Dear all,We would like to take the occasion to introduce the ImageI/O-Ext 1.1.4 releaseVarious improvements have been implemented:Better GDAL Driver availability checks.Better TIFF-Metadata management (Tile ByteCounts and Offsets aren't stored into IIOMetadata node textual attributes anymore)Minor Improvements on Kakadu based JP2K writerMore work is coming to further improve support for large GeoTiff and BigTiff, so stay tuned for more performance in the near future for GeoTools and GeoServer.Artifacts for Imageio-Ext have been deployed on the GeoSolutions maven repository, as well as on the OSGEO one.The GeoSolutions team,More
Hi all,in this blog we're going to introduce the new GeoServer/GeoTools support for high accuracy datum transformation and projection control in general.Starting with release 2.2-beta2 GeoServer has support for grid based transformations, in particular NTv2 and NADCON grids. The grid allow for centimeter accurate transformations between datums, which is much better than the usual 7 parameters transformation supported so far by GeoServer, which included a few meters error.The reason for this difference is simple, the 7 parameters transformation is a simple roto-translation in 3D space, plus scaling, whilst the grid is a point to point mapping between position in the...More
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
