Hi all, I am new to OpenLayers (so forgive me in advance).
I have a polygon layer in GeoServer (from a shapefile) consisting of 487 features and 15 statistical attributes of socio-economic variables. What I want to accomplish is to visualize these 15 variables in a web map service, where the user can select the variable he/she wants to visualize and that the color fill represents low to high on the selected variable (white to dark grey i.e.). So far I have managed to set up an OpenLayers page that reads the GeoServer layer, and outputs the attribute table below the map when I click one of the features. However, I am still lost as to how I should proceed to create the visualization. One example of an end-result could look similar to this: http://sedac.ciesin.columbia.edu/maps/client So my question is. What styling code am I looking for, and could this type of solution be created out of the one layer, or do I need one layer for each attribute? And if I need to create a rule based class interval, do I have to do this manually for each class, for each attribute? Any example code that points to the suggested direction would be great! thanks! Best, Andreas
