RE: [mapserver-users] plotting points dynamically
Suman I am doing this another way Although I am using GeoMoose/MapServer... I am using an OGR connection in my map file to connect to a MySQL database via a OVF filethis is plotting Points based on XY Coordinates, which is querying the database. I am would have to look up again what I am doing if you are interested in this. Is this something like you are doing Bobb. I am not familiar with the Query/Render engine in map server.

RE: [mapserver-users] plotting points dynamically
I generally do this all via MapScript, I'm using PHP. I add some basic
layers with the styling that I want to my mapfile. Then using MapScript
I make a copy or modify the mapfile layers. I even do this with Oracle
Spatial layers. Here is a sample of my code:
$layer_data = "geom FROM (";
$layer_data .= " SELECT st.bts_nbr,";
$layer_data .= " sgt.geom";
$layer_data .= " FROM site_tab st, site_geom_tab sgt";
$layer_data .= " WHERE st.site_id =".$_GET['site_id'];
$layer_data .= " AND st.site_id = sgt.site_id";
$layer_data .= " ) USING SRID 8307";
//plot site
if (!$oMap->getLayerByName("Selected Sites")) {
$point_layer = $oMap->getLayerByName("Point");
$site_layer = ms_newLayerObj($oMap,
$point_layer);
$site_layer->set("name", "Selected Sites");
$start = $point_layer->index;
$end = $site_layer->index;
for ($x=$start;$x<=$end;$x++) {
$oMap->moveLayerUp($site_layer->index);
}
} else {
$site_layer = $oMap->getLayerByName("Selected
Sites");
}
$site_layer->setConnectionType(MS_ORACLESPATIAL);
$site_layer->set("connection",$spatialconn);
$site_layer->set("data", $layer_data);
$site_layer->set("status",MS_ON);
This let's me do a lot dynamically.

Subject: [mapserver-users] plotting points dynamically
Hi all,
I am working on a project which requires adding points to a basic map
dynamically. That means the basic map will be read from the map file.
Then the points will be queried from a database preferably PostGreSQL
and then plotted on the map. I cannot add the query to the map file
because the points will be generated dynamically at regular intervals.
Is there any way I can do this in mapserver?

RE: [mapserver-users] plotting points dynamically
Hi bobb, Thanks a lot. You got my point. I will be adding the points to the postGIS database with the help of C#. Regarding mapserver connectivity to the database - how can I connect to it without writing in the mapfile? Again can you give me some reference as to how it can be read as a display request by mapserver?
