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.

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 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.

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.

Quick way to measure acreages using GPS

GPS Data Collection for Area Feature

                                      GPS Data Collection for Area Feature

“I currently have iCMTgisII on my ipad. I am looking for the simplest and quickest way to measure acreages using track points. what is the quickest way to achieve this using that program?”

You can use the GPS/Collect function to record an Area Feature while walking or driving along the perimeter of an area you wish to measure. The standard procedure is to first define a Feature List suitable for your project to facilitate data collection. However, if you just want to quickly map an area, you can use the following steps.

1. Tap on the GPS icon then select “Turn GPS ON“. Wait 5 – 10 minutes for it to stabilize..

2. Select GPS – Collect.

3. Tap on the “Area” tab.

4. Enter the Feature Topic Name, such as “area”. The app automatically assigns “area001” as the first Feature ID.

5. Tap on the Store button in the data collection panel then start walking. By default, one GPS fix will be recorded per second.

6. When you have walked around the area and come back to the starting point, tap the Stop button.

7. If you want to record another area, go to the start point for that area and tap on Store. The app will have assigned area002 as the Feature ID for this second area.

8. When done with the data collection, tap on the Exit button.

9. Back in the Map View, tap the Zoom-Fit icon to see all the areas in the screen. Tap on one of the areas to highlight it. Tap on the Feature Properties icon then tap on the “Length/Area” tab to see the perimeter and area values.

One thing to note is that the GPS on your iPAD is not quite accurate. It is probably fine for measuring very large acreages. For better accuracy (2-5 meters), many of our app users use a compatible external GPS receiver, such as the Dual XGPS-150A or the Bad Elf GPS. GPS receivers that provide sub-meter accuracy, such as the iSXBlue II and the EOS Arrow, have a higher price tag.

What does a .pmp job file include?

The Job file (*.pmp) includes the Feature coordinates, attributes, Shapes, symbols and any labels. When you open a previously saved .pmp file, it will display the same as when you saved the job.

For those of our apps that export to DXF or Shapefiles, the coordinates, attributes and shapes will be exported. The default symbol and line style will be used for the exported data.
