MIL-PRF-89014A

Abstract

a. This specification establishes the second edition military specification requirements for the Defense Mapping Agency's (DMA) Interim Terrain Data (ITD) and Planning Interim Terrain Data (PITD). This document specifies the format, content, and product design of ITD and PITD, which are unsymbolized digital data sets. <br>b. The DMA Terrain Analysis Program is a dynamic program. This document identifies specifications encountered in the production of the ITD, and PITD thematic files. Supplementary instructions may need to be generated as this product evolves. Modifications will be handled through Configuration Management procedures. <br>Conformance to these specifications will assure uniformity of treatment among all mapping and charting elements engaged in a coordinated production and maintenance program for this product. <br>The ITD and PITD data sets are, respectively, based on the level of detail represented in the 1:50,000/1:100,000 scale Tactical Terrain Analysis Data Base (TTADB) and the 1:250,000 scale Planning Terrain Analysis Data <strong><b>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to : Director, Defense Mapping Agency, ATTN: ATC, 8613 Lee Highway, Fairfax, VA. 22031-2137 by using the Standardization Document Improvement Proposal (DD Form, 1426) appearing at the end of this document or by letter.</b></strong> Base (PTADB). Both ITD and PITD have an enhanced transportation network, and are provided in a standardized digital format. ITD and PITD are portrayals of analyzed attributes of terrain of features (both natural and man-made) that are of significance to tactical (ITD) and planning (PITD) military operations. <br>a. For the remainder of this document, the term ITD will be used generically to describe both ITD and PITD. Where it is important to distinguish between the two, this document will do so. Likewise, the term TADB will be used generically to describe both TTADB and PTADB. <br>b. These specifications apply to all ITD produced by the Defense Mapping Agency and those produced for the Defense Mapping Agency as a result of either government contract or unit tasking. <br>c. These specifications apply to all activities involved in the preparation and maintenance of ITD. <br>a. ITD is a product developed to satisfy the armed services short-term and mid-term requirements for digital terrain analysis data. <br>b. In the case where TADBs are used as the primary source, ITD will reflect the specification current at the time of TADB collection. In all other cases, the currently configured baselined TADB specification will be used. <br>c. ITD is designed to use the Defense Mapping Agency Feature File (DMAFF) coding scheme (see <a>2.1.2</a>.a.), and the Standard Linear Format (SLF) for Digital Cartographic Feature Data (see <a>2.1.1</a>), for data format and structure. <br>d. ITD is independent of the method of its production. The production methods result in a standard product that meets the requirements of this specification. <b><u>Intended Use:</u></b> ITD is a product developed to satisfy the armed services short and mid-term requirements for digital terrain analysis data. <br>
