Description / Abstract: This document defines the minimum user requirements applicable to the origination and publication of terrain and obstacle data from creation through the entire life cycle of the data. Data processing should be accomplished in accordance with RTCA DO-200B/EUROCAE ED-76A. This document provides a minimum list of attributes associated with the terrain and obstacle data and a description of associated errors that may need to be addressed.

The numerical values in Section 4 are defined to accommodate the most stringent known application requirements, and not on a basis of acquisition cost. The accuracy, integrity, and resolution requirements for primary means of navigation have not been considered in this document.

Additionally, guidance material is provided to assist the certification process of an application using terrain and obstacle data.

Land use/land cover database requirements have not been specifically addressed in this document.

PURPOSE AND SCOPE

Introduction

This document was written to identify requirements for terrain and obstacle data.

Data originators require the quality characteristics to be defined, including specific numerical values, in order to provide data for use in applications. Appendix C provides some illustrative application examples.

Certification authorities and the end users require information to ensure that terrain and obstacle data satisfy the intended applications.
