KML Builder

Purpose-built for GIS workflows, the tool converts structured feature data into a standards-compliant KML 2.2 document. It supports Point, LineString, and Polygon geometries, with optional metadata such as name, description, and ExtendedData. The core output is a single KML string that can be saved as a .kml file or consumed by GIS and visualization pipelines. Conceptually, the tool assembles a Document containing Placemark elements, each embedding geometry, coordinates in lon,lat,alt order, and optional styling. Advanced features include Folder and Style elements, simple schemas, and batch generation from a list of features. The value lies in repeatable, machine-readable export from structured inputs, enabling integration with CSV/JSON pipelines and automated map publishing. Use cases include point placemarks for sites, lines for routes, and polygons for areas, all ready for import into Google Earth or other KML-aware viewers. Core differentiators are strict KML 2.2 conformance, coordinate validation, and the ability to generate either minified or pretty-printed output. Typical workflows involve preparing inputs as a feature list, configuring optional metadata, and exporting a KML string for archiving or distribution.
