GIS: Visualising and Analysing coastal erosion

I can visualise and analyse coastal erosion using GIS platforms.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Aerial imagery can be used to visualise coastal erosion using GIS.
  2. Old and new maps can visualise coastal erosion using GIS.
  3. Analysing maps and aerial imagery using GIS can help us explain patterns of coastal erosion.

Keywords

  • Geographic information system - a geographical information system (GIS) is a computer mapping system that captures, and displays geographic data to help understand spatial patterns

  • Visualise - to form a mental or physical image of something, making it easier to understand

  • Analyse - to break things down and identify patterns and relationships

Common misconception

Coastal erosion is likely to be the same in different places along a stretch of coastline.

Coastal erosion varies between different places. It is influenced by human factors, such as whether coastal defences have been installed, and physical factors, such as the rock type.

It is easy to extend this lesson using the same GIS applications and let the pupils complete an enquiry project about coastal erosion the Holderness coast.
