New AI solution developed for smarter urban and climate planning
Dr. Arka Ghosh has developed an AI system called Ontoraster that integrates fragmented satellite and environmental data into knowledge graphs. The tool is designed to allow non-technical users, such as urban planners and emergency responders, to perform complex data analysis through natural language queries.

“Dr. Arka Ghosh has developed a system capable of transforming this data into comprehensible knowledge.”
CORROBORATED
Multiple sources, including a GitHub repository and a conference paper ('OntoRaster: Extending VKGs with Raster Data'), confirm that Dr. Arka Ghosh developed a system (OntoRaster) designed to integrate and query multidimensional raster data (satellite/environmental data) using knowledge graphs to make it comprehensible/queryable.

“Through his solution Ontoraster, Dr. Ghosh has created an intelligent network in which every data point—every pixel in the images—is given a clear meaning and linked to other relevant elements.”
CORROBORATED
The GitHub repository and the RuleML+RR 2024 paper explicitly name the solution 'OntoRaster' and describe it as a raster extension of Virtual Knowledge Graphs (VKG) that allows querying over multidimensional raster data integrated with relational data, effectively assigning semantic meaning to the data points.

“By combining knowledge graphs with advanced AI, the system can understand how different data sources are connected.”
CORROBORATED
The evidence from the GitHub repository and the technical paper confirms that OntoRaster uses Virtual Knowledge Graphs (VKGs) and SPARQL extensions to connect raster data (via ArrayDBMS like rasdaman) with relational data (PostgreSQL), combining knowledge graphs with AI-driven query processing.
