1. What is the general goal of the feature?
To be able to edit existing records that have geotrace data by selecting them on a map. Currently it is possible to visualise existing geopoints (e.g. Visualize on the fly in the mobile phone the data collected with ODK on a map) as long as they are not in repeat groups. It would be great to do the same with geotraces and geoshapes.
2. What are some example use cases for this feature?
When collecting 'linear' data it would be useful to be able to see that visualised on the 'fill blank form' map to check that there is no overlap / duplication of coverage.
This could be useful for longitudinal studies, where the geotrace has been previously collected and 'blank forms' could be pre-loaded to a device. This could then become a monitoring tool (which is my main interest).
In my wildest dreams (related to ODK Collect, not that I dream about an app, you understand!), I would like to be able to select a geotrace / or geoshape on a map to create a new record associated with that trace (similar to B) almost like a 'visual select_one' widget - so that it is not necessary to create the trace or shape in the field but 'copy' it from a predefined list - currently I do this by creating a geopoint over a base layer (mbtiles), then match up the point and the line / shape on the GIS, which is a bit tedious with lots of data points.
3. What can you contribute to making this feature a reality?
Anyone who's used this forum knows how good I am at breaking stuff... happy to test
I'm hoping that the functionality might be similar to that used for on-the-fly visualisation, so it could 'borrow' from that? Maybe...
