BY USING THIS WEBSITE OR THE CONTENT THEREIN, YOU AGREE TO THE TERMS OF USE. The primary purpose of this data is to be used by Oakland County
Planning and Economic Development Services, other County departments,
and and local communities for planning purposes. The two major uses are
cartographic output and creating summaries at various spatial extents.
The intent of this feature class was to provide a
very general representation of a hard copy 1966 land use map. The
spatial accuracy and number of vertices used to represent each feature
was limited by the intended purpose of the data.
The land use features were heads-up digitized from a 1966 land
use map that was scanned and georefereneced using each section corner as
a control point. The features were digitized at a scale not greater
than 1:15,000, one square-mile section at a time. After the entire
county was completely digitized, the features were dissolved based on
the Landuse.
Right-of-Way was burned in to the final feature class using the
following process. First, the current RoadCenterline feature class was
modifed to reflect roads in 1966 using the scanned 1966 land use map and
1963 orthophotography as a reference. Next, the road lines were
buffered at specified distanced based on the RoadCode attribute from
RoadCenterline to create polygons. Major Roads were split into two
types (Perscriptive Easement and Dedicated) based on if the adjacent
property was platted prior to 1966. According to the Oakland County
Register of Deeds, in 1966 Oakland County was recording documents in
liber 120. For the purpose of this feature class it was assumed that
simultaneous conveyances recorded in liber 120 or earlier existed in
1966. Major roads that intersected or were adjacent with these
simultaneous conveyances were classified as Dedicated and the remainder
of Major Roads were classified as a Perscriptive Easement. The buffer
distances, representing half the total Right-of-Way width, used for each
road code are listed below:
Minor Road - 30 feet
Major Road (Perscriptive Easement) - 33 feet
Major Road (Dedicated) - 46.5 feet
State Highway - 46.5 feet
U.S. Highway - 46.5 feet
Interstate - 60 feet feet
These Right-of-Way widths generally approximate
those that actually existed in 1966 and are not intended to indicate the
exact width of a specific Right-of-Way. All areas completely
surrounded by Right-of-Way such as between directions of travel of a
boulevard or interstate or the area inside of a freeway interchange were
manually attributed as Right-of-Way.
Water features were burned in the final feature class using a
modified version the of the Oakland County Waterbody feature class.
This data was modified to reflect waterbodies in 1966 using the 1966
land use map and 1963 orthophotography as a reference.
Lastly, the features that intersected community boudaries were split
using the Identity tool to increase cartographic and analytic
performance.
