#17118 reopened defect

Sort out axis=neu for EPSG:4326

Reported by: Don-vip Owned by: team
Priority: normal Milestone:
Component: External imagery source Version:
Keywords: projection wgs84 axis wmts Cc: wiktorn


We define EPSG:4326 with axis=neu since r8584 to get WMTS working:

# WGS 84
<4326> +proj=lonlat +datum=WGS84 +axis=neu +bounds=-180,-90,180,90  <>

Yet we have currently the Saxony latest aerial imagery WMTS in Maps/Germany which defines its EPSG:4326 tile matrix as follows:

    <TopLeftCorner>11.7 51.7</TopLeftCorner>

We cannot use this matrix with JOSM as it assumes the coordinates being inverted, resulting in negative tile coordinates. This makes the imagery integration test fail (see #16073).

Who's wrong? Saxony's WMTS server or us?

Is there an 1.3/1.1 difference similar to WMS for WMTS?

Replying to stoecker:

Is there an 1.3/1.1 difference similar to WMS for WMTS?

No, there is only one version of WMTS specification.

I've cross-checked in QGIS and there - projection 4326 also fails (using default settings).

But in QGis there is an option: "Ignore axis orientation (WMS 1.3/WMTS) and with this checked - this layer works in 4326.

So it looks like "well known bug" in WMTS implementation in some servers

OK, I've sent them an e-mail and will ignore the error until we get a response.
