[GeoNode-users] geonode-users Digest, Vol 41, Issue 33

Fri Jun 15 00:37:56 PDT 2018

Dear everyone,
I would like to nominate myself to be part of GeoNode PSC project, 
principally as a beta-tester.
Over the last few years I have developed small applications in Python, C 
++, javascript and and Java concerning data acquisition and processing 
with spatial information using gdal libraries. These small applications 
have specific purposes and process sensitive data, therefore they are 
not published on open source repositories.
Of course, I also make myself available to write code, if there is a 
willingness on the part of the Directors.

Sincerely,

*//*Carmine Massarelli
