I am using Drupal 8 and I am trying to display a map of a Geofield field, using Leaflet. This part works as expected when I manually enter coordinates into the Geofield.
But problem comes with the geocoding part : I set up a File field to store a KML file. When the Geofield is told to geocode from the KML file field, each time I create or modify a content, two messages are shown :
- a warning about the fact the file "cannot be geocoded",
- an error saying that Drupal "could not find geo data in file" xxx.
Checking the Drupal log adds an interesting information : there is a php warning with a huge message starting with :
Warning : exif_read_data(test.kml): File not supported in Drupal\geocoder\Geocoder\Provider\File->geocode()
The problem may come from the Geocoder plugin I use for the Geofield geocoding : I can select several plugins in the field management section, all of them apparently dealing with address geocoding, except a "File" plugin. I tried to check only this latter, or all, with the same failing result.
I thought the 'File" Geocoder plugin would be able to deal with KML, GPX... but it may be only for pictures shot containing exif data. Is there a specific plugin for KML files ? And what is the way to make it appear in the Geofield management ?
Anyway, I have tried for hours to find a solution, without any success for any file types (KML, GPX...).
Any help would be greatly appreciated.
