    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.

    This is great data Tim, thanks!

    Two questions:
    1. What is the significance of the test and installation dates? I am seeing lots of entries from the years 1899 and 1970. Do those values have any meaning?
    2. Is the angle attribute indicative of the hydrants position relative to the street?
