[mapserver-users] Setting MBR of layers displayed

[Tony Baylis]

Good morning all, hope you enjoyed the weekend.

I am using mapserver retrieving data from a PostGIS database and have a
client who wants to have one map covering a large area, containing six
different prospect locations.  Each prospect has different data requirements
and I need to set the legend/map up so that when a user zooms into one
prospect the detailed layers of all the other prospects are not drawn (or
tried to be drawn) or shown in the legend as is the case when using
maxscaledenom etc.

Essentially I want to set an MBR so that the layers are drawn only when the
map is within that MBR and a the right zoom scale.

Cheers in advance.

[mapserver-users] WMS Server problem

[Tony Baylis]

Hi guys,

Apologies for adding another question related to a similar previous post but
I too am having problems getting MapServer to serve a WMS layer.  At this
stage I can't get a GetCapabilities (it wants to download the mapserv file)
or Mode=map to work via the browser. I have been able to get the layer to
render correctly using openLayers in WMS mode however.

Below is my basic mapfile and openLayers file.  Note I have stripped most of
the styling out of the mapfile.

[mapserver-users] map projection problem

[Tony Baylis]

Hi All,

I'm a bit confused as to the way mapserver deals with projections.  My
understanding is that if I place a 'PROJECTION' tag as a high level object
in the mapfile, then that is the projection I should expect when I read
coordinates from a tool such as Chameleon's cursorpos widget.

If I then have layers using data of a different base projection I need to
place a 'PROJECTION' tag within the 'LAYER' object describing the projection
of the base layer.  This will ensure all layers even if they are different
projections will reproject correctly and layers will render in the correct
position relative to each other.

If the above is correct can someone explain why I my map is rendering in the
projection of the base layers rather than the projection I define in the
mapfile level 'PROJECTION' object.  See below for me example mapfile.

[mapserver-users] WMS Client and SLD

[Tony Baylis]

All,

This is the first time I have tried styling external WMS data using SLD 
and cannot get the returned data/image in the desired style.  Below is 
the simplified mapfile and SLD file.  If anyone has any pointers I'd be 
more than grateful.  Please note that the link to the SLD file does work 
with the following return: 56

Re: [mapserver-users] AGG Rendering problem

[Tony Baylis]

Thanks to Rahkonon and and Paul for their responses but neither solved 
the problem.  I eventually moved a map from my existing working 
mapserver/agg instance to the rebuilt one and after doing the required 
bits to point it at the right data IT also did not work in AGG rendering 
mode.


I then removed all layers and started adding them back to the map one by 
one to see if it was a problem with the layer setup somewhere...sure 
enough one of the layers was referencing a symbol in the symbolset that 
AGG obviously dislikes.  Once I removed the 'SIZE' criteria from the 
'STYLE' AGG rendering worked.  Since putting the original map together I 
have created another (better) symbol for this object and using this all 
is working well.


So there you have it...a symbol working with standard rendering but not 
with AGG, the result being the application seemed to lose connection.

Hi,

Try adding MIMETYPE to outputformat. I guess that without it Mapserver is using default for jpeg requests. If you use, while testing, your own mimetype like 
MIMETYPE "image/jpeg2"  and in request use &FORMAT=image/jpeg2 you should be able to compare what happens with image/jpeg and image/jpeg2.  If jpeg2 works you know that Mapserver if using your own imageformat because otherwise image/jpeg2 would not be recognised. Then rename AGG MIMETYPE to image/jpeg and see if the output now seems to be generated by AGG.

Aihe: [mapserver-users] AGG Rendering problem

Hi all,

This is my first post in a long time so be gentle...My 
problem is I have finally updated an old server to use 
MapServer 5.4.2 and want to use AGG rendering  I have done 
this without a problem on another server earlier in the year 
but for some reason whenever I add the 'OUTPUTFORMAT' 
section and remove 'IMAGETYPE' I get a Connection Lost type 
error from the browser.  Replace 'IMAGETYPE' and the 
connection is restored but the map is definitely not anti-aliased.


Below is the relevant section from my mapfile and below that 
the output from a ./mapserv -v.  Both outputs match the 
server that works.


#IMAGETYPE JPEG
OUTPUTFORMAT
  NAME "AGG_JPEG"
  DRIVER "AGG/JPEG"
  IMAGEMODE RGB
END

./mapserv -vMapServer version 5.4.2 OUTPUT=GIF OUTPUT=PNG 
OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG 
SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV 
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_CLIENT 
SUPPORTS=FASTCGI SUPPORTS=GEOS INPUT=TIFF

INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

Here's hoping you can help.
