Shapefiles for Chile shows up in North America

“We update de FORESTER GPS GIS II, on iPad from version 1.0.1 to 1.0.2 and we are having issues with the coordinate system when importing a shape file.The shape appears in North América and we are from Chile. We use UTM with Datum WGS84. Is there any suggestion on what can we do. I try this in two different devices with the new version and both have the same problem. When using it in the 1.0.1 version all goes OK.”

Please make sure you have selected the correct UTM Zone.

Please also copy the .prj file for the Shapefiles to the documents folder for Forester GPSGIS II.

What coordinate system do the Shapefiles use? If they are based on WGS 84 LLA, then try setting the Forester GPSGIS II to that coordinate system before importing the Shapefiles. After importing the Shapefiles, then change the coordinate system to UTM WGS84.


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.

Deed Calls, Grid and Stakeout functionality for Windows

“We bought your DeedCalls Grid Stakeout software for my IPad. Beautiful, simple and functional program. My question: can you have it for Windows?”

We have a PC-GIS X software program for use on Windows XP, Windows 7, Windows 8 and Windows 10 that provides the Create Grid, Create Deed Calls and Navigation functions. Many of our customers use it to complete a map and print it to a printer or to a PDF or JPG file.

Our PC-MAPPER software program provides Create Grid, Create Deed Calls as well as GPS data collection and stakeout functionality. It is ideal for use on a Windows tablet PC, both in the field and in the office.

If you would like to try the PC-GIS DEMO program on your PC, please log on to Select “Downloads and Updates” then click on the PC-GIS DEMO link. The password for downloading and installing the demo program is:



Please log onto your desk-top computer as the administrator with full rights, and make sure there are no firewalls or any antivirus or anti-spyware programs that may interfere with the software installation. Should the installation stall for any reason, please try installing the software in Windows SAFE mode.

Context Help is provided for most functions. Under the Help icon in the PC-GIS DEMO program is a full on-line manual.

The DEMO program provides many active functions, and will let you import Shapefiles, but it will not let you export or save the data. It will let you create a grid over an Area Feature. The DEMO program does not provide the Deed Calls functionality, and some of the functions are disabled.

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.”
