I have processed a fair amount of GeoTIFFs of Sentinel-2 imagery, which i use for tracing in areas with old or low-res imagery. Currently I’m using Mapbox Studio to supply a background, but it is limited to 5 GB of storage, (a~100x100km tile from this source is 460MB and I have dozens of them). Instead of constantly uploading the tiles whenever I need one, maybe I could host them locally, which would also allow me to allow other mappers using the service.
I followed the instructions here and here, but it’s very concise and so far I only got the OSM Carto server running. My own layer stays entirely blank, and the WMS also gives a ‘cannot load tiles’ error. Hopefully someone can give me some
I modified the example setup file to the following:
services: #sets up how to make the source data available demo: tms: wms: #srs sets the coordinate reference systems as which you want to make your data available. MapProxy reprojects the source data very well to these projections. srs: ['EPSG:900913','EPSG:3857'] image_formats: ['image/jpeg', 'image/png'] md: # metadata used in capabilities documents title: Copernicus Sentinel-2 2017 abstract: void online_resource: https://scihub.copernicus.eu/dhus/ contact: person: Your Name position: Technical Director organization: Some Company address: Long street city: Timbuktu postcode: 123456AD country: South Pole email: firstname.lastname@example.org access_constraints: This service is intended for private and evaluation use only.

In this example it is used for the osm_tiles source. These settings are correct for openstreetmap.org tiles. #The google mercator srs is used (also called EPSG:900913), and the origin of the tiles is north-west). If you get this wrong, you might very well get an all-blue world. srs: EPSG:900913 origin: nw globals: #next are some global configuration options for MapProxy. They mostly explain themselves, or can be looked-up in the MapProxy docs. cache: # where to store the cached images base_dir: './cache_data' # where to store lockfiles lock_dir: './cache_data/locks' # image/transformation options image: resampling_method: bilinear jpeg_quality: 90
Layers: should be fine, it shows up in the web interface and opens
caches: i understand that raster tiles can only be served via a cache, but otherwise it’s a bit unclear. It could be that it goes wrong at this point
sources: I pointed the URL to my local file, the documentation says this is the accepted method for serving local files. I am not sure if I need to choose a different grid than the OSM default.
Here is an example tile equivalent to the one I used: http://pan.baidu.com/s/1nv9IKBZ
So, can someone have a look at my configuration file to point me in the right way?
Edit: i solved it using Maptiler https://forum.openstreetmap.org/viewtopic.php?pid=650380#p650380
