[postgis-users] postgis & mapserver

[Obe, Regina DND\MIS]

I think you can pass point parameters to the mapserver CGI (which I have not
tried in a while) or alternatively you may want to try using Mapscript to
set the extent etc.

The way I've done something similar is to use php mapscript

I query the points from the database and then do something like

$map = ms_newMapObj($map_path."\\comnotif.map");
$map->setextent($rs->fields("minx"), $rs->fields("miny"),
$rs->fields("maxx"), $rs->fields("maxy"));

where $rs refers to storage of my data from postgis.

I will ask this on the mapserver list as well.

Let's say I have the Census street level and other features data
in PostGIS.  I also have two lat/lon pairs.  Is it possibly to have
PostGIS/MapServer do the following, dynamically:

1) show the street level data with labeling of the street names
2) pinpoint the two lat/lon locations
3) automatically set the extent to include both lat/lon locations within
about 80% of the frame

it seems that I have to have a static .MAP file the last time I played
with MapServer, which defeats the purpose.  Any pointers?

Thanks!

Tim
