Hi
Daniel,
I'm not sure if mapserver can do this for you; how I did it was to
create two different shapes, and use the minscaledenom and
maxscaledenom to display one of the two in different scale levels.
Cheers,
Tom

Hi,
If you data are in a database it should be possible to take them out through
simplify function. For PostGIS see
http://postgis.refractions.net/docs/ST_Simplify.html
You should define the layer DATA in the mapfile with simplifying factor as a
variable and then make OpenLayers to send the

guys help me looking at this configuration and tell me whats wrong?

Flavio,
Take a look at this page if you haven't: http://mapserver.org/mapfile/join.html
Under 'Description', it mentions that you can't use joined data to 'affect the
look of a map'. I am pretty sure that this rules out your case.
David.

Hello Flavio,
As noted on the page you referred to, this JOIN only works for executed
queries...and I do not see a TEMPLATE in your layer. Are you aware that
this join only works for queries? (see the examples in that documentation)

Column names are case sensitive, have you checked this ?

Florencia,
As far as I know, Mapserver only works with vectorial data on PostGIS. So
having
a kind of BLOB (bytea)
column doesn't work.
I guess you will have to had those TIF files as a file to be able to load it
using a RASTER layer.

Florencia,
I have not tried to do this and I'm not sure it is even possible, but
you might have some luck using a GDAL connection to pull your postgres
raster data into mapserver. If you get this to work post a how to to
the list.
Thanks,

Flavio,
I think that if you have CONNECTIONTYPE OGR, the connection string
must have PG: (unlike the native mapserver Postgres connections?):
CONNECTIONTYPE ogr
CONNECTION PG:dbname='testdb' host=GSERVER1 port=5432 user='test'
password='test' sslmode=disable

Hi Carlos,
Thanks for your response.
Ok, but I want to show only one layer with some rasters (more than one). I
can save tif files into my system (directory into my hard disc instead of
PostGIS), but I am thinking about can show a layer with more than one tif
raster.
Any ideas?
Thanks a lot!
Hi Florencia,
You just can show a layer per LAYER section at a time. However, you can use the
GROUP label within each
LAYER section of each raster you want to show, to turn on/off all those layers.
Solo puedes mostrar una capa por cada sección LAYER a la vez. Sin embargo,
puedes hacer uso de

Thanks for your response again.
My problem is that the group of rasters not always the same (dinamic). For
example, rasters show according to the user logged (some users can see some
rasters but no all), everything depends on the user. With the other types of
layers (polygon,
If I remember correctly, you can use a PostGIS data set as a tileindex.
Perhaps it would be possible to have a PostGIS polygon layer that serves as the
tileindex with a where clause that only includes the footprint polygons for the
rasters that a particular user should be able to see.

David,
Exactly. I done this with a dynamic parameter, like this:
DATA the_geom from (SELECT l.* from lotes l, campos c WHERE c.id=l.idcampo
AND l.idcampo=%param%) as lotes using unique gid using SRID=-1
but I want to do that with raster layer. Perhaps another solution is in the
passage of
Any takers? I was just thinking, is there a native way using filters to clip
the returned data inside mapserver? I couldn't find any, but perhaps I was
not looking in the right place.

Hi,
Thanks all for your responses. Im a novice in Mapserver so, after reading,
now i know that:

map;
- I need to use a template always to show the
Hi,
Sorry, but i cant upload the shapes to postgres. The shapefiles are modified
using arcview and the data in the postgres is modified using a custom
desktop software that my client uses for about 5 years. The software open
the shapefiles, then using a ODBC connection with postgres, make the
Your client has some pretty custom requirements. How current does the data

hourly, or do changes to the data have to be immediately reflected in on the

Flavio,
I'm currently experimenting with joining a shapefile to a MS Access
file using OGR and ODBC (and stock mapserver v 5.2.1 from MS4W). Works ok:
CONNECTIONTYPE OGR
CONNECTION 'G:/GeoData/Parcels/Alberta/t_505033.shp'
DATA SELECT * FROM t_505033 LEFT JOIN
Hi John: The ids variable is used to perform a runtime substitution. It's not a
MapServer specific variable, just something I used in that particular example.
In the mapfile here's the county layer:
LAYER
NAME county
STATUS OFF
DATA data/bdry_counpy2_gen500
TYPE POLYGON
Colors are always RGB for the moment, and unfortunately OPACITY isn't bindable
at the moment. It would be a relatively easy
hack though (patches gladly accepted). Feel free to create a ticket and assign
it to me.

I'm not aware of any means to do this. If you're using PostGIS perhaps there's
a way to use the !BOX! hack in conjunction with some of the analytical
functions but it's a long shot... (see
