I am currently using the the jdbc river plugin to populate data into elasticsearch, and in my relational database there are two columns with double number attribute called latitude and longitude. I have combined these two as a geoip.location attribute so that I can use in bettermap. The geoip.location is a string showing like "lon,lat", for example "95.23,13.54".
However, when I add the bettermap panel with this attribute, the map is not loading at all. The strange thing is that if I put geo.locaotin in both "field" and tooltip, the bettermap start to show, but the location is wrong. It looks like it is considering the geo point as lat,lat instead of lat,lon.
Usually you have to explicitly map your field to be of type geo_point. Than there are multiple formats that you can provided your data in. More information about the mapping is here:
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html#mapping-geo-point-type
Beware when providing the point as a string, you have to provide it as: lat,lon.
I would first check my mapping, than insert a document myself and finally check again with the river.
