GRASS 7.2 is out

· ·

….But Randy you’re a month late announcing it. I know. I’m behind.

I’ve become a GRASS fan for the awesome processing power behind this software. For those who have kept up with the blog you’ve seen me do random things with LIDAR. I’ve used it to process Landsat. I’ve used the topology tools to clean up data. For those of you in County Government – did you know you can “network” your road layers and generate drive times for firetrucks? Yes – you can.

From the website:

GRASS GIS 7.2 is the version of active development with a first 7.2.0 stable release in December 2016. In total, it comes with more than 1900 fixes and improvements with respect to the stable releases 7.0.5.

Read here -> https://trac.osgeo.org/grass/wiki/Grass7/NewFeatures72

So if you’re using QGIS you might have updated and then found your QGIS processing toolbox was broken.

  • If you’re on windows – update to 2.18.3 and you’re good with the standalone installer (and I haven’t tested 2.14.10).
  • If you’re on windows with the OSGEO installer – once again update and you’re good.

What if you on Linux like myself – it’s still broken. I spent some time this weekend and as I simultaneously ran on experiment the same thing came over the user list – just link your grass 7.2 binary to grass 7.0 so – if you’re on linux (specifically Ubuntu) and that last part sounded like crazy talk.

  • Open a terminal
  • cd /usr/bin
  • sudo ln -s grass72 grass70

Crank up a GRASS Processing tool in QGIS and you should be back up and running.

 

GIS Day – 2016

· ·

It’s the worst Holiday ever.

So where am I going to be:

and what will I be doing? Well at UTK I’m going to be my usual charming self and discuss all things that are ‘alternative medicine’ in the GIS world. At the other I’m going to discuss LIDAR and GRASS…and annoy whoever I can whenever I can. Track me down – I’ll have info, stickers, and general insanity to spread around.

I’m going to be missing my people at MAGS in Atlanta for their event. So if you’re close to Kennesaw go there and enjoy.

image003

 

Interested in using GRASS GIS as a geospatial processing backend? Or for reproducible research with Python? Or as a surprisingly powerful desktop GIS? Then come to the November GRASS GIS Raleigh meetup which will be specifically focused on getting newcomers started with anything ranging from using GRASS GIS to programing and contributing. The meetup is planned for Saturday, November 5. Meet in 4502 Fishbowl at the Hunt library at NC State Centennial Campus at 2 PM. Map here. Join any time during the afternoon; we will be there at least till 6 PM, but there is an option to stay longer.

Contact Vashek if interested in attending, or if you have any questions:

Classes at UNC in October 2016 on QGIS and GRASS

· ·

From the email bag …and no this isn’t anything I’m doing but I support anyone doing this in the area.

Greetings, all!

Also, at UNC in Chapel Hill there will be a one week short course on Open Source (QGIS and GRASS) GIS that is open to the public. Two, 2-hour classes on QGIS and one 2-hour class on GRASS, running Oct. 24, 26, and 28:

http://www.irss.unc.edu/odum/contentSubpage.jsp?nodeid=21

Introduction to the QGIS Open Source Software: Part 1

Scott Madry
This will be the first of two, 2-hour hands-on workshops using the QGIS open source GIS package. This first workshop will begin with an overall introduction to the “OSGEO Stack” of open source GIS tools, including QGIS, GRASS, R and other tools. Then we will explore the QGIS software, which can run on Windows, Mac or Linux environments, runs in over 40 languages, and includes vector, raster, georegistration, and other capabilities, all using ESRI shapefiles as the basic vector data structure and Geotiffs as the basic raster data structure. The first workshop will be a general introduction to the QGIS user interface and will explore the various elementary functions, loading vector and raster data, etc. Additional tutorials and data will be made available to the participants so you can continue to work on your own. Feel free to bring your own laptop so you can download the software, tutorials, and data, or use a computer in the lab.

There is no fee for this course.

No registration required. UNC students, faculty, and staff will need to show their UNC OneCard.

Date: October 24, 2016

TImes: 10:00am – 12:00pm

Introduction to the QGIS Open Source Software: Part 2

Scott Madry
The second class will continue the introduction to the QGIS software. We will explore various plugins, including live linking OpenStreetMaps and Bing maps and images, creating cartographic maps using the composer cartographic interface, working with vector attribute tables, and downloading and working with raster satellite imagery. Web resources will be explored. Additional tutorials and data will be made available to the participants so you can continue to work on your own. Feel free to bring your own laptop so you can download the software, tutorials, and data, or use a computer in the lab.A

Introduction to the GRASS Open Source GIS and image processing software

Scott Madry
This third 2-hour workshop will cover the GRASS GIS package, which is included in the QGIS download and can be used either as a set of integrated tools in the QGIS environment, or run as the stand-alone GRASS package. GRASS is the original open source GIS package, and is a very powerful and integrated GIS, image processing, spatial analysis, visualization and modeling environment. The first hour of the workshop will use GRASS within the QGIS environment, where data can be used as GRASS files in the same environment as QGIS shapefiles, and can be converted easily between the two. The current QGIS software can now call all of the GRASS functions (over 400) remotely and does raster and vector data format conversion on the fly. In the second hour we will use GRASS in its stand-alone configuration. Additional tutorials and data will be made available to the participants so you can continue to work on your own. Feel free to bring your own laptop so you can download the software, tutorials, and data, or use a computer in the lab.

There is no fee for this course.

No registration required. UNC students, faculty, and staff will need to show their UNC OneCard.

For those from Raleigh area:

Intro to GRASS GIS

Geospatial Studio this Thursday at NC State University

September 8, 3:30 pm – 4:30 pm

Take your first steps in GRASS GIS by attending the Geospatial Studio and learning how to use this free (as in freedom) software at this free (as in free beer) event. After the introduction, there will be time to try your own data in GRASS GIS. Attendees are encouraged to bring their own laptops. Please arrive a few minutes early if GRASS GIS is not already installed on your computer.
