Hi Thomas, After many attempts using the same expression syntax it finally worked. Is there any reason as to why the following expression syntax didn’t work the first time?
.layer.part CLASSITEM "class" .style.part CLASS EXPRESSION "0" I also needed to map the following attributes which all displayed the first time with no problems EXPRESSION "-1" EXPRESSION "1" EXPRESSION "2" Regards, Inna Nogeste | Spatial Information Specialist Geospatial Data and Services Information Systems and Services Division Bureau of Meteorology From: thomas bonfort [mailto:[email protected]] Sent: Friday, 1 April 2016 8:26 PM To: Inna Nogeste Cc: [email protected] Subject: Re: [mapserver-users] Shapefile features = 0 (zero integer value) are empty and ignored? [SEC=UNCLASSIFIED] What expression syntax are you using in your mapfile to select/filter these features? -- Thomas On 1 April 2016 at 02:40, Inna Nogeste <[email protected]<mailto:[email protected]>> wrote: I'm using MapServer 6.4 and have a shapefile where features have an attribute = 0 (zero integer value). I want to display these features = 0 but they seem to be regarded as null/empty features in MapServer so are ignored and won’t display on the map. Other integer values in the same field can be displayed on the map, including the value of -1, but not 0. I can select these records = 0 in ArcGIS and QGIS 2.8.2 Can anyone tell me how, or if, shapefile features with attribute = 0 integer value can be used in a MapServer expression, or how to enter values = 0 in to a shapefile for MapServer Expressions?
