Differential Global Positioning System to update maps, land records in Bengal
The state Land and Land Reforms department have decided to use Differential Global Positioning System (DGPS) for a cadastral survey to update maps and land records in Bengal. The state government has decided to take it up as a pilot project. With its successful implementation, the method will be used for the same purpose in the areas where the task of updating maps and land records is still left. Initially, three mouzas in South 24 Parganas — Hiranmaypur, Miagheri and Baruipur — have been selected where it will be done. There is also a plan to execute the task using the same method at Haringhata in Nadia as well.
Each of the three mouzas is different from each other. One is an urban area, another is semi-urban and the third one is in the rural parts of the district. The areas of Hiranmaypur, Miagheri and Baruipur mouzas where it will be done are 2,133.64 acre, 630.46 acre and 2,471.88 acre respectively.
The decision to utilise the new technology was taken to ensure fast completion of the task. Earlier, the entire task had to be done manually and it used to take at least 40 to 50 days for each mouza. But the use of DGPS system will help in completion of the task within 10 to 15 days. The modern DGPS technology will enable preparation of accurate geo-referenced digital mouza maps and it will be done by identifying the latitude and longitude of different points of the mouza. The land record data and the present cadastral map have already been digitised. It will take around 40 days after the completion of the tendering process to complete the work in the three mouzas.
