Property enumeration and web mapping of ward 76 Bangalore

Develop a GIS and MIS for e-Governance and corporation administration

Background and Objectives

BMP is the Municipal Corporation of Bangalore City responsible for administering all engineering, health and revenue activities. The city is divided into various wards based on locality for efficient functioning. The project area was 4.9 sq kms covering Ward 76, which represents the prime area of the city with highest revenue collection. The objectives of the project were:

• Development of a model city programme with a real world situation to formulate and develop a geographic and management information system for improving the corporation administration
• Development of database template by collecting and digitizing all property tax assessment registers
• Augmentation through well-planned and managed field surveys along with preparation of notational property maps
  

Key Aspects of the Project

• Played a vital role in the reassessment strategy by easy classification of property depending on landuse, type of construction, floor level of unit, neighborhood, area and front/back street accessibility
• Significantly improved the ability of BCC officials to defend assessments from taxpayer challenges
• Systematic planning for cost-effective infrastructure investment and improved service provision & maintenance
• Tax enhancement projections
  • Calculation based on total number of unassessed properties
  • Checking the actual tax being paid and regularizing the same
  • Rationalising the taxation rates
  • Based on hypothetical revenue model involving 6 representative zones
  • Projected tax enhancement is 120 percent
  • Two-fold increase in tax that could be collected
