Does the app “Area – Distance” allow a person to walk a perimeter to determine the area of a field?

The Area – Distance app is mainly for digitizing a line or an area on the displayed Apple Map then determining the distance or area, respectively. If you are using an iPhone or an iPad with built-in or external GPS, then you could use the Pick GPS function to drop nodes manually as you walk a perimeter to create the Area Feature.

However, the proper way to map a field using GPS is to use the Data Collection function provided by iGPS GIS II for iPhone, iCMTGIS II for iPad or Utility Data Collection for iPad. Using the Data Collection function, you can specify how often to drop a node (default is once a second) and you can also record one or more descriptions for the Area Feature. The app will do the area delineation for you as you walk the perimeter. If the area is a polygon with straight sides, the app also provides an option to record just the corner points to create the Area Feature.

iCMTGIS II is now available
