Re: [mapserver-users] Doubling of labels on high resolution maps

2019-10-17 Thread lars . schylberg 
Hi,

The best way is most likely to set up a WMTS service with mapcache.
It handles meta tiling in a more proper way.

There are good examples in the mapproxy documentation how to do labels in 
mapserver. 
https://mapproxy.org/docs/nightly/labeling.html 
(https://mapproxy.org/docs/nightly/labeling.html)
Mapproxy is anotther good alternative instead of mapcache.

Be sure to specify "labelcache_map_edge_buffer" "-10" in the mapfile MAP-WEB 
data section.

You can still run WMS requests from QGIS towards mapcache if You have enabled 
that in the mapcache config.

There is a "tile_metatile_level" configuration directive that should solve this 
problem:

https://mapserver.org/output/tile_mode.html 
(https://mapserver.org/output/tile_mode.html)

but it does not seem to work for WMS layers.

So I used the underlying PostGIS layer in QGIS, and that works OK, of course. 
Not sure if this is a bug in MapServer, though.

Thanks for your help,

Partials FALSE may help, but based on the screenshot it is possible 
that print composer is making requests with some overlap.

Re: [mapserver-users] Dynamic wfs_onlineresource

2019-10-17 Thread Matthias Müller 
Yves,

thanks for the hint - it works, but produces an ugly URL that exposes
the FS-Link of the mapfile to the public:

https://server1.org/mapserver/?map=/opt/service/mapserver/mapfile.map&"/
>

I should have mentioned that a reverse proxy runs in front of
Mapserver, that adds the mapfile to the request:

  location /mapserver {
# Add header for CORS requests
add_header Access-Control-Allow-Origin *;

# Load from /etc/init.d/mapserv
fastcgi_pass 127.0.0.1:;

# Rewrite url to hide mapfile path
rewrite ^(/mapserver.*)?(.*)$
$1?map=/opt/service/mapserver/mapfile.map$2 break;

include fastcgi_params;
fastcgi_param SCRIPT_NAME /usr/bin/mapserv$fastcgi_script_name;
  }

Is there another solution that works in conjunction with my reverse
proxy? Many other server products respect proxy headers and substitute
the filds of the private internal URL scheme with the corresponding
elements of the public URL of the caller.

Matthias,

Just remove the parameter will imply that MapServer will find the correct
online resource.

[mapserver-users] Dynamic wfs_onlineresource

2019-10-17 Thread Matthias Müller 
Hi,

we are running WFS services with similar mapfiles on different servers.

Setting the "wfs_onlineresource" is straight forward, but requires a
hard coded host name:

First server:
  WEB
METADATA
  "wfs_title"  "myserver"
  "wfs_onlineresource" "https://server1.org/mapserver?;
  "wfs_srs""EPSG:4326"
  "wfs_enable_request" "*"  # necessary
END
  END


Second server:
  WEB
METADATA
  "wfs_title"  "myserver"
  "wfs_onlineresource" "https://server2.org/mapserver?;
  "wfs_srs""EPSG:4326"
  "wfs_enable_request" "*"  # necessary
END
  END


I there way to let mapserver figure out the hostname from the request
and create the appropiate links in the WFS capabilities accordingly?

Something like:

  WEB
METADATA
  "wfs_title"  "myserver"
  "wfs_online
resource" "{request protocol and hostname}/mapserver?"
  "wfs_srs"  
  "EPSG:4326"
  "wfs_enable_request" "*"  # necessary
END
  END
