SAGA 5.0.0 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 5.0.0. This release introduces some major additions to SAGA's API as well as a few minor changes, which might be of relevance for the one or the other SAGA tool developer.

Most efforts have been invested to define a new data object type, which we call 'grid collection'. This is a container for grids, which can be attributed in a very free manner, with the purpose to support the management and analysis of rasters with more than two dimensions like multi- or hyperspectral images, time series, and volumes. At the moment not many tools are dedicated to this new data object type, but grid collections can already be used in tools as input for single grids and grid lists. Display options are similar to those of single grids. The default visualization is colour composite made from three grids of a collection. By default all raster files that provide more than a single band are loaded as grid collection.... read more

SAGA 4.1.0 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 4.1.0. This release brings some bug fixes, probably the most notable is related to vector data export through gdal/ogr, as well as a few additional tools. Very appreciated is the contribution of a cmake based configuring system by Reinhold Gschweicher - this will facilitate the future SAGA development across different platforms and compilers.... read more

SAGA 4.0.1 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 4.0.1. This is a pure bug fix release for the 4.0 series. Affected by problems are some tools with grid system independent input grids (e.g. 'Mosaicking') and gridding tools with distance weighting of observations (Inverse/Angular Distance).

We highly recommend to update to this version, in particular if you already switched to version 4.0.0. We are very sorry for any inconvenience related to these issues.... read more

SAGA 4.0.0 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 4.0.0. Many improvements have been achieved since the last release, to name just a few:

API: mainly of interest for developers include the changes a number of interface simplifications. More of general interest might be the new tool chain options, e.g. direct access and loops (for each) for data object list members.

CMD: The behaviour of the command line interpreter can now be better controlled with configuration files.... read more

SAGA 3.0.0 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 3.0.0. Those of you, who follow SAGA since a longer time, might wonder about the reason to increment the major version number the first time since 2007. Indeed many bigger things changed in SAGA in the past without resulting in a major version leap. But as we already declared in the post for the v2.3.0 release, we started to follow a more progressive and commonly used versioning scheme, thus better reflecting the type of changes between two versions. This time it is an backwards incompatible change in SAGA's C++ API, not very big and not visible for pure front end users, but it might require some adjustments of source codes directly interacting with the API. Sorry for any inconvenience regarding this. As always we did this to make the API more effective and intuitive for you.... read more

SAGA 2.3.0 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.3.0. Starting with this release we will follow a more progressive and commonly used versioning scheme. Simple bug fixes to this release will go into the v2.3.1 branch while major works are done on the master repository for the v2.4.0 release. Together with this change, we switch from svn to git as version control system.... read more

SAGA 2.2.7 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.2.7. A serious bug in the command line interpreter saga_cmd made it necessary to come out with this release that soon (see [bugs:#228] for details). Sorry for this inconvenience.

Thanks a lot for all your valuable contributions.
Enjoy the world of SAGA,
your SAGA Development Team

SAGA 2.2.6 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.2.6. Some problems related to the Linux distributions of SAGA forced us to come out with this release that fast. Therefore most changes are bug fixes, but you will also find some feature enhancements, e.g. now you can select google maps as alternative base map server.

Again, thanks a lot for all your valuable contributions.

SAGA 2.2.4 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.2.4. Besides our usual work on bug fixes and feature requests, we have done some major efforts on certain GUI functions. For instance, you can add a base map from Open Street Map server to your maps in SAGA. The map export to Google Earth ('Save as KMZ') is now simply stored to your temporary directory, if you don't specify an output file. And you can change parameter settings for more than one data set simultaneously, if you selected multiple data sets of the same type. These and more new features are just waiting to be explored by you!... read more

SAGA 2.2.3 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.2.3, which is the third minor release in this row. Not many new features have been added this time, but a number of optimizations (e.g. for viewing tables with millions of records) as well as various bug fixes have been applied, most reported from you (thanks a lot).

And now enjoy the world of SAGA,

SAGA 2.2.2 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.2.2, which is the second minor release in this row. But again it comes with some important bug fixes and a number of exciting new features.

