GML is for WFS, which is for sending vector data (as opposed to raster 
pictures of data) over the net. Perhaps you're interested in WFS and not 
WMS?

[mapserver-users] Problem creating WMS

[bernardo]

Hello all:

I'm trying to create a WMS, but i need to use it with a client named "gvSIG". 
This program cannot read feature info in type "text/html", only "gml"

   METADATA
  "wms_title"   "Layer"
  "wms_srs" "EPSG:23030"
  "wms_abstract" "Layer"
  "wms_feature_info_mime_type"  "gml"
  #"wms_feature_info_mime_type"  "text/html"
  END

That i wanna do is to show a web page or url for "feature info".

Any ideas?

No, unfortunately there is currently no way to have them not show up. 
However there was discussion of a way to make them non-selectable in an 
email to this list this morning:

http://lists.osgeo.org/pipermail/mapserver-users/2008-March/054997.html


The ability to hide layers in OGC services (WMS, WFS, etc.) sounds 
simple and has been discussed multiple times, but we could never come up 
with a clean way that addresses all the needs, that's why that's never 
been implemented. There are a few tickets in Trac talking about that.

What I would like to achieve is a WMS server where when the user
selects
a layer (e.g. Water) that they see Line and Polygon water features
rendered where the lines are in the database table water_lines and the
polygons are in the table water_polys. All the line features are
rendered first with the polygon features rendered on top of those.

Is it possible with mapserver to define a layer which gets data from
multiple sources? Sort of like nested layers but where the user
doesn't
see the nested layers.

An extension of this would to be also have different tables with
data at
different scales so the 1:20k data would be in water_20k_lines and the
1:250k would be in water_250k_lines.

Throughout all of this the user just sees the Water layer.

Andreas,

What was involved in setting up an Apache module? There was talk about 
doing that as an experiment a few weeks ago on the mapserver-dev list. 
If you are interested in sharing what you've done then I'm sure that 
would generate some interest. Perhaps you could file a ticket and attach

I built a small test case and it seems that the root problem is that the 
function msOWSMakeAllLayersUnique() produces an exception if any layer 
is missing a NAME. In order to allow what you want and make the layer 
name really optional we would need to get rid of that exception.


If we modify msOWSMakeAllLayersUnique() to 'continue' the loop instead 
of returning an exception when it encounters a NULL layer name as follows...


--- mapows.c(revision 7477)
+++ mapows.c(working copy)
@@ -141,10 +169,7 @@
   {
   if (GET_LAYER(map, i)->name == NULL || GET_LAYER(map, 
j)->name == NULL)

   {
-  msSetError(MS_MISCERR,
- "At least one layer is missing a name in map 
file.",

- "msOWSMakeAllLayersUnique()");
-  return MS_FAILURE;
+  continue;
   }
   if (strcasecmp(GET_LAYER(map, i)->name, GET_LAYER(map, 
j)->name) == 0 &&

   msRenameLayer((GET_LAYER(map, j)), ++count) != MS_SUCCESS)



... then the following mapfile block...

LAYER
  NAME layer1
  METADATA
"wms_title" "Layer 1"
"wms_group_title" "Group 1"
  END
  GROUP group1
  MINSCALE 0
  MAXSCALE 1
  TYPE RASTER
  STATUS ON
  DATA layer1.tif
END

LAYER
  # NAME intentionally omitted...
  METADATA
"wms_title" "Layer 2"
  END
  GROUP group1
  MINSCALE 10001
  MAXSCALE 10
  TYPE RASTER
  STATUS ON
  DATA layer2.tif
END


... produces the following output in GetCapabilities ... this whole 
group can be turned on/off at once using LAYERS=group1 in the GetMap 
request. Notice that layer 2 has no name in GetCapabilities which is 
what we wanted. Omitting the layer name for layer 1 as well would make 
it non-selectable as well:



  group1
  Group 1
  group1
  
layer1

Layer 1

  
  


Layer 2

  




We would also need to update the WARNING text to say "optional" instead 
of Mandatory.


