Which product best fits our needs?

“I’m browsing through your website and trying to figure out which product best fits our needs. We run a farming operation that deals with fields of many shapes and sizes. We’re looking for an easy to use solution. Here is our wish list:

1. Non-expensive
2. Integrates with iPhone or iPad
3. Exportable to PC to overlay on Google Maps or other mapping software
4. Sub meter accuracy

Would you be able to point me in the right direction?”

Items 1 and 4 on your wish list are related. The greatest expense you will incur is in the GPS receiver. GPS with sub-meter accuracy cost a lot more than consumer-grade GPS with 2 – 5 m accuracy. The EOS Arrow Gold and the iSXBlue II+ GNSS provide sub-meter accuracy.

Our iCMTGIS III GPS/GIS data collection and mapping app will run on iPhone and iPad devices. It provides the ability to export Feature data as a .kml file that you can upload to Google Earth and Google My Maps. It will also export Feature data in Shapefiles format and DXF file format. Many GIS software provide the ability to import Shapefiles. So does our PC-GIS X mapping software, which will also work with the Job files you created by using iCMTGIS III.

(Farming GPS GIS III provides similar functionality as iCMTGIS III, but it will only run on iPad devices.)


How to get Point ID exported to AutoCAD

“… it seems that the ID name did not come through into AutoCAD. I have the X, Y, Z and feature ID but not the ID we assigned the point in the program.”

How did you assign the ID to the point in the iCMTGIS II app?

With your point topic selected, please Tap on the Topic Menu icon (second icon from the left side) then select Edit Topic.

Tap the Add button to add an Attribute named PID, for example then tap on OK.

Turn on Sheet View (the last icon on the right side).
Now you can double tap a record then tap on the Attribute button to enter the point ID.

Alternatively, if you add this PID field to the Feature List you are using for this Job, then you can enter your point ID while you are collecting GPS data.

The same is true for the Utility Data Collection, iGPSGI II, iCMTGIS III and iCMTGIS PRO, Farming GPS GIS II/II and Forester GPS GIS II/III apps as well as PC-GIS.

How to export elevations to Shapefiles?

“We have the iCMTGISII Ap installed on one of our iPads. We can see the X, Y and elevation data in the Properties tab but when the points are exported to a Shapefile, the elevation data does not get exported. How do we get the elevation data exported with the Shapefile to be displayed in either ArcGIS or AutoCAD?”

In the Export Shapefile screen, please mark the check box for “3D” if you want the elevation data exported as well.

Where can I find the Shapefiles on my ipad after they have been exported?

The Features in each Topic layer are exported to one set of Shapefiles. The exported Shapefiles are stored in the Documents folder for the app (e.g. Forester GPS GIS II, Farming GPS GIS II, iCMTGIS II, iGPSGIS II, Utility Data Collection).

Before exporting the Shapefiles, please check the iCloud setting in your app. If the checkbox for “Job” is marked, please unmark it. Otherwise the app will export the Shapefiles to iCloud storage instead of the local folder.

To get to the Documents Folder:
1. Sync your device with your PC/MAC via iTunes.
2. In iTunes select your device then select “Apps” . Scroll down to the Shared Documents section and select your CMT iOS application program.
3. You will see the files that are stored in the Documents folder for the app on your iPAD (or iPhone), including any Shapefiles files.
You can highlight the files you want to save to your PC then click the Save To button and select a folder on your PC to copy the files to that folder.

Remember to copy all the Shapefiles (*.shp, *.shx, *.prj, *.dbf) for each Topic.

iCMTGIS III, Farming GPS GIS III and Forester GPS GIS III will let you export the Shapefiles for a Topic to a sub-folder in the Documents folder, making it a bit easier to find all the files for a Topic in one place.

How to get all the points in one shapefile rather than a shapefile for each point?

Some of our apps can import and export Shapefiles.

Each Topic layer gets exported to one set of Shapefiles. Each Topic layer should only contain Features of the same type (such as all Points).

In the GPS Data Collection routine, after you have selected a Point Feature Topic and recorded a point, tap the Store button to store the next point on the same Topic layer. (If you tap the New button, the app is expected to record data for a new Topic layer.)

Where are my Shapefiles?

An iCMTGIS II user wrote: “In the documents folder the only files visible were library folders. There were no Shape file associated files.”

Under Setup – iCoud, please un-mark the check boxes then tap on OK.
Export the Job data to Shapefiles then look for those files in the Documents Folder of iCMTGIS II.
When you have the check box for Job marked, the exported files will go to iCloud storage and not be in the local documents folder.

Is the iGPSGIS II app compatible with ArcGis ? I want to use the app to collect sampling location in NAD83.

iGPSGIS II can import and export Shapefiles. It will also let you select the datum and coordinate system to work with.

After recording the sampling location in NAD 83, you can export the data to Shapefiles for importing to ArcGIS.
