Lecture

Geometric Spatial Queries

Description

This lecture covers the use of the built-in query tool in QGIS to select spatial objects based on conditional SQL-like queries. It also explores how SQL functions can be used in databases like SpatiaLite and PostGIS to extract properties and features of geometries. The lecture delves into functions for selecting geometric objects, extracting reference system codes, converting formats, retrieving spatial objects graphically, and extracting various characteristics and numerical features of spatial objects.
