Bangalore Development Authority intended to create digital database of all the layouts coming under its jurisdiction to plan and monitor all its developmental activities using geospatial technologies. Bangalore Development Authority from the day of its inception has developed layouts and has made site allotments of about 2 lakh numbers of sites to general public. During the last one decade more than 10 new layouts have been added to the growing city by BDA. The authority has more than 1500 map sheets in hardcopy format which requires to be converted into digital layers for access, search, discovery as well as updation for planning and administration.

Objective

The main objective of the assignment is to digitize layout maps of BDA using geospatial technologies and integrate them on a GIS platform.

The estimated cost of converting paper maps into digital maps using geo-spatial technology is expected to be around Rs. 1 crore. Digitization work will be taken up in phases and each time 50 maps are expected to be released from BDA for digitization.

Methodology

Scanned sheets available with BDA about 1000 will be taken up for integration in the 1^st phase in a phased manner. Retracing of maps for about 200 layout maps available with the department will also be taken up in the 1^st phase. In the 2^nd phase maps available with BDA in severely damaged shape will be taken up for retracing and reconstruction using latest geospatial techniques and high resolution satellite imageries (wherever Google images suffice it will be used in reconstruction of the maps).

To begin with all the soft copies available with the department for the planning districts will be integrated with Bangalore city map with proper georeferencing. Changes in land use would also be done in consultation with the officials of the department to all the layout maps. The hard copies will be taken up for integrating with Bangalore city map in the second phase.
