I am interested in performing Big Data Geospatial analysis on Apache Spark. My data is stored in Azure data lake, and I am restricted to use Azure Databricks. Is there anyway to download Geomesa on Databrick? Moreover, I would like to use the python api; what should I do?

Any help is much appreciated!!

You can install GeoMesa Library directly into your Databricks cluster.

1) Select the Libraries option then a new window will open.

enter image description here

2) Select the maven option and click on 'search packages' option next images

3) Search the required library and select the library/jar version and choose the 'select' option.
Thats it. search the jar/library in maven repository

After the installation of the library/jar, restart your cluster. Now import the required classes in your Databricks notebook.
I hope it helps. Happy Coding..

As a starting point, without knowing any more details, you should be able to use the GeoMesa filesystem data store against files stored in WASB.

CCRi (backers of geomesa) has generated spark runtime friendly build. A shaded fat jar for GeoMesa (current version is 3.3.0) is available at the maven coordinates org.locationtech.geomesa:geomesa-gt-spark-runtime_2.12:3.3.0 which for Databricks.​ ​S​ince it is shaded, users can add maven exclusions to get it to cleanly install which would be "jline:*,org.geotools:*" added in Databricks library UI without quotes​.

Running GeoMesa within Databricks is not straightforward:

  • GeoMesa’s artifacts are published on Maven Central, but require dependencies that are only available on third-party repositories, which is cumbersome given Databricks’ library import mechanism.
  • GeoMesa conflicts with an older version of the scalalogging library present in the Databricks runtime (the infamous JAR Hell problem).

Reference: Use GeoMesa in Databricks

Hope this helps.
