This module deals with the theory and practice of producing and validating digital elevation models and orthoimages from optical aerial and satellite sensors including laser scanning (LiDAR). It reviews fundamental technology with an emphasis on solutions for airborne sensor orientation and covers mapping from other sensors, such as interferometric SAR from space and airborne platforms. The practical application of the technique will be demonstrated through the use of example data sets and through practical work.
The aim of the module is to give students a thorough understanding of the process of point cloud, DEM and orthoimage generation from aerial and satellite imagery, including LiDAR. Students will understand the concepts, principles and process of point cloud, DEM and orthoimage generation and will be able to carry out the procedure for themselves such that they can understand the workflow. They will also be able to assess the quality of the product and understand the nature of the errors which affect the product. The course aims to put these methods into context of other mapping methods and provide an appreciation of the data processing steps needed to produce a variety of different spatial data products. Coursework will be carried out as a group project structured to ensure that students appreciate the need for teamwork and will learn how to produce a project report.
