i am working on a draft for an online-based survey. I would like to enable the participants of the survey to draw polygons, lines and points (several) on a basemap (e.g. google maps) and (extra feature) additionally to comment on these elements. Each element drawn by one participant should be stored.
I am looking for a ready-to-use method/tool to embed it in the survey. Right now, a fully costumized solution is not an option. Unfortunately, i couldn't find a suitable tool yet.
The whole idea is more or less a mental map, an interactive tool to highlight topographic elements on a basemap.
If you know some possible solutions or tools to meet my requirements, i would appreciate any suggestion.
