We are pulling data from servicenow using logstash http poller. The rest api which I am using has a field call location, which is a location name(chennai, India) I doesnot have latitude and longitude field.
We got to know servicenow maintains location information in a different table...so we have ingested data from that table into elasticsearch now I have two index
one without latitude and longitude information.
Two with latitude and longitude information
Now my question is how do I merge these two index to get the lat & long and create map visualization.
Or is there any other way to get the lat & long get attached with the document.
Any advice please
