Topographical Surveys

Topographical Surveys

Topographical surveys for engineering designs for road corridors, Railway lines, Power line routes, Details and Utility surveys of built up areas, Water projects and Irrigation schemes. Topography maps are widely used maps, these showcase not only the natural resource like roads, transmission line, country borders, major buildings etc. Production of an accurate topographic map can take a long and complex process, but we employ the modern day processes, an extremely professional team of technicians and a series of co-ordinate steps, so that the process requires comparatively lesser amount of time.

We produce assistance of computer technology to makes it easier to produce new maps easily and revise the existing ones. Improved and effective processes have replaced the old ways of compiling information to deliver new maps. World wide acceptance of computer produced maps has accelerated the use of computer compatibility of topographic mapping services. Even the government departments opt for digital mapping information for their networks. These are used for the following features:

 

  1. Disaster management
  2. Engineering and Architecture purposes
  3. Defense and Security
  4. Infrastructural services
  5. Route planning
  6. Geographical representation of thematic data
  7. Telecom and Transport services

Digitizing Data:Map digitization resembles the original map but it indulges each and every physical and digital feature of the map to be segregated according to location, classified and traced. Different layers of man made features like buildings, roads, railway tracks and physical features like boundaries, surfaces, rivers etc require digitization.

These maps can be digitized by hand, tracing maps with cursor and even done by the phenomenon of scanning. After digitizing remaining editing operations take place. The attributes like coding is integrated to identify what each digitized symbol depicts; and controlling the accuracy of attribute positioning and coding.

Topography mapping techniques are used to map down all "physical" natural and man-made objects hunt down into a single database in order to gain varied information as:

  1. Marketing- For any organization that is thinking to enlarge its area under business, to merge sales information in geographic terms.
  2. Soil Conservation- Department of agriculture and soil conservation use scanned photographs and field boundary data to check and analyze soil use and area under crop cover.
  3. Hydrology Studies- Urban flood modeling, storm drain modeling, pond design, river channel studies and modeling is done by the study of these digitized maps.
  4. Land Development- Planning of different features like sewer, plots, cost estimates, paving, drainage and material take offs is done by these maps.
