[GRASS-user] import .flt grid into grass

[Raphael.Viscarra-Rossel]

Hello,


A while back I posted a question about exporting .flt grids from grass. I
am still struggling with this, but now I have another question regarding
these files.  

I have 100¹s of these files (from a time series of data) that a colleague
produced for me in arcmap.  I have tried to import them into GRASS (as I
do not use or like arc ;-) but have not been able to do.

Any suggestions on how this might be possible? Or is it not?

I searched for answers on the web and list but I only came to some old
posts where the links to the conversations were no longer available.

Any ideas will be very welcome. Thank you.

Raphael.

I ended up reloading the rasters. It took some time and processing but well, 
it's done. Thanks for the suggestions.

[Raphael.Viscarra-Rossel]

Hi Markus,
Yes…not sure where the double @ comes from – it just displays this in the error 
message…
I looked at the  files in the cellhd folder (which I assume are the header 
files) and they seem fine:
proj:   3
zone:   0
north:  9:59:50.99856S
south:  43:38:32.993713S
east:   153:38:23.977878E
west:   112:54:41.983744E
cols:   48874
rows:   40374
e-w resol:  0:00:03
n-s resol:  0:00:03
format: -1
compressed: 1

This is strange…any other hints will be appreciated. Thank you for your help. 
Raphael.

This double @ is a bit fishy.
Can you check where it comes from?

The header file is a text file. Is it there?

Hello Moritz,

Thank you for the suggestions. r.info returns the following
WARNING: can't read range file for [toc10 in toc]
ERROR: Unable to read range file


The frange file I found seems to be there but it is not readable.

I am beginning to thing that whatever I deleted was not recovered and that
I will need to read the data back into grassŠ
What a pain!

Thank you all for your suggestions.

Hello,

Recently, some grass files that were on my computer were accidentally
deleted - I recovered them from backup but it seems that maybe not all.
When I open grass and load up a raster with d.rast the map does not appear
and I get the following error message:

WARNING: Raster map : format field in header file invalid

ERROR: Unable to open raster map 



Does anyone know what might be missing? And if there is a fix to this?
It seems to have happened to all of the rasters that I have in that
project!

Thank you - Raphael.

[GRASS-user] grass7 will not display raster

[Raphael.Viscarra-Rossel]

Hello Hamish,

I installed GRASS 7 (following Markus'  hint to install GEOS frwk also).
GRASS7 and the GUI start and all seems fine until I try to display a raster map 
– it does not display.

I thought that it might be because the mapset was created in an older version 
of GRASS (6.4.2) but I started a new project and imported a raster into a new 
map set in G7 – still not displaying.  I can draw a histogram of the raster 
data but I cannot view the map.

When I start GRASS7, I get the message below, but I do not know what it means.

I use a Mac.  Will appreciate any help with this.  Thank you.

 I wonder if anyone knows how to create a common colour scale for

 More specifically, I have six raster maps of rainfall for different
 time periods (each has a different range of values) and I would like
 to display them all with the same colour scale. The colour scale
 needs to be constructed using the min and max values of the set of
 six maps (and not just individual maps.
 
 
 For only 6 maps I wouldn't bother with scripting a mix,max variable,
 just run r.info in a loop and copy out the min,max by hand.
 
 for MAP in `g.mlist rast pattern=rain*` ; do
   r.info -r $MAP
 done
 
 then make a dummy map with r.mapcalc with overall min and max range.
 
 min=1.2345
 max=9.8765
 r.mapcalc color_map = if(row  10, $min, $max)
 
 and then apply it with:
 
 for MAP in `g.mlist rast pattern=rain*` ; do
   r.colors $MAP rast=color_map
 done
 
 Or run r.colors with the rules= option to set up some color rules
 by hand, then apply to all in a loop.
 
 
 But what I usually do these days in GRASS 6 is to use the r.stack
 addon module to temporarily consider all the maps together, which
 allows for the nice 'r.colors -e' equalized histogram color scaling.
 You can copy the color map to a small dummy raster with the r.colors
 rast= option then delete the stacked raster map if you want to save
 space, then apply it to all maps as in the Bourne shell loop above.

