Re: [Geotools-devel] Interesting Martin Davis has released Proj4j

[Ugo T. <ugo...@ia...>]

Hello,

just thought I should let the GT people know, deegree has a more-or-less 
new projection library which also supports proj4 string format.

I'm not suggesting cooperation, I'm throwing this in as a fact. (I often 
ask why the Java world needs 4 logging frameworks (java.logging, log4j, 
slf4j and  apache's-i-can-log-'em-all - forgot anyone?)

Soon we'll have more project libraries in Java then logging frameworks. :-)

Cheers,

Ugo
