Basics of Remote Sensing GIS & GNSS 

About 

The course includes principles of GIS technology with an overview of GIS, Geographic Phenomena, Data Inputting and Editing in GIS, GIS Data Models, GIS System Architecture, Geographic Data Standards and Policies, Topology and Spatial Relationship, Spatial Data Analysis, Spatial Data Quality, Spatial Data Errors, Map Projection and Advanced Geospatial Modeling. The free and open source software will be used as a platform for demonstrations and development.

The participants will be appraised of the technological principles of GNSS with focus on GNSS receivers, GNSS data processing methods, errors and accuracy, Satellites based Augmentation systems which includes GPS Aided and GEO Augmented Navigation or GAGAN. The Indian Regional Navigation Satellite System (IRNSS) or Navigation with Indian Constellation (NaVic) will be discussed in detail. The GPS signal characteristics, Data formats (broadcast, precise ephemeris) DGPS demonstration, Advance GNSS processing and Mobile Mapping will also be discussed during the course.
