Re: [mapserver-users] Mapcache support for multiple format types

[Cechini, Matthew F. (GSFC-423.0)[Science Systems & Applications, Inc.]]

A compelling situation could be a layer that has uses cases where you want it 
have transparency or not, making it an “overlay” or “base layer” respectively.

Though, if you’re serving it as 24+1bit PNG with transparency, you’re gonna 
lose quality in JPEG, so you would probably want to return a 24bit PNG.  And at 
that point, you would have to have separate layers because the mime type is the 
same.

As an aside, a member of our team did work on a JPNG approach where tiles that 
require transparency are PNG and those that do not are JPEG.  The devil is in 
the details of quality mapping with that though.

Hi Tom,
My question wasn't clear, or you did not answer my question ;-)
I was looking for a compelling *use-case* where the solution requires a tile 
server to support both jpeg and png for a given tileset. My stance for mapcache 
is that the data producer (i.e. you as the mapcache administrator) knows his 
data and therefore which format (*singular*) is best suited for a given 
tileset. I'd be happy to revisit my judgment if presented with a scenario where 
more than one format per tileset is actually needed.

Cheers,
Thomas

Really, its just so that we don't need to have 2 separate layers in the
service for each format type. The norwegian mapping authority has about 25
cache 'services' and so its a bit messy in the config and WMTS capabilities
file if we have to have 50 tilesets instead of 25.

Its no problem technically having 2 tilesets called 'topo2_png' and
'topo2_jpeg' for example (they would have the same title and abstract), it
just would have been preferable for us to have 1 layer support multiple
formats so that the client could call the same service/layer/tileset and
choose the format type through the kvp parameter. Not a show-stopper for us,
we just have to change our way of thinking :)

Re: [mapserver-users] Can't get capabilities xml error message

[Rahkonen Jukka (MML)]

Hi,

I believe that a quick fix is to edit your mapfile and change " opérations " 
into "operations".  Non-ASCII character should be OK if you save the mapfile as 
UTF8 which is a requirement nowadays in any case. Plain ASCII mapfiles still do 
work even if they are saved as Latin1 or something.

I can get a map in FireFox. 
I can't get the WMS with Qgis : failed to load capabilities (traduction from 
french, sorry) Indeed, I can't get the capabilities in FF either with  : 
http://10.210.1.32:8080/cgi-bin/mapserv.exe?...\fond_mapserver.map=1.3.0=WMS=GetCapabilities;

here's the message :
 

Previously I had a message beginning by "mandatory metadata...'. I worked on my 
mapfile and then get this last message just above.

here's my mapfile : 
MAP
 WEB
METADATA
"wms_title" "WMS-Inrap, aide au montage des opérations"
"wms_onlineresource"
"http://10.210.1.32:8080/Apache/cgi-bin/mapserv.exe?MAP=C:/ms4w/map/fond_mapserver.map&;
"wms_enable_request" "*" 
"wms_srs" "EPSG:2154 EPSG:3857 EPSG:900913"
"wms_encoding" "UTF-8"

END
END

All layers have METADATA with wms_title and wms_srs (even if this last param is 
not required because I have a PROJECTION object).
I feel a little lost.
Thanks

Re: [mapserver-users] Mapcache support for multiple format types

[thomas bonfort]

There is no support for multiple formats per tileset (yet?), as I could not
imagine a compelling use-case that would warrant it. Would you care to
explain why this would be needed?
