deck.gl is a GPU-powered framework that enables the creation of high-performance, interactive spatial visualizations for large datasets through composable visual layers.
City2Graph is a new Python library that converts geospatial data into heterogeneous graphs for spatial analysis and Graph Neural Networks, with a peer-reviewed paper published in Computers, Environment and Urban Systems. It supports morphological, transport, mobility, and proximity graph construction, integrating with PyTorch Geometric and other graph tools.
This paper presents a schema-grounded natural language interface for transportation safety analysis that uses a large language model to interpret user queries while preserving deterministic execution against an authoritative database. The framework is evaluated on a Massachusetts transportation safety database, successfully executing all queries and correcting errors in 29% of cases, demonstrating a practical approach to broadening access to safety data.
This paper introduces a composite-move Tabu search algorithm for spatial redistricting that improves solution quality and efficiency while preserving contiguity constraints.
PangeAI is a product offering instant, agent-driven spatial analysis and decision-making capabilities.
