<p class="MsoNormal">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.<br>
<br>
Other integer values in the same field can be displayed on the map, including the value of -1, but not 0.<br>
I can select these records = 0 in ArcGIS and QGIS 2.8.2<br>
<br>
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?<br>
