[GRASSLIST:1023] problem with compiling grass 5.4 source

GRASS GRASS user
1

Hello,
I have a problem with configure procedure in grass 5.4 and grass 5.7.
My system is a Fedora 5 with all sources of grass needed packages.
When i run ./configure with or without all options set the configure program exit with error when execute 'checking system version (for dinamic loading)... ../../grass-5.4.0/configure: line 12492: syntax error: unexpected end of file.

I have the same error with tcl/tk 8.3.5 and 8.4.9 but 8.4.13 is ok.

Please help me!!!!

Thank's
Simone Pittaluga

Ciao Simone,
here you can find RPMs for Fedora 5 of the latest stable version of
GRASS (6.0).

http://ftp.gwdg.de/pub/misc/freegis/intevation/freegis/fedora/5/RPMS/

Don't know if it can help you, but you should in general use this
version.

Ciao,
Steko

Please post your exact ./configure syntax and the error.

I have the same error with tcl/tk 8.3.5 and 8.4.9 but 8.4.13 is ok.

Use 8.4.13 then?

Note 5.7 is old. Don't use it. 6.x is it's continuation, but much more
developed and bugfixed. Use 6.0.2 at least (or 6.1 CVS preverably, 6.2
coming soon).

I now use tcl/tk 8.4.13 and i compile that without problem. (the problem was the same of grass)

I have a lot of data to share and other system run grass 5.4 and i need to use the same version.

Thank's for help

Iv a mapset with a lot (200) of point. Every point is a pollution indicator (a tree, a bush...) with many informations, one of these is a lichens biodiversity index.
What i want to do is to interpolate this index value to obtain a map of biodiversity of the city covered by the survey.
Iv done the interpolation (with no so good results) but now i need to cut the raster obtained around the external points... maybe i have to do something like a buffer around the external points of survey and cut the map obtained from interpolation. How can i do that without have 'holes' in the internal part of the map? is there a way to do that?

Sorry for my English

Here's an automated way:

v.hull input=points output=point_hull
v.to.rast input=point_hull output=point_mask use=val value=1
r.mapcalc "interp_trim = if( isnull( point_mask), null(), interp_values)"

where interp_values is the raster interpolation of your points.

You may find that v.hull doesn't do a good enough job of outlining
your data points. In that case, you will need to edit the vector
created by v.hull to something you like better.

Hope that helps,

David

If you work with v.surf.rst parameters, you should be able to get very good
results for your interpolation.

As you imply, however, you can sometimes get better (or more accurate)
results if you limit the raster interpolation to the area of the points. You
can do this by calculating a convex hull around the points. This is the
minimum polygon that will contain all the points. You can create a convex
hull in GRASS with v.hull.

Use v.to.rast to convert the convex hull to a raster map. You can use
v.buffer to expand the convex hull a bit before you convert or use r.grow
to expand it after you convert to raster. Then specify this raster as a mask
in v.surf.rst. The resulting interpolated map will only exist in the area of
the points.

Hi people,
I created a raster map in a xy location and I georeferenced it with: i.group,i.target,i.points,i.rectify.
now I'd like to use the same raster in my gaussboaga location but I don't know how to import it in this location, could you help me please?!
I tried to export the map and then to import it from the new location but it didn't work :frowning:
thanx,
Riccardo

If your raster requires reprojection, use r.proj. It will move it from
one location to another warping as needed.

If the raster is already projected in "gaussboaga", just change the
projection of your xy location, where the raster is stored, to
"gaussboaga" - g.proj.

Thanks for your help...
I tried using v.hull but the result wasn't what i hope... v.hull create a vector containing a polygon, a centroid and an area object... the command works fine but i need to obtain a more precise job... what i need is a polygon that connect all the external points without to calculate (like v.hull do) the minor length for the polygon.
Is there a way to obtain this?

besides, i had some problems buffering the vector polygon that iv created with v.hull... using the v.buffer on the vector with a buffer-value more than 70 meters i obtain a strange figure with a hole and too much centroid... any idea?

I understand the problem you are having. What we need is a v.hull with
a tension parameter so that it sticks closer to the data points.

Anyway, try this:

1. Buffer your data points with a sufficiently wide buffer that the
internal data area merges together into a single polygon. Note the
buffer distance.

2. Convert the polygon to a raster with a value = 1

3. Select all cells that are null (i.e., outside the data area)

4. buffer the "no data" area to trim off the excess data region
created in step 1. The idea is to cut back into the data region about
the same distance you buffered in the first place

5. Select all the null cells in step 4 (the data region) and make this your MASK

6. Trim the interpolated map by the MASK created in step 5.

besides, i had some problems buffering the vector polygon that iv
created with v.hull... using the v.buffer on the vector with a
buffer-value more than 70 meters i obtain a strange figure with a hole
and too much centroid... any idea?

see the v.buffer help page, there are some bugs.

Try using a smaller buffer size multiple times. (35m twice)

I wrote a script that calculates a rough distance from any non-null
data in a raster. You can use it like a buffer. It may work better on
a large data set than v.buffer since it is just making a special call
to r.cost.

Search the Wiki Add-ons for r.eucdist
