Which app to get for mapping forested areas?

“Our main objective is to accurately calculate forested areas using a GPS receiver on iPhone and iPad. We will be driving an atv or truck around the individual areas. The areas will range from roughly 20 – 200 acres, and we are looking to be accurate to the one-hundredth of an acre.”

The GPS that comes with the iOS devices is not quite accurate. You could get a Dual XGPS-A or a Bad Elf GPS receiver and use it with our apps on your iOS devices. These Blue-tooth GPS receivers claim 2 – 5 meters horizontal distance accuracy.

We have a few apps that provide the GPS/GIS data collection functionality that you are looking for.

iCMTGIS II is for use on an Apple iPad with wi-fi capability. It is available from the App Store for $94.99 per license.

iGPSGIS II is for use on an Apple iPhone. It is available from the App Store for $44.99 per license.

iCMTGIS II and iGPSGIS II use the Apple Maps by default. These maps require wi-fi to be active in order to display in the app.

If you also purchase the optional PC-GIS 09 software for use on a PC, then you will be able to load geo-referenced .tif, .jpg, .sid., or .ecw files and convert them to the .pim format for use with iCMTGIS II or iGPSGIS II as background maps.

The feature data recorded with iCMTGIS II and iGPSGIS II can be loaded into PC-GIS 09 for further map enhancement/processing and print-out. PC-GIS 09 is listed at $385 per license, but we can offer you a discount if you purchase the iCMTGIS II or iGPSGIS II app. PC-GIS 09 is easy to use. Many foresters use it for managing their forest map files. If you don’t already have GIS software for your PC, this will be a good investment.

There is also an iCMTGIS III app that can run on both the iPad and the iPhone devices. It is listed at the App Store for $199.99. This app will let you load a GeoTiff as background map without the need for using PC-GIS to convert the map file. Besides the GPS/GIS data collection functions, this app also provides Stakeout functions that will help guide you to destination points or along the perimeter of an existing area. If you are interested in a GIS software program to use on your PC to work further with the data collected using iCMTGIS III, the matching software is the PC-GIS X (same price as PC-GIS 09).

All of the above-mentioned apps can import and export Shapefiles.

Our Forester GPS/GIS III and Farming GPS/GIS III also provide the GPS data collection and Stakeout functions, but these apps can only run on the iPad device.

    Wondering why Forester GPS II or III is not one of the suggested Apps ? Cost ?

      Hi Brian,

      Thank you for your kind comment. I guess you did not read the entire reply. We did mention Forester GPS GIS II/III at the end.
      This group of users have iPad as well as iPhone devices, and they are not particularly interested in the forestry-related calculators. It would be more economical for them to get an app that will work on both devices. Another forester also emailed us recently for app recommendation, and we asked him to look at Forester GPS GIS II/III. πŸ™‚ Happy Holidays!
