Re: [mapserver-users] wms_style_xxx_legendurl_href

[Jörg Thomsen]

Hi,

o.k., it was not the best moment to ask my question, because at the same 
time the mapserver beta 6 was announced ;)


so here a 'repost', it would be nice if anyone could give me a hint:


Hi,

I'm using the wms_style-parameters in the layer metadata section to tell
the client to use a special legend-url:
'wms_style' 'Farbwerte'
'wms_style_Farbwerte_legendurl_height' '218'
'wms_style_Farbwerte_legendurl_href' 'http://xxx/html/test/gimp.png'
'wms_style_Farbwerte_legendurl_format' 'png'
'wms_style_Farbwerte_legendurl_width' '300'

This works fine with only one style. But what do I have to do, if I have
defined different styles / classgroups? one should use a pre-defined image,

> the other ones should be generated by mapserver.

When defining
'wms_style' 'Farbwerte'
the capabilities only shows this style, even if there are more styles
(classgroups) defined.

Any idea?

Jörg

Vince,

There are no mechanisms to utilize a PHP image object as the
data in a mapserver raster layer without first writing to disk.  I
gather PHP image resources are actually a handle to a gdImage
object, so if you needed it badly enough it should be possible to
write a PHP function that turn that gdImage into something that
was accessable to GDAL as a raster but that would be quite
involved and not something likely to go back into the core
distribution.

Best regards,

For the raster image you can build pyramid with gdaladdo, it's really useful
to increase performances

[mapserver-users] GeoWebCache WMS

[Eric Weisbender]

Hello,
 
I am trying to use the GeoWebCache WMS service, 
http://maps.opengeo.org/geowebcache/service/wms ( 
http://maps.opengeo.org/geowebcache/service/wms ), with cgi MapServer as a 
layer defined in may mapfile and it doesn't work.  It also doesn't work in 
QGIS, GlobalMapper, or Google Earth.  However, It works fine in may OpenLayers 
app.  Any insight as to why it only works with OpenLayers would be greatly 
appreciated.
 
Thanks

Re: [mapserver-users] Nodata in raster queries

[Frank Warmerdam]

On 11-03-14 03:23 PM, Boss, Ken (DNR) wrote:

I have a DEM that I am using with mapserver 5.6 to service queries for an 
elevation value at a given point.  The DEM contains significant offsite/nodata 
areas.  From gdalinfo:

Band 1 Block=19063x1 Type=Int16, ColorInterp=Gray
NoData Value=-32768

If I open the image in QGIS and use the identify tool over a nodata area, it 
says:

   Band 1  null (no data)

But when I run a mapserver point query at the same point, the value returned is 
-32768.  Is there a way to configure mapserver to return something more like 
null for raster nodata areas?


Ken,

Mapserver has a few mechanisms for specifying nodata.  I skimmed the
raster query code and it does not seem to honour these.  If you file
a ticket on this issue, I can try and implement nodata support in the
raster query code this week at the code sprint.

In MapServer 6.0 (trunk) there are some improvements to detecting nodata
values, even for non-8bit data, in the raster drawing case.  This just
hasn't all made it into the raster query logic.

RE: [mapserver-users] About html code inside query attribute responses

Can you or someone else share a sample shapefile with HTML in an attribute? 
I've not experienced this problem but donw have access to a datafile with that 
type of content...

Thanks Steve.

As you already pointed out [item name=”name” escape=”none”] behaves exactly as 
[name_raw], which in my case translates html tags from <…> to 
 . Not a 
really coherent behavior, is it?

Asunto: RE: [mapserver-users] About html code inside query attribute responses

What you describe is basically correct. Except, there is no code in place to 
translate html elements like you mention with [attribute item name_raw]. That 
should be the correct method of telling MapServer not to touch the contents of 
an attribute at all. You could also try:

  [item name=”name” escape=”none”]

That should generate the same output as [name_raw] and is the preferred way of 
doing this sort of thing.

Subject: [mapserver-users] About html code inside query attribute responses

Hi,

I’ve prepared WMS getFeautreInfo queries so that mapserver’s template receives 
pure html attributes (containing the  tag for example). I would like to 
show this html code as it is. So that it integrates with the existing html 
header, footer and the rest of the template inside mapservers response, hoping 
that at the frontend the html response could be interpreted as a whole. 
However, the html stored data is shown either as escaped html or as url encoded 
data. I’ver read mapserver documentation but I had not success while 
implementing each possible solution:

If I try:

[attribute name] : I get escaped html ( is translated into 
)
[attrribute name_esc]: I get url encdes text ( is translated into 
%3Cbr%2F%3)
[attribute item name_raw]: I get something in between but not pure html ( 
is translated into \n).

Mapserver documentation says “…By default the attributes are encoded especially 
for HTML representation” but I now disagree.

Any ideas about what’s happening here? Any workaround solutions?

Thanks in advance,

Manuel Aymerich

Re: [mapserver-users] GeoWebCache WMS

[Bart van den Eijnden]

Hi,

it's a tiled service, so only imagery at certain scales. That's why it does not 
work in regular WMS clients, only tiled (WMS-C) clients.

Best regards,
Bart

Re: [mapserver-users] GeoWebCache WMS

[Mark Korver]

GlobalMapper has been updated in ver 12 to work with tiled services,
but I have not tried WMS-C with it.

MapServer will also work with tiled services from gdal ver 1.7+ see

http://www.gdal.org/frmt_wms.html

Another angle on this is to put MapProxy in front of it which is easy
way to wms a tms source and get both for the price of one?
