We all knows about GIS , ie Geographic information system. Simply we can describe as Geographical Information System is any system that captures, stores, analyzes, manages, and presents data that is linked to location. When we consider GIS technically we can explain as, it is a system that includes mapping software and its application to photogrammetry, remote sensing, land surveying, aerial photography and photogrammetry, mathematics,mapping, geography, and tools that can be implemented with GIS software. Still, many refer to "Geographic Information System" as "GIS" even though it doesn't cover all tools connected to topology.We can also consider GIS as the merging of cartography and database technology.
Let us check various trends and applications in GIS Technology
• GIS and Science—3D analysis, graphing and data exploration, and more
•Customization and Application Development- It includes Design and Development
• Creation / Maintenance of Geo spatial Database - Design, Development and maintenance of custom geospatial databases
• Data Integration and Data Format Conversion - Also includes Spatial Analysis and Modeling
• Map Digitization / Vectorization - Digitizing maps
• Feature Extraction - 2D, 3D feature extraction using AT( aerial triangulation) results
• Ortho photography - Orthophoto Rectification and Mosaicing
• Network Analysis - Design spatial database and model features on a 3D surface for network analysis used by organizations/agencies.
• Web Mapping / Web GIS - Geodatabase Designing & Modeling, Web Mapping Automation
• Geo-Coding - Important point with mapping is registering a map with the correct real world coordinates,ie Image Georectification / Georeferencing
• GIS and CAD — Building information modeling (BIM), 3D GIS, and more
• Enterprise GIS—Extending geospatial capabilities to the enterprise
• Server GIS—Delivering geospatial services through a wide variety of clients
• Mobile GIS—Making the mobile workforce more efficient
• Cartography—Additional cartographic mapping, analysis, and editing tools
• Lidar data processing - Mapping and laser scanning
There are various many other applications in GIS technology, which can be discussed in more detail later in next article.For more details and for any queries contact http://www.sblgis.com/contact.aspx
