Regional Plan 2021 to be georeferenced for Gati Shakti integration
Panaji:
State govt on Tuesday decided to transform maps of the existing non-georeferenced Regional Plan of Goa (RP), 2021, into georeferenced raster and vector formats for integration into the PM Gati Shakti State Master Plan.
The master plan is a national initiative aimed at transforming infrastructure and logistical planning across the country.
Georeferencing involves the aligning of satellite imagery or other types of maps with real-world geographic coordinates. Maps in the raster format are composed of pixels, while those in the vector format are defined by mathematical equations that describe lines, curves and shapes.
Goa govt will appoint a consultant who will georeference and digitise the RP 2021, incorporating the suggestions and inputs provided during the course of preparation, and as may be required as per the town and country planning (TCP) department.
The TCP department has recognised a critical need to convert existing non-georeferenced PDFs and AutoCAD files of RP 2021 into georeferenced datasets.
Maps will be georeferenced using data from the land survey department as reference points. The georeferenced maps will undergo strict quality control to ensure that the raster data perfectly corresponds to the land survey data. GIS thematic maps will be generated from the digitised data, with an expected accuracy of 0.25mm.

A senior official said that the digitised shape files will contain accurate and complete attribute data, corresponding to geographic features within the maps. 'Special attention will be given to ensuring consistency between spatial data and attribute data,' the official said.
The consultant will ensure that all steps in the project undergo rigorous quality control to ensure the data is accurate, reliable, and meets the specified standards. 'To maintain high data quality and ensure that the final outputs align with the expectations of the TCP department, a comprehensive verification process will be implemented,' the official said.
