How GeoJsonCoordShield Works in 3 Simple Steps โš™๏ธ

Zero configuration, zero cloud server dependencies, instant execution.

01

Load Raw GeoJSON FeatureCollection or Line-Delimited GeoJSONSeq

Drop RFC 7946 .geojson files containing Point, LineString, Polygon, or MultiPolygon telemetry and features[].properties directly into browser RAM.

02

Coarsen Coordinate Precision & Scrub Feature Properties PII

AST-aware geometry walkers round [lon, lat] tuples and bbox bounds to privacy-safe decimal precision while masking emails, VINs, and Mapbox sk.* keys.

03

Export Topology-Valid GeoJSON for Git, PostGIS or AI Debugging

Preview 70% of the sanitized GeoJSON FeatureCollection immediately or unlock 100% export and the air-gapped Offline PRO HTML workstation for $19 one-time.

Frequently Asked Questions for GeoJsonCoordShield โ“

Everything you need to know about privacy, local memory execution, and buyouts.

Why is sharing raw 15-decimal GeoJSON files a severe GDPR and HIPAA privacy violation?โ–ผ

Six to fifteen decimal places in WGS84 [longitude, latitude] coordinates pinpoint a person's exact bedroom or clinical visit within millimeters. Under GDPR Art. 32 and HIPAA Safe Harbor, precise home and trajectory coordinates coupled with feature properties constitute protected personal data.

Why does running sed to truncate decimal numbers break GeoJSON files?โ–ผ

A global regex like sed 's/(\.[0-9]{2})[0-9]+/\1/g' blindly alters floating-point billing amounts, timestamps, and version strings inside features[].properties, and can collapse small Polygon rings so the first and last coordinates no longer match.

How does GeoJsonCoordShield prevent GitHub GH013 and Gitleaks blocks on GIS repositories?โ–ผ

Developers frequently export GeoJSON debug snapshots containing Mapbox secret tokens (sk.eyJ*), Google Maps keys (AIza*), or customer PII inside properties. GeoJsonCoordShield scrubs those tokens while coarsening coordinates in one pass.

Will Turf.js, Mapbox GL, and PostGIS ST_GeomFromGeoJSON still accept the sanitized output?โ–ผ

Yes. GeoJsonCoordShield preserves valid RFC 7946 FeatureCollection structure, geometry types, and LinearRing closure while keeping all property keys intact.

Are my GeoJSON files ever uploaded to a remote map server?โ–ผ

Never. All JSON AST parsing, coordinate quantization, and Canvas spatial bounding-box visualization run 100% locally in your browser RAM with zero network egress.
