[MapProxy] Mapproxy shows tiles in wrong position

[anil maharjan]

Hi,


I am using Mapproxy to display map http://maps.stamen.com/toner/#3/49.78/-4.04. But the tiles are shown in wrong position. For example:


Map without zoom:<https://i.stack.imgur.com/JL7Ac.png>

Map with one level zoom:<https://i.stack.imgur.com/Gn3Bn.png>

More zoomed, the image looks even more odd.

Mapproxy configuration:

layers:
  - name: StamenToner
    title: StamenMap
    sources: [stamen_cache]

caches:
  stamen_cache:
    grids: [stamen_grid]
    sources: [stamen_wmts]

sources:
  stamen_wmts:
    type: tile
    url: http://tile.stamen.com/toner/%(z)s/%(y)s/%(x)s.png
    grid: stamen_grid

grids:
    stamen_grid:
        srs: 'EPSG:3857'
        origin: 'nw'
        tile_size: [512, 512]


I have no idea why the tiles are in wrong position when zoomed. Any suggestions.

Regards,

Anil
