Subject: [Freegis-list] Compile shapelib (shared) on Solaris
Message-ID: <3D232730.91102556@na.teleatlas.com>

I'm trying to compile shapelib 1.2.9 as a shared library on a Solaris
system and am getting an error.  I use the command "gmake lib".  I can
"gmake" with no problem, but I understand I need to make the shared
version to use with gen2shp.  Alternatively, I would be happy to modify
gen2shp to link statically if someone can point the way.  Thanks!

The result:

I tried on:

| cheops shapelib-1.2.9 64: uname -a
| SunOS cheops 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-1

and no serious problem occured.
You should make sure to use the CC=gcc and the correct ld.
For the latter you might try to manually execute:

| ld -G -h libshp.so.1 -o .libs/libshp.so.1.0.1 shpopen.lo shptree.lo dbfopen.lo  -lc

instead of using the makefile-executed version:

| /usr/bin/ld -G -h libshp.so.1 -o .libs/libshp.so.1.0.1 shpopen.lo shptree.lo dbfopen.lo  -lc

Hi,

I am using VMAP0 and I would like to centre the map on
the Pacific Ocean. My question is : do I have to
convert all the longitude coordinates in order to have
data ranging between 0 and 360 degrees (for example)
or is there another way to proceed ?
Thanks in advance !

it depends on the tool you are using. Usually
it does the job for you to shift/center/zoom to
the map as you wish.

Message-ID: <3D2D8BB3.94F02745@na.teleatlas.com>

Hi Jan,

I had already added the line "CC = gcc" to the Makefile.  I tried the 'ld' command by hand as you
suggested (after the 'gmake lib' failed) and it executed without complaint.  My path points me to
/usr/ccs/bin/ld.
I also got a suggestion from Chris Bell to make sure I had the version of libtool for Solaris, so
I downloaded and installed libtool 1.4 from sunfreeware.com. The errors were still the same.

However, it appears that the error message stems from the Makefile line:
  /bin/sh libtool --mode=link gcc  -g -O2  -o libshp.la -rpath /usr/local/lib \
  -version-info 1:1:0 shpopen.lo shptree.lo dbfopen.lo

When I execute this line by hand I get the same error messages:

boston% /bin/sh libtool --mode=link gcc  -g -O2  -o libshp.la -rpath /usr/local/lib -version-info
1:1:0 shpopen.lo shptree.lo dbfopen.lo
rm -fr .libs/libshp.la .libs/libshp.* .libs/libshp.*
gcc -shared  shpopen.lo shptree.lo dbfopen.lo  -lc  -Wl,-soname -Wl,libshp.so.1 -o
.libs/libshp.so.1.0.1
ld: warning: option -o appears more than once, first setting taken
ld: fatal: file libshp.so.1: cannot open file: No such file or directory
ld: fatal: File processing errors. No output written to .libs/libshp.so.1.0.1
collect2: ld returned 1 exit status

So libtool apparently performs the 'rm', and calls gcc with the -shared flag and flags telling the
linker to make the shared object libshp.so.1, and a final output file from gcc of
.libs/libshp.so.1.0.1.  I assume that 'ld' is being called by gcc.  Unfortunately I can't seem to
find a way to see exactly what is being passed to ld.  Giving gcc the -v flag showed me the syntax
of collect2, which apparently calls ld, but still no clues.

Any other ideas?

Thanks,
Eric

Subject: [Freegis-list] Mobile positioning
Message-ID: <02071912305304.18324@janacek>

Hi,

I would like to ask if anybody knows if nowadays exists any
solution how to get position of mobile phone (GSM) calculated 
in the phone (J2ME), that means not as a service provided by
an operator. Probably E-OTD as described here:
http://www.wirelessdevnet.com/channels/lbs/features/mobilepositioning.html

I.e. exist any mobile phone with J2ME supplied with java classes
which may be used to get information about base stations around
and distance (time) to that stations (say that I know the position
of base stations, which I don't of course)?

I found this: http://www.jcp.org/jsr/detail/179.jsp
which is interesting, but just at the beginning.

Exactly what I don't want seems to be supported well by:
http://www.ericsson.com/mobilityworld/sub/open/technologies/mobile_positioning/index.html


Any information, experience or links are appreciated.
Are there other suitable mailing lists I could ask for this?

Thanks.

Radim

Yours is way too vague a question.

They are used extensively in all sorts of GIS applications, and in the
algorithms used to do internal geometric calculations. Indeed, since
they are a fundamental mathematical construct, it would be hard to make
any GIS that did not in some way use them. 

good luck,

Hmmm, may be I will have asked a better question if I knew

I have seen many GIS applications in the forum, and on the freegis.org
pages.
However, I am yet to find one which really uses the Voronoi algorithm. I
came
across this while reading the "dying" GFC library, and wishes to know more.
In fact, neither OpenEV, MapServer etc are using it so by your write up you
do not consider these are GIS applications?

