On May 20th 2011 we are proud to announce that Geopublisher and AtlasStyler 1.7 have been released.
Geopublisher is a tool for geographers to create and publish maps without any knowledge of HTML, SLD, webservers etc. and AtlasStyler is a
... [More]
graphical interface to create OGC SLD/SE documents without the need of hacking any XML.
GP and AtlasStyler applications are translated into five languages: English, German, French, Turkish, Italian and Russian. In this release not all translations are updated. Translaters are asked to translate any new strings to we can make a full translated 1.7.1 release soon.
It has been half a year since version 1.6 has been released and we are very sorry for the delay - usually we want to make four releases a year. The following points mark some of the most important new features in this new version.
Geopublisher:
Automatic on-line publishing on geopublishing.org:
When exporting an atlas you may choose to publish your atlas on-line at http://atlas.geopublishing.org automatically without any technical setup. You may also choose to protect your atlas with a password. This new hosting feature is a free service for everybody without any guarante. For users wanting commercial support please contact us.
New HTML editor:
Thanks to the Glowa Jordan River project we have been able to include a new HTML editor into the Geopublisher application. The new editor provides spelling correction for more than 20 languages and has many new features like importing Microsoft Word layout.
Rewrite of the "Personalize logos and icons" dialog. The new dialog can be found at Atlas -> Personalize Images. The user may now also define where on the map the maplogo should appear:
Support for languages, that are not official ISO languages. This extension was sponsored by the www.cuvewaters.net project which does research in Central-Northern Namibia.
>90% Turkish translation thanks to Alişan Balkoca, PROGIS Yazılım
Filter by search-word simplifies managing many entries in your data-pool or map-pool:
AtlasStyler 1.7 SLD/SE Editor:
AtlasStyler is an integrated part of Geopublisher which can be used as a stand-alone application. Most of these new features are also part of Geopublisher 1.7:
New concept of "RulesLists"
We introduced a new concept called RulesLists to allow the creation and management of very complex styles without losing the overview.
A "RulesList" is a collection of SLD Rules that belong together semantically. For example a quantile classification is presented in SymbologyEncoding as multiple <sld:Rules>. For the AtlasStyler user these are presented as one RulesList. You may define multiple RulesLists in one style and define CQL filters or Min-/Max-Scales for each of them. Btw: You can copy any RulesList directly to the clipboard as a set of <sld:Rule> tags.
Scale-dependency
Every RulesList in AtlasStyler can now be limited to a specific scale range. To change the symbology while zooming into the map just define two RulesLists with different Min-/Max-Scales.
This screenshot shows the new RulesList menu structure in AtlasStyler. Note that the GPS points are not labeled since the preview is zoomed out of the Max-Scale range for the labels. This is indicated by marking the "max-scale" column red. Also note that you can avoid entering any Min-/Max-Scale numbers manually by using the right-mouse context menu:
Support for styling raster:
Support to style one-band raster files (e.g. GeoTiff or ArcASCII). Two types of RuleLists are supported: "colors for distinct raster values" and "define value ranges to be painted in different colors". Both dialogs allow the definition of NODATA values which are mapped to transparency. Of course the raster styler also has support for scale-dependency and comes with all of ColorBrewers palettes included.
A small new feature is to convert raster color palettes extracted by gdal to SLD: See this earlier blog for a description.
Improved WFS compatibility:
We had a hackfest with Andreas Schmitz and Markus Schneider of the deegree 3 development team to test and improve compatibility. We are happy that it now works to create SLDs with AtlasStyler using a deegree 3 WFS as a feature source:
Under the hood:
New icons for the webpage and JavaWebStart making it clearer whether you are using a stable or testing release.
geopublishing.org moved to a faster server
As always we are very happy to hear from you. If you have any questions, bug-reports or ideas contact us via the mailinglist. [Less]

Currently, many different raster file formats exist. Some of them can store information about how to present the values stored in file. The GeoTiff format for example can include information on how to visualize the raster values.
One
... [More]
widely-used way to describe such colorization-information are color-palettes. Color palettes typically contain up to 255 mappings of raster-values to RGB color values.
The great gdalinfo command line tool is able to show such color palette information from any supported raster file format. Let's see how gdalinfo could be used to show such information:
gdalinfo C:\some.tif
...
Band 1 Block=256x256 Type=Byte, ColorInterp=Palette
Overviews: 2397x2103, 1199x1052, 600x526
Color Table (RGB with 256 entries)
0: 216,240,224,255
1: 32,104,48,255
2: 208,240,224,255
3: 200,224,208,255
4: 192,224,200,255
5: 184,216,200,255
6: 208,232,216,255
7: 48,112,64,255
8: 168,208,176,255
9: 40,104,56,255
...
If ColorInterp=Palette is reported by gdalinfo, a list of raster-value to color mappings follows.
Since version 1.7 AtlasStyler SLD/SE editor has support for raster files. When creating a style for a raster file, styling information is not automatically imported - unless it is already stored in a .sld file.
But recently there is a new function to import the output of gdalinfo for color palettes. Let's see how it works:
Last you would click the "Show XML code" or "Export all Layers as SLD". Since some time AtlasStyler is validating every SLD file automatically before saving: The resulting file can then be used with any WMS suporting SLD/SE, for example Geoserver.
Why would you want to do that?
Personally I have two typical usecases for this workflow:
1. Control transparency:
By converting the internal color-palette of a raster file to a SLD, it is easier to define transparency values. In the explame above, one would just delete a specific row, and the corresponding pixels are automatically transparent.
2. Save diskspace:
If you like to reduce the filesize of a RGB raster image, it can be very promosing to convert the three-band RGB image to a single-band image with a color palette - using gdal's rgb2pct tool. This conversion of course reduces the image quality (since the resulting image contains max. 255 colors), but also significantly reduces the disk usage. After this procedure I often need to control the transparency of the new file, resulting in reason 1. [Less]

