Today marks 35 years of GRASS GIS development – with 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.

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. 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 ).

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. 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, which will bring many new features, enhancements, and cleanups.

GRASS GIS is a founding member of the Open Source Geospatial Foundation (OSGeo). The GRASS Development Team, October 2016 The post appeared first on. Towards the new stable release series As of 24 May 2016, a new stable release branch was created for the upcoming GRASS GIS 7.2 release.

This new branch includes all the many improvements which have been implemented in the former development version 7.1.svn. What is a branch? In simple words, it is a kind of directory in the software development server ( in our case) in which no more development but only bugfixing happens. From a release branch, new stable releases are created and published.

Press release From March 2016 onwards, Dr. Markus Neteler, a prominent head of the Open Source GIS scene, will join the management board of mundialis GmbH & Co. KG in Bonn, Germany. Founded in 2015, mundialis combines remote sensing and satellite data analysis in the field of Big Data with Open Source WebGIS solutions.

Since 2008, Dr. Neteler was the head of the GIS and remote sensing unit at the Edmund Mach Foundation in Trento (Italy) and worked in this capacity on numerous projects related to biodiversity, environmental and agricultural research. He is also a founding member of the Open Source Geospatial Foundation (OSGeo), a nonprofit organization with headquarters in Delaware (USA), that promotes the development and use of free and open source geographic information systems (GIS). Since 1998 he coordinated the development of the well known GRASS GIS software project, a powerful Open Source GIS that supports processing of time series of several thousand raster, 3D raster or vector maps in a short time. Markus will keep his role as “Mr. GRASS” at, especially because the company also sees itself as a research and development enterprise that puts its focus on the open source interfaces between geoinformation and remote sensing.

Although a new company, mundialis offers more than 50 years of experience in GIS, due to the background of its management. Besides Neteler, there are Till Adams and Hinrich Paulsen, both at the same time the founders and CEOs of terrestris in Bonn, a company that develops Open Source GIS solutions since 2002. These many years of experience in the construction of WebGIS and Geoportal architectures using free software as well as in the application of common OGC standards – are now combined with mundialis’ expertise in the processing of big data with spatial reference and remote sensing data.

Routing with GRASS r.walk (Green areas are walk-friendly, yellow/orange areas are harder to cross, and red buildings are basically impassable.) The route crosses the square – like any sane pedestrian would. The key steps are:. Assigning pedestrian costs to different polygon classes. Rasterizing the polygons.

Computing a cost raster for moving using r.walk. Computing the route using r.drain I’ve been using GRASS 7 for this example. GRASS 7 is not yet compatible with QGIS but it would certainly be great to have access to this functionality from within QGIS. Sometimes, we developers get reports via that this & that would not work on whatever operating system. Should we be so kind and install the operating system in question in order to reproduce the problem? Too much work but nowadays it has become much easier to perform such tests without having the need to install a full virtual machine – thanks to.

Disclaimer: I don’t know much about docker yet, so take the code below with a grain of salt! In my case I usually work on Fedora or Scientific Linux based systems. In order to quickly (i.e. Roughly 10 min of automated installation on my slow laptop) try out issues of GRASS GIS 7 on e.g., Ubuntu, I can run all my tests in docker installed on my Fedora box: # we need to run stuff as root user su # Fedora 21: install docker yum -y docker-io # Fedora 22: install docker dnf -y install docker # enable service systemctl start docker systemctl enable docker Now we have a running docker environment.

Since we want to exchange data (e.g. GIS data) with the docker container later, we prepare a shared directory beforehand: # we'll later map /home/neteler/data/dockertmp to /tmp within the docker container mkdir /home/neteler/data/dockertmp Now we can start to install a Ubuntu docker image (may be “any” image, here we use “Ubuntu trusty” in our example).

GRASS GIS 7 GUI in docker container You may now perform all tests, bugfixes, whatever you like and leave the GRASS GIS session as usual. To get out of the docker session::/# exit # leave the extra bash shell:/# exit # leave docker session # disable docker connections to the X server neteler# xhost -local:docker To restart this session later again, you will call it with the name which we have earlier assigned: neteler# docker ps -a #. You should see 'grass70trusty' in the output in the right column # we are lazy and automate the start a bit neteler# GRASSDOCKERID=`docker ps -a grep grass70trusty cut -d' ' -f1` neteler# echo $GRASSDOCKERID neteler# xhost +local:docker neteler# docker start -a -i $GRASSDOCKERID ###.

How do you objectively define and compute which parts of a network are in the center? One approach is to use the concept of centrality. Centrality refers to indicators which identify the most important vertices within a graph.

Re: Grass-dev New Attempt To Update Grass For Mac Free

Applications include identifying the most influential person(s) in a social network, key infrastructure nodes in the Internet or urban networks, and super spreaders of disease. (Source: ) Researching this topic, it turns out that some centrality measures have already been implemented in GRASS GIS. As a test, I’ve loaded the OSM street network of Vienna and run v.net.centrality -a 000 output=centrality degree=degree closeness=closeness betweenness=betweenness eigenvector=eigenvector The computations take a while. In my opinion, the most interesting centrality measures for this street network are closeness and betweenness: Closeness “measures to which extent a node i is near to all the other nodes along the shortest paths”. Closeness values are lowest in the center of the network and higher in the outskirts. Betweenness “is based on the idea that a node is central if it lies between many other nodes, in the sense that it is traversed by many of the shortest paths connecting couples of nodes.” Betweenness values are highest on bridges and other important arterials while they are lowest for dead-end streets.

(Definitions as described in more detail in ). 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.

GRASS GIS 7 just got better: When reprojecting vector data, now automated vertex densification is applied. This reduces the reprojection error for long lines (or polygon boundaries).

The needed improvement has been kindly added in. Comparison of the reprojection of a 10 degree large LatLong box to the metric EU LAEA (EPSG 3035): before in red and new in green. The grid is based on WGS84 at 5 degree spacing. The result shows how nicely the projection is now performed in GRASS GIS 7: the red line output is old, the green color line is the new output (its area filling is not shown). Consider to benchmark this with other GIS the reprojected map should not become a simple trapezoid.
