  1. Geographic Information System A Quick Walk-Through

  2. Geospatial Element • Latitude, Longitude, Depth • Points, Lines, Polygons • Co-ordinate Systems • Projections • Visualization Tools • Symbology

  3. Examples of Data • Satellite Imagery • Georeferenced Data • GPS Referenced Data • Boundaries • Geotagged Multimedia Data

  4. Data Visualization • Application • Mapping & Visualization Desktop Software • Arc GIS Desktop • QGIS Desktop • Geo-Media Desktop • Web Map Data Visualization Server Software • Arc GIS Advance Server • Custom Developed Geo-Portal • Apollo Web Map Application

  5. Geo-Portal [ Web Map Server Software] Geoportal is a central application of Geographic Information System, which provides a visual interpretation of data. Geoportal store data in database and then represent it visually in a mapped format. People from different professions use map to communicate. It is not necessary to be a skilled cartographer to create maps. Google map, Bing map, Yahoo map are the best example for web based GIS mapping solution.

  6. What is Geoportal?

  7. What is Geoportal?

  8. Geo-Portal - Objectives • Will put the accent on remote sensing, geospatial-static and in-situ data information and services • Will provide access to information, data and services to better understand, monitor, conserve, predict or simply improve the management of the key society benefit areas [disaster, energy, climate, agriculture, biodiversity]

  9. Usage of GIS & Geoportal • National Cadastral Data Mapping & Urban Planning • Resources & Environment Management • Telecom and Network services • Accident Analysis and Hot Spot Analysis • Transportation Planning & Traffic Density Studies • Agricultural Applications • Disaster Management and Mitigation • Determine land use/land cover changes • Navigation (routing and scheduling) & Surveying • GIS based Digital Taxation • GIS Applications in Geology • Assets Management and Maintenance • Irrigation water management
