Spectrum Spatial (SSA/LIM)

Is it possible to create a thematic grid that is automatically kept up to date when the underlying data changes? I can make this work with other types of thematic layers but not grids.

What are you mapping Krister?

Is it just a count of points within a grid cell or perhaps totals or averages of values?

You are correct that the heatmap does not dynamically change with the data.

It is a point layer where I want to show the averages of values. So if it's not possible with an ordinary grid I guess I will have to create an extension that uses the mapping service to generate the map on the fly.

I would consider generating a vector grid of squares covering your area of interest and then create a ranged thematic map. Particularly if the data is changing regularly and you want to monitor that change.

I ended up using an extension that adds a layer directly to OpenLayers and use the mapping service to render the heat map. This keeps the heat map up to date.
