Without looking at the your details I remember one blog entry that might help.

Subject: [mapserver-users] polygon fill
hi all
iam trying to highlight the villages based on query
but only one polygon is highlighting
the query is based on the area of the villages, when user enters area
=** ,it is displaying 13 villages in the grid and also same time it
has to highlight the villages on the map
my code is
aspx page
protected void btnselect_Click(object sender, EventArgs e)
{
string query = ;
query = String.Format( select gid,box(geom),villname,geom,area(geom)
from villages where area(geom) + ddlsymb.SelectedValue ++ txtarea.Text
+ );
dt = MyClass.getData(query);
if (dt == null || dt.Rows.Count == 0)
{
Response.Write(No record found, Try Zoom in and click close to
feature.);
}
else
{
dr = dt.Rows[0];
//String selectedGID = dr[gid].ToString();
//gid = selectedGID;
var layername = villages;
for(int i=0;idt.Rows.Count;i++)
{
dr = dt.Rows[i];
String selectedGID = dr[gid].ToString();
gid = selectedGID;
Response.Write(String.Format(@scriptwindow.parent.highlightnav('{0}','{1}');/script,
gid, layername));
//Locate(query);
}
if (dt.Columns.Contains(gid))
{
dt.Columns.Remove(gid);
}
if (dt.Columns.Contains(geom))
{
dt.Columns.Remove(geom);
}
GridView1.DataSource = dt;
GridView1.DataBind();
}
}
js page
function highlightnav(gid,layername)
{
bPoint.params.gid = gid;
bPoint.params.tbl = layername;
//bPoint.params.getElementById = geom;
bPoint.redraw();
}
mapfile bpoint.map

Re: [mapserver-users] Is there a way to convert a QGIS layout into a .map file?
Hi, There is this plugin http://plugins.qgis.org/plugins/rt_mapserver_exporter/ and old documentation http://docs.qgis.org/1.8/en/docs/user_manual/plugins/plugins_mapserver_export.html Unfortunately the plugin makes mapfiles which were usable as-is with Mapserver 5.x but not since that. It also creates mapfiles which I do not like a lot because it is lazy with PROJECTION blocks etc. but that is at least partly matter of taste. But if you know how to write valid mapfiles for Mapserver v. 6.x and above then that plugin does make usable templates which can save time. It would be nice to get that plugin up-to-date. Other alternatives which do not help with QGIS styles but are worth having a look: http://scribeui.org/ and http://gisinternals.com/mapmanager.html -Jukka Rahkonen- Michael Kleih wrote: Hello all, I am using Mapserver since nearly 20 years and like it a lot.

Re: [mapserver-users] How use a spatialite as tileindex for raster
Hi, I use a batch file which creates own shapefile tileindex for each orthophoto directory because I need separate shapefiles for another purpose, snippet here: gdaltindex -t_srs epsg:3067 -write_absolute_path -src_srs_name src_srs %1.shp /%1/*.TIF and another batch file that combines them into Spatialite to be used with Mapserver: ogr2ogr -f SQLite -dsco spatialite=yes -dsco init_with_epsg=yes -a_srs epsg:3067 ortho.sqlite dir_0.shp -nln orthos ogr2ogr -update -append -a_srs epsg:3067 ortho.sqlite dir_1.shp -nln orthos ogr2ogr -update -append -a_srs epsg:3067 ortho.sqlite dir_2.shp -nln orthos ...

it works for file-datasources and there is a wrong definition for

But you should have to look at the mapfile in any case.
For finding and using the extension in qgis you have enable the
experimantal plugins.

The code for it lives on GitHub
(https://github.com/faunalia/rt_mapserver_exporter), so maybe some
passionate MapServer devs can contribute.

Re: [mapserver-users] Best integration with dynamic map information
Thank you so much, Mark! That's a very convenient/effiecient architecture for us since our engine is already in AWS. Thanks again for your help! Best regards, Ahmed On Tue, Mar 17, 2015 at 11:07 PM, Mark Korver mwkor...@gmail.com wrote: In order to serve a lot of requests you generally need to cache. That would be true of any query against a db, or against a shapefile. The point is, you don't want to go to db or to disk. In order make this happen for maps the usual pattern is to serve tiles. If your data gets updated every 5 minutes, and in your case it is the whole thing, not just some part. Then you need to make sure no map tile lives longer than 5 minutes, actually less than 5 minutes. One simple way to solve for this is to use a Content Delivery Network. something like this: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.html You would point the CDN at your TMS or WMTS server. which would never have to make the same tile more than once every few minutes. Another related point would be to put the tile server behind a load balancer, then point the CDN at the load balancer. on Amazon that would be an ELB. -Mark On Tue, Mar 17, 2015 at 1:41 PM, Lime, Steve D (MNIT) steve.l...@state.mn.us wrote: MapCache would be a **much** better option than using MapServer in tile mode. You still need something to render tiles (e.g. MapServer) but MapCache manages the tiles and is the interface between your client application and the tiled data. The brute force method would be replace the data and then blow away the cache and let MapCache (and MapServer) rebuild as users request tiles. The first request will result in MapCache making a call to MapServer to generate the tile/metatile, but subsequent requests for tiles will use the cached tiles. Others on the list may well have more experience and better ideas.

It's actually a new dataset copy every 5 minutes, it seems like replacing a shape file would be most efficient.

Seems like that should be a matter of resources and how much hardware you can throw at the problem. Are you using MapCache to serve tiles? MapServer itself is good for rendering tiles or more likely, metatiles. On thread safety MapServer itself isn’t doing any file locking. Presumably the OS or database is handling contention issues. I’d think the right way to go for data storage depends on your update process itself. If you want to incrementally tweak lines as new information becomes available then a database backend seems more reasonable – I’d think you could detect change easier and perhaps only retile very specific areas as a result. If instead you’re getting a new copy of your entire dataset every 5 minutes then perhaps a shapefile would work best – just replace the file and trigger retiling.

We would like to use Map Server to generate transparent tiles showing colored polylines of the traffic. I am newbie to Map Server, I got the server and workshop running and also I think I have some good understanding of the map file and layers concept. I have a question about integrating our traffic information as a data source to the MapServer. Important aspects for us: 1. Performance: since we are updating large areas every 5 minutes. We will need throughput like 10K images per second. Does this sound okay? 2. Threads safety: my concern what happens if while updating the source, the MapServer is actually rendering an image from old data. Any locks? I understand our options are: 1. Data files: such as shape files or KML files. 2. Database: PostGIS for example. 3. Service that pulls data: WMS server - I didn't dig much here.

Re: [mapserver-users] Is there a way to convert a QGIS layout into a .map file?
I wonder the same, especially seeing that plugin code living on GitHub. Think of how QGIS has become the frontend for GRASS, it could(should!) be the frontend for MapServer. There is definitely huge momentum in the QGIS community (I've even been asked to attend their first QGIS conference, and followup dev meeting, in May). I can imagine/dream of a joint MapServer/QGIS code sprint, totally funded (as a few of the OpenLayers3 sprints were) happening someday. Would be amazing. -jeff On 2015-03-18 2:50 PM, Lime, Steve D (MNIT) wrote: I've wondered if we could/should pull the plug-in into the MapServer project itself. -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Rahkonen Jukka (MML) Sent: Wednesday, March 18, 2015 3:16 AM To: Michael Kleih; mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] Is there a way to convert a QGIS layout into a .map file?
