heatmap
Description
Adds heatmap functionality to layers configured to support it (WMS-layers only at the moment). Configuration is done by adding the following information to a layers JSON:
{
attributes : {
geometryProperty : "the_geom",
layerWorkspace : "ows",
heatmap : ["properties to use", "as heatmap weighted property"]
}
}SelectedLayers bundle will show heatmap-enabled layers with an additional "Heatmap" tool in the layer frame to access the functionality. Note! Generated SLD expects Geoserver as the WMS-service.