Please, I really need the help - which open source systems are using this
algorithm
so that I could find out more?

Best regards,
Paul.

Hi,

GRASS is providing "s.voronoi":
http://grass.itc.it/gdp/html_grass5/html/s.voronoi.html

former versions were also providing "v.geom" but due to
license problems this code was removed from GRASS.

Source code is here:
http://freegis.org/cgi-bin/viewcvs.cgi/grass/src/sites/s.voronoi/
(or you download the full source code)

Hope this helps,

 Markus

perhaps your ld simply does not to work as it is assumed by gcc.
As it works fine over here, I suggest you switch to a complete
set of GNU tools including the ld.

Maybe you system adminstrator can help to resolve the problem.

Dear Paul,

As my knowledge, Voronoi used for creating TIN (Triangle Irigular Network)
in GIS. This is a function of some GIS system, with this, you can creat 3D,
or vitural terrain, contour interpolation...

any GIS that did not in some way use them.

good luck,

Hmmm, may be I will have asked a better question if I knew
what it is.

I have seen many GIS applications in the forum, and on the freegis.org
pages.
However, I am yet to find one which really uses the Voronoi algorithm. I
came
across this while reading the "dying" GFC library, and wishes to know more.
In fact, neither OpenEV, MapServer etc are using it so by your write up you
do not consider these are GIS applications?

Please, I really need the help - which open source systems are using this
algorithm
so that I could find out more?

Best regards,
Paul.

Hi,

GRASS is providing "s.voronoi":
http://grass.itc.it/gdp/html_grass5/html/s.voronoi.html

former versions were also providing "v.geom" but due to
license problems this code was removed from GRASS.

Source code is here:
http://freegis.org/cgi-bin/viewcvs.cgi/grass/src/sites/s.voronoi/
(or you download the full source code)

Hope this helps,

 Markus

Hi Folks,

I've released two API's under the copyleft MPL 1.1 to use
the well known Proj4 library under Borland Compiler ware.

Unfortuanlly I've to change code to prevent the use of
enviroment variables line in UNIX. So you can explicit
name the directory where your projections are situated.

The code come with two samples C++ and Delphi.
For the BCB I've written a small class container for
the coordinate transformations. You can download
the stuff under

http://www.triplexware.huckfinn.de/geogfix.html#proj

Have fun and bye Alex.

Subject: [Freegis-list] OpenMap 4.5.3 has been released!
Message-ID: <CBC698FB-A001-11D6-9D3E-000393033D5C@bbn.com>

We've released version 4.5.3 of OpenMap(tm) at

         http://openmap.bbn.com

(Note: OpenMap 4.5.1 was a customer release created on July 23.  OpenMap 
4.5.2 was a false start (no javadocs). All functionality found in 4.5.1 
is available in 4.5.3, with a few extras including the javadocs.)

OpenMap is open source software.  New for this release:

         * Added the com.bbn.openmap.tools.dnd package that contains a
         global application mechanism for handling Drag and Drop events.

         * Added Oliver Hinds' OMColorChooser preview panel, so you can 
see
         what the color looks with the transparency setting before you hit
         OK.

         * Incorporated Raj Singh's updates to the WMSPlugIn, which bring
         it into compliance with WMS specification version 1.1.0, 
including
         some error handling and JPEG image quality requests.

         * Incorporated Lonnie Goad's updates to the EsriPlugIn, which
         improved GUI interaction, table interaction, and provided tool
         tips over OMGraphics on the map that reflect the DBF contents for
         that graphic.

         * Fixed problems in the com.bbn.openmap.dataAccess.shape package.
         The ShpOutputStream was putting in the wrong record number
         (started at 0 instead of 1), and fixed a couple of problems with
         export, including a problem with handling embedded lists, and
         translating DrawingAttributes from OMGraphics that were converted
         to EsriPolygons and EsriPolylines.

         * Added ProgressEvent, ProgressListener and ProgressSupport
         classes to the com.bbn.openmap.event package.  These objects
         provide a way for a component to let someone else know how much 
of
         a task is done.  This has been integrated into the MakeToc class
         in the RPF package.

         * Added a 'matted' property in the OMGraphic object.  If
         setMatted(true), then the OMGraphic gets drawn with a thin, 1
         pixel black line around it.  Makes it more distinctive, 
especially
         in busy backgrounds.

         * Changed the graphicLoader package, making it much more
         significant.  The GraphicLoader is an interface, representing an
         object that creates OMGraphics from some source and sending it to
         a receiver that will rendering it on a map.  The
         AbstractGraphicLoader is an OMComponent that contains all the
         basic GraphicLoader functionality, along with the basic ability 
to
         use the MapHandler to find objects and being a PropertyConsumer,
         so it's ready to be initialized with properties in the
         openmap.properties file.  The MMLGraphicLoader is additionally
         prepared to receive MouseEvents.  The LOSGraphicLoader is the old
         GraphicLoader that lets things wander on the map, while keeping
         track of what objects are in LOS of each other.

