Map not showing up in iCMTGIS PRO on iPhone 7 (iOS 10.3.3)

“I purchased the iCMTGIS PRO program about a year ago and have used it since then and like it and now I cant get a map to display I have good internet access when I go to Menu, map, and select show satellite or hybrid it just shows a gray background? Any idea how to fix this? If I close map the background goes to white. I have Version 1.0.6. I have tried closing the program , rebooting the iPhone etc. and cant figure it out? My job points show up but no map?”

Support: Please try using the Maps app on your iPhone. Does it have the same issue?

User: Google maps works but the other map won’t show.

Support: By “the other map” do you mean the Maps Apple app? Yeah, sometimes there is a problem with the Apple Maps server. However, it is working at our location in Oregon. Please try again tomorrow and see if the issue has been resolved.

User: Ok now it works I updated to iOS 11 and now it works – not sure if that did it or it just came back online

Support: Apple Maps must have come back online. The Map function in our apps is based on the Apple Map.

If you have a Geo-Tiff image for your job site, you could load it into the iCMTGIS PRO app as a Background Map. Background Maps work off-line.


Map only shows grids in Partition & Stakeout app loaded on iPhone 7

“Downloaded app from Apple Store on July 13th 2017. Still reading and learning usage of software. Although, in attempting to use the Maps portion with GPS, no maps appear, strictly grids. App loaded on an iPhone 7; version 10.3.2. Can you assist with possible issues for correction? This is for personal usage, not commercial. Would like to stakeout and layout lot for new home.”

The Map function gets the map from Apple via wi-fi. Sometimes it helps to turn off wi-fi on your iOS device then turn it on again. Resetting the iOS device usually corrects the problem.

Please run the Apple Maps app on your iOS device. If you see the same screen of grids, then the issue should be due to the Apple Map server or a network problem.

Map cannot zoom in past 2 cm : 13.70 Meters in iCMTGIS PRO

With the built-in Apple Map turned on, you cannot zoom all the way in. This is a limitation with the Apple Map.

Please turn off the Apple Map. You could use a Geotiff or a .pim file as the background image instead.

GPS marker goes to (0,0) after updating app

“After we upgraded our iCMTGIS III to its latest version, v1.1.3, we had two funny behaviors:
1) Two of our staff can’t get GPS right (pointing roughly to 0,0) – other apps on iPad give correct locations; I couldn’t find which setting affected it. So remove the app and re-installed, and the GPS location read right.
2) Google Apple Standard Map slowly refreshed or doesn’t show at all (but satellite image is fine).”

1) We checked into this issue and saw the problem on one iPad after we updated it from iOS 8 to iOS 9.2.1 yesterday. (It worked fine before the iOS update.) Somehow the Datum and Epoch fields under Setup – Coordinates were blanked out. After we selected the GS84(1150)/ITRF00 datum and entered 01/01/2015, the GPS marker was displayed in the correct location. Our app does not let the user blank out the Datum field. It saves this information with each Job. A new job created defaults to the WGS84(1150)/ITRF00 datum. We updated another iPad to iOS 9 yesterday but did not see this issue afterwards. It is possible that the problem occurred in the other iPad because we forgot to close the app before doing the iOS update. Therefore, to avoid strange problems, it is advisable to close the app before downloading a software update or an iOS update.

2) We have occasionally seen the Apple Map refresh slowly or not show in the “Show standard” mode. We think it is caused by the Apple map server network. Switching to Show Satellite then back to Show Standard usually resolves the problem.

Satellite image obscured by cloud

“I have your app “farming gps gis” for iPad, and can’t use it effectively as the satellite image for our farm has a cloud obscuring the view. Is it possible to access another layer image which would be clear of cloud?”

Indeed the entire farm was blocked from view by white clouds that one would otherwise be happy to see. Hopefully the clouds will have drifted away when Apple updates the Map images in the future.

Our PC-GIS software will let you convert a GeoTIFF , a GeoJpeg, a .SID or a .ECW map image into the .pim format that you can load into the Farming GPS GIS app to use as a background map. It will also let you capture a geo-referenced Google Earth image and convert it into .pim format.
A PC-GIS brochure can be found at

(This user mentioned that he only uses the app on his own farm, so we captured a geo-referenced image from Google Earth Pro and converted it to a .pim file for him to use.)

Can’t zoom in enough

“Im just wondering if its possible to tweak the zoom levels in iCMTGIS III? (cant zoom in enough). I would really like to zoom in on a low level. As for now, its kind of difficult to digitize new features that are as small as a couple of meters. Im using my own geotifs as backgrounds. . . . . . Im using the latest version of icmtgis III on a Ipad mini 3, IOs 8.3, and a ipad 4, ios 8.2.”

If the Apple Map is turned on, please close it by selecting Close Map under Main Menu/Map. Does this help?

“Ah! Problem solved. Thank you very much.”

No background map in exported PDF?

Some of you may have noticed that when the Features are exported to a PDF file, the background image that was displayed in Map View does not show up in the PDF file.

There are a few different types of background maps employed by our mobile apps.

1) Apple Map

The Apple Map comes standard with most of our iOS apps. It is available whenever wi-fi is available. The Apple Map cannot be output to a PDF file. You could, however, use your iOS device to capture a snapshot of the displayed map and obtain a photo file. Then you could use a program (such as Microsoft Word) to insert the photo into a document then print to a PDF file.

2) Portable CMT Background Image (*.pim)

The .pim files are the Portable Image files for use as off-line maps in our iPad, iPhone and Windows Mobile apps. You will need to use the optional CMT PC mapping software program to create the .PIM files from geo-referenced geotiff, geojpeg, MRSID, ECW and captured Google Earth map images. You will be able to select just a small portion of the map that you need to make a .pim file for use on your mobile device.

The Utility Data Collection, Farming GPS GIS , Forester GPS GIS, Farming GPS GIS II and Forester GPS GIS II apps are able to output the displayed .pim background map to PDF.

3) CMT Job map (*.pmp)

Some of our iOS apps (such as iCMTGIS II, iGPSGIS II and Utility Data Collection) also provide a Map option under the Background Map function. You can use this option to load the image of an existing job map (*.pmp) to use as the background map for another job. The Utility Data Collection app can output the .pbm map to PDF.

4) Portable CMT Basemap (*.pbm)
The CMT Basemaps are only available for the counties in the USA. You will need to use the optional CMT PC mapping software to load the CMT Basemaps and prepare the .pbm registered images. iCMTGIS II, iGPSGIS II and Utility Data Collection provide the ability to display the .pbm maps. Utility Data Collection can output the .pbm map to PDF.
