[Geoserver-users] gs: HeatMap "nonstandard"

GeoServer GeoServer User

Hi,

I would like to generate a heat map using the GeoServer’s gs: Heatmap (https://docs.geoserver.org/stable/en/developer/programming-guide/wps-services/implement-rendertrans.html)

However, by default, I saw that it generates the heatmap by agglomerating the points, however, I would like it to generate from a parameter (database field), for example, the price column of a land, presenting through the heat map, the places where land is most expensive.

Is it possible to do this with gs: Heatmap, if so, how?

I thank you for your attention,

Hi Fernando,

Depending on how the data is organized this may be possible. The HeatMap takes an optional weightAttr. Instead of having a value of “1” for each value, it would add up the price at each point. In some cases, maybe that’d be ok.

If not, you may have to figure out some way to rasterize the data and then style that raster?

Cheers,

Jim

Thanks Jim,

I’m going to do some tests!
