Typically GIS and geodata nerds are male. Anyhow, 99.9 % of our contacts, freelancer sign ups, comment writers here on the blog are boys. But where are the GIS girls and women? There must be thousands of well educated, very interested hackathon-proven GIS ladies out there. In order to getting in touch with that obviously shy species, I formulated 4 theses about GISgirls. Hopefully many active GIS and geodata girls (and women) will read that and comment in the bottom section. I would be very happy to get your feedback!
