Using GIS to visualise the impact of physical and human processes on coasts

I can use GIS aerial imagery and webmaps to visualise the impact of physical and human processes on coastal landscapes.

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. GIS uses historical imagery to visualise and analyse how the coastline changes over time. This is called temporal data.
  2. GIS uses historical maps to analyse how the coastline changes using georeferenced older maps.
  3. GIS apps which enable visualisation of temporal data include Esri Wayback and NLS Maps.
  4. GIS apps use historical imagery and historical maps to visualise and measure change such as the rate of coastal erosion.

Keywords

  • Historical imagery - photographs from any time in the past which can be compared with more recent photographs including aerial, satellite or conventional

  • Temporal data - information which is tied to a particular point in time, so that data can be time-enabled (also known as spatiotemporal data)

  • Historical maps - maps from any time in the past which can be compared with more recent maps

  • Georeferenced - information which has been tied to a particular location (geolocated), using an agreed system such as latitude and longitude

Common misconception

Confusion between similar sounding GIS tools in Esri Wayback; Use of 'Measure tools' in NLS Maps.

CfU to clarify learning and procedures e.g. similar sounding GIS tools in Esri Wayback: ‘Toggle Animate Mode’ ‘Toggle Swipe Mode’; careful use of 'Measure distance' tool in NLS Maps along with 'Swipe', ensuring line is perpendicular.

No matter what your level of experience is with GIS, go through all the steps yourself first until you feel confident and fluent. Don't worry if you make a mistake, everybody does, even experienced practitioners!
Teacher tip

Equipment

The lesson will require students to have access to a suitable IT device e.g. laptop. Some tasks would be facilitated by the students using a mouse for more effective and faster control of the cursor.
