Introducing CityJSON

Hi group,

At the end of last year I had a discussion with Hugo Ledoux of Delft University. He and some others have created a spatial data format called CityJSON and are looking for options to further develop and possibly standardize this format.

CityJSON is an encoding of CityGML, an open standardised data model and exchange format to store digital 3D models of cities and landscapes. CityGML is implemented as an application schema for GML3, and it is an official international standard of the OGC.

CityJSON is an alternative encoding in, you guessed it, JSON. The aim of CityJSON is to offer an alternative to the GML encoding of CityGML, which can be verbose and complex. CityJSON aims at being easy-to-use, both for reading datasets, and for creating them. It was designed with programmers in mind, so that tools and APIs supporting it can be quickly built. It was also designed to be compact, and friendly for web and mobile development. See http://www.cityjson.org/ for more.

Because the SDWIG is all about web-, programmer-, and mobile development friendly standards, I think CityJSON could be of interest to this group.

Any thoughts, opinions?
