AIMS AND SCOPE
The aim of Geomorphometry 2009 is to bring together researchers to
present and discuss developments in the field of quantitative
modelling and analysis of elevation data. Geomorphometry is the
science of quantitative land-surface analysis and description at
diverse spatial scales. It draws upon mathematical, statistical and
image-processing techniques and interfaces with many disciplines
including hydrology, geology, computational geometry, geomorphology,
remote sensing, geographic information science and geography. The
conference aims to attract leading researchers in geomorphometry
presenting methodological advances in the field and to provide young
researchers with an opportunity to present new results.

The Geomorphometry 2009 conference will continue a series initiated by
the Terrain Analysis and Digital Terrain Modelling conference hosted
by Nanjing Normal University in November 2006.

Possible topics include, but are not limited to:

- Extraction of land-surface parameters from DEMs
- Implications of novel data sources
- Identification and classification of land-surface objects
- Uncertainty in geomorphometry
- Semantics of land-surface description
- Visualisation in geomorphometry
- Implications of scale and resolution
- Flow and hydrological modelling using DEMs
- Efficient methods for application to large data sets
- Novel applications of geomorphometry
- Planetary geomorphometry

We specifically aim at papers with new methodological insights and
thus papers which simply describe the application of GIS are
discouraged.

CONFERENCE PROGRAMME
The conference programme will be based around a single track of
papers, all of which will be subject to review in the form of extended
abstracts by members of the programme committee. Criteria for paper
acceptance will include relevance to the conference, novelty,
scientific significance, relation to previous work in the domain and
the quality of presentation. A number of keynotes and open sessions,
led by outstanding experts in the field are also planned.

The proceedings will be made available both digitally and as printed
working materials to attendees at the time of the conference and
archived online. A special issue of Hydrology and Earth System
Sciences (http://www.hydrology-and-earth-system-sciences.net/index.html)
is planned, and selected authors will be invited to submit full papers
for review for this special issue.

WORKSHOPS
Three workshops entitled, "Automated analysis of elevation data in
R+ILWIS/SAGA"; "DEM analysis using ArcGIS toolbox"; "Back to reality -
Reconciling geomorphometry and geomorphology in the field" are
planned. Further details of workshops are available on the conference
web site.

KEYNOTES
We are delighted to announce that Professor David Mark, SUNY
Distinguished Professor in the Department of Geography at the State
University of New York at Buffalo and Dr Jo Wood, Reader in GI Science
at the Department for Information Science at City University, London,
have agreed to give keynote lectures at Geomorphometry 2009.

SUBMISSION
Prospective authors are invited to submit extended abstracts of up to
2000 words by the 24th of March 2009 (Extended deadline). Papers
should be prepared according to the following guidelines (Word
Document http://2009.geomorphometry.org/geomorphAbs.doc) (PDF
http://2009.geomorphometry.org/geomorphAbs.pdf). Papers must be
submitted as PDF through the EasyChair system at
http://www.easychair.org/conferences/?conf=geomorph2009. If you do not
already have an EasyChair account follow the onscreen instructions to
create one.

REGISTRATION
Registration will open on the 1st of March 2009. Early registration
rates for the conference (before 15th of May) will be 450 Swiss
Francs. Late registration rates will be 550 Swiss Francs.

[GRASS-user] errors in r.drain (develbranch)

[Guâno]

Hello all,

after a full SVN of develbranch, I'm getting errors in r.drain:

-
Errors in:
/home/guano/pessoal/tmp_install/gis/grass6_devel/raster/r.drain
--
In case of errors please change into the directory with error and run 'make'.
If you get multiple errors, you need to deal with them in the order they
appear in the error log. If you get an error building a library, you will
also get errors from anything which uses the library.

