Using GIS to analyse river catchments and profiles
I can use GIS to analyse river catchments and profiles.
Lesson details
Key learning points
- The GIS tool 'Trace Downstream' can be used to analyse the course of a river.
- The GIS tool 'Create Watersheds' can be used to analyse the drainage basin (catchment) of a river.
- The GIS tool 'Elevation Profile' can be used to find out if a river's long profile corresponds to a theoretical model.
Keywords
Analysis tools - a range of GIS applications used to support the processing, analysing, and visualising of spatial data
Trace Downstream - a GIS tool which maps the course of a river from a location such as its source to the end of the river
Create Watersheds - a GIS tool which maps the drainage basin or catchment of a river and all of its tributaries
Elevation profile - a GIS tool which visualises changes in height above or below sea level along any transect line such as a river course
Common misconception
Difficulty in remembering meaning and location of icons in ArcGIS Online, e.g. Analysis Tools and Scene Tools.
Frequent reminders and checks for understanding about icon locations and their meanings, e.g. Analysis Tools and Scene Tools.
Equipment
The lesson will require students to have access to a suitable IT device, e.g. laptop and log-ons for ArcGIS Online. Some tasks would be facilitated by using a mouse to control the cursor.
