Hi GeoToolsers, So Jody has been prodding me to clean up the ColorBrewer module and friends, mainly Classification Functions. At the moment a ClassificationFunction obtains the FeatureCollection from a Feature, which is no longer possible.
What is being proposed is: ClassificationFunction.evaluate(featureCollection) --> Classification (actually i'd rather call this a classifier) + parameter specifying things like number of classes, attribute name SlotFunction evaluate(feature) --> slot # + parameters like Classification In line with the change from org.geotools.filter.Expression to org.opengis.filter.expression.Expression and org.geotools.filter.FunctionExpression to org.opengis.filter.expression.Function I will do a quick scour of the net to see if there are any standard naming for such classification functions, for the day that we support an expression like "Slot(EqualInterval(5, SPEED, ROADS))". Ian: GeoVista is likely the only other project with a vested interest in this... what are you currently using/expect to see? If anyone has any comments or would like to freak out, please do so now. Cheers, Cory. ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
