KML Editor

KML Editor provides a focused, data-centric environment for editing and validating KML files used in GIS, Google Earth, and mapping workflows. It is designed for GIS analysts, developers, cartographers, and surveyors who need reliable syntax, valid geometry, and correct styling in their KML payloads. The tool operates on text input of KML content or on a loaded file and emphasizes correctness, interoperability, and repeatable results.
Conceptually, the tool parses KML as XML, checks against known KML constructs (Placemarks, Points, LineStrings, Polygons, Styles, GroundOverlays, Regions), and validates coordinate formats and altitude semantics. It supports formatting options such as pretty-printing and minification, along with an optional auto-fix pass that resolves common structural and encoding issues while preserving user intent. The core logic remains deterministic: parse, validate, optionally fix, and produce a clean KML sample plus an error report.
Who benefits: data engineers preparing map layers, field teams exporting KML from GIS systems, educators demonstrating KML structure, and developers building mapping apps that consume KML. Unique value comes from strict schema awareness, clear error signaling aligned to line/column positions, and a lightweight, offline workflow that avoids reliance on external services. Core features include syntax validation, element-level checks, coordinate normalization, style preservation, and detailed diagnostics. Typical use cases include repairing malformed placemarks, extracting a feature summary, and exporting a ready-to-import KML for Google Earth.
Outputs and efficiency: users receive a corrected KML payload, a structured error list with codes and positions, and a compact summary. The tool is designed for quick iterations in data-prep pipelines, batch validation via API, and accurate troubleshooting without requiring full GIS software.