Hi Raphael,

I do recommend upgrading and going the way Anna mentioned, especially if you 
are dealing with a large number of maps. But if that is not an option here are 
the steps I'd take:

1) run r.infohttp://r.info -r on each map to get the min/max range
2) user r.colors with one of the maps and the rule option to set you color 
table to that map. Your rules might look something like this
min_value red
(max - min)/2 yellow
max_value blue
end
-- by substituting the min / max in the above you get a colortable going from 
red to blue with yellow in the middle
3) copy the color table you just set to the other maps using r.color rast 
option. Take a look at r.color man page for more info

Daniel, I wonder how I might display the ‘common’ colour legend when

When the maps are visualised, the colour legend changes to the min max of the 
current map displayed.

Anna, I use GRASS 6.4.2 – so I guess I should upgrade…

Thank you again.

Hi,

in case you use GRASS 7, r.colors accepts multiple maps or a file with the map 
names. So this should do it:
r.colors map=precip1,precip2,precip3 color=precipitation

Also, have a look at temporal modules (GRASS 7 only). You can register the 
series of maps as a dataset (t.create, t.register) and then you can easily get 
the min, max values for the entire series and there is also t.rast.colors.

Anna

This is what I did some time ago when I had the same problem

2) Use r.colors with the rules option to compose a colortable that cover my

3) Apply the same colortable to all maps
4) plot and be happy

Hope it helps

[GRASS-user] problems with installation of grass 7

[Raphael.Viscarra-Rossel]

Hello,

I downloaded grass 7.0(beta) from 
http://grass.osgeo.org/download/software/mac-osx/ and all the framework 
packages too.

Installed them but I cannot get the grass7 guy to run. Errors are below.

[GRASS-user] How to extract multiple raster values to points

[Raphael.Viscarra-Rossel]

Hello,
I wonder if there is a way to extract/sample (eg using nearest neighbour) the 
values from multiple rasters that correspond to a set of to vector points into 
a table.
I could find a way to do this for one raster, but not for multiple rasters. Has 
anyone done this in GRASS? 
Thank you,
Raphael.

 @devs: I wonder if the hint in

 would help which suggests the usage of wx.CallAfter
 (http://wiki.wxpython.org/CallAfter)

Hi,

I added CallAfter as suggested (r51089), let's see if it helps.

 Did you install PIL? ?It's a separate package to install (I have one on my 
 Python page). ?I didn't realize PIL was used in the GUI now. ?I'll add it to 
 the list of requirements.

PIL is required because wxPython is not able to display PostScript
file which is the product of underlying module ps.map.

Dear list,

sorry for writing several times in such a short time, but every start is
a little hard
When importing from PostGIS, v.in.ogr will remove the column with the
primary key and use the objects as cat. Is there a way to avoid this
behaviour, e.g a flag?
I just copied the table now in SQL, and imported the copy, but I guess
that is not really the best way to handle this.

During my search I found a post to the mailing-list from 2008 on this
issue, but no answer to that one.

Ah that makes sense,
I was trying to use it to generate, then remove a temporary layer for

I have changed my bash script with the following which now generates

That's a contradiction. Only lat/lon locations use degrees as the
coordinate system. A Mercator projection (whether normal Mercator,
transverse, or oblique) has coordinates in distance units (usually
either metres or feet).

A Mercator projection /can't/ have coordinates in degrees, as
coordinates have to be linear while Mercator has one coordinate vary
non-linearly with the angle from the tangent circle.

  my prompt looks like this:
 
  GRASS 6.4.1 (dem):~ 
 
  The reference to the location '(dem)' stays, even after changing to
  another location. How do I make Grass update this?

 The new environment variables are stored in the 
 $LOCATION_NAME/$MAPSET/.bashrc file (if you're using bash). But this file is 
 not 'source'ed when changing mapsets. So you need to do:
 eval `g.gisenv`
 source $GISDBASE/$LOCATION_NAME/$MAPSET/.bashrc

 or manually reset the prompt:
 export PS1=GRASS-6.4.2 ($LOCATION_NAME) \w  
There is no .bashrc file in the mapset directory, so I take it I would
have to set that up for each mapset in each location?

It's created when you start a GRASS session. There's no point in
creating it manually, as it will never be read, and will be
overwritten the next time you start a GRASS session in that directory.

Creating the .bashrc file in the mapset directory is something of a
hack. The startup script sets HOME
