Do any tile generators create a description file that can be retrieved? If not, does anyone here have any influence that could get them to? For my program that displays tiles I keep a list of tile servers. For each one I try to populate the following fields:
Server Name: Label to show user when selecting a tile server Link: URL of "home page" of the server TileURLPattern: URL containing X, Y, Zoom, etc. to be substituted WebmapURLPattern: URL pattern for opening a web page at a Lat/Lon/Zoom Copyright: Copyright notice to be displayed with these tiles ZoomMin, ZoomMax: range of zoom levels available LatMin, LatMax, LonMin, LonMax: geographic area covered Transparent: flag to tell that tiles are transparent For example: OpenStreetMap http://openstreetmap.org/ http://{abc}.tile.openstreetmap.org/{Zoom}/{X}/{Y}.png http://www.openstreetmap.org/?lat={Lat}&lon={Lon}&zoom={Zoom} (C) OpenStreetMap contributors 0, 18 (since this server covers the whole world no lat/lon limits) It seems like any tile generating software should be able to automatically populate a small text file with at least the zoom and lat/long bounds of the set of tiles available. These are facts about a tile server that change periodically and it would be nice if the server itself could tell us what the current values are since they are hard to automatically discover. If you are curious, my list of server descriptions (which probably contains outdated information) is at: http://vatavia.net/mark/VataviaMap/servers.html My tile map display software (Windows, VB.Net) is at: http://code.google.com/p/vataviamap/ -- Mark Gray _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
