Developers Corner: have your SLD transform raster data into vectors on the fly

Hi all,in this post we'd like to share our most recent endeavor in dynamic data rendering within the GeoServer and GeoTools open source projects.The problemSuppose you have a set of scientific raster data sets, maybe they represent some sort of concentration, elevation, or maybe they represent wind, currents, or some other vector phenomena via two bands (one for magnitude, one for direction).Now, you have lots of them and people want to display them in various ways. Raster with color scales are nice, but often you need to render them in other ways, such as contour lines, polygons catching all the...

Developers Corner: Improving GeoTools/GeoServer raster reprojection performance

Ciao a tutti,we hope everybody had nice seasonal holidays and is back fresh and ready to move on with another year of activity.In this blog we'd like to present some of the work we have been doing in recent time to improve GeoTools and GeoServer raster reprojection abilities. Raster reprojection is a quite heavy process in which every single pixel of the original image has to be mapped into a new position in the target raster. Here is a visual representation of a small set of pixels, before and after the reprojection (in this case, from WGS84 to polar stereographic):...

Developers Corner: Improving GeoServer security

Hi,during the last few weeks we have been thinking a lot about improving the GeoServer security, making it at the same time easier to integrate with external authorization systems and making it more expressive in terms of what kind of security rules can be expressed.As part of the work we have been re-evaluating how the security can be applied in an ever growing software like GeoServer without having to cripple the available service abilities or to have to run after the developers constantly adding new features to the system.The evaluation resulted in a (long-ish) comparison of the possible models, including...