[GRASS-user] two questions - v.overlay and r.to.vect

[Guâno]

Dears,

I just stumbled across two issues here:

1 - v.overlay: can we make it to run also with points data? That is, I
want to "clip" extract some vector points using a polygon as limit. So
far it seems to work only with lines (6.5svn)

2 - r.to.vect: It would be nice if we could select which features to
be converted to vector by its categories, what do you guys think?

cheers

Carlos

[GRASS-user] Fwd: GMorph> ASTER GDEM is out

[Guâno]

-- Forwarded message --
From: Hannes Reuter 
Date: Mon, Jun 29, 2009 at 13:01
Subject: GMorph> ASTER GDEM is out
To: geomorphome...@yahoogroups.com




Dear geomorphometry people,

some really really good news today:
NASA/METI released today the 30m global (83degreesNS, ~22600 scenes)
ASTER GDEM based on 1,264,118 single ASTER dems from 1.4 million scenes
in total. 95% vertical ci: 20 meters, 95% horizontal ci: 30 meters)
see http://www.gdem.aster.ersdac.or.jp/

congratulations to NASA/METI to provide the worldwide community with
such a long awaited dataset. just a short additional note:

>> from website
Initial studies to validate and characterize the ASTER GDEM confirm that
pre-production accuracy estimates are generally achieved for most of the
global land surface, although results do vary and true accuracies do not
meet pre-production estimates for some areas. In addition, Version 1 of
the ASTER GDEM does contain certain residual anomalies and artifacts
that affect the accuracy of the product and may be impediments to
effective utilization for certain applications. Consequently, METI and
NASA acknowledge that Version 1 of the ASTER GDEM should be viewed as
“experimental” or “research grade.” Nevertheless, they are confident
that the ASTER GDEM represents an important contribution to the global
earth observation community.
<<

the link to the evaluation report will be probably be published
today/the coming days. as i/we had the possibility to evaluate 5 tiles
beforehand - from our analysis i/we can tell that you will run into some
of the following:
step anomalies across mosaicing edges,
mole runs,
sinks (we observed some down to 180m below the surrounding),
artifical mountains (up to 200m)
noise
non existing water mask
in case only a couple of images n<4 have been used also the horizontal
accuracy has some interesting features sometimes...

which certanly might or might not influence the calculation of your
terrain parameters. i know you all can derive your own conclusions.

all depends on your tile ... ;-)

data can be downloaded from JAPAN/METI at
http://www.gdem.aster.ersdac.or.jp/
or LP DAAC -> https://wist.echo.nasa.gov/~wist/api/imswelcome/.
restrictions of 100 tiles apply and only 16 connections at the same time
are allowed.so you might have to wait a bit.

cheers hannes...

Re: [GRASS-user] object-based classification (vs pixel-based)

[Carlos "Guâno" Grohmann]

AFAIK, SPRING, a GIS program developed by the Brazilian National Space
Research Institute, has excellent classifications algorithms. I once
heard that a comparison was made between several algorithms (including
e-cog), and SPRING was considered the best (don't know the title or
author of the article, though. sorry).

The problem is that SPRING is free as in free beer, not FOSS. But
TerraLib is FOSS, and pretty much everything that is implemented in
SPRING is being (or has been) implemented in TerraLib, so maybe here
is a way.

HTH

[GRASS-user] OFF-TOPIC - Earth Curvature in profiles

[Carlos "Guâno" Grohmann]

Sorry for the OT, but can anyone point me some reference (paper, web,
etc) that explains how can I draw a topographic profile using the
Earth´s curvature? I am thiking about the output of r.profile (ascii,
distance from origin + elevation), in a section of about 3000 km, with
a vertical exaggeration of about 200 times.

tks!

 Hello,

 I am chairing a capacity building workshop from 01-03 March 2008 in
Cape Town. The workshop is for young African scientists, and addresses
the use of ICTs for scientific applications.

 We have one track on remote sensing, which is to include the Bilko
free software for oceangraphy and coastal remote sensing data
manipulation, and with the output of this to be fed into GRASS as an
open source GIS.

 I urgently need assistance in finding someone who is available on
01-02 March and is willing to teach the segments on GRASS. Please can
you let me know who I should speak with.

 Thank you in advance for any assistance you can offer.

 Yours Sincerely,

Re: [GRASS-user] OFF-TOPIC - Earth Curvature in profiles

[Carlos "Guâno" Grohmann]

Well thanks all for the answers!

