<div style="font-family: Verdana; font-size: 12px; line-height: normal;">now i am trying to deploy mapcache with tiff-write-support, but there are no options which i could set in the CMakeList or CMakeCache File. I am using the master branch from the git repository. Should i use another version or is their a simple option string which i have to add?</div>

<div>Arthur,
<div> </div>
<div style="">The TIFF cache backend is efficient and performant, however it is not easy or flexible to setup. Basically you *must* ensure that the provided TIFFs are exactly aligned to your mapcache grid, and this for every zoom level you want to serve.</div>
<div style="">I would suggest you create a TIFF cache from scratch on the "test" datasource , by enabling tiff write support in mapcache. Once you have browsed/seeded a few layers, the structure of what mapcache is awaiting given the <template> you provide will hopefully be clearer.</div>
<div style=""> </div>
<div style="">Remove the <base> from your tiff source, use only the <template> and give it a full path, e.g.</div>
<div style="">
<div> <template>/path/to/tiff-cache/{tileset}/{grid}/L{z}/R{inv_y}/C{x}.tif</template></div>
<div> </div>
<div style="">Please submit a patch to the docs if you think they should be enhanced.</div>

<div>Hello Mapserver-Community, Hello List,</div>
<div> </div>
<div>first of all i want to thanks for the great work you guys are doing. The mapserver-project with all his facets does really deliver a great range of useful tools and services for different questions.</div>
<div><br/>
Right now i am looking for a WMS and WMTS solution for publishing big amounts of high resolution tiffs. Because of concerns about our disk storage i would like to use only a single raster datastore for both services, i.e. WMS and WMTS. </div>
<div> </div>
<div>The realization of a WMS Service in front of a tiff datastore is no problem with mapserver / mapfile. For the realization of a WMTS solution i set up the extension mapcache. I also got it running as disk cache solution. But i want to try if it is possible to set up it in front of the tiff datastore. As it says in the documentation (<a href="http://mapserver.org/mapcache/caches.html#mapcache-cache-tiff" target="_blank">http://mapserver.org/mapcache/caches.html#mapcache-cache-tiff</a>) it is possible to use a gtiff cache, but right now i didn't get it running (see my mapcache.xml in annex). Also i don't have real knowledge about the structure of the tiff store for mapcache. As far as i know gdal gives me with the tools gdal2tiles and gdal_retile/gdaltindex two tools for computing a tile structure. Could such a structure reused or do i have to use another structure? Anyway i am quit new to tiling storys, so maybe i just don't get it.</div>
<div> </div>
<div>It would be nice if somebody could show me mapcache.xml example for a tiff cache and maybe could also descripe the needed structure of the tiff store. I really appreciate your help. Thanks in advance.</div>
<div><br/>
Kind regards,</div>
<div><br/>
JM</div>
