OBJECTIVES:
• Expose the students with concepts of cartography as major components of input and output related to cartography.
• To provide exposure to data models and data structures in GIS and to introduce various Raster and Vector Analysis capabilities.
• To expose the concept of quality and design of cartographic outputs in open GIS environment.
