Automatic ImagePyramid import for GeoServer

Blog ‐ Posted on 12.03.2010 by simone giannecchini

Lately a new interesting feature has been added to the GeoServer, the possibility to automagically (yeah, it's not a typo) import raster pyramids created with gdal_retile and serve them as WMS/WCS layers.Andrea Aime has created a nice tutorial (see here), that should guide you through the basic steps for building a raster pyramid and then ingesting it into GeoServer.It is worth to point out that, to try this work out, you need to:Use a GeoServer nightly buildInstall the ImagePyramid extensionInstall fwtools or build GDAL on your platform of choice.Enjoy,Simone.

GeoServer and GeoTools now supporting JPEG2000 via Kakadu SDK

Blog ‐ Posted on 04.03.2010 by simone giannecchini

Back in December 2009 Ing. Daniele Romagnoli and Ing. Simone Giannecchini have worked on bringing to supported status the raster plugin for serving JPEG2000 files via the well-known Kakadu SDK in GeoTools and GeoServer. A detailed description of the feature provided can be found here.The rationale behind this work was to be able to exploit directly the Kakadu SDK without having to pass through the GDAL Java wrappers in order to achieve higher performance and robustness as well as to gain finer control over the steps we were taking in order to load raster data from JPEG2000 files.The plugin for...

Sharing thoughts about FOSS4G-IT 2010 part 1

Blog ‐ Posted on 26.02.2010 by simone giannecchini

Ciao a tutti,as announced in a previous post today we start to share the materials produced for the Foss4g-IT conference. Thanks to SUPSI, that in Lugano was host of this nice event, we had a very good time.In this first part we are sharing the slides of the presentation that Ing Simone Giannecchini, founder of GeoSolutions, illustrated at SUPSI’s Aula Magna.In this presentation you’ll find the state of art as far as Geoserver and its latest features are concerned: integrated security, dynamic symbolizers and ImageIO-Ext GDAL support. Also, quite interesting, it’s the use case describing an integrated system for scientific...

(FIX) GDAL extension not working with GeoServer’s Windows service wrapper

Blog ‐ Posted on 22.02.2010 by simone giannecchini

Today, we have investigated the issue reported by several users on the GeoServer's mailing list about being unable to get the GDAL-ImageI/O-Ext extension to work when GeoServer runs as a service on Windows.Deploying the GDAL ImageI/O-Ext native libraries in a location referred by the PATH environment variable (like, as an instance, your JDK/bin folder) allows GeoServer to successfully recognize them when invoked via the start.bat script. However, this does not seem to work when running GeoServer as a service on Windows. As a result, during the service startup, GeoServer log reports this worrysome message:it.geosolutions.imageio.gdalframework.GDALUtilities loadGDALWARNING: Native library load failed.java.lang.UnsatisfiedLinkError: no...

Geoserver continuous map wrapping!

Blog ‐ Posted on 19.02.2010 by simone giannecchini

Recently one of our clients has provided us with the funding to address an issue with the Geoserver rendering core module that was preventing us from drawing polygons crossing the dateline change, or, to put it another way, to be able to have maps that were wrapping like continuous wrapped maps from Google.Our specific use case is also quite challenging on its own since we need to use a projection in which the dateline change has been moved away from the usual -180/+180 by using a non standard central meridianThe result, prior to the work described here, does not look...
