If you have worked with geospatial data, you might want to harness the power of PostGIS. It is an extension of PostgreSQL which adds spatial ability to your database. Reading, analyzing and processing geospatial files like .shp, .tif etc requires special tools. However, doing SQL operations to achieve the same makes it more consistent for developers.

PostGIS allows to very simply load and query geospatial data from the database for representational purposes.

Refer my original blog here to understand the entire installation process for Windows and Linux and how you can set up PostGIS. Additionally, also learn how you can load and query data in a step-by-step illustration.
