Can’t hear sound from iCMTGIS III app on iPhone 6

“When I turn GPS on in my app, I don’t hear any beeps. My iPhone 6 works fine. Volume is turned up. The Navigation Beep and Featuring Beep show checked.”

Please check the Ring/Silent switch on the left side of your iPhone 6. It needs to be moved toward the display side. For additional information, please see the article at


Is the iPhone GPS accurate?

“I am looking at purchasing your Deed Calls – Grid – Stakeout app for my iPhone to help me find my property boundary stakes from an old survey. Does it use the GPS off the iPhone? Is that typically accurate enough to get started? Or do you recommend some other GPS devise to use. If so, any suggestions that are reasonable priced?”

The app can use the GPS off the iPhone. It is not quite accurate, probably around 10 meters. Many users purchase the Dual XGPS 150-A or the Bad Elf GPS to get 2 – 5 m accuracy. These are relatively inexpensive. So, if you think you will be able to find a stake within an area of 30 ft x 30 ft, then use your iPhone GPS. If you only want to search within an area of 15 ft x 15 ft, then get the Dual or Bad Elf receiver. You could try it first using just the iPhone and see how it goes.


How to change the symbol and color for all the points of a Topic in iCMTGIS PRO

“Is there a way to change the point color and style of a topic that has lots of point or do you have to change them one by one?”

Please turn on Topic View. If you are running iCMTGIS PRO on an iPad, tap on the second tool icon from the right side at the top. On an iPhone, that would be the last icon on the right side.

Double-click on the symbol by the Topic Name. The new symbol and color you choose will be applied to all the points except for the ones you have previously changed by hand.


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.


Emailed Shapefiles not up to date?

“Now I have been working with the CMTGIS PRO app practically for over ten days. I have been collecting and measuring and I have been really satisfied. Today I have got an issue that I can not solve, hope you can help me. . . . I created a job for the project with that contains a handful of topics that I have been using all time. In the job I have created one topic for stored points, and i have used three topics for lines. The pre defined ‘Fence’, ‘Measure distance’ and one called ‘retur 1’. After I have been working 4 days I emailed the shapes (except for fence) files to use them in qgis, everything worked fine! After the last three days of work I have tried to email all four shape files, but I can not find the shape file ‘Fence’ anywhere but in the job. And, the three shape files I could find and send by email have not got any of the new features I have created the three last days???”

Later, the user found that by exporting the Features as Shapefiles in a Group, he was able to email the ‘Fence’ Topic, and the other three Topics had updated information in them.

For the user’s convenience iCMTGIS PRO lets the user export the Shapefiles for the Topics in a Job individually or in a Group. However, here the issue is that the Shapefiles need to be exported before they can be emailed. Therefore, if you have added new Features to a Job, please export them to Shapefiles before sending those Shapefiles out via email.


Using an iPhone or iPad app to change the shape of an area

“After I add an Area using the GPS pick function, I want to be able to add a few nodes to be able to make the shape exactly how I want it. Is this possible?”

Which app are you using?

iCMTGIS PRO and iCMTGIS III provide the Insert Node and Mode Node functions.

A number of our apps, such as the iCMTGIS II app, have the Move Node function.

You could add Point Features at the positions of the additional nodes then use the Add Area manually function and tap on all the nodes that form the exact polygon that you want. Then you can delete the original shape.

User’s reply:
“Thanks! It just says Stakeout iCMT 1.0.4 in the About info. I just added another area manually over the existing one, extending out where I wanted it, then deleted the original as you suggested. That worked fine.”
