PostGIS: The Power of Spatial Databases

Build the Spatial Database Behind Modern GIS

Store. Query. Analyze. Power.

PostgreSQL is a powerful open-source database, and PostGIS extends it with advanced spatial capabilities for storing, querying, analyzing and managing geospatial data.

This hands-on training takes participants from the fundamentals of PostgreSQL and spatial databases to practical PostGIS-based spatial analysis and application integration.

You will learn how to build a spatial database that can serve as the foundation for GIS, Web GIS, spatial analytics and enterprise geospatial applications.

From Data to Spatial Intelligence

Learn how to transform raw spatial datasets into a powerful, queryable spatial database.

Spatial Data → PostgreSQL/PostGIS → Spatial SQL → Analysis → Web GIS

The course focuses on practical workflows rather than database concepts alone, using real-world geospatial datasets and hands-on exercises.

Learn by Building

Create Your Own Spatial Database

Participants will work with real-world datasets and build a functional spatial database from the ground up.

During the hands-on sessions, you will:

1. Create a PostgreSQL database and enable PostGIS
2. Create spatial tables and define geometry types
3. Load real-world geospatial datasets
4. Work with different Coordinate Reference Systems
5. Write spatial SQL queries
6. Perform spatial relationships and spatial joins
7. Conduct buffer and proximity analysis
8. Perform intersection and overlay operations
9. Create and use spatial indexes
10. Optimize spatial queries
11. Prepare PostGIS data for GeoServer
12. Connect the spatial database to a Web GIS workflow

Real-World Spatial Analysis

The practical exercises will demonstrate how PostGIS can answer common GIS questions, such as:

Which properties are within 500 metres of a road?

Which infrastructure assets fall inside a particular administrative boundary?

Which features overlap with a flood-affected area?

What is the nearest facility to each location?

How much area does each land-use category occupy?

These exercises help participants understand how spatial SQL can replace repetitive desktop GIS workflows with powerful, database-driven analysis.
