I first heard about OpenJUMP last month when one of your users posted a bug
report on the Apache Commons Imaging JIRA system (see
https://issues.apache.org/jira/browse/IMAGING-265). The bug is fixed now
and I am grateful for the folks here who brought it to my attention.
Anyway, based on that posting, and some of the JPP documentation, I get the
impression that Commons Imaging is used in at least some capacity in
OpenJUMP. So I thought that I would mention another relatively new feature
in the Commons Imaging API: the ability to read floating-point elevation
data from USGS 3DEP Cloud-Optimized GeoTIFF files. This capability was
introduced in the latest release of Commons Imaging
(commons-imaging-1.0-alpha2). I don’t know if it is something the project
can take advantage of, but I thought I would bring it to your attention.
If you would like more information on the feature, I’ve just posted an
article and some sample code showing how to use the API for creating
shaded-relief imagery. While OpenJUMP already has its own shaded-relief
capability through its Sextante plugin, I think that the article might be
of interest to folks on this mailing list because it provides background on
the USGS GeoTIFF files as well as discussing the algorithms for
shaded-relief rendering. If you are interested, you may access it at

Thanks, and good luck on the JUMP Pilot Project. It is an impressive
project and I look forward to studying it further.
