Online map from ArcGIS rest service misaligned

[Pierre-Felix Breton]

Hi!

I am trying to load tiles from a a webservice providing information about snow coverage.

--------------------------------------------------
The web server url is :

https://mapservices.weather.noaa.gov/raster/rest/services/snow/NOHRSC_Snow_Analysis/MapServer/0

When loaded in QGIS, the results looks like this (correct):



--------------------------------------------------
When using this web service in GuruMaps, I get this  (also correct):


The url used in Gurumaps to retreive tiles is:

https://mapservices.weather.noaa.gov/raster/rest/services/snow/NOHRSC_Snow_Analysis/MapServer/export?dpi=96&transparent=true&format=png32&layers=show%3A3&bbox={$bbox}&bboxSR=3857&imageSR=3857&size=512%2C512&f=image

--------------------------------------------------
In OsmAnd, I get this result (note the misalignment of the images compared to the background map:




The URL used in OsmAnd to define the map source is this:

https://mapservices.weather.noaa.gov/raster/rest/services/snow/NOHRSC_Snow_Analysis/MapServer/export?bbox={bbox}&format=PNG32&layers=show:3&transparent=true&f=image

--------------------------------------------------
I have attached my osf file containing the online map source to make debugging easier, if interested (load it and find the online map source entitled "NOAA Weather - Snow Coverage (Web Map Tiles)"

I am puzzled as to why OsmAnd don't align the images correctly like QGIS or Gurumaps.  Any advice would be appreciated!
