There is increased and wider use being made of remotely sensed data from terrestrial and aerial photogrammetry, laser scanners and satellite sensed data to gather information for geographic information systems. Computer and electronic technology advances are continually increasing the availability, variety and usefulness of this photogrammetric and satellite sensed data, increasing its importance within the spatial information industry. It is necessary for the spatial science professional to be aware of the methods of acquisition of these data forms, their accuracies and precision, their uses and the relative economics compared to other spatial science techniques.

This course will enable students to extract, interpret and evaluate data from aerial photographs (including images captured by UAVs), terrestrial photographs and laser scanned images. This data will be presented and related to the environment or integrated with other data forms for direct application or information system storage. This course will also develop the student's understanding of the physical basis and properties of remotely sensed data. During the investigation of applications of this satellite sensed data, students will develop basic skills and knowledge in extracting, manipulating, interpreting, analysing and presenting this data.

On completion of this course, students should be able to:

1. explain the basic principles, theory and accuracy of various aerial terrestrial and close-range photogrammetric methods;
2. design of photogrammetric surveys;
3. compare the methodologies and techniques of using digital photogrammetric equipment, to extract information from photographs;
4. appraise the application of photogrammetric methods to topographic mapping, engineering projects and information gathering for geographic information systems;
5. describe the basic principles of Unmanned Aerial Vehicle (UAVs), types of UAVs, their applications and how to plan UAV operations
6. discuss how image processing is done to create data products such as digital point clouds, orthophotos and Digital Elevation Models (DEM).
7. illustrate the accuracies and application of laser imaging;
8. describe the basic principles of remote sensing and possible applications;
9. describe the physical basis of remote sensing; these include spectral, temporal, spatial and resolution properties; the spectrum and its radiation and reflectance properties; and image properties.
