[Geoserver-users] NullPointerException with ContrastEnhancement

[Stefan Ziegler]

Hi

I try to apply some contrast enhancement to a geotiff file but I get some
null pointer exceptions. This happens with GeoServer 2.24.2 and 2.25.0. Any
idea what goes wrong? Perhaps not a supported compression or something
similar? The sld works without the ContrastEnhancement section or without
the ColorMap. Thanks.

Stefan

Re: [Geoserver-users] [EXTERN!]: LOG4J Version in GeoServer

[Stefan Ziegler]

There is now a fork of log4j named reload4j: https://reload4j.qos.ch/ It is a 
drop-in replacement and the project aims to fix the most urgent issues.

Subject: Re: [Geoserver-users] [EXTERN!]: LOG4J Version in GeoServer

Our customers are demanding to support the latest version of log4j in 
Geoserver, I mean the latest 2.* without vulnerabilities because log4j 1.* is 
EOL.
On the Geoserver website I found this (13-12-2021):

We are also aware that Log4J 1.2.17 is an “End Of Life” (EOL) project, and are 
actively looking for funding to perform an upgrade to more recent versions of 
them. All new logging libraries have a different API and a different 
configuration file layout, with potential backwards compatibility issues, so 
this will be likely done on newer versions of GeoServer (2.21.x).

What is the status at this moment?

Thanks,
Ron

No, this is not a new release but the same release with some files
removed and a way of preventing people from shooting themselves in the
foot because they can no longer configure the culprit appenders.

After inspection of the new jar file you can add a suppression for false
positives like





^log4j:log4j:1\.2\.17$
CVE-2019-17571
CVE-2020-9488
CVE-2021-4104

Re: [Geoserver-users] Footprints (location) with Image Pyramid

[Stefan Ziegler]

Answering myself: The footprint files belong to the same folder where the
raster files are stored.

[Geoserver-users] Footprints (location) with Image Pyramid

[Stefan Ziegler]

Hi

I'm struggling using a footprints shapefile with some raster files
published as image mosaic. I created a footprints.shp with gdaltindex. The
footprints.shp has one attribute called "location". The value of location
is the raster file name, e.g. "2593_1226.tif".

In which directory has this footprints.shp to be stored? The layer
directory in the data dir?

As far as I understand the documentation I do not need a
footprints.properties file?

Since It's not working, can I see some log output? I tried geootools
develop profile, but couldn't spot any footprints specific output in the
logfile?

Thanks for any hints.

[Geoserver-users] WMS raster rendering interpolation quality

[Stefan Ziegler]

Hi

Geoserver offers three options for raster rendering: nearest neighbor,
bilinear, bicubic. I made some tests with a single band (black and white)
geotiff with internal overviews.

Nearest neighbor: Rendering when zoomed out is as expected not very nice.
https://drive.google.com/file/d/18MXxA67lmfJFOmM_7qtRf9XUPploSamS/view?usp=sharing

Bilinear: It looks like nearest neighbor when zoomed out (which irritates
me a bit).
https://drive.google.com/file/d/1lGSxUC4VNEi5NpVoV7Q1Ury2vif3tf5I/view?usp=sharing

Bicubic: This is where i get black dots when zoomed out
https://drive.google.com/file/d/1iODH8-gEGGhBNfckQZ7XnXMnqyZDSVGW/view?usp=sharing

When I use the image pyramid plugin to publish the file and preprocess the
file with gdal_retile I get much better rendering results with all three
methods. Bicubic example:
https://drive.google.com/file/d/1Fjml6_FckcuGSVwdRglT30HhzLe_BWaT/view?usp=sharing

Is there a way to achieve the same rendering quality without preprocessing
the data (or using the image pyramid plugin respectively)?

Original file can be found here:

best regards
