I’m looking for a way of building a polygon around a primary GPS point, in real-time for a specific type of health intervention.
Ideally, I would have:
(1) a primary point
(2) 4 points making a diamond shape around the primary point.
The data collector would take the primary point using the geopoint function
The data collector word use the geoline function to draw 4 lines from the primary point that extend to 100 metres in 4 different directions (producing 4 lines from the primary point to 4 different new points)
An internal calculation can then make a polygon around the primary point, based on the 4 points. Voila.
I think I can do all of this, but the issue is for the data collector to be able to visualize the distance in real-time on a map. Can a configuration be done in OSM to produce the following labeling of the line on the map with a distance? (see picture for an example).
Welcome back to the community, @rratnaya! I don’t think this is possible, but I am leaving this open to the community to chime in the discussion.
However, at the same time, I am also sharing the xlsform to demonstrate how distance can be calculated in KoBoToolbox using geopoint and geotrace. Maybe it should be helpful to those, who wish to measure distance in their project(s).
