Welcome to

-

-This server distributes maps to desktop, web, and mobile applications. -

-

-The mapping data are available as OpenGIS Web Map Tiling Service (OGC WMTS), OSGEO Tile Map Service (TMS), and popular XYZ urls described with TileJSON metadata. -

Wrong configuration of the "BaseURL" in tileserver.php

-

-Please modify 'tileserver.php' file and replace the '' in the $config variable with '' (with slash in the end) or other correct address to your server. Multiple CNAME can be used for better performance - more in readme.txt. -

No maps available yet

-

-Ready to go - just upload some maps into directory: / on this server. -

-

-Note: The maps can be a directory with tiles in XYZ format with metadata.json file.
-You can easily convert existing geodata (GeoTIFF, ECW, MrSID, etc) to this tile structure with MapTiler Cluster or open-source projects such as GDAL2Tiles or MapTiler or simply upload any maps in MBTiles format made by TileMill. Helpful is also the mbutil tool. Serving directly from .mbtiles files is supported, but with decreased performance. -
