[mapserver-users] choosing region of interest using "referencemap"
hello I was wondering how I could choose region of interest using "referencemap" ? Could you give me a hint ? regards ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] Mapserver Templates
Hi Andrew: Cleaning out my email and I noticed this message received no love. It's probably because it's a bit vague. Depends what you mean by template. There aren't interface templates in the ArcGIS Server sense, primarily because MapServer doesn't cover the client-side of things. You'd need to look to the variety of client-side environments capable of using MapServer services (e.g. OpenLayers, GeoMoose, GeoExt, MapFish, pmapper, etc...) Layer templates for setting up OGC services can be found in the various how-to documents. MapServer supports templating for presentation of query results but I get the feeling that's not what you're after...

RE: [mapserver-users] Extreme data-driven Symbology with CGI mapserver
Hi Brent: Producing legends with bound styling is indeed problematic. MapServer has no way to know how many variations are possible and it doesn't cache those encountered in a map draw. Binding a class name might help but the binding is at the feature level and a class name would generally apply to a group of features. Still, it might provide a useful key for a hash of styles that could be rendered as a legend. Might be more interesting to be able to configure a file or URL-based SLD reference for a layer from within the mapfile. For example: LAYER NAME 'extreme-symbology' DATA ... CONNECTION ... SLD 'some flle' or 'some url' ... END Then you'd have some other sort of production process, either scheduled or live to build the SLD from your database. Just a thought. Yet another idea would be to take advantage of includes. We might consider allowing a URL-based include to get a snippet of mapfile content. Producing that text (e.g. all the classes, and styles) wouldn't require mapscript at all. An option that would work now would be to produce the include file through a scheduled process. Just write a small script to write that piece of a mapfile and schedule it to run at some interval. Nice and simple and no MapScript.

Re: [mapserver-users] Extreme data-driven Symbology with CGI mapserver
Steve, Many thanks for the thoughtful reply. I haven't looked at Mapserver's rendering logic yet, but as the CLASS NAME binding would only be relevant for MODE=LEGEND, perhaps there could be a separate bit of code developed for generating a data-driven legend. The use of the INCLUDE in the map file would be somewhat difficult. In my case the CLASS list varies per logged-in user so the file management might get convoluted. I love the URL-based SLD idea (can I have it tomorrow?). I'll have to read the doc on SLDs. Maybe it's because I've been working on GeoMoose's feature digitizing and reading OpenLayers posts about creating features via WFS, but I see a time when Mapserver's LAYER/CLASSS structure needs to be able to be generated from the data.

RE: [mapserver-users] php mapscript
This problem is due to the new single pass query in 5.6.
I have marked your code with what I am using.
Try these mods marked with "*":
@$datQuery = $query_layer->queryByRect($qRect);
//number of objects
$resnum = $query_layer->getNumResults(); echo "number of objects:
".$resnum."";
//if query success
if ($datQuery == MS_SUCCESS) {
// $query_layer->open(); // getShape($result->tileindex,$result->shapeindex);
// resultsGetShape is now the way to get the shape object
***
// note: change of order in arguments
$shpobj = $query_layer->resultsGetShape($result->shapeindex,
$result->tileindex);
//read attribute
$attr = $shpobj->values;
//write headline
echo '';
foreach($attr as $name=>$wert) {
echo ''.$name.'';
}
echo '';
//write datasets
for ($j=0; $j<$query_layer->getNumResults(); $j++) {
$result = $query_layer->getResult($j);
//$shpobj =
$query_layer->getShape($result->tileindex,$result->shapeindex);
// see note above
**
$shpobj = $query_layer->resultsGetShape($result->shapeindex,
$result->tileindex);
$ri = $result->tileindex;
$si = $result->shapeindex;
$attr = $shpobj->values;
echo '';
foreach($attr as $name=>$wert) {
echo ''.$wert.'';
}
echo '';
$shpobj->free();
}
// $query_layer->close(); // <';
} // end success
...

Alan,
thanks for the reply, I tried it with getFeature(), but there comes the same
error.
nextShape() works only after msWhichShapes and here I need a rectobj.
But I want to use the script for queryByShape and queryByAttributes too.
Why there comes no array in $attr = $shpobj->values; ?
Any idea?
Sven
