Re: [mapserver-users] serving WMS GetFeatureInfo to ESRI JavaScript client

[Richard Greenwood]

Hey Steve,

Thanks for the reply. I flailed with this for quite a while. I'm not an
Esri user and the vendor that I'm supposed to support is unfamiliar with
WMS. I was trying to follow an Esri example that was returning XML for
GetFeatureInfo requests but I was making a lot of (bad) guesses. In the end
I built a very basic app with the Esri JavaScript client that displayed
GetFeatureInfo responses in a popup. So I've proven that it can be done
which allows me to throw the ball into the vendor's court.

To sort of answer my own question, plain unformatted text with a text/html
mime type displays in the Esri JavaScript client (jsapi) attribute popup.
XML does not appear to be necessary or helpful.

Thanks,
Rich

Hi Rich! I didn't see any replies to this email and I don't have any
particular experience. That said, it seems to me that the vendor that is
receiving the content would want it in some sort of presentation agnostic
format so that they can apply a design, choose which attributes to display
and so forth. So HTML doesn't make that much sense and standard XML/GML
responses would be better IMHO.

Re: [mapserver-users] Asking help

Hi,

as mapserver tells you: unable to access file

make very sure that the files exists and the path is correct. If so,
have a look at the access rights, the user www-data must be allowed to
read the mapfile.

By the way it is not a good idea to store the mapfile in the apache home
because it is now accessible via http:/servername/routing.map ->
everyone can read it an find critical information as file-paths and
database connection information ect..

Jörg

And another one: it would be nice, if you could use a more speaking
subject, so it easier to find your questions and answers in the
list-archive.

[mapserver-users] Handling of NoData in WCS with MapServer

[CASTRO, Emmanuel via MapServer-users]

Hello

I have another question about MapServer capabilities. In my technical tests, I 
am trying to serve a GeoTiff Float32 with a declared NoData value (i.e. 
-3.4028234663852886e+38).
The GeoTiff file resulting from my WCS request transforms the NoData value to 
0, which is problematic because 0 can be a real data.

Is there a way to handle this problem?

I think I can prepare the GeoTiff file by filling the NoData with a value that 
I control, and then declaring it in the WCS nilValues metadata ; however I 
would like to avoid preprocessing my input files with gdal_translate or 
gdal_fillnodata.

Thanks

Emmanuel

Re: [mapserver-users] MapServer 7.4.3 - Poor projection from British National Grid (EPSG 27700) to WebMercator (EPSG 3857)

[BenH]

I have tried some tests of this.
A simple view, outputting the geometry with ST_Transform, is not
performant at all - the transform breaks the spatial index and it's a
large dataset.
I assume that would still be an issue with a materialized view.
So I think the only PostGIS option would be to create a full copy of the
geometry with its own index. I've tested this, so it is a fall back
option - but it's a lot of data duplication and the Mapserver transform
is really quick.
Thanks
