Objective

Creation of Digital Survey Maps for Mapping of Utility Lines and Optical Cables.

Description:

400 km of highway and adjoining ground cadastre information (75 meters on each side) was digitized, containing elements such as streets, houses, and plots. Individual maps were georeferenced using the Gauss-Krueger coordinate system and merged into a single map containing 75 meters on both sides of 400 km of highway.
In the second phase, surveyed geo-coordinate points and information from hand sketched survey data sheets were used to create a digital survey map. The digitized information includes streets, optical cables, electricity lines, fence lines, drain lines, man holes, hand holes, sign poles and fixed points such as kilometer stones. Streets and optical cables were digitized as 'SPLINE'.

In the third phase, the digital ground cadastre information was integrated with the digital survey map and merged to obtain a georeferenced digital map of 400 km of highway. In the fourth phase, merged data was fitted into frames with the title block information, the drilling layout maps and other information.
The data was delivered to the clients in DWG format.

Conversion Method

Automated routine programs.

Techniques
