The Mapbox Vector Tile spec is catching on. We are pleased to announce that Esri is the latest company to embrace this open format for fast and efficient distribution of tiled geodata.

Esri made the announcement last week at their annual developer conference as they revealed that they are building a mapping framework on top of vector tiles.

According to several Esri devs, they plan to contribute improvements to the specification on, which is exciting. Open specifications describe open formats, and open formats are the backbone of open data.
