Supervised Classification for Land Use / Land Cover Mapping
Description: This module explores the process of identifying and categorizing land cover types in a satellite image using a computer algorithm calibrated upon a large base of pre-defined training data. This is followed by an investigation of various accuracy assessments associated with this classification method.

Unsupervised Classification for Land Use / Land Cover Mapping
Description: This module explores the process of identifying and categorizing land cover types in a satellite image using an image clustering algorithm that requires with limited human input. In addition, an investigation of various accuracy assessments associated with this classification method is provided.

Geometric Rectification
Description: This module covers the steps involved in correcting the planimetric positioning of features within satellite imagery as a necessary pre-processing step for later analysis. Topics covered include image-to-map rectification, image-to-image rectification, ground control points, and interpolation methods.
Structure-from-Motion (SfM) and Multi-Stereo-View (MSV) for 3D Terrain Modeling
Description: This module surveys the practice of applying the SFM and MSV techniques to process multiple aerial photographs into an orthomosaic, which can be subsequently used as a map or used to create a three dimensional surface model. Topics covered include stereo vision, relief displacement, aerial triangulation, and SfM-MVS.
AQUARIUS Time Series Software
Description: This module explores the use of the AQUARIUS software to model changes in hydrological parameters over time. Topics covered include types and components of a hydrological time series, data correction practices, and data analysis and statistics.
HEC-GeoRAS for Floodplain Inundation Mapping Using
Description: This module covers aspects of hydrodynamic modelling, including the process underlying the mapping of floodplain inundation due to peak flows. To do this it focusses on the use of the GIS extension HEC-GeoRAS (Hydrologic Engineering Center- River Analysis System, developed by US Army Corps of Engineers).
