What this system is
This system is a spatial analysis library built on PySpark that indexes and traverses geometric shapes using the H3 hexagonal grid system. It provides functions to convert geometries into H3 cells and calculate distinct neighbor cells within a specified distance. The implementation includes robust null handling and supports GeoJSON output for spatial boundaries.
Features
Added spatial indexing and traversal functions for H3
The \h3-pyspark\ library introduces new capabilities for spatial analysis. Users can now index geometries (Point, LineString, Polygon, and their Multi-variants) into H3 cells using the \index\_shape\ function, which handles complex shapes by densifying lines and checking intersections. Additionally, a \k\_ring\_distinct\ function is added to compute the distinct set of cells within a specified distance from input cells. All new and existing UDFs now explicitly handle null inputs by returning null, and the \h3\_to\_geo\_boundary\ function has been updated to optionally return a valid GeoJSON string.

Test coverage
Organized and expanded test suite for H3 spatial functions
Tests for H3 indexing, traversal, and core library functions have been reorganized into the root-level \tests/\ directory. This includes new dedicated test files for indexing (\test\_indexing.py\) and traversal (\test\_traversal.py\), alongside a refactored \test\_core.py\ that now explicitly verifies handling of null inputs in UDFs.

How this codebase got here
This is the PUBLIC form of this artifact. Findings are listed in full, but the details of SECURITY findings — which rule fired, in which file, on which line, and how to fix it — are deliberately withheld, and any secret-scanner results are excluded entirely. Where detail is absent here it was REMOVED FOR PUBLICATION; it is not missing from the analysis. The complete artifact is available from the repository owner.

kevinschaich/h3-pyspark was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.
About this page
- The score is its most recent published measurement, taken on 21 September 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit dffe8e1dea5d99b0b121cc9282f650a2a262ae72 — the exact code this score is about.
- Scored under rubric-2026.09.15 — the same rubric and the same method as every other entry in this index.
- Measured by watchdog.canine.dev using codehealth-analyzer preprod-fa71c66cabd8.
