Open Source GIS – The Swiss Army Knife of Mapping Tools for the Arborist and Urban Forester

Online registration is now closed - please register at the door.


Geographic Information Systems (GIS) has been an invaluable tool for Urban Foresters, Engineers, Planners, and many other disciplines for quite some time, however largely it has been in the hands of the few “tech-oriented” people who took interest in it. Additionally, proprietary software and training have been costly, thereby limiting the adoption of these amazing tools for daily management of the urban forest. QGIS, an open source GIS platform, provides a rich array of easy-to-learn tools for mapping, inventory, analysis, and so much more. This one-day seminar will teach you how to download and install the free software, find and create geographic data, and use that information to solve everyday problems in practical scenarios common to arborists and urban foresters.
