In our first posting (“Processing Landsat 8 data in GRASS GIS 7: Import and visualization“) we imported a Landsat 8 scene (covering Raleigh, NC, USA). In this exercise we use Landsat data converted to reflectance with i.landsat.toar as shown in the first posting.

Here we will try color balancing and pan-sharpening, i.e. applying the higher resolution panchromatic channel to the color channels, using i.landsat.rgb.

1. Landsat 8 – RGB color balancing: natural color composites

After import, the RGB (bands 4,3,2 for Landsat 8) may look initially less exciting than expected.This is easy to fix by a histogram based auto-balancing of the RGB color tables.

To brighten up the RGB composite, we can use the color balancing tool of GRASS GIS 7:

As input, we specify the bands 4, 3, and 2:

Using a “Cropping intensity (upper brightness level)” of 99 (percent), the result look as follows:

For special purposes or under certain atmospheric/ground conditions it may be useful to make use of the functions “Preserve relative colors, adjust brightness only” or “Extend colors to full range of data on each channel” in the “Optional” tab of i.landsat.rgb.

You will need to experiment since the results depend directly on the image data.

2. Landsat 8 pansharpening

Pansharpening is a technique to merge the higher geometrical pixel resolution of the panchromatic band (Band 8) with the lower resolution color bands (Bands 4, 3, 2).

GRASS GIS 7 offers several methods through the command i.pansharpen.

1) Brovey transform:

This module runs in multi-core mode parallelized. The management of the resolution (i.e., apply the higher resolution of the panchromatic band) is performed automatically.

2. IHS transform

Here we select as above the bands in the i.pansharpen interface but use the “ihs” method.

HINT: If the colors should look odd, then apply i.landsat.rgb to the pan-sharpened bands (see above).

Color-adjusted IHS pansharpening (with “Cropping intensity: strength=99″):

Comparison of Landsat 8 RGB composite (39m) and IHS pansharpened RGB composite (15m):

3. PCA transform

Here we select as above the bands in the i.pansharpen interface but use the “pca” method.

Likewise other channels may be merged with i.pansharpen, even when originating from different sensors.

3. Conclusions

Overall, the IHS pansharpening method along with auto-balancing of colors appears to perform very well with Landsat 8.

Thanks to Volker Fröhlich’s efforts, a source code RPM package (SRPM) of QGIS 2.0.1 is now available for Fedora. If you are not yet F20 user (like me), you can just take the F20 package and compile it for F19 (or even F18) since there will be no backport of QGIS 2 to F19 (it comes with QGIS 1.8). But: we do want QGIS 2 on Fedora19!

Solution: compile it yourself.

1. 1. Preparations

The best way is  to use “mock” which is used to recompile SRPMS in a separate local environment (“chroot”) without cluttering the system with extra packages needed for the compilation (run as “root”):

su
yum install mock

2. 2. Get the source code

Next download the SRPM package from the Koji  server:
QGIS:  http://koji.fedoraproject.org/koji/buildinfo?buildID=467757 (–> src – download) or check here for more recent versions.

3. 3. Compile it locally as RPM package

The general compilation command (“mock”) would be:

mock -r my_fedora_version_config --rebuild my_source_rpm.src.rpm

So, check for Fedora version config name which is suitable for your system (“my_fedora_version_config“)

ls /etc/mock/

In my case of a 64bit machine, it is “fedora-19-x86_64″. Hence we can compile QGIS 2.0.1 directly from the SRPM file:

mock -r fedora-19-x86_64 --rebuild qgis-2.0.1-2.fc20.src.rpm

Note: the compilation takes 40min on my tiny core i3 laptop (ASUS X202). Use the time to donate some coins to the QGIS project

4. 4. Install and enjoy

Once the compilation job is done, i.e. the binary RPM files are available for installation. To install the freshly compiled QGIS 2.0.1 RPMs, run:

cd /var/lib/mock/fedora-19-x86_64/result/

# an existing QGIS1.8 installation will be replaced: 
yum localinstall qgis-2.0.1-2.fc19.x86_64.rpm \
qgis-grass-2.0.1-2.fc19.x86_64.rpm qgis-python-2.0.1-2.fc19.x86_64.rpm

# consider to cleanup (or keep it for the next update, it is about 1.5GB):
rm -rf /var/lib/mock/fedora-19-x86_64/
# leave the "root" shell
exit

Now we can happily use QGIS 2.0.1 on Fedora 19!

Note to English speakers

The FOSSGIS-conference is the largest German-language conference for Free and Open Source Software for GIS and Free Geodata hosting about 400 participants.

Today, the Conference Committee announced the “Call for papers” for 2014. Because the conference-language is German, the CfP is either.

The program committee will, however, also consider applications for talks or workshops held in English if they are deeemed to add to the quality of the conference. So if you don’t speak German, but are a FOSS/Open Data celebrity, or have a story that only you can tell, please do submit your talk. We are unlikely to be able to provide interpreters, but we’ll make sure you don’t get lost in Berlin. Please be aware that you can submit paper until November, 15. 2013. You can submit your abstract using our Conference Software.

We are looking forward to see you in Berlin March 19-21, 2014!

The Open Source Geospatial Foundation (OSGeo) is pleased to announce that the U.S. Internal Revenue Service (IRS) has accepted their application (PDF) for non-profit status under section 501(c)(4) of the tax code. Our 501(c)(4) status declares that OSGeo is a Social Welfare Organization. This determination affirms OSGeo’s role in serving the public through their mission, focused around Open Source Geospatial software.

