Do I need cellular data for the app to work?

We received this question regarding the Deed Calls & Stakeout app, but the answer applies to our other apps as well.

The GPS data collection functions and most of the other functions will work without wi-fi and cellular data.

Some of our apps, like Forester GPS GIS III, Farming GPS GIS III, iCMTGIS III and iCMTGIS PRO will let you load a geo-referenced *.tif map and use it off-line.

Most of our apps provide a Map function to get and display the Map from Apple via wi-fi connection. However, you can cache the Map to use out there where no wi-fi is available. This means that you can call up the Map and display the area in which you will be working, turn off wi-fi then go out in the field. You will be able to view the Map while working with your app. As long as you do not play with the Map function while you are out there (such as switching from Show Satellite to Show Hybrid) or close Map, the background map should remain available.


Any Android apps?

An SXBlue dealer wrote:”I am a MAC user, but really prefer Android as a mobile OS. Got a lot more Android interest in the last 12 months than I do iOS interest.”

Yes, we have also received many inquiries about Android apps. However, at this time we do not have plans to develop apps on yet another platform. Currently, we have software for Windows, Windows Mobile/ Embedded Handheld 6.5 and iOS.

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.


On-screen keyboard issue using iGPSGIS II on iPhone 7 running iOS 11

“I think this started since updating to the latest operating system on iPhone. When trying to type new topic name or job name the top row of the keyboard is not responsive. Any ideas what is going on? The top row looks a little odd like something is behind it?”

Here are a couple links to information that may be helpful.

User’s reply:
“Going into settings – general and turning the predictive option off fixed it.”

iOS 11 compatibility and saving data files

Some GPS/GNSS receivers compatible with iPad and iPhone devices

Recently Geneq Inc. announced their new SXBlue Platinum GNSS receiver.

As you know, the accuracy of the work performed using an iOS GPS/GIS app depends on the GPS receiver used. The assisted GPS provided by the iOS devices are not adequate for serious work that are based on accurate locations. External GPS receivers with much better precision abound, but only a limited number of them are compatible with the iOS devices. Following are links to information on some of the external Bluetooth GPS/GNSS receivers that can work with iPad and iPhone devices. Not sureprisingly, higher precision equates to a higher price tag.
