Hi,
I am trying to convert my shape files to postgre files. After getting sql
file, postgre got struck by not recognising addgeometrycolumn function.In
one of my files--
SELECT AddGeometryColumn('','gisdb','the_geom','-1','MULTILINESTRING',2);
works while in other

Hi,
I want to display a tool tip for the polygons in my application for which I
need lat-long values of polygon. Please tell me how to retrieve the values
from geometry type field of postgre or If there is any other way of doing
this.
Regards
Mukul

Probably dont understand what exactly you are trying to achieve here but it
is not as simple as map.getLayer(0) to get the topmost layer? And once you
have the layer object use one of the query function to select the record?
E.g. myLayerObj.queryByPoint ?

Hi,
I have problems with some layers and I'm thinking that the reason is the
number of records.
For example, with a layer which has 63057 records, the result is the
following:
500 Internal Server Error
And Apache log error:
Timeout waiting for output from CGI script /var/cgi-bin/mapserv

There is no limit for number of records in Mapserver. Apache. that is used as

tell much about how hard that layer is to handle, if
Hi Iratxe,
I've found that the limit on my maps is 2000 records.
I store the points in a MySQL database and use PHP/MapScript to create the
map so I don't know what sets this limit but 2000 points on a map seems fair
enought for the average map.
Unless you have a very big map it would quickly
Hi,
I made a quick test by commenting out my MAXSCALEDENOM and MAXFEATURES
settings. For me it takes now around 10 seconds to draw 1.1 million polygons
from Oracle spatial through WMS. Timing comes from Mapserver log with layer set
to DEBUG 5. Sure it does not make sense to draw 1.1 million
Thx Umberto, I'll try to reinstall GDAL then, thx :).

Hi Charlotte,
This is a known issue with PHP Mapscript. With the way the object are
currently made, complex objects (that have references to other object, like
mapObj) are not properly freed when we delete the php object. Note that the
memory is well freed as soon as the php script ends.
Hi meenu,
MapServer returns an image to your browser. At this point, there is no more
layers. That's only an image. You cannot bind any browser mouse event to a
specific country or area. You would need OpenLayers + a Vector layer to do
that.
Thanks,
Alan

If you only need to create your map as a static image (with no pan and
zoom), you could use MapServer to generate a html imagemap. See the
documentation here: http://mapserver.org/output/imagemaps.html
Most people these days are using openlayers http://www.openlayers.org or
another javascript
Paul,
I would guess that this really is about the client-side map interface and not
about MapServer. Does your interface only allow them to click/select the
topmost layer? Do you pick which layer is selectable? Do you let them pick
which layer is selectable? Is it random?
Tells us
If you're doing point queries MapServer/MapScript can do this for you.
You do a
mapObj.queryByPoint with the MS_SINGLE mode and then the function will
identify
the closest feature (considering TOLERANCEs!) in the top-most ACTIVE
layer.
This site uses this to it's advantage...
Hi David...
In my system the user SELECT the active layer (dropdown), and so he can
query it selecting a a area or a point
But, I´d like to take off that dropdown to select active layer... And when
user click on map to query, I figure out what layer was clicked and query
that...

Hi all,
I am investigating different options on using 3D with MapServer.. There was
once an application called Open3DGIS (http://open3dgis.sourceforge.net/), which
doesn't seem to live anymore.
Are there any other tools / addons that are alive in this field?
Thanks!

Hi Matej,
Take a look at osgEarth (http://osgearth.org), a toolkit that renders
open-standards data (from WMS, MapServer, TileCache, etc.) in 3D using the
open source OpenSceneGraph library.

Hi Steve!
I didn't know that mapObj could call queryByPoint as well ... Thanks...
But, How can I get the feature selected after query ?
Using LayerObj I did that (using layer.getNumResults() )

You just need another loop...
for( ...each layer...) {

... now your getNumResults() loop ...

Hi Tom-
Very strange. I don't see an xml file but now I've tried this and I do
get an instance of an imageObj back:
my $map = new mapscript::mapObj('test.map') or die no map $!;
$map-saveMapContext('test.xml');
my $image = $map-draw();
print $image;
So I guess I'll proceed and see how things go.
How can I precache tile images from shapefiles?
Thanks

Hi people,
I used gdal_translate in the GRIB file I want to show with mapserver,

Hi there!
There is nothing wrong with your block X and Y size (161x1). It indicates that your data is not
tiled/blocked, so it is most likely to be read row by row. If the image looks strange is not because
of that. You have 98 rows in 0.02 degrees, so if it looks like a line, I wouldn't be
Hi,
I use a combination of server code and Javascript.

Your request is somewhat lacking in detail, but assuming that your
goal is a simple one, here is one way to accomplish this.
1. Create a MapServer project that displays your shapefile in whatever
style you choose.
2. Setup a TileCache instance that points to your MapServer project.
3. Run the
