Using ArcGIS COGO tool for ROW / Easement digitizing from old plats (using their bearings and distance calls) that used what a veteran of the county says were 'made up" coordinate systems in Maryland. Several cities supposedly had their own "made up" coordinate systems.
Does this veteran's story sound correct? I have contacted several people at state archives (source of the old plats) but no one there has answers to where / what these old coordinate systems are.
Is it possible in ArcGIS COGO or QGIS to recreate these "made up" coordinate systems, do the bearings / distance digitizing, and then transform them for use in Maryland State Plane 1900?
