Very short description about it

Quick overview


From TopoJSON Wiki:

TopoJSON is an extension of GeoJSON. TopoJSON introduces a new type, "Topology", that contains GeoJSON objects. A topology has an objects map which indexes geometry objects by name. These are standard GeoJSON objects, such as polygons, multi-polygons and geometry collections. However, the coordinates for these geometries are stored in the topology's arcs array, rather than on each object separately. An arc is a sequence of points, similar to a line string; the arcs are stitched together to form the geometry. Lastly, the topology has a transform which specifies how to convert delta-encoded integer coordinates to their native values (such as longitude & latitude).
