Introduction to SAR data and Application
This 2 full day hands-on training course is organised by RUS and the Technical University of Denmark / DTU Space.
Objectives
Preliminary Programme
Day 1 – Land cover/ Crop type classification
Morning: During the first morning session, a brief introduction to
satellite remote sensing will be given, with emphasis on the different
information content and complementarity of SAR (Sentinel-1) and optical data
(Sentinel-2). The second session will focus on feature extraction and introduce
different types of classification algorithms (e.g. Bayisian, K-means, Random
forest). Their pros and cons will be presented with special attention to
multi-waveband data and multi-temporal data. Concerning SAR, also the inherent
speckle noise and its influence on classification will be covered.
Afternoon: Hands-on exercise within a RUS environment. In this tutorial, we aim to introduce
Optical (Sentinel-2) and SAR (Sentinel-1) data feature level fusion for land
cover and crop monitoring on a study area in Denmark. We will use a time series
of optical and SAR GRD data to demonstrate how multi-temporal and multi-sensor
approach can increase the accuracy of our classification. Optical data provide
accurate land cover/crop classifications if the cloud free acquisitions time
series is large enough and if the acquisition dates are taken in the suitable
period of the year. However, in study areas with extensive cloud cover, the
number of available optical images could be insufficient for accurate
classification. SAR time series from Sentinel-1 can be used combined with the
optical Sentinel-2 data in these cases to improve the results.
DAY 2 – Sentinel-1 InSAR processing for ground
motion monitoring
Morning: Two theoretical lectures will be given. The first will provide
a top-down introduction to SAR interferometry (InSAR), with emphasis on its
application to the measurement of surface deformation. The working principles,
applicability requirements, and main error sources of InSAR techniques will be
presented starting from examples and covering the relevant theoretical concepts.
The second lecture will address specific properties of the Sentinel-1 SAR
Terrain Observation with Progressive Scans (TOPS) acquisition mode, and discuss
the processing steps required to carry out InSAR deformation measurements.
Equipment
Attendees must bring their own laptop and will be provided with access to the RUS platform Virtual Machine.
