<div dir="ltr"><div><div><div>Hi Thomas, <br><br></div>thanks for your help, that does it. Great!<br><br></div>@Robert, atm I'm using leaflet and this provides boolean L.Browser.retina property that can be used to check whether the client has a higher pixel ratio. It also has a detectRetina option for the tileLayer, but since we need to switch tile/gridsets I'm not sure whether this can be used. I'm sure other clients will have something similar.<br><br></div>Cheers, Michael<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">2017-01-24 20:00 GMT+01:00 Robert Sanson <span dir="ltr"><<a href="mailto:Robert.Sanson@asurequality.com" target="_blank">Robert.Sanson@asurequality.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal" style="margin-bottom:12.0pt">I would like to know if anybody had success in using mapcache to provide tiles for usage on retina displays? There seems not to be the one default strategy to do so, but IIUC the baseline is to provide a bigger
tile (512x512 instead of 256x256) for the some extent. <u></u><u></u></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Now the question is, how to generate with mapcache an additional cache with big tiles (512) but can be accessed using identical tile requests? By identical, I mean that the xyz numbers stay the same, but a different
tileset name is used (e.g. <a href="http://basemaps.at" target="_blank">basemaps.at</a> does that) or using MapBox's "@2x" modifier.
