Re: [Geoserver-users] How can I requets multiple Geowebcache layer in single request?

[mano3688]

Thanks lot for information,
I was read the above you mentioned link,they are clearly mentioned   like
"The request only references a single layer"
So,Now I am using group layer option.
It is working.

Thanks David. I have installed opengeo community edition and thats 
working. However, I might create another server and see how this works.

Please ensure that you are running the JVM in headless mode (so that it
won't attempt to connect to a display.)  The simplest way to do this is to
add '-Djava.awt.headless=true' to your java command-line arguments.  For

Re: [Geoserver-users] Rasters, Tiles, and FME

[Jonathan Moules]

Hey Simone,

Thanks for your thorough reply. Useful!

- Resampling:
I've done some experimenting with Resampling since my email and, at least
for the data I was testing, Nearest Neighbour came out best (though
obviously entirely subjective). This was for a regular RGB map (Ordnance
Survey MiniScale specifically). There was also a significant difference in
file sizes, with Nearest Neighbour being the smallest, and Cubic being the
largest (double!). I didn't expect such a significant difference, may be
worth noting somewhere.

- External Overviews:
Thanks, but I'd found out how to create them with GDAL. My issue is - how
do I get GeoServer to use them? Does it just pick them up automatically or
do I need some sort of particular directory structure?
GDAL seems to create a single, absurdly huge file, so I guess it doesn't
compress the external overviews. Based on what I'm seeing, I'm not sure if
FME can create them; I expected multiple separate files (one for each
layer), but the "external overviews" are basically identical to internal
overviews but minus the source data.

-Overviews:
How do you determine how many levels to create? I remember this page from
years ago when last I used GeoServer:
http://docs.geoserver.org/stable/en/user/tutorials/imagemosaic-jdbc/imagemosaic-jdbc_tutorial.html#how-many-pyramids-are-needed-
does this carry over to GeoTIFF's overviews?
I may be reading this wrong, but the example in the PDF has 7 layers but
only really needs about 3 as after that they're smaller than the 1:1 tiles.

Is there any point in creating pyramids with a value of 1 (as in, 1 2 4
8...) ? GDAL lets you do this but if I'm understanding this correctly,
they're entirely superfluous (I mention it because Russ's example he
generously posted starts at 1).


Tile size:
Might there be a formula for calculating optimal size?
For example, if I have a 94488*157480 pixel GeoTIFF (my largest - about
2.5GB compressed), if I divide them by 512 I get
184*307 tiles = 56,488 tiles

For 256 I get:
368*614 tiles = 225,952 tiles

So if there is/was a formula, it might be easier to figure out what size to
go with, or at what point you'd want to be scaling up to ImageMosaic.
Based on disk seeks etc, and some experimentation, I'd guess that a number
could be contrived allowing the documentation to say:
"If you end up with > X,000 tiles, go with ImageMosiac" and "Aim for
between X,000 and X0,000 tiles in a GeoTIFF"
Just a thought, would be helpful for optimisation.

Documentation:
I was considering contributing to it for this but at this point certainly
don't know enough (you may have noticed from my above questions ;-) ).
I would however suggest that this section of the help:
http://docs.geoserver.org/stable/en/user/production/data.html?highlight=gdaladdo#pick-the-best-performing-coverage-formats-
It would gain from the info on pages 7-9 of your PDF.

Cheers!
Jonathan

Re: [Geoserver-users] simple GeoWebCache question (formats)

[Arne Kepp]

GWC is used, but the tiles that you seeded are not.

If you request a tile that does not exist in the cache, GWC will ask 
GeoServer to render it and then store the result (a PNG, in your case) 
in case someone else requests the same tile again.

In most cases this type of caching (on the fly, as needed) is the best 
option anyway. Seeding is only important when updating tiles or when WMS 
can't keep up with realistic traffic loads.


The JPEG tiles you seeded are just wasting space. Once you save an image 
as JPEG the alphachannel (transparency) is lost, so they cannot be used 
to make PNGs.


(It's also possible to mix JPEGs and PNGs to get both transparency where 
needed and good compression, but nobody funded the proposals to 
implement such a feature.)

