[FIX] GeoTools and GeoServer ( < 2.1.4) not able to load raster plugins with latest Tomcat

Blog ‐ Posted on 12.05.2010 by simone giannecchini

The ProblemLately some GeoTools and GeoServer ( < 2.1.4) users reported issues related to GeoTools raster plugins not being properly loaded in Tomcat 6.0.24 and above.Typical scenario is as follows: Geoserver deployed in Tomcat 6.0.26 along with the GDAL ImageIO-Ext extensions. The available GDAL formats properly appear in the Store user interface but, when trying to configure a new coverage, an error is reported and the logs shows the following messageCaused by: java.lang.IllegalArgumentException: Incorrect input type! at javax.imageio.ImageReader.setInput(ImageReader.java:290) at it.geosolutions.imageio.gdalframework.GDALImageReader.setInput(GDALImageReader.java:838)The causeBehind the scenes this is what is happening:In latest Tomcat releases a huge amount of work has been put in...

BigTiff support in GeoTools/GeoServer (Alpha testers needed)

Blog ‐ Posted on 21.04.2010 by simone giannecchini

Dear all, at GeoSolutions we have recently worked on support for the BigTiff format, which basically consists of an extension of the Tiff format to support raster larger than 4 Gigs. Work is based on an ImageIO plugin for the ImageIO-Ext project, but this will be incorporated into GeoTools and GeoServer.Long story short, we are looking for alpha testers, since the impact of the change is rather large for the tiff reader/writer, therefore we would like to have as much feedback/testing as possible prior to port this work to GeoTools/GeoServer. If you are interested in helping us with testing with...

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...