If this is indeed what you were trying to achieve then please file a 
ticket and I'll make the required changes in MapServer 5.2.

Re: AW: [MAPSERVER-USERS] Hiding overviews

I had a quick look at this thread and it seems to me at first that using 
GROUP in all layers corresponding to the same set of overviews should 
allow you to turn all of them on/off at once.


With respect to this proposed change, I don't see why it would be needed 
since the layer.name is optional and if omitted in your layer in the 
mapfile will simply be omitted in the GetCapabilities, giving the 
behavior that you are looking for. The wms_name is a metadata used by 
CONNECTIONTYPE WMS only AFAIK, it should not be used by the WMS server 
code unless I'm mistaken.


I'll have a deeper look and try to better understand the problem and get 
back to you all.

Eichner, Andreas - SID-NLK wrote:
 


Ok guys. I examined the situation and came to the conclusion that it is
a bug in MapServer.
In the source of mapserver v5.0.2, file mapwms.c, line 1071:


msOWSPrintEncodeParam(stdout, "LAYER.NAME", lp->name, OWS_WARN,
 "%s\n", NULL);

should really be


msOWSPrintEncodeMetadata(stdout, &(lp->metadata), "MO", "name",

OWS_NOERR,

"%s\n", NULL);

since the code conflicts with the comment in the code on line 1747 in
the same file which states:
  "Layer Name is optional but title is mandatory."
Which exactly agrees with the specs which states at page 25 of v1.3.0:

"7.2.4.6.2 Title
A  is mandatory for all layers; ..." and

"7.2.4.6.3 Name
If, and only if, a layer has a , then it is a map layer that can
be requested by using that Name in the LAYERS parameter of a GetMap
request. A Layer that contains a  element is referred to as a
"named layer" in this International Standard. If the layer has a Title
but no Name, then that layer is only a category title for all the layers
nested within. A server that advertises a Layer containing a Name
element shall be able to accept that Name as the value of LAYERS
argument in a GetMap request and return the corresponding map. A client
shall not attempt to request a layer that has a Title but no Name."

IMHO this means you can ommit the  but have to provide the
. And if the layer has no name it can simply not be requested in
a GetMap-Request. If I change the code like above I have to provide a
"wms_name" in the METADATA part of the MAP file to make the layer
queryable. If I ommit "wms_name" then the layer get's no  and can
therefore not be requested by the client. IMHO it's then up to the
server whether or not to render that layer which is exactly what I want.
For overviews I want multiple layers where only one is active for a
given scale but which one is up to the server. Therefore a client should
not be able to explicitly request one of them. Instead I group those
layers in a named layer by a GROUP clause.

So please check this out. May be we should file a bug report on that.
But I think someone else should confirm this...

[mapserver-users] Font sizing problem in MS 5 (with inline feature)

[Doyon, Jean-Francois]

G'day,

Still on the path to upgrade to MS 5 and a couple of problems left ...

The one that preoccupies me right now is the fact that I have a truetype label 
that won't size properly.

The layer is defined as:

LAYER
NAME "northarrow"
STATUS OFF
TYPE ANNOTATION
LABELCACHE OFF
MINSCALE 0
MAXSCALE 500.1
TRANSFORM FALSE
GROUP north_arrow
METADATA
"checkable""0"
"legend_order""-1"
"LEGEND_GROUP" "base"
END
FEATURE
POINTS 40 40 END
TEXT "+"
END
CLASS
LABEL
COLOR 0 0 0
TYPE truetype
FONT esri_1
SIZE 65
FORCE TRUE
OUTLINECOLOR 255 255 255
  END
END
  END

This puts a north arrow in the top left corner of the map image.  The LABEL 
ANGLE is set dynamically via URL.  I don't recall exactly why we used a label 
instead of a symbol, but there must've been a good reason ...

