I am trying to create an offline version from here:
https://wmts.maptiler.com/aHR0cHM6Ly9ubHMudGlsZXNlcnZlci5jb20vZnBzVVpieHRndGtuL2luZGV4Lmpzb24/wmts
and here is my current config:
services:
demo:
wms:
md:
title: OS 10k 1888
tms:
origin: 'nw'
layers:
- name: osgb10k1888
title: OS 10k 1888
sources: [osgb10k1888_cache]
caches:
osgb10k1888_cache:
sources: [osgb10k1888_wmts]
grids: [webmercator]
sources:
osgb10k1888_wmts:
type: tile
grid: webmercator
url: https://nls-0.tileserver.com/fpsUZbxtgtkn/%(z)s/%(x)s/%(y)s.jpg
grids:
webmercator:
base: GLOBAL_WEBMERCATOR
This all seems to work fine with the resulting levels and resolutions matching the source correct:
Level and Resolutions
Level Resolution
0 78271.51696402048
1 39135.75848201024
2 19567.87924100512
3 9783.93962050256
4 4891.96981025128

7 611.49622628141
8 305.748113140705
9 152.8740565703525
10 76.43702828517625
11 38.21851414258813

14 4.777314267823516
15 2.388657133911758
16 1.194328566955879
17 0.5971642834779395
18 0.29858214173896974
however the resulting bounding box is:
-20037508.342789244, -20037508.342789244, 20037508.342789244, 20037508.342789244
I have tried adding the bbox to the grid based on the source:
<ows:LowerCorner>-7.793077 49.852539</ows:LowerCorner>
<ows:UpperCorner>1.790425 60.894042</ows:UpperCorner>
but this the screws up all the resolutions and causes the map to be misaligned
do i need to add all the res into the grid and specify the coords instead of using the web global default?
