Re: [Geoserver-users] Vector-tiles: zoom-dependent generalisation

2017-02-02 Thread Dave Blasby 
Hi,

Mapbox vector format is in integer-ized pixel coordinates, so doing more
than that wouldn't affect the output.

For the other formats (i.e. geojson), you can use the overSamplingFactor so
it gets better resolution.

If you need to change these, you're probably requesting tiles at the wrong
resolution for what you're drawing.

Thanks,
Dave

[Geoserver-users] Vector-tiles: zoom-dependent generalisation

2017-02-02 Thread Edward Mac Gillavry 
Hi all,

Although 'Support on the fly geometry simplification' has been turned 
off on the Store, there's still some kind of zoom-dependent 
generalisation going on for vector tiles. Can the amount of 
generalisation be adjusted for each zoom level? Is it the 
overSamplingFactor? Can this be adjusted somehow as well?

Thanks in advance for your suggestions!

Cheers,

Edward

Re: [Geoserver-users] Gdal crash geoserver/tomcat7 on ubuntu server

2017-02-02 Thread Michele Aurelio 
I have the same problemi with GDAL libraries installed on CentOS 7 (TOMCAT
8).
when i try to set up a store, the geoserver (version 2.10.1) crashes and
restart.

the server reports an error in the java-1.8.0-openjdk

is there anyone who can help me to understand the problem?
Thank you

Michele

Re: [Geoserver-users] Cannot get InputTransparentColor to work in ImageMosaic

2017-02-02 Thread Jason Newmoyer 
I checked my settings and I am using Nearest Neighbor in all cases.

I've also tried tried to generate an alpha band with "gdalwarp -srcnodata 0
-dstalpha" but it will not allow me to use YCBCR photometric option because
apparently it requires it to be exactly 3 output bands. Anyone know how to
work around this?

Both.  For WMS, there's just one setting for the whole geoserver, but if you're 
using WCS, there's a per-layer setting for interpolation.

Do you mean in GeoServer layer settings or when processing with GDAL?

I'm not sure if this is the same issue, but we encountered "bleeding" of near 
black pixels with geotiff's with JPEG compression. We have subsequently 
switched to a lossless compression in our source geotiffs and it works pretty 
well.

Yes, when I do that it turns the black areas transparent in the resulting 
image, as expected. However, the tiles still overlap each other instead of 
showing through.

Here's a piece of the image. The area marked red I would expect to be imagery 
showing through from the tile underneath when using InputTransparentColor.

GeoServer 2.10, RHEL 6

I cannot seem to get the InputTransparentColor configuration to work as 
expected with my ImageMosaic layer. I have a mosaic of satellite imagery 
(standard RGB, YCbCr JPEG compressed with overviews) tiled into a regular grid 
of square tiles. Tile index is stored in PostGIS using a view. Tiles are 
ordered (zindex column) so newest imagery ends up on top.

When two tiles overlap, the evil black nodata fringe of the top most layer 
shows over top of the next tile underneath. I believe InputTransaparentColor is 
intended to fix this. However setting it to 00 actually results in a FULLY 
transparent image. Not an exception response, an actual transparent png.

The granules do not contain an alpha band, raster mask, or nodata values. The 
nodata sections are actually fully black pixels.

Any ideas?
