About course

Description

Did you know that databases can store geographical data? With the help of spatial extensions, a database can store the locations of stores, ATMs, hotels, streets, districts, and other points of interest. Moreover, you can use SQL queries to process this information.

In this course, you’ll learn about PostGIS, a spatial extension of the PostgreSQL database. You will learn how PostGIS stores geographical data and how its basic geographical functions can be used in simple and complex SQL queries.

To make your learning process more interesting, we'll be working with both real and not-so-real places in San Francisco and the United States. Additionally, we’ve prepared a special surprise—some exercises will even let you see the results of your queries drawn on a real world map!
