The GIS Portal, GIS Data Disclaimer for the hydrant data describes the fields and there significance. However, the “test date” field is indicative of when the hydrant was last tested. The “install date” is when the hydrant was physically installed at the street sidewalk.
The angle field is used to rotate the various hydrant symbols for display purposes.
