KML Generator

About This Tool

This tool converts user-provided geospatial data into valid KML documents suitable for Google Earth, ArcGIS, and other mapping platforms. It accepts structured inputs such as placemark names, descriptions, coordinates in decimal degrees, and optional altitude. The generator enforces KML structure (Document, Folder, Placemark, Point) and can embed metadata within ExtendedData. By handling formatting, escaping, and coordinate normalization, it reduces the risk of invalid KML and speeds up map publishing for developers, researchers, educators, and field personnel.

Workflow and core capabilities: The tool maps input records to KML Placemark elements, formats coordinates as lon,lat[,alt], supports optional styles, and outputs a clean KML string or file. It validates coordinate ranges (-180 to 180 for longitude, -90 to 90 for latitude), ensures unique placemark identifiers, and can batch-process multiple placemarks. Optional features include Folder organization, Description and ExtendedData, and simple Style references. Outputs are machine-readable and compatible with common GIS workflows, suitable for automation and pipelines.

Audience and differentiation: Local government, researchers, educators, and developers benefit from fast, standards-compliant KML generation without manual scripting. Unique differentiators include strict adherence to KML 2.3, batch export, and predictable formatting from common input schemas to KML structures. The tool is designed for integration into data pipelines, with a focus on data integrity, repeatability, and ease of validation in map publishing projects.
