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.

“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.

A user received an error message about not having administrative privilege to run this command line. If you get this error message, 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. If successful, zoom into the area of interest then capture the image.

User’s response: “That fixed it! I greatly appreciate your assistance.”

How to use iCMTGIS PRO to collect the points I require and then export the X, Y and Z data in a spread sheet?

1. Make sure your Arrow device is paired and connected with your iPhone/iPad as per the manufacturer’s instructions.

2. Under Setup – GPS mark the check box for Enable the external GPS, select the EOS GNSS receiver and use the protocol named com.eos-gnss.positioningsource.

Setup the threshold values accordingly (PDOP, RMS, etc) based on required accuracy.

Tap on the GPS icon at the top and select Turn GPS On. This will connect the app to the GPS receiver.

When prompted, select “Allow”.

3. Tap on the Topic Menu icon at the top and select New Topic.
Change the Topic Name to “GCP” for example.

Tap the Add button and change the Field Name to Control Number.
Tap the Add button then tap the little pull down arrow and select Position_X.

Tap the Add button then tap the little pull down arrow and select Position_Y.

Tap the Add button then tap the little pull down arrow and select Elev_Z.

Tap on OK.

4. Tap on the GPS icon at the top and select Collect.

5. Tap on the New button then tap on the little pull-down arrow and select your Topic Name (e.g. GCP).

6. The longer you occupy a station, the better the accuracy of the averaged position. Default is 20 seconds. This means you will stay at that location for 20 seconds without moving the GPS receiver.
Tap on OK.

7. Double-tap the Control Number field and enter the GCP number.

8. Tap the Store button. The app will start collecting GPS fixes.
At the end of the session it will store the point location.

9. Go to the next GCP and Tap the Store button to record that point.

10. When done recording all the points, tap the Exit button.

Tap the right-most icon at the top to display Sheet View.
This is the data you will be able to export.

Tap on Main Menu and select Job then select Export.
Select the Excel file format.

If you would like to export data to a text file, then tap the Topic Menu icon at the top then select Export Text File.

Tap the Export Preview button to see what you will be getting in the text file. Tap on OK to complete the export.

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.

Using iCMTGIS PRO and EOS Arrow Gold to collect UAV ground control point data

“I have a UAV company and do lots of inspections and mapping with my drones, when I am doing the mapping in the past I have hired crews with total stations to get me my GCP’s so now I want to do this myself. I get the X, Y and Z data from them so I can input them into my Pix4D software. I know your software allows me to collect the X and Y data but can I also collect the Z data accurately?  . . . . .  Please see the attached GCP information sheet I get from survey companies. As long as I can get this data it will be great.”

These appear to be the coordinates for Point Features. So, you will want to first set up the coordinate system and distance unit to use. If you are using UTM, select the proper zone.

Now create a new Point Topic and give it a name, such as GCP (for ground control point). Then Edit the GCP Topic and add the built-in Attributes: Position_X, Position_Y and Elev_Z as well as the GCP ID attribute.

With the GCP Topic selected, turn on GPS and record a few points. After ending the point data collection, you can turn on Sheet View and look at the data in a spread-sheet arrangement.

You can export the point coordinates and attributes data to Shapefiles or a text file.

As the GCPs are control points, you will need to use the Arrow Gold GNSS receiver in RTK mode to get better accuracy.

Under Setup – GPS, select “Enable the External GPS” and select the protocol for the EOS GNSS receiver. This way, you will be able to see the RMS error of the GPS data output by the GNSS receiver displayed at the top of the Map View screen.

How to use iCMTGIS III to check GPS accuracy

“I have purchased the iCMTGIS III and I am using a TIFF image as a background map. I am having problems with the GPS not very close to a known point. Do you have any suggestions? I am using a Bad Elf Pro+ as an external GPS it says it is supposed to have 3-5 meter accuracy. Do you suggest another GPS? Is there only one place to change coordinate system or is there other parameters that may need to be changed to get acceptable accuracy?”

Does your iPad come with GPS? Perhaps the iPad is using its internal GPS, which has poor accuracy. Please turn off GPS from all the apps on your iPad. Then, with the Bad Elf Pro+ connected to your iPad and turned on, run iCMTGIS III and select GPS – Turn on GPS.

Another way to ensure that the iPad uses the external GPS is to turn on the Airplane mode under the iPad Settings. For details, please see our blog post at:
https://icmtgis.wordpress.com/2014/03/05/using-an-external-gps-with-icmtgis-ii-on-ipad/

To check the accuracy of the GPS receiver against the LLA coordinates of a known point or survey mark, you could first create a Point Topic then add a Point by using the Add Point by Coordinates function from the Tools menu. Enter the latitude and longitude of the known point. With the Bad Elf GPS having been turned on for a few minutes, check the location of the GPS marker against the known point. The published accuracy is an average value.

To record a Point Feature, please use GPS – Collect and log GPS point data for 5 minutes or longer. The app will compute and display the average point position. Measure the distance between the recorded point and the known point.
