<p><span lang="FR-CH"> </span>My goal is to reproject a WMTS source in EPSG:21781 into
EPSG:4326, as a WMTS service (or eventually a WMS service). This is working
fine for projection like EPSG:2056 (LV95), EPSG:3857 (webmercator) or EPSG:4258
(ETRS89). But using EPSG:4326, I get some strange result.</p><p></p>
<p>Checking the result in the MapProxy Demo page, using the
EPSG:4326 ans the WMS service:</p><p></p>
<p><a href="http://mf-chsdi3.dev.bgdi.ch/mom_fix_1594/mapproxy/demo/?srs=EPSG%3A4326&format=image%2Fpng&wms_layer=ch.swisstopo.zeitreihen_20031231" target="_blank">http://mf-chsdi3.dev.bgdi.ch/mom_fix_1594/mapproxy/demo/?srs=EPSG%3A4326&format=image%2Fpng&wms_layer=ch.swisstopo.zeitreihen_20031231</a></p><p></p>
<p>we find that there is *no* data West of the prime meridian
of (city of Bern, if you know Switzerland, 600'000m easting or about 7.5° West
in WGS84).</p><p></p>
<p>The same layer, using the WMTS service, displays the same
problem:<br></p><p></p>
<p><a href="http://codepen.io/procrastinatio/pen/XmWEZL?editors=001" target="_blank">http://codepen.io/procrastinatio/pen/XmWEZL?editors=001</a></p><p></p>
<p>The prime meridian is one of the vertical purple line.</p><p></p>
<p>In comparison, using EPSG:4258 (ETRS89), which is "almost"
identical to EPSG:4326, data are displayed correctly both side of the meridian, as shown in the demo</p><p></p>

<p>We are using MapProxy Version 1.8.0 and the configuration
file is <a href="https://raw.githubusercontent.com/geoadmin/mf-chsdi3/master/mapproxy/mapproxy.yaml" target="_blank">https://raw.githubusercontent.com/geoadmin/mf-chsdi3/master/mapproxy/mapproxy.yaml</a>
(very long).</p><p><br></p><p></p>
<p>If anyone has a hint, I would be glad.</p><p><br></p><p></p>
<p>Thank you in advance!<br></p><p></p>
