Study on WetLands

SBL Undertakes A Temporal Study On Wetlands
SBL has ventured into a new temporal study, this time, in the coastal region of Kerala. Satellite imageries are being analyzed over the last four decades to find the decadal variations in the land use of Kole lands of Malappuram and Trissur Districts in the state of Kerala, India.

DEM/DTM Generation

Digital Elevation Model is the representation of earth’s topography using digital methods. Digital elevation model is also called as digital terrain model (DTM). DEMs or DTMs can be represented as original maps, square grids or irregular network of triangles.
The main application of DEM are,

• GIS Services
• Surface Analysis
• Orthophoto generation
• Global Positioning System
• Aerial Photography
• Bare Earth Surface Model
• Base Mapping
• 3D Visualization

Georeferenced data processing services

To georeference something means to define its existence in physical space,which means establishing its location in terms of map projections or coordinate systems. The term is used both when establishing the relation between raster or vector images and coordinates but also when determining the spatial location of other geographical features. Examples would include establishing the correct position of an aerial photograph within a map or finding the geographical coordinates of a place name or street address. This procedure is thus imperative to data modeling in the field of geographic information systems (GIS) and other cartographic methods.These can be done by georeferenced data processing service providers. When data from different sources need to be combined and then used in a GIS application, it becomes essential to have a common referencing system. This is brought about by using various georeferencing techniques. Most georeferencing tasks are undertaken either because the user wants to produce a new map or because they want to link two or more different datasets together by virtue of the fact that they relate to the same geographic locations.
