lucene-geo-gazetteer is a very cool Apache Tika, Apache Lucene, and Apache OpenNLP tool that builds a fast index of geo data built from a large list of all countries' data. It then provides a REST API that we can easily integrate into a flow.

So I have connected this to a NiFi flow for enhancing and enriching Twitter data with Geodata.

Example NiFi Flow To Convert Twitter Locations Into Geo Information

Downloading the Countries' Data and Building the Geo Indexes

Calling the Local Geo Server

Example JSON Data Returned

Let's pull out the fields we want after the split

Let's build a new JSON file of just the fields we like including the new geo ones.

Example JSON Processed
