This document provides an overview of geographic information systems (GIS). It discusses that GIS combines maps with layered information about geographic features. The key components of GIS are computer systems, GIS software, procedures, data, and end users. GIS has various applications in technical areas like water resource management, environment, agriculture, as well as commercial, social, and administrative uses. GIS offers benefits over traditional paper maps and other software by allowing more efficient analysis of spatial and attribute data to support improved decision making.

- 2. CONTENT :- INTRODUCTION CLASSIFICATION OF GIS THE FOUR M’S OF GIS KEY COMPONENT OF GIS FUNCTION OF GIS DATA FOR PREPARATION OF MAPS
- 3. iNTRODUCTION GIS is the combination of maps of geographic area and information of every kind. i.e. Technical ,Administrative ,Social ,Political for each and every feature of earth surface. GIS =Geographic +Information +System. GIS is the intelligent map which will give you much more information of roads, villages, etc. which is not available with traditional papers maps
- 4. Classification Of GIS:- Special purpose GIS General GIS 2D GIS, 3D GIS 4D GIS Web GIS Multimedia GIS Virtual GIS
- 5. The for M’s of GIS Measurement > Spatial data, attribute data Monitoring > Measuring, changing parameters of data Mapping > Intelligent maps more than real world Modeling > Presentation of data in charts, tables or 3D models virtual reality model.
- 6. Key Components Of GIS:- Computer system GIS Software Procedure to operate GIS Data and Information End Users of GIS
- 7. Function Of GIS:- Objectives Of GIS:- To collect , analyse and manipulate spatial data To produce maps and other products in standardized formats for different uses. To supply information In useful formats for logical decision making for planners. To support research activities using spatial as well as non-spatial data.
- 8. Importance of GIS:- Technical Application:- Water resources Management Environment Agriculture Forestry Military Transportation Urban Planning Civic Taxation Regional Planning Telecommunication Network
- 9. Commercial Application:- To locate site of exploration To locate business centre for marketing To locate areas of raw material To assess regions of demand-supply gap for particular commodity.
- 10. Social Application To locate under developed areas Prepare development plante Defence Application Military Intelligence Naval operation Administrative Application Government department Law and order Land Acquisition Disaster Managent
- 11. Advantages of GIS Traditional paper maps DBMS software Computer aided design and drawing software (CADD) Automated mapping Facility management software
- 12. BANEFITS OF GIS TANGIBLE BANEFITS Improvement of efficiency as more output by same staff Increase in income due to increase in production and services Intangible benefits Better service to public More logical and quick decision making
- 13. DATA BASE FOR PREPARATION OF MAPS SPATIAL DATA also known as location data. This data is in form of coordinates latitude, longitude, elevation and time of data recording Attribute data This is in form of other information of feature like name , size , age , characteristics.
