I want to use GeoServer WMS server for custom styling. Let's say I have an area as polygon in a shapefile, but I don't have this area's temperature as an attribute. From a web service I gather temperature points inside that area. Now I want GeoServer to color this area according to these dynamic temperature points.
Here is an example:
If it is possible, I even want to place these borders on image and some explanations about colors on right side. How can I send these temperature points to a GeoServer WMS. And can I do some custom coloring according to these dynamic parameters?
I don't know how to convert these point data to area colors.
My next question is similar but without points, can I colorize a polygon with dynamic attributes which isn't on the shapefile.
Here is an example I want to colorize these polygons according to their product type, but as earlier question, these product types are gathered dynamically.
I hope these are possible.
