Re: [mapserver-users] WMS TIME parameter slow
Hello,
i have setup a test db with a 'timestamp' date field (-MM-DD HH:MM:SS).
Tests have been done with various request patterns i.e. leaving out the
HH:MM:SS part etc.
This works just fine and you allways get fast INDEXED SCANS on this. Requests
with an interval to seconds is possible and fast, even within millions of data
sets.
So to me it looks like that you don't need 'date_trunc' at all. But as said
i'am not a db/sql guru.
Just two observations:
1) Postgres default is to cast the request to '::timestamp without time zone'
in Version 5.3:
i.e.
Index Scan using bro_v32_timed_y2003_datum on bro_v32_timed_y2003 bro_v32_timed
(cost=0.00..8.28 rows=1 width=8) (actual time=0.012..0.012 rows=0 loops=1)
Index Cond: ((datum '2007-12-10 10:00:00'::timestamp without
time zone) AND (datum '2007-12-10 13:00:15'::timestamp without time zone))
So it might be an idea to cast the request explicitly and not to rely on
POSTGRES defaults (or let the user specify a time zone).
I have done no tests with time zones set.
2) The HH:MM:SS part if present (it can be left out) needs to be regexped
because POSTGRES won't accept 'HH' or 'HH:' only. A minimum of HH:M is required.
Just my 2ct. I have patched MS 5.6.1 with the above for our setup and it works
just fine.
Thanks for working this over in MS6.

Heiko
Sorry to jump late on this.
The use of the date_trunc function for postgis layers (described
http://mapserver.org/ogc/wms_time.html) was from what I remember to
allow queries (on a timestamp field)
like time=2001-01-01 expecting to get back all values of the day
regardless of the time set. I have entered a bug on it
(http://trac.osgeo.org/mapserver/ticket/3382) to be able to review it
before the 6.0 release.

Paul,
thanks for staying at it. These timings i get with the variation of the
theme. The second best is to cast 'datum::timestamp'. But still beeing
32times slower than just a trivial compare on the index as in 1). The
slowest run is the brute force 'date_trunc' without cast 3). So to me this
is a bit voodo why postgres refuses to scan the indices in proper speed in
2) and 3).
The maximum index scan i get with 'date_trunc' is a 'Bitmap Heap Scan' on
the index with scenario 2).
Of what i have found inside the docs/google is that even when casting
'datum' inside postgres the request, here generated by MS, should or have
to be casted as well which is not (at least by now).

Re: [mapserver-users] WFS limit time interval to POSTGIS
Hi there,
There is no explicit support of a TIME parameter in wfs but I believe
It should be possible on a postgis layer to use the FilterEncoding to
limit the request: would something like this work for you:
Filter=FilterAndPropertyIsGreaterThanPropertyNameyour_time_field/PropertyNameLiteral2007-01-02/Literal/PropertyIsGreaterThanPropertyIsLessThanPropertyNameyour_time_field/PropertyNameLiteral2007-01-03/Literal/PropertyIsLessThan/And/Filter
regards,
Thanks very much for the suggestion. It does not work that easy (of course ;-)
) but you can filter using the following converting the date to UNIX epochs
first and compare the integers.
Unfortunatly the WFS part of MS 5.6.1 does not handle the type 'date'
-MM-DD for comparison or calculus.
This works:
http://localhost/cgi-bin/mapserv.patched/?map=/var/www/localhost/mapserver/wfs6_include.mapSERVICE=WFSVERSION=1.0.0REQUEST=getfeatureTYPENAME=BRO_V32_TIMEDFILTER=FilterAndPropertyIsGreaterThanPropertyNamedate_part('epoch',datum::timestamp
without time
zone)/PropertyNameLiteral1191359000/Literal/PropertyIsGreaterThanPropertyIsLessThanPropertyNamedate_part('epoch',datum::timestamp
without time
zone)/PropertyNameLiteral1191359640/Literal/PropertyIsLessThan/And/Filter
Still quite ugly to mee.
Is there a deeper reason for not having a time spec within WFS ?
To me you usually have data points in space _and_ time. But i'am not a GEO man
either (daily satellite based measurements we have).
Thanks and Regards

Re: [mapserver-users] Multiples shapefiles, one LAYER
Conociendo más a fondo tu situación, pudiera ser que exista una alternativa si en vez de archivos SHP hicieras uso de bases de datos relacionales como PostgreSQL, MySQL u Oracle. Mi idea consiste en que cada propietario integrara su información en una base de datos, en donde podrían actualizar cuando quisieran. Tú por tu parte, creas una vista en la que unes (JOIN) las diferentes tablas de cada propietario, si y solo si la representación geometrica es la misma. Ya solo generas un archivo MAP con una sola capa haciendo referencia a la vista. Yo en lo personal trabajo con PostgreSQL+PostGIS y ha resultado una excelente opción.

Alexandre, you are right, if the expression is an regular expression, it shouldn't be quoted.

Can anyone tell me if there is a WMS server out there (that's working)
that serves Open Street Maps data? I've searched and found some old sites
that don't seem to be working now, and I found some information that talks
about a MapServer solution that involves downloading several helper files
and running things through PostGIS, but is it that complicated? Isn't there
just a simple WMS server out there I could use to load US streets into a
MapServer map or is this not the best way to go about it?
I also tried http://services.giub.uni-bonn.de/wms?, with no luck. I
couldn't even get capabilities from it.
Here's one of the ones I tried. I'll post the code so if anyone sees a
problem with it, please let me know? That would be helpful. But as it is,
this server also doesn't appear to be working. Both of these were mentioned
in search googlits, but there's not a heck of a lot out there about this.
