Dear Users
We have recently downloaded Mapserver & MapLab software and configured
with IIS as well as Apache web server. We could successfully able to run
the demo application of MapServer in both the environments using the ESRI
shape file data. The application is able to do panning, zooming, querying,
layer control, etc. operations. Now as a part of second phase of the
project, we want to access the Oracle Spatial data from MapServer and
publish on browser. We made a trial but failed to achieve the objective. In
this regard, we have the following clarifications
(a) Does MapServer 3.6.3/4/5 support the Oracle Spatial Database?
(b) If the answer to above is "Yes" Could you elaborate the procedure for
setting up the configuration for the same.
(c) Has any body done coding to include this feature?
Any assistance in this regard in solving the above problem shall be highly
appreciated.
thanks and regards

Not really sure what you are asking but you can draw
a *large" polygon in the desired background color as
the topmost layer with a 'tranparent' polygon cutout for
the area you want the map rendered in
Or you can use mapscript to modify the image

I have a national raster weather map. I want to make state maps( using a

tell mapserver to show data only on the one polygon and nothing else?

Hi
If you have your querymap setup you can query the polygon
and have the query as selected.
# 2 querymap selected
querymap
color 255 255 168
size 740 740
status on
style selected
end
Cheers

Subject: [Mapserver-users] mapserver postgis query error (explain verbose)
I'm just checking to see if there's a fix for the Mapserver query of a
PostGIS layer that produces the "explain verbose" error included below. I
see PostGIS 0.7.5 was released last week -- there was some discussion
around this error earlier this month, but not sure whether this problem got
addressed in the new release.
My alternative solution was going to be pgsql2shp, so I'd also be
interested in anyone's success or frustrations with similar attempts.
thanks much, as always!
Content-type: text/html msPOSTGISLayerGetShape(): Query error. Error
executing POSTGIS SQL statement (in FETCH ALL): EXPLAIN VERBOSE SELECT *
FROM plant_coords - Error with POSTGIS data variable. You specified ''.
Standard ways of specifiying are :
(1) 'geometry_column from geometry_table'
(2) 'geometry_column from (<sub query>) as foo using unique <column name>
using SRID=<srid#>'
Make sure you put in the 'using unique <column name>' and 'using SRID=#'
clauses in.
For more help, please see http://postgis.refractions.net/documentation.php

Yes there is a fix. I sent it out to a few people last week and they
have indicated it works fine and hasnt caused any new problems.
It does leak about 1.5kb of memory/layer at the moment - this should not
be a problem for you. When I fix that I'll commit it to v3.6 CVS.
Until then, mappostgis.c is attached.
dave
ps. The 3.6 and 3.7 mappostgis.c used to be exactly the same. This is,
unfortunately, no longer the case - someone changed some of the map.h
fields and that required changes in "mappostgis.c". If you are using a
very modern mapserver, this mappostgis.c will not work. You'll know
right away at compile time if there's a problem.
It'll be a little bit before I merge in the 3.7 changes and commit it.

Subject: [Mapserver-users] another bug of mapserver 3.7
Right now we can chose band combination of a raster file by changing map
file with
"processing bands=x,x,x". But we can't change band combination by
php-mapscript.
There is no member in LayerObj that corresponds "PROCESSING".

I also got this error. It's related to using a C compiler to link C++ code.
I fixed it by editing the file Makefile and replacing 'LD = gcc' with 'LD

This particular droplet of knowledge did manage to wet my forehead, with
a little off-list help.
On further reading, it's clear, and it *almost* makes sense in the
Mapserver vs. Mapscript case. What I don't understand is when shp2png
which accepts explicitly layers to render with -l doesn't behave in the
same way as the CGI.
Thank you for the repsonse and thank you mapserver community for quite
fine software.

Jerritt,
saveImage() is long gone from the nightly MapScript. Use save().
Your script then would be something like:
#!/usr/bin/python2.1
import mapscript
def drawmap():
mymap = mapscript.mapObj("/usr/lib/cgi-bin/maps/europe.map")
mymap.width=600
mymap.height=400
myimage=mymap.draw()
# Just specify filename as argument to 'save', all other
# parameters come from the map's outputformat
save_result = myimage.save("euro.png")
# The Python way would be to raise an error instead of
# returning a value
if not save_result == mapscript.MS_SUCCESS:
raise IOError, "Could not save to euro.png in drawmap()"
drawmap()
Take a look at the latest (3.7) documentation regarding map
outputformats and you'll see how to set the transparency and
such to suit your needs.
Also, don't forget that the Python MapScript has a saveToString()
method which Perl has not. Comes in handy when you'd like to
have image data in memory rather than on disk.
image_string = myimage.saveToString()
cheers,
Sean

Subject: [Mapserver-users] Java API for MapServer?
Hello,
I've just discovered MapServer Open source WMS and I have an important
question for our business:
Is it possible to write java beans that manipulate Map Server Java =
objects ?
In other terms, a "MapServer Java Connector" (like ESRI ArcIMS Java
Connector) is (or will be) available?
Thanks a lot for your response.

