Hello Hello kind humans,
Am in a rather tricky situation. I need to collect multiple points to map an area, but the personnel that are filling in the forms need to be able to do so COMPLETELY OFFLINE (they only get less than bite sized data bundles to download the form with and later send the results). I tried geotrace and geoshape with this, but i can't get around the blank map area displayed AND i need the points to be specifically collected by the app, and not selected by the client. So i resorted to using a repeat_group and GeoPoint, then doing the map drawing and calculations waaaaay later. This has worked well*-ish* since August.
Now the problem: i need to calculate and display the acreage of the mapped area while the form is still being filled. I've been beating around concatenating the geopoints saved and then passing them onto area().
Is there an inbuilt way to use area() with geopoint? is there a workaround someone has figured that could make this work? I would gladly appreciate any input.
