At GeoSolutions we believe that success stories about important organizations and Open Source Software should be openly shared and they can be used as a measure of OSS success in the formal enterprise environment (but you should alreay know this ;)). In this blog post we are going to quickly introduce some work we have done for the Fishery and Aqualture Department of the Food and Agriculture Organization (FAO) of the United Nations (UN).The FAO Fishery and Aqualture Department, specifically the FIGIS group; is involved in many efforts geared towards the conservation of the marine ecosystem and GeoSolutions is honored to work with them on some of the mapping applications they need...More
Developer’s Corner: GeoServer Stunning image quality + max compression rate = New PNG8 quantizer is served!
Hi everybody,in this blog we want to introduce the new GeoServer PNG8 quantizer.PNG8 is a shorthand for PNG 8bit, that is, a PNG image that uses a fixed palette of 256 (or less) colors and can thus encode each pixel with just one byte.The interest in the format comes from its smaller size, often between 2 and 3 times smaller than the equivalent 24bit PNG image. Smaller size means:proportional size cut in tile cache storage, which normally means cutting away several GB if not TB (depending on the amount of seending and the size of the cached geographic area)shorter transfer...More

Dear All,in this post we are going to briefly introduce the JPIP (JPEG 2000 Interactive Protocol) protocol, sharing part of the knowledge we have gained over the last years while working with this technology.The basicsThe JPIP protocol is defined in an ISO standard, specifically ISO/IEC 15444 part 9 drafted by the JPEG ISO committee. Such standard defines an interactive protocol that takes full advantage of JPEG 2000’s scalability properties by means of additional signaling JPIP in order to interactively deliver pieces of a JPEG 2000 image in essentially arbitrary order, in response to real-time application requests using potential very low...More
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...More
