Hi Luis,
You can only use ASCII characters a-z A-Z 0-9.
If you have a folder with other characters (as in your name) or space, the
program get an error.

Tnx to Nicolas for the input concerning how to work-around the problem
with the Google images.
And I will try to use Landsat images first, some years ago I did, now it

Hello People.
I am writing to tell you that want to perform supervised and unsupervised
classification of images SPOT 5. The aim is to to see the different land
uses having the study area. How I can make these classifications with QGIS?
Once you make the classification (with QGIS), I want to apply
The ogr2osm python script works great for converting shapefiles to .osm
files. I use the one found at https://github.com/pnorman/ogr2osm.
ogr2osm allows you to create a translation script to convert shapefile
features to osm tags. The github repository includes examples of the
translation tables.

No, it is not possible, because the OSM driver is read-only.

Hi,
I am not sure you can use max value in QGIS raster calculator. (Please correct
me if I am wrong).
I think you can do it with gdal calc.py. and most likely in Grass or Saga
using the processing plugin.

Hi,
I would have a column ID each polygon or multipolygone with a unique name. I
would then densify the geometry to create new vertex along the line then
extract these vertex to a point layer. I would then use the point value plugin
to extract the value of the DEM for each point and then use

Hi,
I would use the Raster calculator (Processing > GDAL/OGR) for this.
This uses gdal_calc.py. Google for more info about usage.
The maximum of two layer would be done like this:
maximum(A,B)
this should also work for multi-bands but I have never tried this..
Compared rasters need to have the s

That change won't be backported to 2
dear community
I have a stack (bsq) of 5 images.
I would like to make an aggregate map of the maximum of each pixel of the
bands.
I Googled and I found contrasting opinions on how to do it.
Can you help me?
Thank you

Hello,
Someone has any ideas?
It seems that the bug has been already notified : hub.qgis.org/issues/8995
The ticket seems to be closed 2 months ago. But, on my side (qgis 2.8.1),
the bug is not fixed...

Hi,
Best bet is, that you have some special characters in your path or file
name, which are not strictly ascii. So nothing with R itself.
But to be honest, I never got R running successfuly on my machine as well
for other reasons ;)

Hello everyone,
I have problems to work with the R algortihms in QGIS. I'm using Windows
