KMLReduce optimizes the size of KML files by analyzing and reducing coordinates from polygons contained within the file. This allows you to host the KML file online and use less bandwidth for users and services accessing the file.

KMLReduce works on KML files that contian polygon shapes with many coordinates. Since KML files are created with XML, they can grow quite large when shapes are included that contain hundreds or thousands of vertex points. KMLReduce analyzes the points for each polygon shape and optimizes them using a variation of the Douglas Peucker approximation algorithm. This algorithm calculates the distance between each polygon vertex point to determine which points can be simplified and dropped, while still maintaining the shape's geometry integrity. KMLReduce combines this algorithm with the Haversine formula to calculate the distance between latitude and longitude coordinates within the polygon shapes. Depending on the tolerance level used, KML files can be reduced in size dramatically from their original size.

Reduced KML files will contain far fewer polygon coordinates than their original, yet will still display their original shape integrity.

While KML files can be further compressed with the zip format (to produce KMZ files), KMLReduce produces plain-text, non-zipped, KML files in their original XML format. Optimized KML files may be hosted on your web site or other file hosting services, such as DropBox.
