[MapServer-users] Questions about using c#/mapscript

[Atlanta Geek]

I've been using mapserver for a couple of years.
I'd like to generate maps and embed them in emails without running the CGI
service. The maps will be decorated with some linestrings.

Is C# Mapscript the right approach for this? Does mapserver work with .NET
6?

Re: [MapServer-users] Layer is opaque

[Atlanta Geek]

Thank, that gave me the hint I needed.  jpegs were being requested and not
pngs.  It turned out  the leaflet app I was using defaulted to jpegs even
though I told leaflet the layer was transparent.  I forced png and it
worked.

So I would put the INCLUDE in all the layers, correct?

[mapserver-users] Same database connection across multiple layers

[Atlanta Geek]

Is there a way to set the db connection only once for multiple layers.
We have a very dynamic mapfile with lots of layers and its a pain to
replace the db name when doing development or changing for a customer.  We
are running ms4w as well.


In addition to this is it possible to set the connection string outside the
mapfile.  Maybe as an option to the cgi script or something.

Im attempting to configure mapcache.
I assume that this is covered in this mailing list as well.  Mapcache is
returning images of the map for me but the cache files are not being
written.  Its strange because I can use the seeding command with the same
xml file and its populating the expected directory but when I go through
the mapcache script its not writing to that cache directory.

Any guidance would be appreciated.

The URL Im testing with is this.
http://192.168.112.225/mapcache?service=WMS=GetMap=default==image%2Fpng=true=1.1.1=2048=2048=EPSG%3A3857=-10018754.171394622,0,0,10018754.171394628



mapcache.xml is as follows:

   
   /tmp/mapcache
  
   

   fast
   256

   
  
 
image/jpeg
default
/usr/lib/cgi-bin/osm-bw.map

When using mapcache to my mapserver I am getting the following error.Access
to

* XMLHttpRequest at
'http://192.168.112.225/mapcache/?SERVICE=WMS=GetCapabilities
'
from origin 'http://192.168.115.38 ' has been
blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains
multiple values '*, *', but only one is allowed.*

I think this is caused by the fact that I have a forwarding rule in my
mapcache.xml




*  
http://192.168.112.225/cgi-bin/mapserv?version=1.1.1=/usr/lib/cgi-bin/osm-bw.map

  *
*  *

and in my apache.conf I have this





*Header add Access-Control-Allow-Origin "*"
Options FollowSymLinksAllowOverride NoneRequire all denied*
*--*

So one of the Access-Control-Allow-Origin  comes from the apache server for
the GetCapabilities call and then another is added because the
forwarding_rule adds the header as well.

What is a good way to get around this.  I tried to just add the
access-Control-Allow-Origin rule on the mapcache path but it did not work.

Re: [mapserver-users] QGIS WMS SINGLE CONNECTION: MapServer Multiple Maps Request

[Atlanta Geek]

You can put both layers in the same group and then use their group name
instead of layer name.

Re: [mapserver-users] Data Stores for mapserver.

ElasticSearch is one of our options.  Are these available in mapserver.
Though we've been using mapserver for a year now its mostly been crafting
the postgis queries and not much else

[mapserver-users] Data Stores for mapserver.

[Atlanta Geek]

How difficult is it to add a new datastore to mapserver.  We currently use
postgres but with a bigger need for deeper data analysis we are looking at
other datastores for our report engine. Mapserver is one component of this
engine.  Does anyone have any experience using any other datastore with
mapserver that is analytics specific?

Re: [mapserver-users] Show traffic on roads.

[Atlanta Geek]

The display traffic was an example and I was thinking it was just a GUI
thing.  What I am actually modelling is cable laid in the ground.  And what
I want to show is a heatmap representing the likelihood of there being an
issue at this point on the fiber.
The data will be stored as an array of numbers which each cell corresponds
to a distance along a route.  This array could be thousands of values.The
heatmap will be in the shape of the lines. So I did not want to have as
many line segments as I do cells in the array just to represent one cable.
