I use select_one_from_file with geojson file and it's beautiful. But i would like to declare / create a new point (not present in geojson file) with geopoint and in the same time have a look for the geojsonfile point for a relative placement. It's look like have a layer with geojson informations in the geopoint / placement-map process. I don't know if there is a way to do this but this feature seems interesting to me
I think what you can try is Entities and Datasets in ODK the sample presented in the video shows how to add new points visible in
select_one_from_file via ODK Collect.
This might be not a perfect solution for you but it's probably the only one.
This is very closely connected to Mapping within a repeat group : show already drawn objects on the geowidget map. We're thinking about how to address both, perhaps also intersecting with Provide a way to get mbtiles to Collect without having to connect to a computer.
@Grzesiek2010 Unfortunately I don't think the current Entities functionality helps with this. There need to be a way to show entities on a map where a point can also be selected. I think coming up with a general way to set a reference layer from mbtiles, geojson, CSV or nodeset would be really useful. We also will probably at some point want to consider open selects from map.
Thank you LN and Grzesiek2010. I'll see what i can do with Entities and wait for new version with more possibilities. Select one from file with geojson is young possibilities and the future complete this.
