Mark Rees | City of Wentzville

GIS analyst Mark Rees leads a team that provides mapping support to the City of Wentzville’s Water Division. 

During his tenure at the city, Mark has used ArcGIS Enterprise to migrate data collection from a paper-based to an electronic format. Implementing ArcGIS Field Maps allowed for the seamless integration of GIS technology to increase operational efficiency across all programs that the Water Department manages. Mark has also used Python to automate various processes and provide up-to-the-minute information about program status and data collection efforts.
