GIS (Geographic Information Systems) is a division of the IT (Information Technology) department. The GIS division provides software, training, data development, application development and technical support to the county departments.
ArcGIS REST Services (ArcGIS Server) allow you to load GIS data directly from the County's servers into an ArcMap / ArcGIS Pro session on your computer. This means the data will always be up-to-date; no need to re-download a shapefile. You'll be using the same data that Henderson County staff are using.
