Google’s historical satellite images for India disappeared
Many scholars and researchers have noted that satellite historical imagery of India over the past two decades has disappeared from Google Earth. This service is relied upon to track changes in topography, forest cover, urbanization, and history. Although satellite imagery from 2020 is still available for certain locations in India, the difference is stark when comparing it to the scrubbed clean historical imagery of Amritsar. Surprisingly, Lahore, Pakistan, which is only 50 km away, still has historical imagery available from the past few decades.

Among the policy’s goals is the creation of an enabling ecosystem for Indian companies that will allow them to make India self-reliant in producing and using their own geospatial data/information and compete with foreign companies in the global space.
