Lesson overview

In this week’s lesson we will introduce you a spatial data model (geometric objects) and some basics of how spatial data can be manipulated in pure Python.

  1. Geometric Objects - Spatial Data Model

    • Overview of Geometric Objects and Shapely -module

    • Point -object

    • LineString -object

    • Polygon -object

    • Geometry collections (optional)

  2. Exercise 1: Working with geometric objects

Learning goals

After this week you should:

  • have an idea of what kind of tools are available for doing GIS in Python

  • know how to install Python packages using conda

  • know what kind of geometric objects are available

  • know how to create different kind of geometries using Shapely

  • know how to read coordinates from a file and create Points based on those
