Swisstopo, OpenLayers 2 and WMTS

[Christian G.]

Hello and thank you for your support.

I need a push in the right direction.

Our web applikation is still using the OpenLayer version 2 API. We are accessing various map sources, internal and external web Servers and add our own layer data.

I have a new requirement to implement Swisstopo WMTS sources. I’m currently looking at "ch.swisstopo.pixelkarte-farbe" and "ch.swisstopo.swissimage".
I managed to get some tiles, but when I zoom into it, it shifts the Position north/east. Is there an example for OL2 and Swisstopo?

Here is my layer...

var lyr1 = new OpenLayers.Layer.WMTS({
   requestEncoding: 'REST',
   name: "pixelkarte",
   url: ["http://wmts9.geo.admin.ch/"],
   layer: "ch.swisstopo.pixelkarte-farbe",
   matrixSet: "21781",
   zoomOffset: 14,
   dimensions: ['TIME'],
   params: {
                        'time': '20151231'
                    },
   
   formatSuffix: "jpeg",
   style: "default",
   opacity: 1,
   isBaseLayer: true
  });

Hello Christian,

It is a bit more complicated than that. The origin is the same for each tileset, but the resolutions are customs.

Here is a fully functional example in codepen.io with OpenLayers v2 and geo.admin.ch WMTS

http://codepen.io/procrastinatio/pen/doZXjO/

OpenLayers v2 has also the abilitiy to parse the WMTS GetCapabilities document for the service, for instance (webmercator!!!!)

https://www.procrastinatio.org/mercator/wmts-capabilities.html?url=1.0.0/WMTSCapabilities.EPSG.3857.xml

for inspiration. You may use it with http://wmts.geo.admin.ch/1.0.0/WMTSCapabilities.xml. The big advantage here, is that the timestamps for layers is updated automatically.

Regards,

Marc
