This document discusses how spatial data analytics and mapping can help manage cities in the digital age. It provides examples of how remote sensing, mobile data, and other sensors are creating big data that can help address urban challenges if properly leveraged by government agencies. Specifically, it analyzes Bengaluru's rapid growth rate, loss of water resources, urban heat island effect, and mismatch between service provider boundaries to demonstrate the potential of spatial data and analytics. Visualizations of municipal information and metrics like public access to transit are presented as well. Opportunities and challenges around business models, data access, regulations, and scaling solutions are highlighted for discussion.

SPATIAL DATA ANALYTICS AND
MAPPING TO MANAGE CITIES

2. INFORMATION IN DIGITAL AGE….
• Cities are increasingly investing in technologies and digitisation (land records,
property tax)
• Digital India, Smart Cities, AMRUT, Startup India, National GIS vision and other
programs are creating conducive ecosystems
• Open and proprietary technologies are helping to find some solutions in our cities
• Remote Sensing, Mobile data, other sensors are creating big data
• Yet Data is hard to get in our cities…!
• Government agencies yet to properly leverage these ecosystems (data analytics,
inter agency coordination)

18. FOR DISCUSSION
• How technology is increasingly helping to find the targeted
solutions for urban issues
• Impact on ground – how public and agencies are getting
benefitted
• Challenges and opportunities
– business model
– finding the right data
– regulatory framework
– scaling up the across geographies