         * Made modifications to OMGraphics.  Made the OMLine handle arrow
         heads properly.  Made arrow heads bigger.  Made OMGrid more
         consistant and fixed bugs in column and row handling.  Added an
         empty sort() method on OMGraphicList which can be extended with
         customized sorting criteria.  Added a sort action constant mask 
to
         OMGraphicConstants.  Added setSelected() and isSelected() methods
         to OMGraphic.

         * Added better trapping for SVGFormatter errors in the FileMenu.

         * Added the OMComponent, which is a MapHandlerChild and a
         PropertyConsumer, reflective of an object being added to the
         openmap.components property of the openmap.properties file.
         LayerHandler was changed to extend it.

         * Modified Environment.java to handle internal frames
         independently of being in applet mode.

         * Modified the build.xml file.  The OpenMap package builds things
         differently, too.  First, all compiled classes are placed in the
         classes/openmap directory, except for the CORBA classes which are
         placed in the classes/corba_vb directory.  Second, all of the
         openmap classes are placed in the openmap.jar file.  
omcontrib.jar
         and omcore.jar are no longer created.  All of the CORBA classes
         are placed in the omcorba_vb.jar if the corba build target
         (visibroker) is created.

         * Added Jakarta Ant 1.4.1 to the OpenMap package, making OpenMap
         pretty much self-compiling.  All of the infrastructure for the
         original Makefiles have been removed, and replaced with Makefiles
         that call ant.

         * Modified the build.xml file to handle the corba classes better.

         * Created the MakeTocException, and the
         com.bbn.openmap.layer.rpf.MakeToc class now throws that exception
         instead of calling System.exit(), in case it is embedded into a 
GUI.

         * Misc bug fixes in several classes, fixing null pointer
         exceptions, security access exceptions, etc.

         * Modified the EsriShapeExport class so that a GUI is not brought
         up to save the files if a file path is provided.

         * Fixed a bug in OMPoly that prevented internal Shape objects 
from
         being created if soShapes == false.

See http://openmap.bbn.com/com/bbn/openmap/ChangeLog for a list of 
changes.

OpenMap is a JavaBeans-based toolkit for building applications and

Hi,

I am looking for some C codes for calculation of
eigenvalue and eigenvector of a general matrix and
I am very appreciated if you can give me some hints.

Thanks a lot

Ruisheng Wang

I am sorry, but you've hit the wrong mailing list
for your question.

A google search with "eigenvalue eigenvector C code"
will deliver numerous links exactly on what you are
searching for.

Best

Hi Ruisheng Wang,

you may study the file:

GRASS 5.0
./src/libes/gmath/eigen.c

which contains a function to calculate eigenvalues and eigenvectors.

CVS HTML interface URL:
http://freegis.org/cgi-bin/viewcvs.cgi/grass//src/libes/gmath/eigen.c?rev=1.2&content-type=text/vnd.viewcvs-markup

Maybe helpful?

Cheers

 Markus

Subject: [Freegis-list] FreeGIS CD 1.2.1
Message-ID: <20020731205524.GA3477@intevation.de>

Dear FreeGIS folks,

the FreeGIS-CD 1.2.1 for GNU/Linux systems has just been released.

Below is our official press release.

I hope we'll be able to keep the update interval since the Free GIS Software
developer community increases their pace towards integration and
new developments.

All the best

	Jan



	FreeGIS-CD 1.2.1 for GNU/Linux systems released

  Meanwhile in its nineth edition (v1.2.1) the FreeGIS-CD offers again an
  updated and enhanced collection of geographic information procession
  capabilities to GNU/Linux distributions.

Osnabr?ck 31st of July 2002.

In a reduced interval of 3 months Intevation GmbH publishes
the FreeGIS-CD (v1.2.1) in its nineth edition.

The CD presents a collection of GIS applications, libraries and data
sets in current versions. It contains e.g. GRASS, MapServer,
gdal, PROJ und GLOBE. With Thuban now a simple viewer of geodata for the
visualisation of shapefiles is included.

The FreeGIS-Tutorial (in german language) explains how to do common GIS
task with Free Software. It is included on the CD in its HTML- and
PDF-Version. Printed copies are available separatly. The documentation on
the CD lowers with easy comprehensible commands the entry barrier towards
the GIS applications.

The now published FreeGIS-CD was tested on the major Linux based
GNU-Systems RedHat, Mandrake, Suse and Debian. 

"Free GIS Software has a high potential due to its great power and
flexibility. Both the development and the integration of the different
components progresses continously", explains Dr. Jan-Oliver Wagner who is
responsible for the publishing of the FreeGIS CD at Intevation. "We bear in
mind this high dynamic by actualising and enhancing the FreeGIS CD
regulary."

The FreeGIS-CD v1.2.1 can be ordered for 30 Euros
through Intevation GmbH and ships out of Germany and North America.
