A. It is well
				  recognized that a substantial amount of work expended by state and local
				  government relates to the location, characteristics, resources, use and value
				  of land. Parish assessors and political subdivisions of the state have
				  developed various systems to assist in the collection, development, storage and
				  retrieval of land data. Traditionally these have been manual systems which
				  include an abundance of records consisting of paper maps, survey plats,
				  property record cards, log books and index files. A variety of numbering
				  schemes and procedures have evolved to maintain such systems. The combination
				  of these various records, numbering schemes and procedures form the framework
				  of many land information systems currently in use.
B. The public entities that maintain these
				  systems recognize many shortcomings. Existing hard-copy maps are of
				  inconsistent scale, land information cross-referencing is inadequate, retrieval
				  is time-consuming, and many of the existing records are old, deteriorating,
				  voluminous, and outstripping available storage space. On their own initiative,
				  many parishes and agencies have introduced improvements such as updated map
				  products, revised numbering schemes, mechanized file storage and retrieval,
				  microfilm records, and various computerized information systems.
				  Notwithstanding these improvements, fundamental underlying problems such as
				  inconsistent map accuracy, ambiguous title descriptions, and dissimilar record
				  indexing systems continue to impede efficient and effective data
				  manipulation.
C. The Louisiana Land
				  Information Mapping and Map Records Standards set forth herein have been
				  structured to promote and ensure compatible, uniform and cost effective
				  development of a modern Land Information System (LIS) to accommodate the
				  collection, maintenance, sharing and retrieval of land information by
				  authorized public entities throughout the state.
D. The primary focus of these standards is
				  directed toward the development of accurate, complete and compatible geographic
				  base map products which form the framework and foundation to facilitate
				  subsequent land parcel mapping activities. Major topics addressed under these
				  standards include uniform requirements for map accuracy, ground control
				  densification, aerial photography, photo laboratory procedures, analytic aerial
				  triangulation, digital mapping, geographic base map preparation, land parcel
				  mapping, associated relational database development, and standardized map
				  feature elements. These standards outline the orderly development of each major
				  phase of work to be accomplished in connection with the implementation of a
				  Land Information System and establish minimum criteria necessary for acceptable
				  completion of each phase.
E. It is
				  recognized that the implementation of the various phases of work set forth
				  herein will normally require several years to accomplish. For this reason, it
				  is the intent of these standards that usable LIS products developed during the
				  course of implementation be made available to authorized public user agencies
				  as soon as practical prior to final completion. This early dissemination of
				  land information data should help to promote efficient sharing, retrieval and
				  utilization of available land information in the most timely and cost-effective
				  manner possible.
