Hello Everyone!
My company is hosting a time-limited mapathon for GIS day this year:
https://www.lgeo.co/eventsWe have some additional prizes to be announced before the event as well...
While the event isn't limited to using open-source software, submissions using open-source may get a special mention.
Also, feel free to check us out, either as a place to work, or as a potential consultant. We use open-source alongside the various commercial options.
Thanks
Cameron
