2 Chuvieco and Huete (2009): Fundamentals of Satellite Remote Sensing, Taylor and Francis RS and GIS 1. Managing of geographic information. 2. Relationships between the two techniques:  GIS contributions to RS.  RS contributions to GIS. 3. Procedures to link RS and GIS:  Updating vectors.  Exporting interval-scale variables.  Exporting classified data.
