[mapserver-users] UMN + Postsgis, features skipped

[Carlos Ruiz]

Andreas,

First, try to run SELECT DISTINCT(type) FROM 
"av_mopublic"."land_cover_lcsurface" to ensure that all the 

types that you're classifying exists. I know this sounds silly but we must check 
if the type column contains 

all the types you're looking for.

When some features are missing, it means that the expression type doesn't exists 
and then, it's not 

rendered.

I've noticed that expressions are case sensitive, and sometimes, it doesn't 
works with special characters, 

maybe this could be happening too.

Cheers from México

Subject: [mapserver-users] UMN + Postsgis, features skipped

Hi all,

I have troubles with the UMN/Postgis combo. When I just draw the layer
with a single class, it draws fine, but as soon as I use classification
with an EXPRESSION (simple string comparison), a lot of features are
skipped.

Attached I am sending a mapfile with just one class (buildings from a
landcover table). Most buildings are skipped, only a few are drawn.

I have no idea why.

The same table draws fine without problems in QGIS.

Any idea why the classification is skipping many features?

Thanks a lot,
Andreas
