Dynamic WMS styling with GeoServer: SLD and library mode

Hi all,today I want to delve a bit in the dynamic styling abilities that GeoServer provides.GeoServer fully supports a client's ability to specify a custom SLD 1.0 style instead of a built-in named style, this can be done in different ways:adding a reference to a internet accessible sld file via the &sld=url parameterspecifying the full SLD, url-encoded, in the request URL via the SLD_BODY=fullStyleDefinitionHere parameter POST-ing a GetMap XML document, as defined by the SLD 1.0 spec POST-ing the usual GET request, where each KVP parameter is sent over as a form parameter (this is a GeoServer extension)Let's have a...

Saving the world one application at a time: Atlas of Tuna and Billfish Catches

This blog post covers some work we have done to support the FAO Fishery and Acqualture Department, specifically the FIGIS group with information dissemination about catches of Tuna and Billfish over the last 60 years globally. As stated on their website:"... the Atlas presents the global distribution of catches by gear from 1950 to 2010, at 5° latitude by 5° longitude resolution, of those tuna and tuna-like species for which this distribution is generally well known on the global scale. These species consist of the so-called principal market tunas and some billfishes."Using Geoserver, OpenLayers and Ext-JS, we built for them a simplfied viewer that allow users to access dynamically their statistics and...

Developer’s Corner: Authenticating dummy clients in GeoServer

In this blog post we'll introduce a simple authentication method we developed for GeoServer that allows to deal with security unaware clients.GeoServer can be configured to force a user to authenticate, either directly when trying to access the capabilities document (challenge mode) or when trying to access a protected resource (mixed mode). GeoServer will send a "http basic authentication" challenge, that will force browsers to show up the "username/password" authentication dialog, and make other desktop application ask and send over the user credentials.There are surely more secure means to authenticate a user, yet basic http authentication is the minimum common...
