10. Image processing exercise using LEOWorks
1About LEOWorks
LEOWorks is an image processing software for educational use. It can be applied to display, analyze, enhance and interpret images from Earth Observation satellites. LEOWorks is available free of charge (see right of page). An extensive tutorial is available.
We will use LEOWorks here to demonstrate basic features of Earth Observation.
Data
The data covering the Alban Hills are from the Landsat 7 satellite system. Images from the whole of Europe can be downloaded from the Eduspace Image Catalogue.
We will use Band 1, Band 2, Band 3 and Band 4.
