Forester GPS GIS III updated to Release 1.0.3

In Forester GPS GIS III 1.0.3, we fixed an issue involving Location services permissions, which disabled GPS data collection using iPad devices running iOS 12.

We have also enhanced the text file import and export functions. Whereas text file import was limited to importing text files ending in .txt, now the user may choose the .txt or the .csv file name extension. For text file export, instead of exporting all of the Attributes for the Topic, the app now provides a dialog to let the user select specific Attributes to be exported.

How to include Latitude and Longitude for text file import

iCMTGIS III, iCMTGIS PRO, Utility Data Collection, Farming GPS GIS III and Forester GPS GIS III will let you import data into a Point Feature Topic via a text file. The text file can include latitude and longitude values. How these values should be presented in the text file depends on whether you have selected Degrees or the DMS format as the active angles unit in the app.

With the Degrees format, simply present the LAT LON values as decimal numbers. West is designated with a minus sign ( – ). For example:

30.384550
-87.278860

With the DMS format, make sure the Degree unit is represented by ^, the Minute unit is represented by ‘ and the Second unit is represented by “. For example:

44^32’40.43″ N
123^06’50.65” W

To have these values interpreted as LAT LON coordinates, assign the field names “Latitude” and “Longitude”, respectively.

Generally, you can generate an Export Preview for a similar Point Topic to see how an import text file should be formatted for the options selected.

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.

iCMTGIS II, iCMTGIS III and iCMTGIS PRO comparison

“I’m hesitant to spend $300 for the pro app if the $95 or $200 apps will suffice but I’m having a difficult time finding a comparison of features among the apps.”

Built-in Attributes 512x384

The three apps in the iCMTGIS-series all provide real-time GPS/GIS data collection and mapping functions. They will let you add user-defined Attributes for the recorded Features either manually or via a Feature List (attribute table). They will let you import and export Shapefiles. The differences are in the additional functionality provided by the more expensive apps.

If you just need to use GPS to map Points, Lines and Areas and record their associated descriptions, iCMTGIS II will do. iCMTGIS II can display the built-in Apple Map as background. If you would like to use an off-line geo-referenced background image, you will need to first use the optional PC-GIS software to convert the GeoTiff, GeoJpeg, ECW or MRSID files to the .pim file format. The .pim map can work in the “moving map” navigation mode. (Many of our existing customers already have the PC mapping software.) iCMTGIS II only works on an iPad device. Its iPhone equivalent is the iGPSGIS II app.

iCMTGIS III and iCMTGIS PRO can run on iPad and iPhone devices. These two apps will let you load a GeoTiff image or a .pim image as background map. They also provide a built-in Attribute List from which you can choose as additional Attributes for the Features. One of the screen shots displayed here shows the current list of built-in Attributes that you may elect to include in the data records for the Features recorded using GPS. Other additional functions are also provided in these apps, which help you stake points/lines/areas, create Features by entering distances and bearings, as well as classify, sort or perform a search on the Features in a Topic layer, import and export Point Features via a text file, etc.

GPS surveying using iPhone

GPS surveying using iPhone

iCMTGIS PRO has all the functionality of iCMTGIS III plus the Contour/Volume and Create Buffer functions. What sets it apart from the other two apps is that it provides the ability to receive the NMEA message stream directly from a few specific external GPS receivers. When the “Enable the External GPS” option is selected, iCMTGIS PRO will get the GPS information directly from the external GPS receiver rather than the iOS CoreLocation. This enables it to display a GPS status bar in real time.

At this time, EOS Arrow GPS receivers and Geneq iSXBlue II + GNSS can work in the “Enable the External GPS” mode. To use the EOS Arrow 200 and iCMTGIS PRO for RTK work, you must use the free EOS Tools Pro app to connect to the RTK network.
