Geolocation file validator

Geolocation file validator is a free browser tool that produces complete source-linked findings, exact parsed source index and named working tables from RFC 7946 GeoJSON and approved field or relationship rules. Working results use exact local sources and explicitly selected versions.

Free. No account or payment needed.

What does the geolocation file validator produce?

Check GeoJSON coordinates, geometry structure and approved required properties.

Use the exact local files and task-specific inputs listed below. Preparation and review stay in this browser. Inspect all findings before preparing the finalized pack.

What do you need before you start?

  • Define the authorized source population and your review rules.
  • Keep the unchanged original files and record the snapshot and exclusions.
  • Review missing and invalid inputs before preparing the finalized pack.

What information do you enter?

Select the actual local sources and freeze the task-specific inputs below. Keep source files and complete findings private.

  • RFC 7946 GeoJSON. Supported geojson source.
  • Approved field or relationship rules. Exact headings field, type, required, allowed_values, approval_ref
  • Review reference. Customer-controlled review identifier.
  • Responsible reviewer. Owner of the supplied facts and selected method.
  • Observation date. Real YYYY-MM-DD date.
  • Source and version scope. Name actual population, selected source versions and known omissions.

What you can download

Every result must identify its supplied facts, assumptions and unresolved items.

Free resultIncluded downloads

Enter your information, inspect the on-screen result and keep a browser backup.

Editing and direct copies of your entered information stay free.

  • Complete source-linked findings, exact parsed source index and named working tables.
  • Seven formal/data core files plus two exact originals. PDF, DOCX, Excel, CSV, JSON, file hashes and instructions use the shared formal renderer.
  • Integrity-checked browser backup, exact-byte restore and separately preserved earlier forms, files and historical purchases.

These supported outputs are free. No checkout is required.

How does the geolocation file validator work?

  1. 1
    Select the actual sources

    RFC 7946 GeoJSON. Supported geojson source.

  2. 2
    Freeze the review rules

    Inspect RFC 7946 GeoJSON geometry, Feature and FeatureCollection structures. Check numeric longitude/latitude bounds, coordinate dimensions, line lengths, closed rings, ring winding, bounding boxes and declared required properties. Preserve null or empty geometry as unresolved. Flag antimeridian segments and unsupported coordinate reference systems. A structural check does not prove land location, area, ownership or due diligence.

  3. 3
    Inspect complete findings

    Review all source-linked results and unresolved items. Free JSON and CSV preserve complete results.

  4. 4
    Keep recoverable work

    Original files and exact input strings save in this browser. Restore validates identity, schema and actual file hashes before replacing current work. Earlier browser work and historical purchases remain separate.

  5. 5
    Prepare the finalized pack

    Prepare seven core files and the exact selected attachments, then download them free. Review the fictional sample below.

Common questions

What information does the geolocation file validator need?

Enter RFC 7946 GeoJSON. Supported geojson source; approved field or relationship rules. Exact headings field, type, required, allowed_values, approval_ref; review reference. Customer-controlled review identifier; responsible reviewer. Owner of the supplied facts and selected method; observation date. Real YYYY-MM-DD date. Define the authorized source population and your review rules.

What does the geolocation file validator produce?

Complete source-linked findings, exact parsed source index and named working tables. Seven formal/data core files plus two exact originals. PDF, DOCX, Excel, CSV, JSON, file hashes and instructions use the shared formal renderer. Integrity-checked browser backup, exact-byte restore and separately preserved earlier forms, files and historical purchases. Review unresolved findings and limitations before use.

Who makes the final decision?

A responsible person reviews the result. Working results use exact local sources and explicitly selected versions. Originals remain unchanged in this browser. No source authenticity, population completeness, vulnerability exploitability, legal applicability, license conclusion, consent validity, food safety or external submission is established.

Is this tool free?

Yes. The on-screen result and listed downloads are free. No checkout is required. Keep local backups and review the stated method and limits.

Can I use the geolocation file validator for this task?

Check coordinate formats, geometry and required attributes. Working results use exact local sources and explicitly selected versions. Originals remain unchanged in this browser. No source authenticity, population completeness, vulnerability exploitability, legal applicability, license conclusion, consent validity, food safety or external submission is established.

What still needs review?

Working results use exact local sources and explicitly selected versions. Originals remain unchanged in this browser. No source authenticity, population completeness, vulnerability exploitability, legal applicability, license conclusion, consent validity, food safety or external submission is established.

Up to 20000 positions and nesting depth 30. Topological self-intersection, geodesic area and parcel ownership are not evaluated.

Each source supports at most 10 MB. Table sources support 5000 rows, 50 fields, 100000 cells and 5000000 parsed characters. JSON documents support depth 40 and 100000 nodes.

Working artifacts are produced only when their required named checks pass. Complete findings remain available even when an artifact is withheld.
