GISAgentBench - Terrain Modeling and Hydrological Analysis: leaderboard
The Terrain Modeling and Hydrological Analysis family of GISAgentBench (University of Florida, 2026): 63 tasks that derive slope, drainage, watershed and flow products from elevation data. Strict task success rate in percent against exact ground-truth output files under deterministic checks; higher is better.
Metric: Strict task success rate (%; share of the 63 Terrain Modeling and Hydrological Analysis tasks whose output file matches the exact ground-truth output within the task's declared tolerance under deterministic structural and value checks, no LLM judge; LangChain ReAct agent over a fixed harness of 128 GIS APIs backed by QGIS, GDAL and GeoPandas; 50 tool calls per task, temperature 0, one run per task, July 2026).
