Section XXVII-101 - General

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.
