v.in.gshhs

Hi,

Trying to import GSHHG V2.2.2 ( see 
http://www.soest.hawaii.edu/pwessel/gshhg/ ) through 'v.in.gshhs', I ran 
into this:

GRASS 6.4.2 (wgs84):~/tmp/gshhs_bin > v.in.gshhs gshhs_c.b out=gshhs_c
Using lat/lon bounds N=90.000000 S=-90.000000 E=180.000000 W=-180.000000
ERREUR :Trying to import version 3, only GSHHS versions 4 to 8 (2.0) are 
supported.

which looks strange to me. I am currently doing some 'v.in.ogr' on the 
Shapefile version of GSHHS, but the process appears to be quite long for 
the "high" and "full" resolution (assuming one wants to import the whole 
dataset without using '-c'), so I was hoping 'v.in.gshhs' would be 
quicker... please let me know if this is a known issue, or something I 
did wrong, etc.

Nicolas

Grass repository for Ubuntu 12.04 LTS and duplicate.sources.list error

Dear all,

 From Ubuntu Ubuntu 12.04 LTS 64bits I am trying to install grass-dev 
using synaptic. I get this error:

W: Duplicate sources.list entry 
http://ppa.launchpad.net/gcpp-kalxas/ppa-tzotsos/ubuntu/ precise/main 
amd64 Packages 
(/var/lib/apt/lists/ppa.launchpad.net_gcpp-kalxas_ppa-tzotsos_ubuntu_dists_precise_main_binary-amd64_Packages)
W: Duplicate sources.list entry 
http://ppa.launchpad.net/gcpp-kalxas/ppa-tzotsos/ubuntu/ precise/main 
i386 Packages 
(/var/lib/apt/lists/ppa.launchpad.net_gcpp-kalxas_ppa-tzotsos_ubuntu_dists_precise_main_binary-i386_Packages)

I understand that there is a duplicate in my sources.list, but cannot 
figure out which one. Here are the repositories that I have added:

# to get GRASS updated
deb http://ppa.launchpad.net/gcpp-kalxas/ppa-tzotsos/ubuntu precise main
deb-src http://ppa.launchpad.net/gcpp-kalxas/ppa-tzotsos/ubuntu precise 
main

# to get QGIS
deb http://qgis.org/debian precise main
deb-src http://qgis.org/debian precise main

# to get R
deb http://cran.univ-lyon1.fr/bin/linux/ubuntu precise/

Any hint appreciated.

Import conditioned DEM from HydroSheds

Hi,

I'd like to use the conditioned DEM from HydroSheds (15sec resolution)
in GRASS to extract rivers etc. using r.watershed. On the HydroSheds-
Website (http://hydrosheds.cr.usgs.gov/dataavail.php) there are two possible
file formats: bil and esri grid. 

The esri grid folder for Europe (eu_dem_15s) contains several files all with .adf ending and metadata (htm, xml).
The bil folder contains the eu_dem_15s.bil and a *.hdr and *.prj and some more.

Which format is prefered for importing into GRASS? I guess its the .bil as there is only
one bil-file with the different addtional info (header, projection etc.). Which format type
is the .bil in r.in.gdal?

/Johannes

I've checked Nabble forum comments re installing extensions but cannot find
a solution.

What would be the best method to install? Is there a manual way of
installing an extension?

Cheers,

Airborne LiDAR data strip adjustment

     Hello to all using GRASS,

     I received ALS data, which is with overlapping strips in both directions, east-west and north-south. Is it available some algorithm to do a strip adjustment in GRASS GIS or any other software, so I can build cleared DEM (without overlapping data)?


     Greetings,

     Adrian Kirilov

Merge polygone with same attribut of a shapefile

Dear all,

I'm trying to merge all polygones with the same attribut of a shapefile. I saw it is possible to merge
adjacent polygone with r.dissolve but I didn't found how to do this with polygones that are not adjacent.
Is there a way to do this?

My goal is to minimise the number of feature into my table in order to have only one feature by category, but
containing several polygones.

Regards

Lucien

EPSG code spearfish dataset

Hi,

is there any EPSG code defined for the projection of the spearfish sample dataset?
Or a EPSG code that is close to the projecton? I am just asking as there is a code
provided for the NC-dataset but not for the Spearfish.

cheers,

/johannes

Failed export of vector, missing attribute column

Hi,

I wanted to export a point vector to a .shp file. This works except for
a column that does not get exported. I have tried it in grass70 and grass65 (in Ubuntu)
but both without success. The attribute column that is not exported was created
in the attribute table view and populated with a sqlite-command. The column
is of type DOUBLE and stores the value 0.5 for all points.

Here the error (in grass65, but the same in grass70) :
v.out.ogr -e --overwrite input=barriers <at> PERMANENT type=point dsn=/path/to/output
Warning 1: Field Riv of width 1000 truncated to 255.
Warning 1: Field Site of width 1000 truncated to 255.
Warning 1: Field type of width 1000 truncated to 255.
ERROR 6: Failed to add field named 'passability'
Exporting 20 geometries...

What is the reason for that and how can it be solved?

Best regards,
Johannes

Sky-view Factor and GeoTiff Histogram equalization (stretch)

     Hello to the GRASS users,

     Does anybody know how to equalize, or stretch, the histogram of a raster? The last represents Sky-view Factor based on a DEM model. It is well-known visualization technique when looking for archaeological structures.

     I have to do minimum-maximum stretch of the histogram with saturation of minimum. How to do this in GRASS? Any help will be highly appreciated! Thank you!


     Greetings,

     Adrian Kirilov

Re: bug with r.reclass

Dear All:
 
I am trying to use the grass i.atcor for atmospheric correcction. Would you give me a clue what the ''text file'' to be used asone of the input parameters and if possible the sample/format of the file. The dialogue window for input image does not seem to allow uploading the raster file. Any assistance is very much appreciated.
 
Best regards,

Subject: [GRASS-user] bug with r.reclass
To: "grass-user <at> lists.osgeo.org" <grass-user <at> lists.osgeo.org>



Dear all,

I'm facing a problem with r.reclass on GRASS 6.4.2 on Linux mint.

r.reclass seems to have a small bug.
I worked with output name "test" , but then, It didn't work any more with others output names...
This the command I did:
r.reclass --overwrite input=input <at> mapset output=test rules=path
With the rules:
3 thru 7 = 1
* = NUll

I received the following error when I tried to display the raster or to see the metadata (In french, sorry!):
It says that it is not possible to find the history of the file and to read the boundary file (or limit file)
(Wed May 15 15:28:43 2013)

Do someone has an idea what the problem is ?
