Serious gaming with Tangible Landscape (all open source and powered by GRASS GIS)
 
Coffee & Viz: Serious games with Tangible Landscape  

An interactive seminar hosted by NCSU's Hunt Library exploring how serious, analytical games can be deployed to simulate real world problems like coastal flooding and the spread of invasive species to help develop innovative solutions. Hands-on games and demos, plus the following lightning talks:

Playing Games with Tangible Landscape, Brendan Harmon, Anna Petrasova, Vaclav Petras, and Helena Mitasova

Participatory Modeling: Engaging Stakeholders with Geospatial Analytics, Jelena Vukomanovic and Ross Meentemeyer

A short exploration how to use the new GRASS GIS g.gui.tplot module to create time series plots
One of the new modules in GRASS GIS 7.03 (RC1) is g.gui.tplot. It is part of the temporal data processing framework (TGRASS) introduced with GRASS GIS 7.0 and lets you plot the values of one or mor...

Just added a little addon which provides a wrapper around d.mon and d.legend to create an image of a smooth legend. Testing and patches welcome

Hi guys,
anyone knows where I can find data with exercises to do with grass. I am preparing a course for students of environmental science. Thank you

winGRASS 64 bit ready for testing

taken from the dev ML (https://lists.osgeo.org/pipermail/grass-dev/2015-December/date.html)

Hi,

2015-12-11 17:20 GMT+01:00 Martin Landa <landa.martin at gmail.com>:
> winGRASS daily builds and addons (http://wingrass.fsv.cvut.cz) will be
> temporary down due to moving building environment from mingw to
> mingw-w64. Please stay tuned.

since today you can start testing 64bit daily builds via standalone
installer (*) [1,2] or through OSGeo4W [3] (`grass-daily`) package. I
also drop dependency on MSYS. So no MSYS installed together with
GRASS.

There are still several open issues:

* GRASS binaries are a bit bigger (39MB vs 49MB compressed). This
difference is caused by bigger exe GRASS files (not sure why, will
investigate later **)
* 64bit Windows installer is 20MB compressed smaller that 32bit (it's
cause by different Python packages in OSGeo4W)
* GRASS Addons are still down (will work on them in the next days)

But it's ready for testing! Enjoy and please report issues;-) Ma

(*) If you have GRASS already installed, please uninstall first from
control panel and then install GRASS 64bit (you need to uninstall
separately otherwise 64bit GRASS will be installed in 'Program Files
(x86)` rather then 'Program Files`).
(**) GRASS packages are now build using mingw32-w64 toolchain using MSYS2 [4]

About this community

Tutorials, Tips, and News Regarding the Open Source GIS Software GRASS. Twitter: @GRASSGIS Youtube: /GRASSGISNews GRASS GIS (Geographic Resources Analysis Support System) is a free, open source geographical information system (GIS) capable of handling raster, topological vector, image processing, and graphic data.
 
 
GRASS GIS, Tangible Landscape and the Center for Geospatial Analytics highlighted in new Data Science Initiative at NC State:

"Imagine being able to hold a geographic information system (GIS) in your hands (...) Researchers at NC State’s Center for Geospatial Analytics have made this novel idea a reality with Tangible Landscape, an open source tangible interface powered by GRASS GIS that physically and interactively manifests geospatial data so that users can naturally feel it, shape it, and immediately see results projected onto the 3-D model."

I am preparing some data sets to be shared online, so I am having a look (again) at the metadata tools in GRASS GIS. One improvement since the last time I have looked at this tool is the option to export metadata as PDF.
The metadata support in GRASS GIS was seriously improved with the introduction of a new metadata management tool back in 2014 during the Google Summer of Code of that year. The addon added tools fo...

This is my first time using GRASS and I'm trying to extract lakes from a DEM. I'm trying to do so using the slope aspect. I only know how to have GRASS give me all slopes, how can I make it filter just slopes that are equal to 0. Could anyone help me? Thank you. I'm attaching a picture that just shows that you can see the lakes are flat so I'm thinking this is a good method, if you know any other methods I would be happy to hear it.
