The course aims at familiarizing students with geo spatial data and at introducing them in Geographic Information Systems and Remote Sensing technologies. By the end of this course the students will be able to:
- Distinguish the concepts of analogue and digital image and calculate the digital image statistical parameters.
- Distinguish the geographical data as vectors and rasters and information as spatial and non- spatial.
- Understand the interactions of electromagnetic radiation with materials and atmosphere.
- Study maps of Greece and to recognize the projection systems.
- Recognize the most common satellite images and to digitally process them.
- Use geographic and geological data in GIS environment, to process it and produce maps.
By the end of this course the student will, furthermore, have developed the following skills:
- Ability to demonstrate knowledge and understanding of basic concepts, about GIS and RS.
- Importing, storing, processing, managing satellite data with the use of specialized software.
- Enhancing the quality of images, creating colored composites and interpreting them.
- Implementing geometric correction, georeferencing and digitization of satellite images.
- Importing, storing, processing, managing geographic and geological data in GIS environment.
- Creation of DEM out of digitized contour lines and production of topographic and elevation profiles.
- Creating maps with the combined use of Geographic Information Systems and Remote Sensing data.
