Re: [Geoserver-users] How to pass parameters to Geoserver Heatmap SLD

That's great explanation Nikolai. Thank you very much for all help. I have a shapefile with polygons. I want to generate Choropleth map. Whatever geoserver SLD examples I saw , uses static filtering from SLD only. Is it possible to create Choropleth maps using SLD like this heatmap SLD? -- Vi

Thank you Nikolai. It is working. I am testing it and if you can guide me in this matter also. Nikolai Bock wrote > > > > > weightAttr > > > > > > weightAttr > > > > population > >

Yes Andrea, It is a map of the cities in California. It should be true. I haven't noticed that San Francisco and Los Angeles are the biggest concentration. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/How-to-pass-parameters-to-Geoserver-Heatmap-SLD-tp5061851p5062057.h

Also I think this SLD is not giving proper result. Please check out the image attached. Red dots are Points. But underlying heatmap is not as per weighted attribute. heatmap.png -- View this message in context: http://osgeo-or

NO, there is no changes in result by changes in output. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/How-to-pass-parameters-to-Geoserver-Heatmap-SLD-tp5061851p5061966.html Sent from the GeoServer - User mailing list archive at Nabble.com. ---

Re: [Geoserver-users] How to pass parameters to Geoserver Heatmap SLD

Yes I know we can define Default paramater in SLD. like you said, it will be used in case of ENV is not passed. Please have a look at below URL (this is URL with ENV parameter for layer overview of Geoserver). I hope it is correct but unfortunately it is not using 'population' parameter in result

Re: [Geoserver-users] How to pass parameters to Geoserver Heatmap SLD

Yes I know we can define parameter in SLD only. but this will be static. I have other attributes also in my table so on User selection Attribute-wise Heatmap. Thats why I need to pass 'env' parameter. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/How-to-pass-parameters-to

Re: [Geoserver-users] How to pass parameters to Geoserver Heatmap SLD

In that case also It is not giving any output. I am trying to pass parameter (env=) to directly URL. so now it is like : http://localhost:8081/geoserver/work/wms?service=WMS&version=1.1.0&request=GetMap&layers=work:cbsa_pop&*env=weightAttr:population*&styles=&bbox=-124.269371032715,32.545936584472

Hi I am trying to generate heatmap using Geoserver Transformation SLD (http://docs.geoserver.org/stable/en/user/styling/sld-extensions/rendering-transform.html#heatmap-generation) . as mentioned on the page, It requires few parameters: - data - weightAttr - radiusPixels - pixelsPerCell - outputBBO
