How this service works
Audit up to eight GIS-layer manifests for missing dependencies, CRS mismatches, boundary vintages, join uniqueness, missing values and geometry issues. No uploads, map files or network fetches.
Output
Returns a structured audit report covering: dependency and component completeness per layer, CRS/EPSG mismatch flags relative to the project CRS, boundary vintage discrepancies, join key uniqueness and match rate analysis, missing value summaries, and invalid geometry counts — all without uploading files or making network requests.
Example use cases
Pre-analysis spatial data quality check
“Before I run my spatial join, audit these two layers: one is a geojson in EPSG 4326, present, checksum-verified, 1000 rows, 998 unique geoid keys, 995 matched rows, 3 missing values, 0 invalid geometries, 0 missing components, boundary year 2022; the other is a shapefile in EPSG 4326, present, checksum-verified, 1000 rows, 997 unique geoid keys, 994 matched rows, 1 missing value, 2 invalid geometries, 0 missing components, boundary year 2022. Project is EPSG 4326, boundary year 2022.”
Multi-layer CRS consistency audit
“I have four GIS layers for a regional planning project — can you check them for CRS mismatches and boundary vintage inconsistencies? Layer 1: geopackage, EPSG 4326, present, checksum-verified, 800 rows, 800 unique geoid keys, 798 matched rows, 0 missing values, 0 invalid geometries, 0 missing components, boundary year 2020. Layer 2: shapefile, EPSG 3857, present, not checksum-verified, 800 rows, 795 unique geoid keys, 790 matched rows, 4 missing values, 1 invalid geometry, 0 missing components, boundary year 2019. Layer 3: geojson, EPSG 4326, present, checksum-verified, 750 rows, 748 unique geoid keys, 745 matched rows, 2 missing values, 0 invalid geometries, 0 missing components, boundary year 2020. Layer 4: csv, EPSG 0, present, checksum-verified, 750 rows, 740 unique name keys, 735 matched rows, 8 missing values, 0 invalid geometries, 0 missing components, boundary year 2020. Project EPSG 4326, boundary year 2020.”
Election district shapefile integrity audit
“Audit my election district shapefiles before I publish — I have two layers. Layer 1 is a shapefile, EPSG 4269, present, checksum-verified, 435 rows, 435 unique geoid keys, 435 matched rows, 0 missing values, 0 invalid geometries, 0 missing components, boundary year 2020. Layer 2 is a csv, present, checksum-verified, 435 rows, 430 unique geoid keys, 428 matched rows, 3 missing values, 0 invalid geometries, 0 missing components, boundary year 2020. Project is EPSG 4269, boundary year 2020.”
Technical details
Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/research/map-source-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, serverless audit of GIS layer metadata without uploading actual files or triggering network fetches — ideal for pre-flight validation pipelines, CI/CD spatial data checks, or agent-driven data quality reviews where you already have layer statistics in hand. It supports up to 8 layers simultaneously with cross-layer CRS and boundary vintage comparison, making it more thorough than single-layer validators.
Side effects
- More than 8 layers submitted — API enforces a maximum of 8 items
- Missing required layer fields such as epsg, rows, or joinKey cause validation errors
- EPSG values out of the 0–999999 range are rejected
- boundaryYear values before 1900 or after 2100 are rejected
- matchedRows or uniqueJoinKeys exceeding the rows count may produce inconsistent audit flags
- Remote format layers with no checksum verification may result in incomplete audit output
