Here's some more information.... mapfile.map (excerpt): LAYER NAME "countries" STATUS OFF TYPE POLYGON CONNECTIONTYPE OGR CONNECTION "africa.geojson" DATA "select * from africa" CLASS STYLE OUTLINECOLOR "#ff0000" END END CLASS EXPRESSION ([value] >= 0 AND [value] <= 1000000) STYLE COLOR "#FFE397" END END END I have tried numerous types of select statement in the DATA definition, but have failed to influence the styling based on the ‘value’ property added to the geojson file. Of course, this may have all been in vain, if the GDAL driver does not support anything other than ‘select * from <layer>’, but I cannot tell from the documentation - MapServer, or GDAL - what is allowed. Here is an excerpt of the africa.geojson file, with the additional property ‘value’ added. Following is the output from ogrinfo. { "features": [ { "geometry": { "coordinates": [ [ [ [ 8.621624, 36.941797 ], [ 8.621624, 36.941797 ] ] ] ], "type": "MultiPolygon" }, "properties": { "cartodb_id": 1, "created_at": "2013-11-12T16:15:59+0100", "name": "Algeria", "updated_at": "2013-11-12T16:15:59+0100", "value": 10000 <<<<<<<<<<<<<<<<<<<<<<<<<<<< custom property }, "type": "Feature" } ], "type": "FeatureCollection" } chris:tmp chris$ ogrinfo -summary -al africa.geojson INFO: Open of `africa.geojson' using driver `GeoJSON' successful.
