The course aims at training students in creation and management of databases and at familiarizing them with advanced digital image processing techniques. Furthermore the course introduces students to spatial data analysis,spatial queries formulation and decision making. By the end of this course the students will be able to:

1. Distinguish RS data based on the wavelength.
2. Use airphoto or satellite stereopairs to create Digital Surface Models.
3. Process thermal, hyperspectral, as well as radar data in a Geographical Information Systems environment and produce maps.+
4. Perform GPS measurements in the field and process them
5. Recognize the most common satellite images and to digitally process them.
6. Create geodata bases and process multilayered information.

By the end of this course the student will, furthermore, have developed the following skills:

1. Ability to demonstrate knowledge and understanding of basic concepts, about GIS and RS.
2. Importing, storing, processing, managing thermal and hyperspectral satellite data with the use of specialized software.
3. Importing, storing, processing, managing radar satellite data with the use of specialized software.
4. Importing, storing, homogenizing, processing, managing geographic and geological data in single geospatial data bases.
5. Creating Digital Surface Models using photogrammetric methods from both aerial and satellite stereo images.
6. Creating maps with the combined use of Geographic Information Systems and Remote Sensing data.
