Is there software that takes legal description text as input for conversion to some computer friendly GIS format? For example:
Those portions of the North Half of the Southeast Quarter and the Northeast Quarter of the Southwest Quarter of Section 5, T.13S., R.4E., S.B.B.&M., according to United States Government Survey approved February 24, 1876 described as follows: Beginning at a 1 1/2 inch iron pipe having coordinates Y = 329,169.63, X = 1,895,486.55, set for the center of said Section 5, thence along the East line of said Southwest Quarter, S.4°11'18"W., 24.65 feet; thence S.56°02'45"E., ... All bearings and coordinates are referred to the California Coordinate System, Zone 6.
More specifically, open source software.
Assuming that info that would be broad enough such as "S.B.B.&M." & "California Coordinate System, Zone 6." can be addressed but realizing that a reference to something like a specific adjacent parcel recorded locally would require manual effort.