Superb! works. The only documentation I could find was examples on this

Calling a function that doesn't exist certainly would produce a SWIG

This is a cool feature.... but it segfaults for me. I can't make much

Dendi,
some things about installing mapserver:
- do not use 'make install'. It will give you trouble when you compile a
newer
version of mapserver later, as this new version will then link against the
old libmap.a. Instead, just copy the mapserv executable to your cgi-bin
directory, and eventual mapscript flavours to their apropriate dirs.
- A guess that you do not need - in fact should not - copy or move libmap.a
and include files to anywhere. There are no applications that I know that
link against mapserver and thus would need this, and it might give you the
same problems as above mentioned when using 'make install'. AFAIK, the
mapserver/mapscript binaries are all linked statically against libmap.a, so
after compiling it is not needed anywhere. There are quite some posts about
people having weird troubles upgrading mapserver, till they found out that
some time long ago they once did 'make install' and that's why mapserver
did
not work anymore for them...
About getting started, there's a lot of documentation and examples on the
website. It all depends on what you want and how you intend to use
mapserver.
Please check that out.
Regards,
Vincent Schut.

Hi list,
where can I read more about "tiling a map"?
At the moment I use "gdaltindex", but the
tiffs and tfws are given to that procedure, so
I'm not able to have influence.
I want to tile a very big aerial picture with
a given worldfile into several smaller files
with correspondending worldfiles without
using ArcInfo or ArcView.
Is there any description available?
Thanks in forward,

Sven,
You can use gdal_translate for that. With the -srcwin flag you can
specify offset and width from the input image to be translated to the
output image.

Hi Folks,
I've been having great difficulty using the new style functions in
Mapscript 37.
I'm trying to extract a class object from the mapfile and change the
symbol size and color in php.
I have tried various adaptations of the mapscript 36 method but they are
quite dissimilar due to the new "style-type" instructions that 37 uses.
I've been working off the manual that Danielle (Morrisette) wrote for 37.
Here is part of the code, there are lots of different ideas in here from
other versions of mapscript but none of them seem to work,
$class = ms_newClassObj($layer);
//$class = $layer->getClass(0);
//printf("classname = %s",$class->name);
//printf("symbol under class =
%s",$class->get("symbol"));
//$class->set("symbol", "square");
$style = ms_newStyleObj($class);
$style->color->setRGB($rgb[r], $rgb[g], $rgb[b]);
//$class->set("color", $colorId);
$style->size = 1;
$style->symbol = 6;
//$class->set("size", 4);
if ($HTTP_FORM_VARS["CURRENT_PROG_ID"] == $ProgramIds[$iRow]||
($HTTP_FORM_VARS["CURRENT_PROG_ID"] <= 0 &&
$HTTP_FORM_VARS["CURRENT_PROG_ID2"] == $ProgramIds
[$iRow]))
{
$style->symbol = 2;
$style->size = 1;
//$class->set("size", 8);
}
else if ($ProgramCategory[$iRow] == 2) {
$style->symbol = 4;
//$class->set("symbol", 4);
}
else {
$style->symbolname = "star";
//$class->set("symbol", 3);
}
$style->outlinecolor->setRGB(0, 0, 0);
Am I on the right track with any of these? Any tips would be appreciated.

Masks are not directly supported, but this can be achieved using the
pasteImage() method in PHP MapScript. Search the archives for "mask"
and for "pasteImage" and you should find a few posts with examples.

Jerritt,
Since I've seen no segfaults from saveToString() on Win32, Linux,
or OS X, I suspect that it may be your GD library. What version
are you using? You will need version 2 of the GD library
to take advantage of many new features in the nightly (3.7)
MapServer. I'm using 2.0.11 and the MapServer developers are
using this, or more recent.
I have an interest in stomping out any bugs in the Python MapScript,
so if you sent me the trace I would look it over.
cheers,
Sean

I think a masking function would be a nice item to add to mapserver. Maybe
a
class item MASK where 1 is mask everything outside the area.
