Hi Steve. The missing data is not always clustered. It just happens on that 
map. 

I'll get you the map file and data tonight. I'm away from my pc now.

Seems like an extent problem to me - the way the results are clustered in the
center of the image. MapServer does apply a spatial pre-filter for attribute
queries. However, the searchmap=true should compute a proper extent based
on your image properties (extent, size) before doing the query.

John, what are the changes you could zip up your data and mapfile for me?

Do the ones not selected fall at the end of your qstring? I'm wondering if
something is getting truncated. I'd think

you'd get a parsing error in that case, but perhaps not. Can you label the
polygons with the value for MLRARSYM?

RE: [mapserver-users] Shapefile, itemnquery and HTML image map generation problem

Hi Dave, the missing id's seem randomly distributed spatially. There is no 
obvious pattern to the id's - they are of the form NNN or NNNL (where N is a 
number, L is  letter. I can even restrict the URL to a single (missing) id and 
it still does not emit the  tag, but does render the class layer in the 
image.

John,

What features are not being rendered?  Are they randomly distributed?  located 
at the outside edges of the rendered features? Any pattern to the IDs?

How would I go about debugging this?

I think this is GDAL and its query of shapefiles, right?

The bottom line is that MapServer finds all the items when it is rendering the 
map by layer/class EXPRESSION, but the qstring in a URL using the exact same 
EXPRESSION string misses some of the items.

I can also use ogrinfo from MAP4W to execute an SQL query directly on the 
shapefile and the items in questions are certainly there.

In the image below, the green areas are result of the mapfile layer class 
EXPRESSION - all are correctly rendered. However, several of them do not get 
generated (HTML imagemap  tags not generated) when using a URL and 
itemnquery/qstring with the identical EXPRESSION.

How do I enable debug (enabling mapfile DEBUG does not seem to give any useful 
info as to why GDAL is skipping certain items) Am I better off using MAP4W or 
similar to get debug/trace info for shapefile queries?

Subject: [mapserver-users] Shapefile, itemnquery and HTML image map generation 
problem

I have a basic vector shapefile that I am trying to generate HTML clickable 
maps from. It seems to work well for the most part, however there is a problem 
where some items from the shapefile do not get processed from the qstring in 
the browser, but they are processed fine in the mapfile layer (to color them 
differently).

So the map that renders shows all the items colored properly as the layer class 
defines. Using the exact same list of items in the HTTP query string causes 
several items to be ignored (the HTML image map area is not generated).

http://localhost/cgi-bin/mapserv?map=/NWPL_CRREL/MLRA/mlra.map&qlayer=coe_m&mode=itemnquery&searchmap=true&layer=states&mapext=-91+34+-89+49&mapsize=600+400&qitem=MLRARSYM&qstring=("[MLRARSYM]"%20in%20"102A,102B,102C,103,104,105,106,107A,107B,108A,108B,108C,108D,109,110,111A,111B,111C,111D,111E,112,113,114A,114B,115A,115B,115C")

Below is the layer section from the mapfile. I can post whatever else is 
helpful.

Thanks for any help on this.
