I’m using the apps for a DIY survey of some land I own …, and to position the proposed location of a building on a site plan.

Using the built-in GPS of your iPhone and the iGPSGIS II app, you can get a rough boundary survey done. If you have the deed description of the property and are able to determine the point of beginning, you could enter it into the Deed Calls & Stakeout app. Then you can position the proposed location of the building.

Please keep in mind that the iPhone does not provide good position accuracy. Your DIY survey can serve as a guide for planning but cannot replace a professional survey. For better accuracies, some of our GIS customers use a compatible Bluetooth GPS receiver. Still, the 1-3 m accuracy provided by these consumer-grade GPS receivers is inadequate for professional survey work.

We wish you success in your project. Please let us know if you have any questions about using our apps.

Customer’s reply: “Thanks. I will be using the new Bad Elf Surveyor so accuracy shouldn’t be an issue for my modest aims.”