This determination helps ensure that the organization will not have to pay US federal taxes on money accumulated toward the fulfilment of their mission. Unfortunately, unlike a 501(c)(3) (Charitable) status, this does not allow financial contributors to OSGeo to treat the contributions as a charitable contribution which can have a tax benefit for US tax payers. There should still be no problem with commercial organizations treating contributions to OSGeo as a business expense.

OSGeo owes a special debt to past Executive Director Tyler Mitchell, and current Treasurer Daniel Morissette who have carried this process to a successful conclusion after several years of work. Current OSGeo President, Jeff McKenna, says “Both Daniel and Tyler should be thanked by the entire community for their dedication to such a challenging task. Our future foundation events, and OSGeo in general, will benefit from their hard work for years to come.”

About the Open Source Geospatial Foundation

The Open Source Geospatial Foundation, or OSGeo, is a not-for-profit organization founded in 2006 whose mission is to support and promote the collaborative development of open geospatial technologies and data.  The Foundation provides financial, organizational and legal support to the broader open source geospatial community. It also serves as an independent legal entity to which community members can contribute code, funding and other resources, secure in the knowledge that their contributions will be maintained for public benefit.

On 7th Sep 2013 the final results from the 2013 elections for the open seats of the OSGeo Board of Directors have been published. There were four seats open and they have been filled by (in no particular order):

• Jáchym Čepický
• Jorge Sanz

• Gérald Fenoy

Thanks to all candidates for going through the elections and exposing themselves. All six candidates received excellent support with more then 60 votes each. Overall voting participation was 72% (129 out of 180) and there were no tie scores to arbitrate. Thanks to all Charter Members who voted!

The complete resulting OSGeo Board is:

• Anne Ghisla
• Bart van den Eijnden
• Gérald Fenoy
• Cameron Shorter
• Daniel Morissette
• Frank Warmerdam
• Gérald Fenoy
• Jáchym Čepický
• Jeff McKenna
• Jorge Sanz

With the election results published the new board of directors becomes immediately effective.

OSGeo wishes to thank the outgoing directors for their continued support of OSGeo and for helping to run a fantastic organizations with a great membership and lots of energy. We thank all candidates who stood in this election and all OSGeo Charter Members for their contribution and votes.

GRASS GIS 6.4.3 released – Birthday release for 30 years of GRASS GIS
http://grass.osgeo.org

We are pleased to announce the release of a new stable version of GRASS GIS. This release fixes bugs discovered in 6.4.2 version of the program and adds a number of new features. This release includes over
830 updates to the source code since 6.4.2. As a stable release series, the 6.4 line will enjoy long-term support and incremental enhancements while preserving backwards-compatibility with the entire GRASS 6 line.

Key improvements of this release include some new functionality (assistance for topologically unclean vector data), major speedup for some vector modules, fixes in the vector network modules, fixes for the wxPython based portable graphical interface (attribute table management, wxNVIZ, and Cartographic Composer). A number of new modules have been added for processing LANDSAT and MODIS satellite data, and a new vector statistics module is also introduced. Many new symbols and north arrows are available, and the user will find an improved and easier to use wizard for creating custom project locations with precise map projection and datum support. Community-contributed add-on modules are now more easily and robustly installed from an online archive. Other major developments include enhancements to the Python scripting library and numerous software-compatibility fixes and translation updates. Important is the enhanced portability for MS-Windows (native support, fixes in case of missing system DLLs). And we welcome Romanian as our twenty-fourth language!

Disclaimer: strictly offtopic Just a personal health state report, nutshell version…

Maybe some have noted my temporal “disappearance” from email and such in January. The reason was that I spent almost 50 days in hospital since beginning of December. So, what happened?

On 10th December I went to the “Centro Gallucci” of the Padua University Hospital for “routine” examinations in preparation for a future surgery (I know of my heart problems for years; they did not have much effect on my life since I was asymptomatic). But after the initial examinations they scheduled me for an emergency surgery. Err, little shock…

Eventually, I got the open heart surgery on 3rd January (“Bentall-De Bono” method, 7hs of surgery in total, 2hs heart in standstill). During the surgery they realized that the heart state was even worse than known before, with an estimated life expectancy of perhaps months only not having it done immediately (they got me from the cliff). Anyway, the surgery went well, I have now a mechanical valve + ascending aorta (so, you can hear me now :p). BTW: you go in awake, the Padua staff was really nice. And interesting to see how they prepare the surgery, a busy moment (then send make you sleep in no time).

On 10th January I was send to the rehabilitation center (Codivilla-Putti hospital, Cortina d’Ampezzo). However, I got a complication which is not uncommon: inner bleedings with a starting cardiac tamponade as discovered some days later. On 14th January, during heavy snowfall at Cortina, high speed ambulance ride back to Padua, with immediate drainage surgery (lung area and heart, removing more than 2l of liquid). Not really fun… (this little surgery also on a Monday, same time, same room, same staff!). But after some days I got way better. Just 10% of my body weight was meanwhile gone.

On 23rd January I was brought back again to the Cortina rehabilitation center where I spend two nice weeks – no more issues so far

Since 5th February I am back home – and will stay here for a longer while. Various odds and ends need to be resolved first – the recovery is long but steady!
