We, GSI, are distributing the web map data "GSI Tiles" as open data and are also releasing the web map site "GSI Maps" using FOSS as open source under the open policy in order to make our national geospatial information available to as many people as possible.
In this effort, while we have so far continued to provide a stable supply of map tiles in image format mainly, we are also interested in promoting map tiles that can be flexibly used at a lower cost. To this end, in recent years, we have released vector tiles on a test basis and tried building a scheme from production to consumption of vector tiles with the use of FOSS.
