Shapefile to KML Converter

This tool converts ESRI Shapefile data to KML for use in Google Earth and other GIS apps. It accepts a shapefile bundle (.shp/.shx/.dbf) and preserves attribute data while converting coordinates to WGS84 when required. It supports single-file and batch processing, handling points, lines, and polygons. The system reprojects coordinates to EPSG:4326 for KML compatibility and emits features as Placemarks with ExtendedData for attributes. For workflows with multiple shapefiles, each input is processed independently and exported as corresponding KML features, enabling straightforward sharing and visualization across platforms.
Conceptually, the tool reads geometry and attributes, detects the source CRS, performs a coordinate transformation to the standard KML CRS, and writes a structured KML document. This approach minimizes manual steps and reduces risk of misalignment between formats. Users benefit from reliable data interchange and simplified publication to map viewers and Earth browsers.
Unique value lies in automatic CRS handling, batch capability, and robust attribute support, which together shorten data preparation cycles and improve interoperability. Core features include input validation, CRS handling, geometry preservation, attribute mapping, and batch export. Typical use cases include urban planning datasets, environmental surveys, and educational geospatial demonstrations where rapid, repeatable shapefile-to-KML conversions are required.
