GRASS GIS Raleigh meetups 2016

Meetups focused on GRASS GIS, how to use it, how to extend it, and how to contribute to it are organized about once a month in Raleigh, NC, USA. Usual meeting location is the Hunt library, a great space at North Carolina State University campus. Meetups started with a group of people contributing or interested in contributing to GRASS GIS which met at the end of 2015 in Raleigh and decided to meet regularly in the following year. This is a page to organize meetings and to record what was done or discussed during the meetings.