So if I seed as JPEG but always request PNG, does it just not use the 
GeoWebCache in that case (or does it convert the cached tiles to PNG on 
the fly)?

No worries, actually this feedback gives me some hints on how to
update the presentation :)

That said, the considerations done for MapServer applies more or less
to GeoServer as they are more related
to how to geotiff works rather than to how MapServer or GeoServer works.

Anyway, my suggestions are as follows:
- tile size-
256 or for very large bigtiff 512 is my preferred size.

Using a tile size that is too small may result in too many seeks
operations on a side and on the other side might result into a TIFF
directory explosion.
The more tiles we have the more info we need to encode in the TIFF
Directory, which is essentially a list of offset locations that tells
us where the data is on disk.
For bigtiff where we have thousands of tiles it can be MB big.

- Resampling -
This depends on the data.
For RGB like data (orthos and the like) I would gor for higher order
interpolation to reduce aliasing (cripsy images).
For data like DEM or other data that contains real values to which you
will want to apply a color map I would for for Nearest neighbor to NOT
introduce artificial values.
In some case you might want to use bilinear of average but this
depends much on what you want to do.

- Overviews -
I usually use steps of 2, as many of them as possible although I
usually don't create overviews smaller than the tile size

- External Overviews -
This works only with pure geotiff (or bigtiff as well as the plugin is
the same). ImageMosaic does not (yet) support that.
External overviews are useful just in case you don't want to touch the
original files or in case they do not support inner overviews (which
is not the case for geotiff).

Creating external overviews can be done with gdaladdo, check this link
http://www.gdal.org/gdaladdo.html

Let me know if this helps. I will try to update those slides as well
as to create some additional docs.

You might even want to contribute some doc once you get to where you
needed to go :)

Re: [Geoserver-users] Rasters, Tiles, and FME

[Simone Giannecchini]

Ciao Jonathan,
I don't know about FME therefore I cannot comment on how to do such
things with it. I hardly believe many people on this list (as well as
on other OS oriented lists) will know it much.
This to say that most intructions you'll find will be oriented towards
OS tools like GDAL utilities rather than towards proprietary solutions
like FME.

That said, the suggestions you are looking for are inside the document
andrea suggested (here the link again http://goo.gl/TXJRS):

- slides 7-9 when do use what
- slides 10-13 how to optimize each single geotiff
- slides 17-19 how to prepare a mosaic

and so on.

If you check on the web you'll also find other docs that compare tile
sizes rather than types of compression, e.g.
http://www.fosslc.org/drupal/content/tuning-gdal-raster-performance

 Hi Jukka,

 Relating to the TIFF's, I'd still prefer to use one single tool
 (specifically FME) for tile/image creation. FME can create pyramids, but 
 not
 as part of a GeoTIFF. So I can create separate TIFF files and tile them if
 necessary too (either internal tiling or regular tiling), but how do I get
 these into GeoServer?

 Is there a resource out there which describes the different Raster
 serving extensions and the advantages/disadvantages of each?

I'm using Geoserver master branch, and yes it is an app-schema type.
My schema uri is
http://inspire.ec.europa.eu/schemas/au/3.0/AdministrativeUnits.xsd(urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0).

Why would you want any sort of WFS import in a WFS DescribeFeatureType

I don't really want to have this import, but it is there i haven't
customized any thing to get this i guess.
Maybe i could try to remove it but i don't know how to process.

thanks for help

Re: [Geoserver-users] Rasters, Tiles, and FME

[Russell Hore]

This might not be exactly what you want but my workflow (Under Linux) is

1) Take the raw TIF images
2) Add a .PRJ file for each image
3) Add the World file for each
4) Run gdal_translate for each file
for file in `ls *tif`
do
gdal_translate -of GTiff -co "TILED=YES" -co "COMPRESS=DEFLATE" -co 
"BLOCKXSIZE=512" -co "BLOCKYSIZE=512" -a_srs "EPSG:27700" $file out/$file
done
5) Ran a gdaladdo for each file in 'out'
for file in `ls *tif`
do
gdaladdo -r average $file 1 2 4 8 16 32 64 128
done

6) Added them to Geoserver (2.2 RC1) using ImageMosaic
