Mumbai: The Slum Rehabilitation Authority (SRA) has begun using advanced technology to capture pictures of slums in the city as a part of biometric survey conducted by them. During the survey, the consultants have been using pano cameras in place of lidar cameras in order to get a 360-degree-view of the smaller lanes located inside the slum pocket.
The biometric survey is being conducted by members of MahaOnline Survey Limited company appointed by SRA who visits the hutments and slum structures for the survey
“These cameras are not costly as the lidar cameras which cost at least Rs 3 crore. They are portable as they can be carried easily by holding it in the hand and the surveyor is able to walk inside the smaller lanes of a slum pocket,” said a senior SRA official.
The lidar cameras are the ones which are carried on the back and it automatically click pictures as the surveyor moves inside the slums. “It becomes difficult for the surveyor to enter smaller lanes by carrying the lidar cameras as they are huge and requires a larger space to enter the lanes. This has caused inconvenience in our survey work which caused several delays,” added the official.
The pictures clicked using pano cameras would be tagged with the pictures clicked using drone cameras. Both the data would be combined using the location of the huts in order to get a three dimensional image of a slum structure in the city. In January, the authorities conducted demarcation of the sprawling slums in Vikhroli via ‘drone camera’s (phantom four PRO). At least 2300 slums were identified using the drone cameras and it captured the pictures of slum pockets within a span of 25 minutes.
The SRA has used drone in the area as its pilot project for accurate demarcation of slum clusters in the area. This new technology has allowed the authorities to know the outer demarcation of the slum pockets which are spread out in a particular area. “We are yet to scan through the images captures by the drone cameras. We will use drone cameras to capture other slum structures once we finish scanning the photos,” added the official.
