How to record the RMS value displayed in iCMTGIS PRO?

In the “Enable the External GPS” mode, iCMTGIS PRO can display on the GPS Status line the RMS value sent over by such GPS receivers as the iSXBlue II GNSS, SXBlue Platinum and the EOS Arrow series GNSS receivers.

Some iCMTGIS PRO users have requested the ability to save the GPS RMS information along with the recorded Features. We are working on adding the RMS value and some other GPS status information to the built-in Attributes List. When the new built-in Attributes List is available, you will be able to select the RMS from the list and add it to the Feature Topic as an Attribute. Then the RMS values for the Features recorded via the GPS Data Collection function will show up in Sheet View, and you will be able to export them along with the other Feature information.


How do I get acreage and Feature ID labels to show up for all of my area features?

The iCMTGIS III, iCMTGIS PRO, Forester GPS GIS II/III, Farming GPS GIS II/III and Utility Data Collection apps provide the Auto Label function on the Topic menu as well as the ability to add acreage as an attribute for a Feature Topic.

First, turn on Topic View and tap on the Topic of interest to highlight it.

Tap on the Topic Menu and select Edit Topic. Tap the Add button and select the built-in Area_Acres attribute from the drop-down list. Tap on OK.

Now tap on the Topic Menu and select “Auto Label“.

In the Auto Label screen mark the “Feature ID” check box and the check box for Area_Acreas in the Attribute List. Tap on OK.

The labels should show up in Map View.

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.

Use iCMTGIS PRO to export date and time of the collected points

DateTime-512“We need an export file that contains the collected data along with the date and time of the collected point. Is that possible?”

For the points recorded via GPS data collection iCMTGIS PRO and iCMTGIS III will let you add the date, time and coordinates as Attributes for the associated Feature Topic. These Attributes will display in Sheet View, and they can be exported to Shapefiles and text files.

So, within iCMTGIS PRO and iCMTGIS III, you can have the time, date and the coordinates displayed in Sheet View by doing the following:

1. In Topic View, select the Point Topic of interest.

2. Select the Topic Menu tool then select Edit Topic.

3. Tap the Add button to add a new Attribute.

4. Tap the down arrow then select UTC Date (or Local Date as the case may be).

Repeat to add UTC Time and any other Attribute on the built-in Attributes list.

iCMTGIS II and iGPSGIS II will only display the data/time information in the Feature Properties screen. However, if you have the companion PC-GIS software, then you could add date, time, coordinates and other built-in Attributes to the Topic structure and display and export such data. The function to use is Sheet – Setup.