l'Environnement / كتابة الدولة الـمكلفة بالـماء والبيئة (Morocco) attended several "train-the-trainers" sessions for Geopublisher in Bonn, Germany.
During the year 2010, they gave several courses about the publication of maps with Geopublisher in local institutions, like Ecole Doctorale Pluridisciplinaire, CIFRED and other graduate schools and faculties (FSA, FAST/CIPMA) of Université d’Abomey-Calavi (Benin) or the Université Ibn Zohr (Morocco). More courses are already planned for 2011.
The courses explained the general idea of multi-language publishing of maps on DVDs and the Internet, and every student created his own atlas with geo-data from the digital IMPETUS Atlas. Topics were:
Create a multi-language atlas
Add Shapefiles, Rasterimages and PDFs to you atlas
Define maps using the pool of data
Style maps (AtlasStyler) and describe layers and maps in each language
Export the atlas
The Geopublisher development team got a lot of valuable feedback and feature-requests, which were gradually realized in new versions of Geopublisher. Ask on the Geopublishing mailinglist or contact wikisquare.de if you are interested in tranings for your project or staff.

On November 8th 2010 we are proud to announce that Geopublisher and AtlasStyler 1.6 have been released:
The following points mark some of the most important new features in version 1.6:
Geopublisher:
Automatic correction
... [More]
of DBF attribute names which do not comply to the standards. This avoids a lot of problems when running the atlas on different/international computer systems.
It is now possible to define text labeling classes for each language. This allows e.g. to use one attribute for labeling in Arabic, and another attribute when the atlas is switched to English.
Exported atlases smaller
Atlases export with Geopublisher for distribution on disk (DVD, CD etc.) are now ~10Mb smaller.
A Geopublisher user may now switch the GUI/software language independently of the language the atlas data is shown in. So you can keep Geopublisher application in English while you look at the atlas in French.
Support for rasters has been improved. GeoTiff stays the preferred raster format. GP and its atlases now support prescaled overviews (pyramids) contained in the GeoTiff (see: gdaladdo) and generally uses less memory while displaying them.
A new tab 'Usage' has been added, to show you exactly where a layer is used.
Ability to automatically create a ZIP file of an exported DISK atlases.
Raster SLD transparency: The raster SLD editor contained in Geopublisher now allows to define the opacity of a color map entry. This makes it easier to define transparent colors for one-band rasters.
Geopublisher & AtlasStyler are now translated into: German, French, Italian, Russian (thanks to UralGeoInform) and English. AtlasStyler SLD editor is also available in Turkish.
The datapool and mappool can now be filtered by keywords, making the handling of numerous layers easier:
Geopublisher now has a Command Line Interface (CLI) and can export atlases from the command-line:
usage: geopublisher
-a,--atlas <srcDir> Folder to load the atlas from (atlas.gpa). The
path may not contain spaces!
-d,--disk Create DISK version of atlas when exporting.
-e,--export <dstDir> exports an atlas to a given directory, combine
this option with -f / -d and/or -j. The path may
not contain spaces!
-f,--force Overwrite any existing files during export.
-h,--help print this message.
-j,--jws Create JavaWebStart version of atlas when
exporting.
-l,--license Print license information.
-s,--saveandexit Save the atlas after loading and exit. This will
update atlas.xml to the lastest format.
-t,--keeptemp Do not clean temp files, needed if exporting in
parallel
-u,--jwsurl <jnlpUrl> Set the JNLP export URL specifically, overriding
the URL stored in the atlas.xml. Must end with a
/.
-v,--verbose Print verbose information while running.
-z,--zipdisk Zip the DISK folder after export.
AtlasStyler:
The AtlasStyler stand-alone application now has support for WFS! (Mainly tested with Geoserver 2.0.2, and bit with deegree 3).
Redesigned the GUI so that dialogs are more compact:
The AtlasStyler stand-alone application now has a nicer GUI with an Import Wizard for Shapefiles, PostGIS and WFS. You can maintain a list of PostGIS and WFS servers, so that you don't have to reenter information.
When saving .sld files, they are automatically validated against SLD XSD Schema. The user is informed if AS created an unvalidatable SLD file (should not happen).
Under the hood:
Nicer command line output and logging, tested in headless environment.
Added daily testing versions in repository: geopublisher-testing, atlasstyler-testing and geopublishing-doc-testing are now available in the Debian/Ubuntu repository. They are created continuously by the build system.
A "Mail" button has been added to the error dialog. Feel free to press the button and send the exception message with some comments about what you were doing to us.
Automatic cleanup of orphaned directories inside the atlas directory.
All demo atlases are now automatically exported and re-published with the latest stable and the testing versions whenever the SVN changes: atlas.geopublishing.org
If you have any questions/problems/comments please ask them on the mailinglist. Bugs and feature-requests can be reported at the Wald project hosting site. [Less]
