“Buffer - Distance - Area” is a handy universal app for iPAD, iPhone and iPod touch that lets you easily digitize a Line Feature or an Area Feature, view its length or area, and create buffer zones around it. The line segments of the digitized Feature will be labeled with angles and distances. You may specify the distance unit and choose between Azimuth and Bearing for displaying angles. You may create one or more buffer zones, such as for calculating the area to mow inside and outside a fence around a large complex, or for figuring the tax credit for an unfarmed riparian zone. You may also delineate sub-areas of interest to view their areas. You may save and email the buffer file (*.bfr), or output the drawing and coordinates as a PDF file. If your device has GPS capability, you may pick the GPS location as a node for your Line or Area Feature. Please note: Location data depends on the GPS receiver used. Continued use of GPS running in the background can dramatically decrease battery life. This app will let you easily toggle the built-in GPS on or off. It comes with a built-in help file.
