‘It will help in detecting encroachments and layout plan violations’
Rajya Sabha member V. Vijaya Sai Reddy on Friday launched the ‘Change Detection Software’ pilot project at the VMRDA office, which was initiated by the Visakhapatnam Metropolitan Region Development Authority (VMRDA) to monitor land-use technology.
Mr. Vijaya Sai inquired about the functioning of the system. VMRDA Commissioner P. Koteswara Rao explained that the project was taken up in association with Environmental Systems Research Institute(ESRI). The lands belonging to VMRDA will be monitored by using DGPS survey data and Geographic Information System(GIS) software. The GIS-based applications can be used to detect encroachments and layout plan violations.

VMRDA Commissioner P. Koteswara Rao conducted a video-conference with ESRI to finalise the modalities of using GIS technology to map the lands belonging to VMRDA in the district, here on Thursday.

“With constant urbanisation and changing topography, a practical tool to monitor the lands has been in the reckoning for the past few months. Keeping that in mind, VMRDA is moving towards high-end technologies and web applications using accurate DGPS survey data and GIS software to monitor changes in its lands real-time, at the mere click of a button,” he said.
