geotiff 48bit with mapserver 7 wms

David-8
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.

image loaded from highres layer:

the gdalinfo for one 16bit 3-band tile:

Best Regards,
David

Read this:

You need to add to your highres layer

PROCESSING "SCALE=AUTO"

Or per band scaling. I done thing most browsers know what to do with 16
bits per channel.

In reply to this post by David-8
Hi Steve,

thank you very much for your help. The Mapserver is serving the tiles
with the correct RGB values now. The problem is, that it is serving 8
bit per band and not 16 bit.
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
files. At least this is an supported OUTPUTFORMAT for mapserver.
Any suggestions on this matter are highly appreciated.

Cheers,
David

Re: geotiff 48bit with mapserver 7 wms

http://mapserver.org/mapfile/outputformat.html

Why not serve them a GTiff format for qgis?

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.

Re: geotiff 48bit with mapserver 7 wms

David-8
I did not reply after my latest test, sorry.
I tried all tiff IMAGEMODE for my data set. None gave me 16 bit at the gis
client.
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.

Re: geotiff 48bit with mapserver 7 wms

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.

Re: geotiff 48bit with mapserver 7 wms

ruhri
Hi,

maybe it would the better way to use the WCS-Interface? To be honest, I didn't use it that way by myself. But it sounds like that would be an proper scenario for WCS (doing some "more" with that data besides the classic "viewing").

To configure WCS shouldn't be that hard, I think:
http://mapserver.org/ogc/wcs_format.html
http://mapserver.org/de/ogc/wcs_server.html

Moreover QGIS has built-in WCS-support.

Just an idea...

Regards Ben

Re: geotiff 48bit with mapserver 7 wms

David-8
Hi Ben,

Thank you for your input.
I did set up a WCS yesterday and found the same issues.
I will change the data type to FLOAT32 and give it a try.

Cheers David

Re: geotiff 48bit with mapserver 7 wms

Berger, Cora
In reply to this post by David-8
Dear David, Steve, Ben, etc.
I am working with MapServer-WCS. I still have problems defining the correct output formats. Input to most of our WCS are 8bit Geotiffs. The MapServer WCS-output is either tiff, png or jpeg with 24bit or Png;mode=8bit with 8 bit (if no output format is defined). The png;mode=8bit-format changes the imagecolours, so it isn't really useful. I can't get a colored 8bit Geotiff as output (a 8bit-definition always results in greyscale images). I tried different output format-definitions, none of them worked. I can define a palette for the png-format, but unfortunately not for any other format.
For our WCS it is important that the output-data looks the same like the input-data. It seems that at the moment MapServer can't just pass the input-data through... This might be a GDAL issue...

So if you find a way to define your wished output-format, please share it, maybe it helps me, too. Maybe anybody else has an idea?

Cora

Re: geotiff 48bit with mapserver 7 wms

David-8
Hi Cora,

do you use PROCESSING "SCALE=AUTO" with you LAYER definition?

SCALE[_n]=AUTO or min,max
This directive instructs the GDAL reader to pre-scale the incoming
raster data. It is primarily used to scale 16bit or floating point data
to the range 0-255, but can also be used to constrast stretch 8bit data.

http://mapserver.org/input/raster.html#special-processing-directives

Cheers David

Re: geotiff 48bit with mapserver 7 wms

David-8
So, i did some testing.

The wms is not serving the images with float32 as data type. It shows
the same issue, false colors.
The wcs is working and serving the float32 data type data.
For my use-case setting the MAXSIZE higher than the tile dimension was
important.

Well QGIS does show just a black image, but GlobalMapper is loading the
data.

Just out of curiosity, can somebody explain "WCS_SIZE" "..." to me? Is
this the size in pixel x y for the complete TILE_INDEX?

David

Re: geotiff 48bit with mapserver 7 wms

Hi David, Hi list,

@David: you said "Well QGIS does show just a black image"

I assume that this is just a layer-specific contrast setting. Maybe just play around with stretching (layer properties -> style -> band rendering), e.g. set "min" to "0" and "max" to "255" (per each band) and then set "contrast enhancement" to "stretch to minmax"

Regards Ben

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

So, i did some testing.

The wms is not serving the images with float32 as data type. It shows the same issue, false colors.
The wcs is working and serving the float32 data type data.
For my use-case setting the MAXSIZE higher than the tile dimension was important.

Well QGIS does show just a black image, but GlobalMapper is loading the data.

Just out of curiosity, can somebody explain "WCS_SIZE" "..." to me? Is this the size in pixel x y for the complete TILE_INDEX?

David

Re: geotiff 48bit with mapserver 7 wms

Berger, Cora
In reply to this post by David-8
Hi David,
Thanks for your help. I tried PROCESSING "SCALE=AUTO". This method results in a red/white image. All the labels in the map are drawn red (originally black). The whole topographic information in the background is just white (originally many different colors). I tried it with a combination of different outputformat-declarations and processings. Unfortunately I didn't get a correct result.

Cheers Cora

Hi Cora,

Could you prepare a small sample image and put it somewhere for downloading? Or did you already do it in some earlier mail?

In reply to this post by ruhri
Hi Benjamin,

thank you for your tip. QGIS renders the tiles if a set min/max and
"stretch to min/max".
I did the test with a smaller data set (200 tiles 130MB each).

My problem now is, with all tiles (~18500) the connection times out,
even with small bounding boxes like:

http://192.168.3.231/?MAP=/maps/MAP/eowcs2.map&&SERVICE=WCS&VERSION=1.0.0&REQUEST=GetCoverage&FORMAT=GEOTIFF&COVERAGE=test&BBOX=646021,5524001,648018,5525998&CRS=EPSG:32718&RESPONSE_CRS=EPSG:32718&WIDTH=4000&HEIGHT=4000

(QGIS always uses the full extent as bbox for the query and times out.
Even zoomed in. *sick*)

The same data set as WMS, with MINSCALEDENOM MAXSCALEDENOM runs very
smooth.

I did not find very much help regarding performance improvements and
mapserver. For WMS you find alot.

Cheers,
David
