Being on PostGIS I'd suggest using the native driver with something like that:
CONNECTIONTYPE postgis
DATA geom FROM (select id, name, now() as generated_date,
st_GeomFromText('POINT(-5 70)') AS geom FROM map WHERE id=%MYID%) AS tmp
USING SRID=-1 USING UNIQUE id
CLASS
LABEL
TEXT Species name: [name] (last updated: [generated_date])
FONT vera
TYPE TRUETYPE
SIZE 7
BUFFER 1
COLOR 0 0 0
FORCE TRUE
STYLE
GEOMTRANSFORM 'labelpoly'
COLOR 255 255 255
END
END
END
that works even better .. thanks!

But many elements of symbology encoding map to se:ParameterValueType which is a mixture of text nodes and ogc:expressions and this is generally not very well supported.

Re: [mapserver-users] WMS layer filtering
On 06/12/2013 14:23, Kralidis,Tom [Ontario] wrote:
Hi: we have a MapServer OWS instance which we use to disseminate
observations via WMS and WFS/SOS.
One of our layers has 1 million records (PostGIS backend). The layer
has CLASS level EXPRESSION objects for WMS visualization/classification.
We initially implemented a LAYER level FILTER, however we have use cases
to serve the same layer (with the same identifier) via WFS, in which
case we'd like all the data to be available.
Our problem happens when visualizing via WMS. We have a Boolean column
in our PostGIS table ('latest_observation') which allows us to filter
easily to visualize latest observations, which is our desired WMS
default.
Because we have defined CLASS level filters, the WMS GetMap request is
first querying and fetching all records and _then_ applying CLASS level
filters (which all include 'latest_observation=1'. So this ends up
hurting us performance wise.
We'd like to have this filter at the query level so that less members
are passed back from the SQL query.
When we do a LAYER.FILTER with latest_observation=1, the result is
instant (beautiful!). But if we put a LAYER.FILTER, this constrains the
data access from the WFS perspective against the same LAYER def.
Is there any way to apply a LAYER.FILTER type approach to work _just_ in
WMS mode? We'd like all the data in WFS mode.
I know we can duplicate the LAYER object as a workaround, but from a
data management perspective we'd rather now.
I hope I have explained this clearly enough. Any suggestions?
It may seems strange (?), but there is nothing in the WMS spec to filter
a WMS layer (that's why Geoserver has CQL filters), and I think the OGC
way to filter a WMS request is through an SLD stylesheet (which can be
generated dynamically).
Thanks
..Tom

I compiled mapserver with required libs (zlib, libgd, libjpeg, gdal(with python)). I followed some instructions from Begining Mapserver book and mapserver.org http://mapserver.org site. Now i want to install python mapscript and set up mapserver with apache2. Planing to create a django application and use python mapscript to interact with mapserver. The problem is that i dont find any explicite guide or tutorial how to do it right, this include setting working directory for mapserver and apache, setting permissions. Could anyone help me please.

[mapserver-users] some questions regarding getFeatureInfo, SLD, PostGIS
Hello,
I'm using Mapserver 6.0.1 with the following PostGIS layer:
http://pastie.org/private/84042k84vmljbontls5xvq
The user has the possibility to select quite a lot of filters, which
implies that the SQL query should, in theory ,be generated dynamically.
As this is not possible with Mapserver (run-time substitution with HTTP
parameters and VALIDATION ... END isn't powerful enough is my case), I'm
dynamically generating an SLD
(http://pastie.org/private/p66ml3uvqwcnphuuvera) to filter items and it
works very well.
Some questions:
- Why does Mapserver doesn't have a very lightweight template language
(or something similar) to dynamically build a string following given
parameters? It could be really useful to avoid unnecessary JOIN, etc.
For example something like:
http://pastie.org/private/bojm3pi1dwrv18m2tvq (this is just an example,
but the idea is there)
- I noticed in the PostgreSQL logs that sometimes Mapserver adds an
additional condition to the WHERE clause when SLD is used. For example
with the following ogc:Filter in my SLD:
#
ogc:Filter
ogc:PropertyIsEqualTo
ogc:PropertyNamebasis_of_record_id/ogc:PropertyName
ogc:Literal1/ogc:Literal
/ogc:PropertyIsEqualTo
/ogc:Filter
#
Mapserver adds an additional and (( (basis_of_record_id= 1) )):
(...) AS q where geom GeomFromText('POLYGON((-3.6860351557368
-9.81732918571448,-3.6860351557368 9.81732918571447,47.6860351496117
9.81732918571447,47.6860351496117 -9.81732918571448,-3.6860351557368
-9.81732918571448))',4326) and (( (basis_of_record_id= 1) ))
which is not bad as less rows have to be post-processed by the SLD engine.
However, as soon as I add an additional ogc:or (or ogc:and) as:
#
ogc:or
ogc:PropertyIsEqualTo
ogc:PropertyNamebasis_of_record_id/ogc:PropertyName
ogc:Literal1/ogc:Literal
/ogc:PropertyIsEqualTo
ogc:PropertyIsEqualTo
ogc:PropertyNamebasis_of_record_id/ogc:PropertyName
ogc:Literal2/ogc:Literal
/ogc:PropertyIsEqualTo
/ogc:or
#
Mapserver doesn't add this additional AND/OR clause (and ((
(basis_of_record_id= 1) OR (basis_of_record_id = 2) )) in this
case).. Why ?
- Is it normal that my SLD is totally ignored when I'm using
REQUEST=GetFeatureInfo? Is the SLD only processed with REQUEST=GetMap?
If this is the case, what's the typical alternative way of doing it?
Should I go through WFS .. ?
In advance, thank you for your answers :)
Julien

It is not powerful enough because it doesn't allow you to make simple
logical tests (if defined/equals/...), the run-time substitution is a
simple replace %FOO% by the value of FOO= from the query string.
It doesn't allow you to do something like: if FOO is defined or equal

What I've done is have the join in the sql but either join it to the

I typically use oracle syntax and not ansi syntax but the trick is to have
all the table joins in the sql but using case to alter the join condition.
I see.. the only problem I see with this solution is that you cannot do
inner join (as the resultset will always be empty if one of the join
condition is false).
Just curious: is the Oracle planner smart enough to not JOIN the table
if the join condition is false ?
With PostgreSQL it seems not the case..:
congo_river=# explain analyze select occ.id as occ_id, si.id as site_id

You can guess it from the coordinates, for example Origin = (-8563840.575678950175643,6466755.550653258338571) EPSG:4326 is naturally between -90,90 and -180,180. There does read AUTHORITY[EPSG,4326]] in one place of the gdalinfo report, but it is in the section that tells the datum or the projection. I am not sure what the right projection could be, but I found this projection wiht the same lookin parametrers from my Mapserver proj directory: # WGS 84 / Antarctic Polar Stereographic 3031 +proj=stere +lat_0=-90 +lat_ts=-71 +lon_0=0 +k=1 +x_0=0 +y_0=0 +ellps=WGS84 +datum=WGS84 +units=m +no_defs If this is correct, you do not need to reproject at all because your image is already in EPSG:3031. -Jukka Rahkonen- Thanks for the clarification, looks like I misunderstood the output of gdalinfo..!
