Course Description
PostGIS adds GIS spatial types and support to PostgreSQL. It is used by Database and GIS Professionals who need to store and query both the spatial and non-spatial attributes of their data in the same queries. So the data is stored in rows and columns. Because PostGIS is a spatial database, the data also has a geometry column with data in a specific coordinate system defined by spatial reference identifier (SRID).
Course Objectives
- Learn what spatial databases are
- Learn the basics of working with PostGIS, a spatial extension of PostgreSQL
- Learn how geographical data is stored in a database
- Learn about the basic geographical functions available in PostGIS
- Learn how to write SQL queries using geographical functions
Who Should Attend?
- GIS specialists
- Anybody involved in professional work in which spatial information is needed and needs to be put in place.
