Private KML Map and Placemark File Auditor

Inspect a saved KML map for documents, folders, placemarks, geometry, invalid coordinates, duplicate identifiers and inert external references without opening network links or exposing the map to a server.

Ready. Your working data stays in this browser.

Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.

Why this tool is useful

Review a Google Earth export, field survey, map annotation set or delivery plan for malformed locations and hidden network dependencies before sharing it.

How it works

The browser parses bounded KML as inert XML, walks its folder hierarchy and validates Point, LineString, Polygon, MultiGeometry and gx:Track coordinates.

Practical example

Audit a project map to locate a repeated placemark ID, one out-of-range latitude and a NetworkLink that would otherwise depend on a remote server.

Validation

The calculation is deterministic and explains validation errors instead of silently changing invalid input.

Privacy boundary

Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.

Result passport

Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
