2026-06-23 Text-to-QueryPlan for Moving Objects Databases Dataset doi:10.57760/sciencedb.39997 en The SECONDO Moving Objects Dataset is an open, tool-agnostic release of real spatio-temporal data for research on moving objects, geospatial analytics, and Text-to-QueryPlan generation. It bundles three resources: (1) berlintest, the complete Berlin BerlinMOD test database — public-transport networks, city geometry and 562 train trajectories; (2) nanjingtest, a Nanjing geospatial collection — administrative districts, city/university boundaries, the full road network and points of interest; and (3) a text-to-query benchmark of ~100 representative (plus 596 total) natural language questions paired with gold SECONDO executable query plans across eight spatio-temporal query categories.All objects are converted out of the native SECONDO nested-list format into ordinary structured storage: UTF-8 CSV with geometry as OGC WKT, GeoJSON, and exploded per-segment / per-vertex / per-sample-point tables, so the data loads directly into pandas, QGIS, PostGIS, DuckDB, GeoPandas, etc. moving objects; spatio-temporal; Text-to-QueryPlan 王撷阳 PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
