RE: [mapserver-users] Shapefile, itemnquery and HTML image map generation problem
Hmm, based on your comments about extent below, I just noticed that if I expand the extents well outside the area of interest, it renders more of the missing areas! Not all of them though. So it does seem extent related. You were right that it seems to favor the areas on the very interior of the extents. Unfortunately I then get a map that is too zoomed-out to be usable.

RE: [mapserver-users] Shapefile, itemnquery and HTML image map generation problem
Yup, that was it. I had some crazy extents defined for the URL strings. Apparently the center of gravity of my URL extents combined with the map image size gave me the false impression in the rendered map image that I had the region covered. It showed the region of interest, but selected a small area for actual query. Thanks for the critical bit of insight Steve - extents.

If I reduce the query string to just one that does work:
http://localhost/cgi-bin/mapserv?map=/NWPL_CRREL/MLRA/mlra.mapqlayer=coe_m;
mode=itemnquerysearchmap=truelayer=statesmapext=-91+34+-89+49mapsize=600
+400qitem=MLRARSYMqstring=(%22[MLRARSYM]%22%20in%20%22105%22)
I get a map with jus the one MLRA (#105) in yellow.
If I select on that does not work (#112):
http://localhost/cgi-bin/mapserv?map=/NWPL_CRREL/MLRA/mlra.mapqlayer=coe_m;
mode=itemnquerysearchmap=truelayer=statesmapext=-91+34+-89+49mapsize=600
+400qitem=MLRARSYMqstring=(%22[MLRARSYM]%22%20in%20%22112%22)
I get this error in the browser:
msQueryByAttributes(): Search returned no results. No matching record(s)
found. msSearchDiskTree(): Search returned no results. Unable to open
spatial index for c:\shape\MLRA_42_low_res/mlra_v42.qix. In most cases you
can safely ignore this message, otherwise check file names and permissions
But 112 is clearly rendering in the CLASS of the LAYER.

I think the missing ones are from random places n the query string. I have
tried putting just one of the missing MLRA in the query string and it still
does not generate area
How do I label? (I am really new to MapServer!)

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?

Just add a querymap object to your mapfile, like so:
QUERYMAP
STATUS ON
END
Then change your URL to use the mode itemnquerymap and that should return
just an image with the
selected features highlighted in yellow.

RE: [mapserver-users] Shapefile, itemnquery and HTML image map generation problem
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 area 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? john From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of W.John Guineau Sent: Thursday, December 03, 2009 3:11 PM To: mapserver-users@lists.osgeo.org 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.
