Mapscript Rasterquery returns empty result<BR></FONT><BR></DIV>
<DIV></DIV>Hi Frank, Alexander,<BR><BR>Again thanks for your reply; I've been
abroad for a month and haven't had time to check it out. However, I've ben
doing some work on it today, and tested the following:<BR><BR>I made a test
tiff, with 2 large areas surrounded by NoData. When clicking anywhere in any
one of the 2 big areas I get the response:<BR><CODE
class="wrappedText focusRow" role="listitem"><BR>{"_handle_":Resource id
#47,"numlines":1,"type":0,"index":-1,"tileindex"</CODE><CODE
class="wrappedText focusRow"
role="listitem">:-1,"classindex":0,"numvalues":8,"text":"","bounds":{"_handle_":Resource
id #48,"minx":401265.0032,"miny"</CODE><CODE
class="wrappedText focusRow"
role="listitem">:633815.31,"maxx":401265.0032,"maxy":633815.31},"values":[null,null,null,null,null,null,null,null]}<BR></CODE><BR>When
I click on any nodata area the response is <PRE role="list">Warning: [MapServer Error]: msQueryByPoint(): No matching record(s) found. in C:\ms4w\apps\fusion\MapServer\php\GetRasterPoint.php on line 36<BR>
Fatal error: [MapServer Error]: msRASTERLayerGetShape(): Out of range shape index requested. Requested 0 but only 0 shapes available. in C:\ms4w\apps\fusion\MapServer\php\GetRasterPoint.php on line 42<BR>
<BR>
<SPAN style="FONT-FAMILY: Arial">This behaviour follows the edges of the areas perfectly. Also I checked it out with fixed coord pairs, and it doesn't seem te related to CRS problems. I've also tried IMG instead of TIFF, but no difference there.<BR>
<BR>
As mentioned, I'm running mapscript 5.2.1, not 5.6. I'm don't know if this would make a difference, but perhaps someone could test this for me? <BR>
<BR>
The TIFF I use for testing is available from: </SPAN><STYLE>BODY {

things):<BR> EXTENT -1000000 -1200000 2902206

with Alexander that you should be carefully reviewing your<BR>input
coordinate and insuring it is in the same coordinate system<BR>as the raster
file. The returned values are expected if you are<BR>attempting to fetch a
non-existant result shape.<BR><BR>If you simplify your test case down as
much as you can and you still<BR>can't figure out why you do not get a
result then you could try to<BR>bundle this up and submit it as a ticket.
Keep in mind that such a<BR>ticket is much more likely to be acted on if you
make it *easy* for<BR>the developer to reproduce your problem.<BR><BR>Best
