The document presents a lecture by Rehana Jamal on the basics of Remote Sensing (RS) and Geographic Information Systems (GIS). RS is defined as the science of acquiring information from a distance without physical contact, while GIS is a system for collecting, storing, and analyzing spatial data related to the Earth's surface. Key definitions of GIS highlight its role in data integration and spatial analysis.

Definitions of GIS
“GIS is a computer system that can hold and use data describing places
on the Earth’s surface.” Rhind(1989)
“A set of tools for collecting, storing, retrieval at will, transforming, and
displaying spatial data from the real world for a particular set of
purposes”. Burrough(1986)
“A system for capturing , storing, checking, integrating, manipulating,
analyzing and displaying data which are spatially referenced to the
Earth”