Slight improvements have been added to the ArcSAGA Toolboxes. Please give it a try if you have access to ArcGIS version 10.1 or higher and let us know about your experiences. We spent also some efforts for a better, more intuititive interaction with PostgreSQL/PostGIS databases. You might note that SAGA project files now support database sources as well as various non-native SAGA raster file formats (the latter does not yet work for raster files providing more than one single band). ... read more

SAGA 2.2.1 released

Dear SAGA users and friends,

we like to announce the release of SAGA version 2.2.1, which is a only minor release. Nevertheless it comes with some important bug fixes and a number of exciting new features.

Perhaps most notable are the ArcSAGA Toolboxes, which integrate about 400 SAGA tools into ArcGIS v10.1 and higher. The toolboxes are created automatically and might not always work perfectly. Definitely this is a beta version, therefore we welcome any feedback as well as suggestions for further improvements. To run ArcSAGA tools, you have to navigate to your SAGA installation directory with the ArcCatalog control and open the ArcSAGA Python toolboxes. It should work out of the box without any further installation steps.... read more

SAGA 2.1.3 is released

Dear SAGA friends, users, and all others interested in SAGA,

we like to announce the release of SAGA version 2.1.3.

This release includes new tools, tool enhancements, new functionality regarding the graphical user interface and the introduction of tool chains. Tool chains enable further automation of work flows by combination of other tools. In contrast to other ways of scripting, tool chains can be used like other tools from SAGA GUI and command line interpreter. The coding is XML based. A description about tool chain creation will follow soon. ... read more

SAGA 2.1.2 is released

Dear SAGA friends, users, and all others interested in SAGA,

we like to announce the release of SAGA version 2.1.2.

For this version some efforts have been made to make the graphical user interface more smooth and user friendly. New features include the display of a North arrow, scale bar, and geographic coordinate grids for map views. Enhanced options for interactive vector data editing have been added. Modules are now generally addressed as 'tools' and the modules menu has been renamed to 'Geoprocessing'. Besides this many bug fixes could be applied and you will also find a number of tools, which for sure will be quite interesting for some of you. For example a complete tool set focusing on slope stability has been contributed by Andreas Guenther.... read more

SAGA 2.1.1 is released

Dear SAGA friends, users, and all others interested in SAGA,

we like to announce the release of SAGA version 2.1.1. In this version you will find a number of minor enhancements and additions, which in their sum make it the best SAGA ever. So, don't hesitate to download it right now! This version depends now on the lately released wxWidgets v3.0.

SAGA 2.1.0 is released

Dear SAGA friends, users, supporters, and all others interested in SAGA,

we like to announce the release of SAGA version 2.1.0. This is the first official release since version 2.0.8 in November 2011. Besides the introduction of several new interesting tools the main changes are the migration from wxWidgets v2.8 to v3.0 and the implementation of data and tool management within the SAGA API.

Due to a delay in the wxWidgets project SAGA actually links against its latest development release v2.9.4. But this version already introduces a number of simplifications and enhancements like integration of the wxPropertyGrid project, improved support for Unicode, and a new wxOSX/Cocoa port. Mac users might like to hear that efforts are going on to make SAGA work on MacOS more smoothly. You find a thread regarding the MacOS port in the SAGA User Forum ( http://sourceforge.net/p/saga-gis/discussion/790705/thread/b11de126/ ). Have a look at http://www.wxwidgets.org for background information about the wxWidgets project.... read more

SAGA 2.1 Release Candidate 1

Dear SAGA friends, users and supporters,

the first SAGA 2.1 release candidate has just been prepared for download at http://sourceforge.net/projects/saga-gis/files/. This refers to the Windows binaries only.

SAGA 2.1 Beta

Dear SAGA friends, users and supporters,

version 2.0.8 has been released more than half a year ago and many of you might ask if there is any progress going on with the pending release of the proclaimed version 2.1. Indeed a lot of bug fixes, additions and improvements have been implemented since, but we still don't think that we achieved all of our goals in a satisfying way yet, and with our limited resources it might still take a while to reach that point.... read more
