Lesson 8. Monitoring urban growth

 http://www.learn-eo.org/lessons/l8/

 Satellite observations are a valuable tool for updating urban maps and analysing settlement dynamics - both important for planning sustainable development. The ERS-Envisat SAR archive provides a unique source of data that can be used to track and understanding the dramatic changes in land cover around many large cities over the past 15 years. Using the city of Rome as an example, this lesson demonstrates the use of SAR data to monitor short term and long-term changes. It also explains how interferometric coherence can add valuable information, and shows how optical data may be used to validate results.
