GRASS GIS 8.0.0 released! Finally…

1. Overview of changes

After more than 3 year of development the first stable release GRASS GIS 8.0.0 is available. Efforts have concentrated on making the user experience even better, providing many new useful additional functionalities to modules and further improving the graphical user interface.

Breaking news: new graphical user interface with entirely rewritten startup sequence!

This re-establishes user experience compatibility with QGIS and other connected software packages.

The GRASS GIS 8.0.0 release provides more than 1,400 fixes and improvements with respect to the release 7.8.6.

With the introduction of the semantic label raster metadata class, the temporal database was modified to version 3. Hence, to be able to read and process GRASS 7.x space-time datasets, users will be prompted to run t.upgrade. If users want to read newly created space-time datasets back in GRASS 7.x, they can run t.downgrade.

Launching the software

The user experience of the graphical user interface has been completely rewritten: no more clumsy selection screens – just enter the menu system directly! And on command line, GRASS GIS now starts versionless, i.e. as grass. Enjoy!

Happy birthday OSGeo!

On February 4, 2006 OSGeo held its first meeting in Chicago, with 25 participants representing 18 groups and over 20 different Open Source GIS projects, and 39 others participating via Internet Relay Chat. During the meeting, participants made important decisions in the formation and organization of the foundation, including the name, structure and purpose. The consensus reached in Chicago opened the way for the establishment of a productive and representative foundation.

Today we are happy to announce that the we have meanwhile over 32,800 unique subscribers in the huge list of over 290 OSGeo mailing lists!

And: check out the web site of the OSGeo foundation.

Celebrating 35 years of GRASS GIS!

Today marks 35 years of GRASS GIS development – with frequent releases the project keeps pushing the limits in terms of geospatial data processing quality and performance.

GRASS (Geographic Resources Analysis Support System) is a free and open source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and map production, spatial modeling, and 3D visualization. Since the major GRASS GIS 7 version, it also comes with a feature rich engine for space-time cubes useful for time series processing of Landsat and Copernicus Sentinel satellite data and more. GRASS GIS can be either used as a desktop application or as a backend for other software packages such as QGIS and R. Furthermore, it is frequently used on HPC and cloud infrastructures for massive parallelized data processing.

Brief history
In 1982, under the direction of Bill Goran at the U.S. Army Corps of Engineers Construction Engineering Research Laboratory (CERL), two GIS development efforts were undertaken. First, Lloyd Van Warren, a University of Illinois engineering student, began development on a new computer program that allowed analysis of mapped data.  Second, Jim Westervelt (CERL) developed a GIS package called “LAGRID – the Landscape Architecture Gridcell analysis system” as his master’s thesis. Thirty five years ago, on 29 July 1983, the user manual for this new system titled “GIS Version 1 Reference Manual” was first published by J. Westervelt and M. O’Shea. With the technical guidance of Michael Shapiro (CERL), the software continued its development at the U.S. Army Corps of Engineers Construction Engineering Research Laboratory (USA/CERL) in Champaign, Illinois; and after further expansion version 1.0 was released in 1985 under the name Geographic Resources Analysis Support System (GRASS). The GRASS GIS community was established the same year with the first annual user meeting and the launch of GRASSnet, one of the internet’s early mailing lists. The user community expanded to a larger audience in 1991 with the “Grasshopper” mailing list and the introduction of the World Wide Web. The users’ and programmers’ mailing lists archives for these early years are still available online.
In the mid 1990s the development transferred from USA/CERL to The Open GRASS Consortium (a group who would later generalize to become today’s Open Geospatial Consortium — the OGC). The project coordination eventually shifted to the international development team made up of governmental and academic researchers and university scientists. Reflecting this shift to a project run by the users, for the users, in 1999 GRASS GIS was released under the terms of the GNU General Public License (GPL). A detailed history of GRASS GIS can be found at https://grass.osgeo.org/history/.

Where to next?
The development on GRASS GIS continues with more energy and interest than ever. Parallel to the long-term maintenance of the GRASS 7.4 stable series, effort is well underway on the new upcoming cutting-edge 7.6 release, which will bring many new features, enhancements, and cleanups. As in the past, the GRASS GIS community is open to any contribution, be it in the form of programming, documentation, testing, and financial sponsorship. Please contact us!

PDAL 1.6.0 packaged for Fedora including vertical datums and grids

Cologne city shown as colorized 3D point cloud (data source: openNRW Germany)In order to simplify the installation of the latest PDAL release (Point Data Abstraction Library, http://www.pdal.io/, version 1.6.0) on Fedora, I have created an updated set of RPM packages now including vertical datums and grids (.gtx files from here).

The installation is as simple as this (the repository is located at Fedora’s COPR):

# enable extra repos to satisfy dependencies
sudo dnf copr enable neteler/pdal-hexer
sudo dnf copr enable neteler/points2grid

# install dependencies
sudo dnf install hexer
sudo dnf install points2grid

# enable and install PDAL
sudo dnf copr enable neteler/pdal
sudo dnf install PDAL PDAL-devel PDAL-vdatums

# run PDAL:
pdal-config --version
pdal --help

Enjoy!

GRASS GIS 7.2.1 released

We are pleased to announce the update release GRASS GIS 7.2.1

GRASS GIS 7.2.1 in actionWhat’s new in a nutshell

After four months of development the new update release GRASS GIS 7.2.1 is available. It provides more than 150 stability fixes and manual improvements compared to the first stable release version 7.2.0. An overview of new features in this release series is available at New Features in GRASS GIS 7.2.

About GRASS GIS 7: Its graphical user interface supports the user to make complex GIS operations as simple as possible. The updated Python interface to the C library permits users to create new GRASS GIS-Python modules in a simple way while yet obtaining powerful and fast modules. Furthermore, the libraries were again significantly improved for speed and efficiency, along with support for huge files. A lot of effort has been invested to standardize parameter and flag names. Finally, GRASS GIS 7 comes with a series of new modules to analyse raster and vector data, along with a full temporal framework. For a detailed overview, see the list of new features. As a stable release series, 7.2.x enjoys long-term support.

New stable release of GRASS GIS 7.0.0!

The GRASS GIS Development team has announced the release of the new major version GRASS GIS 7.0.0. This version provides many new functionalities including spatio-temporal database support, image segmentation, estimation of evapotranspiration and emissivity from satellite imagery, automatic line vertex densification during reprojection, more LIDAR support and a strongly improved graphical user interface experience. GRASS GIS 7.0.0 also offers significantly improved performance for many raster and vector modules: “Many processes that would take hours now take less than a minute, even on my small laptop!” explains Markus Neteler, the coordinator of the development team composed of academics and GIS professionals from around the world. The software is available for Linux, MS-Windows, Mac OSX and other operating systems.
