SUBJECT CATEGORY:
Publication of North American Datum of 1983 State Plane Coordinates in Feet in Maine
DATES: Individuals or organizations wishing to submit comments on the Publication of North American Datum of 1983 State Plan Coordinates in feet in Maine, should do by January 11, 2008.
DOCUMENT SUMMARY:
The National Geodetic Survey (NGS) will publish North American Datum of 1983 (NAD 83) State Plane Coordinate (SPC) grid values in both meters and U.S. Survey Feet (1 ft = 1200/3937 m) in Maine, for all well defined geodetic survey control monuments maintained by NGS in the National Spatial Reference System (NSRS) and computed from various geodetic positioning utilities. The adoption of this standard is implemented in accordance with NGS policy and a request from the Maine Department of Transportation, the Maine Society of Land Surveyors, and the Maine GIS Stakeholders.
SUMMARY:
North American Datum of 1983 State Plane Coordinates in feet—; Maine,
SUPPLEMENTAL INFORMATION
Abstract
IN 1991, NGS adopted a policy that defines the conditions under
which NAD 83 State Plane Coordinates (SPCs) would be published in feet
in addition to meters. As outlined in that policy, each state or
territory must adopt NAD 83 legislation (typically referenced as Codes,
Laws or Statutes), which specifically defines a conversion to either
U.S. Survey or International Feet as defined by the U.S. Bureau of
Standards in Federal Register Notice 595442. To date, 48 states have
adopted the NAD 83 legislation however, for various reasons, only 33
included a specific definition of the relationship between meters and
feet. This lack of uniformity has led to confusion and misuse of SPCs
as provided in various NGS products, services and tools, and created
errors in mapping, charting and surveying programs in numerous states due to inconsistent coordinate conversions.
