Mapper since: January 16, 2008

Living in Managua, Nicaragua since fall of 2013 after living in Haiti for three years. I'm interested in mapping quite broadly from the side of personal hobby to institutional uses to OSM on really any topic. I also love helping other individuals, communities or organizations to use or/and contribute to OSM.

If you want to contact me please send me a note via the form below, email me at jaakko (├Ąt) helleranta {dot} com or see my profile via for other ways to contact me. My Nica mobile is +505-8131-0729 (Movistar).

I can understand and communicate French and Spanish somewhat ok -- but don't ask me to explain you detailed things in neither language unless we are meeting in person!

P.S. If you read this and you don't have any information on your own OSM profile, please consider adding something about you. It's an excellent way to build trust and connection withing the OSM community.
