GIS Comprehensive Knowledge Base V1.0

What problem it solves

GIS work often gets stuck between coordinate systems, format choices, software versions, quality acceptance, scripting, and hard-to-reproduce failures. GIS_SKILL_V1.0 organizes this scattered knowledge into a searchable knowledge base, helping engineers define data boundaries, tooling paths, and acceptance criteria before execution.

Core capabilities and workflow

• Seven-stage workflow: requirements lock, data insight, plan generation, environment prep, execution, quality self-check, and archive, with logs and diagnostic reports at each step.
• Standards and practice: covers GB/T, data production, quality inspection, acceptance, and delivery for domestic surveying and geographic information workflows.
• Software and development: includes ArcGIS Pro, QGIS/PyQGIS, FME, PostGIS, WebGIS, Cesium, GEE, and point-cloud processing topics.
• Pitfalls and retrieval: provides 160+ anti-patterns, keyword mappings, and version-difference guidance to reduce time spent on issues like ERROR 999999, map shifts, and topology errors.

Boundaries

This is a knowledge base and working protocol, not a substitute for testing in real software environments. Some standard clauses, advanced commercial features, and online services remain subject to official versions. When using dual-version files, verify the requested version and avoid mixing 3.6 and 3.7 content.
