Convert KML to TopoJSON

KML or Keyhole Markup Language is a collection of geospatial data on map and commonly used in Google Earth or google services. TIFF (also known as Tagged Image File Format) is a file format for transferring, storing, and displaying raster images. Scanned aerial photography and maps, as well as digital satellite imagery and other geographic data, can be found in this file format.

A TopoJSON file format is a format that encodes topology. TopoJSON is an extension of GeoJSON. This format contains both geospatial data (arcs) and attribute data. In contrast to other GIS formats TopoJSON uses arcs. Arcs are sequences of points, while line strings and polygons are defined as sequences of arcs.

You can convert KML to TopoJSON  file using IGIS Map Tool. You can also use it for other GIS data Conversion.
