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. </p> <p>PostGIS allows to very simply load and query geospatial data from the database for representational purposes. </p> <p>Refer my original blog <a href="https://bit.ly/3qEO5LI">here</a> 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. </p> postgis geospatial data postgres Antara Datta Wed, 02 Jun 2021 17:33:12 +0000 https://dev.to/antaradatta3/understanding-geospatial-data-ohf https://dev.to/antaradatta3/understanding-geospatial-data-ohf <h2> What is geospatial data? </h2> <p>When a set of data encompasses geographic location as the reference component, it is referenced to as geospatial data. It represents some information about a specific location or over a range of a given location. The location can range from a specific point to a larger area. Oftentimes, GIS and geospatial data are interchangeably used. </p> <blockquote> <p>GIS is a programmatic system that creates, stores and analyses geospatial data. </p> </blockquote> <p>View the original blog here <a href="https://www.nitorinfotech.com/blog/understanding-geospatial-data/">Understanding Geospatial Data</a></p> <p>To know more about, how geospatial data can be used using postgis please take a gander at the follow up article: <a href="https://dev.to/antaradatta3/getting-started-with-postgis-57pm">Getting started with PostGIS.</a></p> geospatial vector crs raster
