Developer corner: Compact choropleth map styles with the Categorize function

One common task in cartography making is setting up a choropleth map, that is, a map showing different shades of colors or patters for different categories of a statistical attribute, such as population.GeoServer example data directory ships with two such examples using an old USA states map having, among others, population count per state. The two following maps should be familar, the first is using the population style, the other the pophatch style:The original styles use a typical SLD 1.0 setup to build choropleth maps, that is, use rule filters to tell apart the categories.This is fine, but also quite...

Oceanographic Database, managing oceanographic data with GeoServer and GeoBatch

Dear All,in this post we'd like to introduce some work we have done recently at GeoSolutions towards an applications that is able to ingest in real-time, manage, visualize, retrieve and chart data acquired by oceanographic and meteorological sensors (like sensors mounted onboard underwater gliders as an instance) over time. We called this application, Oceanographic Database.The infrastructure we have put together is shown in the picture below.Summarising, we can identify the various components and their roles as follows:Data is ingested via GeoBatch in near real-time with proper prepocessingGeoServer is used in conjunction with some custom REST extensions for performinng visualization, dissemination and export to Google...

Developer’s Corner: GeoNetwork-Manager, super-simple Java client library for GeoNetwork

Dear All,we just wanted to spend a few words about a Java library we have just released under the MIT license for talking to the GeoNetwork Open Source Project. We have named this library GeoNetwork-Manager (once again, a lot of brainstorming behind that name, really...).Basically the goal of this library is to provide a simple yet usable way to interface a Java application with the GeoNetwork that would actually ease the work of the developers hiding away from them the relative complexity of theCSW protocol without introducing a complex communication layer. Here you have some basic facts about the library: minimum set of external...
