We always like a good challenge. More than once in the last few weeks we have been asked if it is possible to auto generate features – points, lines, polygons – on a mobile device using GPS. So store the path followed using the built in mobile GPS. Then generate a feature from this data. We put our thinking caps on and came up the application you see in the video below
The demo shows the app running on an Android tablet in offline mode. This could just as easily have been an iPad; since we built the app using Mobile Flex which can run on either platform. We first generated a tile package in ArcMap, this forms the offline basemap and is stored on the tablet. Checkboxes in the top left header allow users to select either polygon or line as the final generated feature. Start and stop buttons initiate data collection, and generate the final feature respectively. In the demo we drove around a block; starting and finishing at the same point, so we chose to generate a polygon.
