Hey surveyer,

is it possible to display administrative borders/areas on the osm map and let people choose a polygon by highlighting it?

There is that function to display a map and place a symbol on it (category short text answer), the result is geolocation by latitude/longitude. But I would like to show up several polygons and save that one in database, which will be selected by user.

I have a shapefile (could be converted to other formats) with administrative borders.

Photomontage attached for clarity.

What I have done so far:

- converted shapefile with a QGIS plugin to a leaflet JavaScript.
- replaced folder in third_party/leaflet with above content

But map view in survey has not changed although original files of leaflet are replaced. The map itself works when running as dedicated html page.
I don't have a clue, how to make a selection in leaflet permanent and transfer the result to limesurvey database.


Any suggestions?

Hi Sansibar!

I can unfortunately not help on this, but just to mention it would indeed be very welcomed!
We also collect most of our data against admin units in various countries

Please let me know if you work something out,

If the map is "restricted" , maybe it's more easy to use a picture with

See demonstration.sondages.pro/21764

And with imagemap : github.com/stowball/jQuery-rwdImageMaps or an example with a multiple choice question type : www.outsharked.com/imagemapster/examples/usa.html

Following up on Denis' comment about ImageMapster, here is an online tool to create the image maps (area coordinates) - imagemap-generator.dariodomi.de/

Or follow : www.gimp.org/tutorials/Image_Map/

@tpartner : we don't have a workaround for image map in manual ? (if not i must put one ).
For the javascript : i use id on the map, not link.