This is what I did:

- used r.profile to get (dist, elev) data from E-W profiles.
- I didn't considered the elipsoid, I used and approximation to a
sphere (to simplify my life :))
- from the total distance, I calculated the arc of curvature (theta)
- now I have a spreadsheet with my data (gnumeric)
- for the first point, I assigned a angular value of half the arc (theta/2)
- for each subsequent point, I subtracted the value of (theta/n) - for
n points in the profile
- then I created another column, with the "elev" value times 100 (for
vertical exaggeration) and added the radius of the Earth (6371 km)
- finally I created a polar plot of the distance and angles.

I not sure how "right" this is, but it seem to be a fair approximation.

Carlos

Hi, I just updated from svn, to test the new wxgui, but I got some errors:

GRASS 6.3.svn (amsul_wgs84):~ > Traceback (most recent call last):

[GRASS-user] Interpolation with faultlines?

[Carlos "Guâno" Grohmann]

I remember that some time ago, there was some discussion on
interpolation using faultlines. Any advances in that subject?

cheers

[GRASS-user] r.out.gmt -- color palette with gaps?

[Carlos "Guâno" Grohmann]

Hi all.
I have this color shaded relief map created with r.his and
r.composite. I want to use it as a base map in GMT, sou I went to the
AddOns page to get the r.out.gmt script, which creates the color
palette (.cpt) for me. But when I try to create the map with GMT, I
get this msg:


[EMAIL PROTECTED] grdimage america_sul_srtm30plus_shade_color.grd -JM15c
-R-56/-34/-26/0 -Camerica_sul_srtm30plus_shade_color.cpt > amsul.ps

grdimage: GMT Fatal Error: Color palette table
america_sul_srtm30plus_shade_color.cpt has gaps - aborts!


I remember using this script a while ago, and it worked fine..

thanks for any hint.

Carlos

[GRASS-user] circular neighborhoods?

[Carlos "Guâno" Grohmann]

Hello all.

I was thinking about the circular neighborhoods that r.neighbors use.
How exactly are they shaped? I mean, in a 3x3 window, does the
circular one looks like a cross? and then it start to look more like a
circle as the size increases?

cheers

Re: [GRASS-user] circular neighborhoods?

[Carlos "Guâno" Grohmann]

Yes, Eric, that is what it does for a _square_ neighborhood. I am a
little confuse about the actual shape of the _circular_ neighborhood.

using your examples:

will a 3x3 circular neighborhood look like this:?

---o---
o-X-o
---o---

and a 5x5?

---o-o-o---
o-o-o-o-o
o-o-X-o-o
o-o-o-o-o
---o-o-o---


maybe now my question is more clear...



thanks


Carlos

Re: [GRASS-user] Interpolation with faultlines?

[GRASS-user] GRASS tutorial in Portuguese (pt-br)

Hello all.

This is just to announce that a new tutorial is available, in
Brazilian Portuguese (pt-br). I wrote it over the last year, and
"tested" it in short-course I gave last week. The plans are to keep
updating it, with new sections and errors corrections. Some of it is
based on the GDF tutorial (Dassau et al), and some is based on my own
experience.

enough disk space...

here is the output:

[GRASS-user] a few suggestions and questions

[Carlos "Guâno" Grohmann]

Hello all

first I'd like to make a few suggestions to enhance (IMO) our favorite GIS:

- normalize the options in all modules. I noticed that while most
commands take "--overwrite", some (r.neighbors) use "-o"
- some modules require a dummy value when output a list (r.mask,
r.proj, v.proj..). Is this really necessary? this is a very confusing
option (specially for newbies).
- also, I think that _all_ fields (gui speaking now) where a
raster/vector map is to be entered should have the select button, no
matter if it is a field for new maps, because it makes the whole thing
consistent, and it is easier for new users to understant how things
work.

now some issues:

is plan curvature in r.param.scale broken? I can't get a map of it.
profc works fine. Also is it possible to make r.param.scale work in
latlong regions? (please?)

this is just out of curiosity:

if there are too many points to be used for interpolation by RST, how
does it chooses which points will be used?


thats all for now,

cheers

Carlos

  What do you say that is impossible? Using Wood's approach in LatLong
regions or using a window larger that 3x3?
The module's _intention_ is to provide multi-scale analysis, by means
of different window sizes.

