Steve,
Thanks for the reply. To clarify, I am using 5.2. I'm guessing by what
you're saying is that bugs with a new feature like this are to be
expected - I just wanted to check if it was already known to anyone else
before submitting a ticket in the trac.
Regards,
Mike

Support for tile names relative to the tile index is brand new in 5.2 so in
older versions
absolute paths or paths relative to the mapfile were your only options.

Ok...I figured out the problem pretty much right after I clicked send on
that last message. I had generated my tile index.shp with relative
paths for the LOCATION field (i.e., relative to the shp file). I just
regenerated it with absolute path names, and it the query function works
fine.
So would this be a known bug of any sort, or is it just bad practice to
use relative filenames with MapServer?

Hello list,
I'm sure this one has come up before, but I can't seem to figure out
what I need to do. I have some tiled raster layers that I've got in a
mapfile that is being used for generating ka-map tiles. I'm trying to
query the values on these layer using the queryByPoint function in
php_mapscript. I have a generic identify function that returns results
for any of my vector layers, and for non-tiled raster layers - just not
for the tiled raster layers. Is it possible to query tiled raster
layers? If so, can someone spot what I'm doing wrong below?
The tiled-raster layers in the mapfile generally look like this:
LAYER
NAME "Tiled Raster"
GROUP "Tiled Raster"
STATUS ON
TYPE RASTER
TILEINDEX "/data/index.shp"
TILEITEM "LOCATION"
METADATA
"imageformat" "AGG_JPEG"
END
PROJECTION
"init=epsg:4326"
END
END
And here is the function in PHP:
public function Identify($oMap,$layer,$x,$y,$cellSize)
{
$oLayer = $oMap->getLayerByName($layer);
if (in_array($oLayer->type,
array(MS_LAYER_POINT,MS_LAYER_LINE,MS_LAYER_POLYGON)))
{
$oLayer->set("toleranceunits",$oMap->units);
$oLayer->set("tolerance",$cellSize*3);
}
else
{
$oLayer->set("tolerance",0);
}
$oLayer->set("template","dummy.html");
$oQPoint = ms_newPointObj();
$oQPoint->setXY($x,$y);
$aResults = array();
if (@$oLayer->queryByPoint($oQPoint,MS_MULTIPLE,$oLayer->tolerance) ==
MS_SUCCESS)
{
$oLayer->open();
$nResults = $oLayer->getNumResults();
for ($i=0;$i<$nResults;$i++)
{
$oResult = $oLayer->getResult($i);
$oShape = $oLayer->getShape($oResult->tileindex,
$oResult->shapeindex);
$aResults[] = array($oResult,$oShape);
}
}
return $aResults;
}
Thanks in advance for any help,
Mike
