A geographic information system (gis) is a computer based tool for mapping and analyzing things that exist and events that happen on earth. gis technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps.
Gis Revision Pdf Geographic Information System Computing 1 introduction to geographic information system every decision that we take today is largely driven by location and has spatial connotation directly or indirectly. in this unit we will learn about geographic information system (gis) –a modern day spatial decision making system. gis has come a long way from digital mapping to decision making , invoking simulations , creating networks. A geographical information system is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. in general, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. gis applications are tools that allow users to create interactive queries (user created searches),. Gis applications gis applications allow users to create interactive queries (user created searches), analyze spatial information, edit data in maps, and present the results of all these operations. geographic information science giss (definition) is the science underlying geographic concepts, applications, and systems. Introduction to gis nature of gis – geographic information systems (gis) are computer based systems designed to capture, store, manipulate, analyze, and display spatial (geographic) data. gis can be used to represent, analyze, and visualize the relationships, patterns, and trends in data that have a geographic or spatial component.

This document provides an introduction to geographic information systems (gis) through two lecture summaries. the first lecture defines gis and discusses the key stages of working with geographic data: data preparation, analysis, and presentation. it also distinguishes between data, which can be operated on by computers, and information, which requires human interpretation. the second lecture. This course introduces the basic concepts of geographic information systems (gis). it will present fundamental geographic and cartographic principles that are the foundation of gis and current state of the art information technology tools that bring gis to users’ desktops.
