Learning outcomesOn successful completion of this module students should be able to:
1. Identify, for particular applications, the most appropriate remote sensing datasets.
2. Independently use remote sensing software (including IDL and eCognition) for the analysis of multispectral, hyperspectral, LIDAR and radar and appropriately select tools for specific applications.
3. Derive digital elevation models from a range of remote sensing data.
4. Undertake field studies to support the interpretation and analysis of remote sensing data.
The course, which is applications focused, will provide students with a sound knowledge for processing and interpreting a range of remote sensing data for various applications. The course will also contain a field visit to the Cambrian Mountains.
Classification of land surfaces using a multi-spectral and hyperspectral data including Compact Airborne Spectrographic Imagery (CASI), HYMAP, Hyperion and Landsat sensor data. The students will be introduced to specialized techniques for extracting information from these sensors, which vary in terms of the spatial, spectral and radiometric resolutions. Processing of hyperspectral data will be in undertaken using IDL ENVI.
The theory of radar remote sensing, including the observation and modeling of microwave interaction with different land surfaces and structures. Applications of AIRSAR, JERS-1, ERS-1/2 SAR data for wetland monitoring, archaeology, biomass and land use/cover change. Techniques for processing and analysing airborne and spaceborne SAR data will be implemented using IDL ENVI.
Generation of digital elevation models (DEMs) using a combination of lidar, stereo aerial photography, ASTER, IKONOS and spaceborne SAR (including interferometry). Students will be introduced to new image processing software for DEM generation and analysis including SOCET SET, Erdas Imagine Orthobase and Gamma SAR processing software. The analysis of the derived DEMs will be undertaken in EAM1620: Advanced Applications in GIS.
Image segmentation and classification using eCognition software will be demonstrated with emphasis placed on the analysis of fine spatial resolution data for vegetation characterization and time-series datasets for monitoring tropical and cover, the dynamics of agricultural land and semi natural vegetation and glacial environments.
Field visit (in conjunction with GIS module) to the Berwyn Mountains, mid Wales, to conduct ground truthing to support the analysis and interpretation of spaceborne SAR and optical data and also airborne hyperspectral data.
