------ About ------
Tanner Arrington | Columbia, South Carolina
I spent the previous decade as a GIS Manager for the South Carolina Department of Natural Resources.
I like high quality cartography, scripting with Python, and modeling GIS workflows. I've worked in just about every corner of Esri's ArcGIS platform, and also with QGIS and other open-source tools.
I collaborate with the great folks at Community Geographics.
If Freewheel Maps can help your organization or company with GIS, please send me an email to get in touch:
