Solution Architecture

A platform-independent data model is designed with the help of a 3-Key information model comprising a spatial database server, a geospatial server, and an application server. A mobile application also fits into this information model relaying information to users.

Database Creation

IIIT Hyderabad developed a 3-Key-based ranking model for lakes which can give ranks for lakes based on the three spatial data sources. As part of the 3-Key model, three data sources are used to calculate the ranks. The legal boundaries of the lakes are picked up from digital toposheets and temporal variations of these lakes are studied from satellite data sources available in the open domain. For studying the temporal variations, multispectral satellite data of different time periods is taken, and a classification matrix is built to calculate physical characteristics, such as maximum water extent.
