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.

Importance of CAD drafting

CAD drafting services plays an important role in our daily life.CAD is an important industrial art extensively used in all areas and in many applications, including automotive, shipbuilding,aerospace industries, industrial and architectural design, prosthetics, and many more. CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software), and discrete differential geometry.

Because of its enormous economic importance, CAD drawings are the most effective way to document technical drawings and related information in an organized manner. CAD combined with GIS enables data to be analysed geographically.

CAD conversion services ranges from GIS to CAD format conversion,
CAD to GIS format conversion, CAD Drafting, paper to CAD conversions etc.

GIS mapping services

Mapping services are categorized based on user specified specifications.
some of the important services are:
* Custom mapping: Mapping Services and GIS Data for Businesses purposes
* Shoreline mapping: The wet/dry line is the feature mapped as the shoreline on historical photography. Therefore to detemine a representative elevation of the wet/dry line so that our lidar-derived elevation-based shoreline is comparable to earlier mapped shorelines.
* Utility mapping : This mapping experience ranges from in all sort of field ie small corner gas stations, through industrial plants, military installations, to entire towns, and involves every type and construction of pipe and cable - including utilities beneath buildings or other structures.
* Muncipal mapping : Includes mapping of town planning.
* Parcel mapping
* Mapping of reclamation activities
* Wildlife and habitat monitoring
