The land-information officers proposed earlier (Committee on Geodesy, 1980) for designation by state and local governments.

SCOPE OF THIS REPORT

This report follows the lead of the Committee on Geodesy (1980) report, which recommends that local governments be the primary access points for local land information and that they maintain land data compatible with a multipurpose cadastre and transmit these data to higher levels of government when needed. Federal agencies can play an important leadership role by making their land-information systems consistent and compatible with each other to facilitate joint use of the data. Standards to assure this compatibility might be used as models by state and local governments.

With the wider availability of geodetic and mapping data in metric units, multipurpose cadastre development programs should consider the use of these units for all their elements and products. We recognize the tremendous costs that could be incurred in a program of conversion from existing English units into metric units. Hence, as initiatives that lead to the development of the various elements of the multipurpose cadastre are of major significance for this nation, these initiatives should not be deterred in any locality by the need to convert to the metric system. However, we would encourage that all cadastral data-management systems be designed to handle either English or metric units and that. whenever possible, metric products be made available.

Suggested Local Procedures for Building a Modern Cadastre

This report identifies procedures for the development of a modern cadastre. Standards are suggested where such standards are grounded in adequate prior experience. However, detailed specifications are provided only through references to other publications. Each of the procedures identified is well established in some locality in North America. The report provides a critical appraisal of the available standards and procedures, organized under the major components of the basic structure of a multipurpose cadastre:

  1. A reference frame consisting of a geodetic network;

  2. A series of current, accurate large-scale base maps;

  3. A cadastral overlay that delineates all cadastral parcels and displays a unique
