Haffner position paper accepted by NSF Workshop on Big Data and CyberGIS

Matt Haffner's position paper entitled "A Multi-Dimensional Topology for Crowdsourced Geographic Information" was recently accepted for presentation at the NSF Workshop on Geospatial Data Science in the Era of Big Data and CyberGIS in Urbana, Illinois on July 25-26. The workshop is sure to be a productive environment for GIScientists across the country. This is a great workshop to get involved with as well as contribute to! Should be a great meeting. Congrats Matt!
