[GRASS-user] loading kc50 palsar datasets in GRASS
This site provides PALSAR 50m Orthorectified Mosaic Product. http://www.eorc.jaxa.jp/ALOS/en/kc_mosaic/kc_mosaic.htm I tried running gdalinfo to the directory, img and header files, but gdal doesn't recognize the format. There is pdf (below the webpage) but I can't find any reference to the file formats that is supported by GDAL and GRASS. Has anyone used this dataset in GRASS? PS. This is the only dataset without clouds I can find for my study area (for obvious reasons :)). -- cheers, maning -- "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Hy Daniel. I do not think that r.cross can solve the problem. With r.cross I could get a concatenation of label: For example, with values A = 12 B = 3323 C = 1 the result with the label "category 12, category 3323, category 1" However, if you know a chance I can prove otherwise. As a result, the value of cell in the raster output should be 12332301 Ciao Gabriele -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Values-from-multiple-raster-to-link-together-tp5741032p5766350.html Sent from the Grass - Users mailing list archive at Nabble.com. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Ok, I misunderstood your problem. You want the concatenated values, not just the map of the different crossings.

'target' because the source map can be georeferenced as is probably the case in your example and you want to improve georeferencing of the source map, i.e. you want to georectify some images.

Yes, one of the images you want to georectify. In the new Georectifier, the selection is restricted to the images in the chosen group to avoid confusion, and the fields are labelled source and target where appropriate.

yes, maybe with grep and r.cross ... but then you think you can "convert" the result of r.cross as cell value?

Re: [GRASS-user] how to install libLAS on MAC for use in GRASS and maybe R?
Hi William, thanks for your advice and great website! I will try to compile liblas via cmake for mac osx. I have downloaded and installed cmake-2.8.3 and now I downloaded the boost package (boostI-jam-3.1.18-1-macosxx86_64.tgz). Following the http://www.boost.org/doc/libs/1_45_0/more/getting_started/unix-variants.html I just need to unzip on the right location. Which location would you recommend? Will boost install cause potential problems? Should I do something different than described here http://liblas.org/compilation.html#optional-libraries to configure the optional libraries (gdal and geotiff installed before the grass install via your website)? All tips are welcome. Having the liblas library options for grass and R would be great as I am working with terrestrial lidar data (las 1.1 and 1.2) and these files are quite large.

[GRASS-user] Re: Values from multiple raster -
I have a new problem, this time I would like to concatenate two maps A and B.
A is with 8 digits, B is with 4 digits. So I do as usual:
r.mapcalc "output" = "((" A "* 1) (" B "))"
But I get strange values with negative values. I did several tests but
without resolve. Perhaps r.mapcalc may have problems with numbers greater
than 10 digits
Thanks

Re: [GRASS-user] Re: Values from multiple raster -
It's not r.mapcalc fault. I imagine it's probably a limitation due to
the number of bits in your image. For instance, 8 bit images can have
up to 256 values. 16 bit images can have 65,535. So, if you have too
many values, you will have problems. Not sure how to avoid this in
your case but, maybe you will need to work with categories after all.
Are you planing on doing any math operations in the concatenated
values or is it more for displaying pourposes?
Cheers

CELL maps contain signed, 32-bit values using sign-bit representation,
so the range is -2147483647 to 2147483647 inclusive (i.e. -(2^31-1) to
2^31-1). So you aren't going to be able to store 12-digit numbers in a
CELL map.
DCELL maps use the C "double" type, which on most systems is IEEE-754
double precision, which has a 53-bit mantissa, plus a separate sign
bit. That can exactly represent any integer between -9007199254740992
and 9007199254740992 inclusive (i.e. almost 16 decimal digits).
However, depending upon what you want to do with the result, this may
not be an option, as not all modules can work with floating-point
data.

Hy Glynn.
Thanks for the interesting explanation.
I did then so:
r.mapcalc "A_new = (double(A)) and r.mapcalc "B_new = (double(B))
and then
r.mapcalc "output" = "(("A_new" * 1)+("B_new" ))"
I need to check the result, but it seems that the result is right.
Thank you very much

[GRASS-user] GRASS user map - added twice
Hi everyone! Today I tried adding myself to the Worldwide GRASS GIS usermap and succeeded in doing so. However due to internet connection issues I had to refresh the page. It resulted in my name appearing and counting twice(earlier there were 1421 users, now it is 1423). I find no ways to delete the extra point. Therefore I would like to know how to go about regarding this issue. I am even ready to contact the administrator for the map site if someone could provide me the email id.

The same result can be achieved with one command:
r.mapcalc "output = A * 1.0 + B"
The multiply will cause A to be converted to double to match the other
argument (floating-point constants are double unless an explicit "f"
suffix is given), the multiply will yield a double result, and the
addition will convert B to double to match this.
