How to Create Spatial and Attribute Indexes in PostGIS with QGIS

This is the last of our new tutorials on spatial and attribute indexing in PostGIS with the help of QGIS. The goal of this tutorial is to give a thorough overview of the process of constructing appropriate indexes to improve the speed of geospatial data manipulation. Regardless of whether you are a GIS expert or have not extensively used the environment of spatial databases, this tutorial will sharpen your claws on how to improve your data management and overall query efficiency.

To start, we will provide a brief on the spatial as well as attribute indexes to understand both forms’ roles in handling large datasets. Finally following this exercise, we shall proceed with actual implementation in QGIS by demonstrating how to established a connection with the PostGIS database, establishing indexes and the way of assessing their efficiency. At the end of this video lesson, you will be assured of the methods discussed above in enhancing the usability of your GIS projects as well as enhancing productivity of analyses. Let's get started!
