I have certain geographic data that is tied to a date time stamp. Is there a way to somehow show a route map or show a timeline of geographical areas? Like person A went from NYC to Boston to LA to Washington etc?
it depends on how your data is modeled.
If that "route" is represented as a Linestring in a
geo_shape field (https://www.elastic.co/guide/en/elasticsearch/reference/current/geo-shape.html), you can map that trajectory on the Map.
If your data is modeled as individual points (each doc = one point at a location in time), you can plot those points still and filter using the global timefilter of kibana. The "route" would be a sequence of points. This blog might be a good intro for that: https://www.elastic.co/blog/hiking-the-pacific-crest-trail-with-the-elastic-stack-part-3-mission-complete
My situation is the latter however in the blog post he is using google routes, and then he has a tab of GIS on Kibana. Which I dont see, is that a platinum license?
yes. If you download latest Kibana (7.x), you'll find the Maps app. https://www.elastic.co/guide/en/kibana/current/maps.html
Those latter screenshots are taking from that application.
The license for Maps is basic, so it's free.
