KML KMZ Viewer

The KML KMZ Viewer parses KML and KMZ files to reveal their structure, coordinates, and metadata without performing map rendering. Conceptually, it decompresses KMZ archives when needed, parses XML with namespace awareness, and builds a navigable data model of Documents, Folders, Placemarks, and geometry. It extracts coordinates as decimal degrees in WGS84 and reports a bounding box for quick spatial context. The tool also surfaces metadata such as names, descriptions, styles, and ExtendedData values for quality checks and pipeline validation. Users range from developers integrating KML data into systems to GIS analysts performing quick audits. Unique value comes from precise parsing, robust error reporting, and the ability to export structured JSON suitable for ingestion into analytics, data catalogs, or transformation steps. Core features include KMZ decompression, geometry parsing for Point/LineString/Polygon/MultiGeometry, coordinate normalization, and optional extraction of extended data and network links for validation. The tool emphasizes data integrity and interoperability, enabling fast validation before GIS processing or visualization.
