Re: [mapserver-users] geotiff 48bit with mapserver 7 wms

2017-04-14 Thread Stephen Woodbridge

Yeah, technically a geotiff can be any format, but mapserver only 
supports a limit set for band widths.


A new version of Mapcache was just released and it has GDAL support in 
it  and serves WMS, but I'm not sure if it will do what you want.


Sorry, I'm out of ideas on this.

I tried all tiff IMAGEMODE for my data set. None gave me 16 bit at the

As far as I understand gtiff is 8 bit.
The only IMAGEMODE for integer is signed INT16 , which is unfortunately 
the only supported integer data type. For RGB data unsigned integer is 
the only integer data type that makes sense. Just if i change the 
IMAGEMODE to FLOAT32 mapserver will serve more than 8 bit per band.
I think i will give gdal and float32 bit a try nevertheless it will 
double the image size.

Maybe someone else has an idea.

You can define multiple output formats in the mapfile, and let the
browser use the 8bit png and have qgis request images in gtiff format.

Hi Steve,

thank you very much for your help. The Mapserver is serving the tiles

I need the 16bit because i want to use the wms as a base layer for some
further processing with qgis or another gis client. So no problem
regarding browsers for me.

I will take a look and change the data type to float32 for the tiff

Any suggestions on this matter are highly appreciated.

Hi there,

iam having some trouble to serve 48 bit geotiff images with a mapserver
7 wms. I created to layers for speed purposes with scale limiters. The
lowres layer is served well and looks good, it is 24bit geotiff
data(8bit per channel). But if the layer changes to the highres, 48bit
geotiff data(16bit per channel), the data is shown wrong.
I searched for some hints regarding a similar issue but could not find
something.

This is a screenshot of the loaded highres layer. It does not matter if
i load a bbox inside the browser, qgis or another wms client. The
highres data looks always the same.

Hello, Jeff.

You were spot on! I had the lat/long's reversed as I was using 4326. 
Also, I looked at the warning and fixed those to.


Thanks so much for you help and service on this message board. Folks

Re: [mapserver-users] styling point shapefile for wms

2017-04-14 Thread Jeff McKenna


Hi Derek,

Since your request is using WMS 1.3.0, the issue could be specifying 
long/lat vs lat/long in your CRS parameter of the WMS GetMap request 
(see example requests at 
http://mapserver.org/ogc/wms_server.html#coordinate-systems-and-axis-orientation).


I would also check the GetCapabilities response for any warnings.

Also, another option for testing your mapfile styling instead of your 
first link (CGI method) is to use the shp2img commandline utlity, that 
comes ready for your use in MS4W as well (see 
http://mapserver.org/utilities/shp2img.html).


Happy mapserving :)

2017-04-14 Thread Jeff McKenna

I can imagine after you do a GetCapabilities request you will notice 
many warnings in that response: be sure to get rid of all warnings, or 
else there will be problems in clients downstream (QGIS etc).  For 
example, be sure to add metadata for all layers, and a projection object 
to all layers, etc etc.  Best/easiest to just follow a working example 
mapfile:  http://mapserver.org/ogc/wms_server.html#sample-wms-server-mapfile