[GRASS-user] geoid data from TOPEX

[Carlos "Guâno" Grohmann]

Hello all.

 I downloaded some geoid data from
ftp://topex.ucsd.edu/pub/global_geoid_2min/
there are three files:

geoid.egm96.grd 
geoid.img.9.2 
geoid.img.9.2.ers

the grd is a GMT grid with 7.5min spacing. The other is a ERMapper image
file with 2min resolution. I managed to import geoid.img.9.2 with r.in.bin:

r.in.bin -s -b input=/home/guano/geodata/TOPEX/geoid.img.9.2
output=geoid.img bytes=2 north=90 south=-90 east=0 west=360 rows=6336
cols=10800 --overwrite

but there is a shift in position. When I compare with vector data for
continents limits, I see that it is shifted to north. (see attached)

Anyone have used this data?

cheers

[GRASS-user] RST - how does it chooses from near points?

[Carlos "Guâno" Grohmann]

It just came to me: if I have a vector map to be interpolated by RST,
how does the algorithm chooses between points that are very close to
each other?
And if I have more than one point with the same coordinates, but
different values?

Re: [GRASS-user] GUI equivalent of command

[Carlos "Guâno" Grohmann]

Can I ask _where_ in your screen is gGis-manager?

I taught a short course on GRASS a few months ago, and I noticed that
most students would let gism on the right side of the screen and the
display on the left (not sure why)

The thing is that all menus will open to the right, so the best
placement for gism is at the left of the screen, otherwise you may get
some behaviors like you are describing.

cheers

Re: [GRASS-user] GUI equivalent of command

Nikos,

In this case it depends on _how much_ to the left you gism is. If it
is too close to the screen border, you can get problems as more levels
of sub-menus are opened to the right.

Maybe wx provides a way of the gui be more "smart", and open the menus
to the right or to the left depending on the position of gism?

Re: [GRASS-user] Is the SRTM dataset a DEM or a DSM?

[Carlos "Guâno" Grohmann]

IMO its a DEM, since the "z" value represents elevation, including
tree canopy and urban features. I personally don't like the term DSM
because it can be related with any kind of Surface, and DEM (and DTM,
when the "z" values represent the altitude) is related with the
_topographical_ surface.

[GRASS-user] errors compiling on Zenwalk

[Carlos "Guâno" Grohmann]

Hi all,

I'm trying to compile latest svn in Zenwalk 5.2 (Slackware based), but
I got lots of errors. The first module of the error list was d.ask, so
I went to run make inside it:

Thanks for your help, Glinn, but it doesn't look like I have more than
one libpng installed:

root[guano]# netpkg list |grep installed |grep png
[I][l] Found installed libpng-1.2.27-i486-1.tgz on the repository

[GRASS-user] Re: errors compiling on Zenwalk [Solved]

[Carlos "Guâno" Grohmann]

Just to update you all. I fixed the problems by removing my old
grass_trunk dir and doing a new svn checkout.

I changed the OS (from Ubuntu to Zenwalk), so there were some
leftovers related to ubuntu..

cheers

Re: [GRASS-user] v.in.ogr weird import

[Carlos "Guâno" Grohmann]

Christian, if you shapefiles and you region are with the same
projection/coordinate system, the -o flag is not necessary.

also, the "dsn" option must point to the _directory_ were your shps are. like:

v.in.ogr dsn=/home/poseidon/Work/vector_data/ output=tracklines2
layer=Tracklines2.shp min_area=0.0001 snap=-1


hope this helps

Carlos

[GRASS-user] Trend-surface analysis with GRASS+R: did something changed in sp package?

This is where I stopped. I had these steps from emails in this list,
and I remember they used to work. Has anything changed I am not aware
of?

[GRASS-user] create 3d plane from vector lines

[Carlos "Guâno" Grohmann]

Hi all,

I'm stuck here, trying to create 3d vertical surfaces from 2d vector
lines (to represent faults in nviz). hints?

TIA

Carlos

Re: [GRASS-user] create 3d plane from vector lines

[Carlos "Guâno" Grohmann]

Hello José.

v.surf.rst is not exactly what I want here, although I could duplicate
my vector lines with different elevations and then interpolate the
values to get _raster_ surfaces. I was thinking more in a v.extrude
way, just that it currently extrude areas to form facets or shifts
lines, but it doesn't create planes from line (AFAICT).

cheers

Carlos

Thanks Soren, I got the effect I wanted in Paraview, using the "linear
extrusion" filter.

