What's in it
- Data offered docs-verified
- water system (rivers, lakes, reservoirs) · residential areas and facilities · transport (roads, railways, airports) · pipelines (oil pipelines, power lines) · boundaries and administrative divisions · landform and soil · vegetation (forest, grassland) · place names and annotations · survey control points and coordinate grid · PostGIS spatial query and PostGIS SQL execution
- Coverage llm-inferred
- China: national land and major islands (incl. Taiwan, Hainan, Diaoyu, South China Sea islands) · data currency 2019 (2021 public edition)
- Resolution docs-verified
- 1:1,000,000 map scale; no spatial or temporal pixel resolution stated
- Formats llm-inferred
- GDB (input file geodatabase) · PostGIS tables · MCP stdio · MCP over HTTP/SSE/WebSocket via Supergateway
- Access docs-verified
- Underlying data provided free of charge by 全国地理信息资源目录服务系统; service is AGPL-3.0 open source; requires self-hosted PostgreSQL/PostGIS and POSTGRES_PASSWORD env var
Useful for
- Use cases llm-inferred
- FRA context: national river and lake layers for regional water-body mapping · Site context screening: boundary, transport and pipeline layers around a project site · Constraint screening: intersect pipeline or transport features with a study area using execute_sql · Desk-study GIS base layers for China-based projects
- Audience llm-inferred
- GIS analysts · planners · hydrologists (regional context only) · civils engineers (regional context only)
Limitations
- Constraints llm-inferred
- Data currency 2019 for the 2021 public edition · 1:1,000,000 scale is too coarse for site-level or detailed drainage/flood modelling · China-only coverage; CGCS2000 / SRID 4326, not British National Grid (EPSG:27700) · No UK datasets; cannot substitute for UK sources such as OS, EA or NRFA data · Requires local PostgreSQL/PostGIS setup, GDAL/OGR and manual GDB import via scripts before use · Data import is script-based, not an MCP tool; execute_sql allows SELECT only · Maintenance and support commitments are not stated in the docs
