GIS-based mapping ready to start soon in Mumbai

Mumbai, November 9 – After a delay of almost a year, the financial capital is finally set to have Geographical Information System (GIS) enabled maps that will not only record the city’s 3 lakh properties but will also mark every road, tree, dustbin and manhole in a locality alongside the vital installations. This will allow Mumbaiites to view these details on a map at the click of a mouse even as the Brihanmumbai Municipal Corporation is able to keep an eye on property tax defaulters, water leakages and miscreants who regularly encroach on or rupture the city’s pipelines.

However, it will be another two years before the facility is finally ready.

Starting with the one of the smallest wards, mostly B Ward in South Mumbai, the pilot project for the GIS map and property mapping is expected to begin in the next four months.

The GIS maps will be prepared using Quick Bird Satellite images with the highest possible resolution for the land that will allow recording of the smallest features. The final maps are expected to be complete within two years.

While tenders were invited in May this year, the civic administration made several revisions to the plan. “The project has been delayed but we wanted the implementation to be up to date. Many cities have followed the system but in a haphazard manner, we did not want to do the same,” said joint municipal commissioner (improvements) V Radha.

As per the new provisions, along with the entire 468-sq km area of Mumbai city and its vital installations—dams, water lakes, pumping stations, purification centers—will be digitally mapped. Along with property mapping, four major departments will also have their data recorded: water supply, sewage, roads / traffic (including transportation facilities like bus stands, taxi stands and petrol pumps) and storm water drains. Mapping of underground water utilities, sewer lines, drainage lines, storm water drains will begin independently.

In the property mapping, each property in the city with the name of the property owner, its type (flat, bungalow, chawl), its usage and carpet area will be mapped digitally and physically. Once completed, the mapping will allow the property tax department to identify the defaulter — tax payment will be automatically linked with a software and the map will highlight defaulting properties automatically.

Similarly, the civic administration hopes new properties will also be brought into the property tax net through the mapping.

The National Informatics Center (NIC) which has already delayed the submission is now expected to hand over the base maps by next year.
The base maps will provide 3D images with low flying photographs for comparison with the satellite images and the ground mapping. Details of other departments will then be superimposed on these maps. Once complete, the digital maps will also be uploaded on the civic portal.

“Barring confidential information which includes data on properties and vital installations, the basic data of roads and directions will be uploaded for citizens’ convenience,” Radha said.
