When I see some MapServer I usually get deeper and checking how it was done. Recently I found on one server where is avalanche map strange tms url. I haven't seen it before but probably some of you guys will tell me what is this type. I know that 14 is zoom and rest is unknown for me. So if you know what is this tms url type, i will be thankful.

Before visiting this link you have to visit http://mapy.hiking.sk/?zoom=14&lat=6305837.94292&lon=2194989.75612&layers=00BFTTTTTTFFFFFTT to get cookies otherwise, this url below will not load.

  • That URL doesnt work for me, and if I go to mapy.hiking.sk I get a google layer by default - there's some other base layers but my Slovak is a bit non-existent. – Spacedman Feb 12 '18 at 12:10
  • Before visiting this link you have to visit mapy.hiking.sk to get cookies otherwise, this url below will not load. Well I am asking if anybody knows what are others numbers in the url. I don`t speak slovak at all :-D – Bjørson Ålmer Feb 12 '18 at 12:14
  • Got it now! I was hoping that if I could see it on a web map I could see several tiles and infer where the X and Y coordinates were in the URL... – Spacedman Feb 12 '18 at 12:20
  • Ok thanks, url is here mapy.hiking.sk/… – Bjørson Ålmer Feb 12 '18 at 12:20
  • It is a bit strange - the 14 is the zoom, the X and Y are encoded in the 088 and 772 in your example, and the other four parts seem fixed for a given zoom level... – Spacedman Feb 12 '18 at 12:33

Looking at the JS script creating the map, we can see that the layer is of type OpenLayers.Layer.TileCache. This tile cache software uses a 7 components URL, with 1 for the zoom, 3 for X, and 3 for Y. Each of the 3 X and Y components contains 3 numbers at most, so the tile X = 123 456 789, Y=1, Z=10 will be shown as /layername/10/123/456/789/000/000/1.png

I haven't found an official textual definition of this, but it corresponds to the source code and to several comments.

components = ( self.basedir,
               "%02d" % tile.z,
               "%03d" % int(tile.x / 1000000),
               "%03d" % (int(tile.x / 1000) % 1000),
               "%03d" % (int(tile.x) % 1000),
               "%03d" % int(tile.y / 1000000),
               "%03d" % (int(tile.y / 1000) % 1000),
               "%03d.%s" % (int(tile.y) % 1000,
