Request
Borough Presidents' Topographical Bureau Maps - Borough Presidents' Topographical Bureau offices scattered around the city contains publicly accessible legal grade maps, monument and benchmark maps, and street ROW title maps. These are hard copy maps and only the Bronx Borough Presidents office posts scanned PDF's online. This system is archaic and needs to brought up to the 21st century.
What I would love to see is a shapefile containing ROW polygons with ROW width, and title status among other data, and monument, benchmark, and legal grade points, containing not only point location in NYS NAD83-LIF and other obvious data, but also lat-long, and northing-easting of their respective map projection borough coordinate system (Borough Topographic Origin for Manhattan, Bogart System for Staten Island, West Bronx and East Bronx System for the Bronx, and respective Brooklyn and Queens Topographic Systems for Brooklyn and Queens).
Thank you
