Monnet Ispat Ltd. a steel Company established in the state has been allotted with land for establishment of the steel plant with integrated power plant in Dhenkanal district. The assignment involved preparation of the study of the forest land involved and preparation of Geo-referenced map. The process involved identification & establishment of primary control points (PCP) along the pipe line and the conveyor corridor with reference to the ORSAC known points (SOI national grid), identification of the secondary control points and DGPS observations of the permanent ground features for the revenue cadastral maps involved in the project. Geo-referencing of the revenue cadastral maps for delineation of the forest land followed by staking-out and demarcation of the forest boundary along the pipeline and conveyor corridor through RTK based DGPS devices. The outcome of the survey was used to generate the slurry pipeline alignment map on a cadastral base showing the forest land involved along with the forest boundary coordinates.
The GIS/DGPS based geo-referencing of pipeline and conveyor corridor helped in
- Delineation of the forest land involved in the plant area (pipeline and conveyor gallery) along with identification of the change point coordinates of the forest land within the coal block
- Compliance to the MoEF for approval
