Dan Majka

Sr. Cartographer / Analyst

Dan designed and updates TNC Maps, but has not yet created any of the actual maps or datasets on the site. He performs spatial analysis and cartography for The Nature Conservancy's North American Region science team, and previously served TNC's Arizona conservation science team from 2007-2012. Before joining TNC, he created a GIS toolkit for designing wildlife corridors, spent a year designing wildlife corridors in Arizona, and wrote his Master's thesis at Purdue on using species distribution modeling to understand localalized bird distributions in the TilarĂ¡n Mountains of Costa Rica. He doesn't normally write in the third person.

Acknowledgments

This site would not have been possible without earlier work from Jon Fisher, Dave Smetana, and Danielle Conboy. Eric Coffman and Kyle Burford in TNC's Conservation Systems and Services group helped with some javascripty elements of the site.

All of the infrastructure to publish this data was set up by a large group of staff from the Conservancy's Technology and Information Systems team, and many maps and data were created with a generous software donation from ESRI.

For TNC Staff

If you are interested in publishing a map, please visit the spatial data publishers community on the TNC intranet, which has guidance and a place to ask questions and receive support.
