Statewide land information mapping and records system; standards
Status: in_force

A. The state land office shall establish, promulgate, and maintain appropriate standards for a statewide land information mapping and map records system of all lands, private and public, within the state of Louisiana to promote and ensure compatibility, uniformity, and cost-effectiveness by public entities. These standards shall be developed to include the establishment of appropriate photogrametric or electronic mapping techniques and procedures which efficiently accommodate land information collection, maintenance, sharing, and retrieval. The department shall adopt these standards by rules adopted pursuant to the Administrative Procedure Act prior to January 1, 1991.

B. The standards required by Subsection A shall be employed by every parish governing authority or tax assessor undertaking the development of a land information mapping and map records system to assure that the assessment rolls of the parish contain a complete list of all taxable property. Only parish and tax assessor land information mapping and map records systems complying with these standards shall be eligible for state financial aid.

C. Information contained in the land information system shall not constitute or be considered as a legal representation of immovable property.

The origin of coordinates is at the intersection of the meridian 92 degrees 30 minutes west of Greenwich and the parallel 30 degrees 30 minutes north latitude. This origin is given the coordinates: x = 1,000,000 meters and y = 0 meters.

(b) The "Louisiana Coordinate System of 1983 South Zone" is a Lambert conformal conic projection of the North American Datum of 1983, having standard parallels at north latitudes 29 degrees 18 minutes and 30 degrees 42 minutes along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 91 degrees 20 minutes west of Greenwich and the parallel 28 degrees 30 minutes north latitude. This origin is given the coordinates: x = 1,000,000 meters and y = 0 meters.

(c) The "Louisiana Coordinate System of 1983 Offshore Zone" is a Lambert conformal conic projection of the North American Datum 1983, having standard parallels at north latitudes 26 degrees 10 minutes and 27 degrees 50 minutes, along which parallels the scale shall be exact. The origin of coordinates is at the intersection of the meridian 91 degrees 20 minutes west of Greenwich and the parallel 25 degrees 30 minutes north latitude. This origin is given the coordinates: x = 1,000,000 meters and y = 0 meters.