An example in MS 4.8.1 can be viewed here:

http://atlas.nrcan.gc.ca/site/english/maps/topo/map?mapsize=428+380&scale=500.00&mapxy=1516867.58194739+-209769.54479788843&mode=zoomin&layers=north_arrow%20other_features%20million_grid%20t50k_grid%20grid_50k_3%20roads%20hydrography%20boundary%20builtup%20vegetation%20populated_places%20railway%20power_network%20manmade_features%20designated_areas%20water_features%20water_saturated_soils%20relief%20contours%20toponymy%20contour%20nodata_ntdb_50k

In MS 5, the "label" appears incredibly small (I can barely make out it's 
shape, it's a few pixels big), and playing with SIZE seems to do nothing at 
all.  I've changed the TEXT value, and the label seems to change shape but 
still no change in size.

Anyone know what's going on?  I didn't see any documented changes that look 
like they should affect this ...

Thanks,

You can't. OSM uses "Google" style tile indexes, OpenAerialMap has

the answer is "patch GDAL".

You can't. OSM uses "Google" style tile indexes, OpenAerialMap has
support for "TMS" style tile indexes. GDAL only supports the latter. So
the answer is "patch GDAL".

[mapserver-users] Mapserver and Microsoft SQL Server 2008

[perfectmind]

Hi

I'm looking for a way to switch our current postgre setup to SQL Server
2008. I can get the map data into SQL I just need a way to tell mapserver
(in the mapfile) to look at the SQL 2008 database.

I found a post relating to a plugin in order to do this:

PLUGIN "C:\ms4w\plugins\msplugin_mssql2008.dll"

http://mapserver.gis.umn.edu/development/rfc/ms-rfc-38

But i cannot find the dll anywhere, does it exist, if not when will it be
released?

Any additional help would be appreciated.
Thanks
Chris

Re: [mapserver-users] tile server

[Milo van der Linden]

Hello All,

I recovered the post where I found how remote tiles from a WMS-C cache 
are supported here:

http://wiki.openaerialmap.org/Using_With_MapServer

Now, what I want to use this structure for is to get OpenStreetMap maps 
served as layers in my mapserver. OpenStreetMap uses mapnik to serve the 
tile layers, they are accessed in the form:


http://tile.openstreetmap.org/7/63/42.png

How would an xml file be set up to serve this as a layer?

Main purpose is to expand the usability of openstreetmap into the 
desktop-GIS world by using mapserver as intermediate WMS server.

Hello list,

a little while ago I read somewhere that it is possible to connect a
tileserver via a virtual layer to mapserver. The trick was to store an
xml file and create a layer definition in the mapfile that pointed to
the tile server with information about the tilesize, zoomlevels and so on.

I can't seem to find it anymore...

Can anyone point me to a succesfull tileserver connection sample?

I don't mean running mapserver as tileserver, but attaching a layer from
a tileserver.

Kind regards,

Milo

although this is a nice approach, I can't go with Python. We need a high
performance WMS and I believe that the snake can not fulfill our
expectations. Well, in the meantime I patched the MapServer code a
little bit and made it being an Apache module, reading and parsing the
map file only once on startup. This is much faster than the good old CGI
and seems to work fine...

In an earlier mail in this thread I stated that IMHO there's a problem
with the MapServer code. I modified the stated things and now it does
the same thing: only giving a  if 'ows_title' metadata is given.

Well, another annoying thing which is resolved by the module solution.
Now the Apache setup is something like:

 
   SetHandler "wms"
   WMS_Map "/srv/wms/wms.map"
 

resulting in a simple URI like
http://localhost/wms?service=WMS&request=GetCapabilities. So with little
work I solved three issues for me: speed, URI niceness and overview
layer grouping. Well, several nice ideas came to daylight but I will go
with mine.

Thanks to you and all helpers involved.