Re: [GRASS-user] create 3d plane from vector lines

[Carlos "Guâno" Grohmann]

Hey Mate,

you know, simple dipping surfaces are easy, r.plane will do the job,
but _complex_ dipping surfaces (like real faults) are still a work in
progress..

cheers

[GRASS-user] Fwd: 1st Call for Papers: Geomorphometry 2009, 29 August - 2nd September, Zurich, Switzerland

[Carlos "Guâno" Grohmann]

Apologies for cross postings

FIRST CALL FOR PAPERS

Geomorphometry 2009

29 August - 2 September 2009

Zurich, Switzerland

http://2009.GEOMORPHOMETRY.ORG

e-mail: [EMAIL PROTECTED]

PROGRAM CHAIRS

Ross Purves University of Zurich

Stephan Gruber University of Zurich

Tomislav Hengl University of Amsterdam

KEY DATES

Workshop proposals due 14 January 2009

Extended abstracts due 1 March 2009

Notification of acceptance 1 April 2009

Final camera-ready digital manuscripts due 1 May 2009

Author registration deadline 15 May 2009

Early registration deadline 15 May 2009

Geomorphometry 2009 Workshops 29 August & 30 August 2009

Geomorphometry 2009 31 August - 2 September 2009

AIMS AND SCOPE

The aim of Geomorphometry 2009 is to bring together researchers to
present and discuss developments in the field of quantitative
modelling and analysis of elevation data. Geomorphometry is the
science of quantitative land-surface analysis and description at
diverse spatial scales. It draws upon mathematical, statistical and
image-processing techniques and interfaces with many disciplines
including hydrology, geology, computational geometry, geomorphology,
remote sensing, geographic information science and geography. The
conference aims to attract leading researchers in geomorphometry
presenting methodological advances in the field and to provide young
researchers with an opportunity to present new results.

The Geomorphometry 2009 conference will continue a series initiated by
the Terrain Analysis and Digital Terrain Modelling conference hosted
by Nanjing Normal University in November 2006.

Possible topics include, but are not limited to:

- Extraction of land-surface parameters from DEMs

- Implications of novel data sources

- Identification and classification of land-surface objects

- Uncertainty in geomorphometry

- Semantics of land-surface description

- Visualisation in geomorphometry

- Implications of scale and resolution

- Flow and hydrological modelling using DEMs

- Efficient methods for application to large data sets

- Novel applications of geomorphometry

- Planetary geomorphometry

We specifically aim at papers with new methodological insights and
thus papers which simply describe the application of GIS are
discouraged.

CONFERENCE PROGRAMME

The conference programme will be based around a single track of
papers, all of which will be subject to review in the form of extended
abstracts by members of the programme committee. Criteria for paper
acceptance will include relevance to the conference, novelty,
scientific significance, relation to previous work in the domain and
the quality of presentation. The proceedings will be made available
both digitally and as printed working materials to attendees at the
time of the conference and archived online. A special issue of a
journal, to which authors will be invited to submit full papers after
the conference is also planned.

WORKSHOPS

Geomorphometry will host up to three workshops, each with 15-30
attendees on the 29th and 30th August. We invite applications to host
a workshop on a theme related to the main conference. Workshops should
primarily take the form of either tutorials in a particular method or
technique, or provide the opportunity for detailed discussion of
upcoming topics. They should not simply be mini-conferences. If you
are interested in organising a workshop, please mail
[EMAIL PROTECTED] with WORKSHOP as the subject line, as well as
a 1-page description of the workshop with the following headings:
intended aims and scope, intended audience, outline workshop programme
and technical requirements.

SUBMISSIONS

Prospective authors will be invited to submit extended abstracts of up
to 2000 words by the above deadline through the EasyChair system.
Formatting instructions and detailed information on using the
submission system will be available in due course. Extended abstracts
must be original works by the authors, not be currently under review
in the same form by another outlet and not submitted elsewhere prior
to the notification date.
