Ciao Madhuri,
I guess you are referring to WMS cascading.
That is available only on 2.1.x aka trunk. You can grab a nightly
build and test it.

Ciao,
Simone.

Hi Ciao,
Thanks for replying.
I have developed map for a city. I want to add world map as a base layer to
the map I have developed. how can I do this?

Thanks,
Madhuri

Hello,
I guess you must be using Open Layers.
For making the layer as a base use the following in your open layer code
  var political = new OpenLayers.Layer.WMS("layer name",
            "http://demo.opengeo.org/geoserver/wms&quot;,
            {'layers': 'layer name', transparent: true, format:
'image/gif'},
            {isBaseLayer: true}.

Hope this may help you

Hi

I am just starting to look at GeoWebCache (I'm with Geoserver-2.0.2) and see from the documentation that you can use Parameter Filters to handle CQL filters set by the client - which is just what I need. But the documentation is incomplete and refers the reader to the comprehensive configuration example and the XSD documentation. The configuration example also says TODO and there are no details. I cannot find relevant XSD documentation. Could anyone kindly give me some pointers?

Many thanks

Alan Hale

Many thanks Arne

So, if I understand correctly, I have to construct my own geowebcache.xml which will include details of any layer for which I wish to call GWC, and place under data_dir/gwc/.

Can I assume that (in <floatParameterFilter>) the <values> entries are optional? My values can be any one of over 6000 decimal numbers. In fact, am I expecting too much of GWC to cope with this in any case?

Yes, you'll have to construct a configuration file. Make sure you give layers new names, otherwise you'll have a hard time finding errors.

If you want a wildcard filter you should use the regular expression filter, and set it up for the types of numbers your backend supports.

Note that GWC currently provides no facilities for seeding or removing tiles that use such filters.

Thank you Arne

I'm not sure I understand the second point. My filter looks like this: "specid=x" where x is a decimal value from one of over 6000 possibilities. They are all of the same format. I assume "specid" is entered within the <key> element tags.

The key is correct. The floatParameterFilter tries to avoid duplicates, but in order to do so it needs to know all the possible values*.

A regexParameterFilter just treats the numbers as a text, and matches it againt a pattern. So it doesn't need to know the 6000 values in advance.

-Arne

*: If you code, you know how you never compare floating point numbers directly, you just check that the difference is sufficiently small? This is the same idea.

I'm still having trouble with this, so testing out with a simpler dataset. I can get the unfiltered data to display,but I can't get the filter to work.

This is the layer definition in my OpenLayers init() function:

var sppfilter = "taxa_taxon_list_id=3";
   // create WMS tetrads layer - individual species can be filtered on
   var wmstetrads = new OpenLayers.Layer.WMS(
            "Tetrads",
             "http://www.alanhale.co.uk:8080/geoserver/gwc/service/wms&quot;,
            {'layers': 'indicia_test:detail_occurrences', 'CQL_FILTER':sppfilter,'format':'image/png', 'transparent':'true'},
            {'opacity': 0.6, 'isBaseLayer': false, 'visibility': true}
       );

And here is my parameterFilter in geowebcache.xml:

<parameterFilters>
<regexParameterFilter>
<key>taxa_taxon_list_id</key>
<defaultValue>1</defaultValue>
<regex>^(.+)$</regex>
</regexParameterFilter>
</parameterFilters>

Grateful for any further guidance

The key is CQL_FILTER in this case, "taxa_taxon_list_id=3" is the value (after URL encoding).

Check, using Firebug or something similar, that it is indeed sent as uppercase to the server.

A regexParameterFilter just treats the numbers as a text, and matches
it againt a pattern. So it doesn't need to know the 6000 values in
advance.

This is the same idea.

I'm not sure I understand the second point. My filter looks like this:
"specid=x" where x is a decimal value from one of over 6000
possibilities. They are all of the same format. I assume "specid" is
entered within the<key> element tags.

Yes, you'll have to construct a configuration file. Make sure you give
layers new names, otherwise you'll have a hard time finding errors.

If you want a wildcard filter you should use the regular expression
filter, and set it up for the types of numbers your backend supports.

Note that GWC currently provides no facilities for seeding or removing
tiles that use such filters.

So, if I understand correctly, I have to construct my own
geowebcache.xml which will include details of any layer for which I
wish
to call GWC, and place under data_dir/gwc/.

Can I assume that (in<floatParameterFilter>) the<values> entries are
optional? My values can be any one of over 6000 decimal numbers. In
fact, am I expecting too much of GWC to cope with this in any case?

Hi

I am just starting to look at GeoWebCache (I'm with
Geoserver-2.0.2) and
see from the documentation that you can use Parameter Filters to
handle
CQL filters set by the client - which is just what I need. But the
documentation is incomplete and refers the reader to the
comprehensive
configuration example and the XSD documentation. The configuration
example also says TODO and there are no details. I cannot find
relevant
XSD documentation. Could anyone kindly give me some pointers?

Many thanks

Thanks Arne

So, I have changed geowebcache.xml to look like this:

<parameterFilters>
<regexParameterFilter>
<key>CQL_FILTER</key>
<defaultValue>taxa_taxon_list_id=1</defaultValue>
<regex>^(.+)$</regex>
</regexParameterFilter>
</parameterFilters>

and the request looks like this:

http://www.alanhale.co.uk:8080/geoserver/gwc/service/wms?LAYERS=indicia_test%3Adetail_occurrences&CQL_FILTER=taxa_taxon_list_id%3D3&FORMAT=image%2Fpng&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A900913&BBOX=-747655.7288,6443946.7458,-434569.661,6757032.8136&WIDTH=256&HEIGHT=256

But the filter does not work. I guess I am missing something obvious.

Alan

The key is CQL_FILTER in this case, "taxa_taxon_list_id=3" is the value (after URL encoding).

Check, using Firebug or something similar, that it is indeed sent as uppercase to the server.

I'm still having trouble with this, so testing out with a simpler
dataset. I can get the unfiltered data to display,but I can't get the
filter to work.

This is the layer definition in my OpenLayers init() function:

var sppfilter = "taxa_taxon_list_id=3";
    // create WMS tetrads layer - individual species can be filtered on
    var wmstetrads = new OpenLayers.Layer.WMS(
             "Tetrads",
