ELK and dump1090

Just wondering if anybody here has played already with Elasticsearch - Logstash - Kibana to visualize data from dump1090.
I’ve been trying to visualize positions on a heatmap, but so far didn’t manage to get ES to recognize the data from dump1090 as geo_point.
I’ll try again in some days… Now I just deleted my VM out of frustration :slight_smile:
