of your choosing, such as SPC.
If you want to see angles displayed in decimal degrees, then under Setup select Elevation and Angle then select Degrees.
