Subject: [MapProxy] WMTS service origin challenge
Message-ID: <CANnM9TewRvmNUf6owTKxp-Qh+PG+ougtTJu8iU0tXUz6qhBkEg@mail.gmail.com>

Hi, I'm having difficulty configuring a WMTS service to land in the correct
geography. I believe it is due to the source service origin (X: -2.00377E7 Y:
3.02411E7). I have tried and tried without luck so I am reaching out. I
hope someone else has come across this and can point me in the right
direction. Configuration below.

Thanks,
Jared

## MapProxy 1.15.1

## WMTS services
https://tiles.arcgis.com/tiles/TJH5KDher0W13Kgo/arcgis/rest/services/

## DRAPE 2008 & DRAPE 2014 overlay fine bringing them into QGIS from their
source services

## They do not overlay with after routing through mapproxy

## I believe due to the different origin on the 2008 DRAPE

## I can't figure out proper grid
