SCOPE a.
2、 This specification establishes the first edition military specifi- cation requirements for the Defense Mapping Agencys (DMA) Tactical Terrain Analysis Data Base (TTADB) . b. The DMA Terrain Analysis Program is a dynamic program; consequently, this manual may not identify all necessary specification
3、s encountered in the production of terrain analysis data bases. Supplementary instructions will need to be generated in areas that require modification of these specifications. 1.2 Purpose. Conformance to these specifications will assure uniformity of treatment among all mapping and charting element
4、s engaged in a coordinated production and maintenance program for this product. 1.3 Securitv. a. I 1.3.1 Security classification . The securityclassification ofthe products generated by the use of these specifications will be the lowest category practicable. When it is necessary to assign a security
5、 classification to the product, it will be accomplished in accordance with established national security procedures.

11、rescribed in paragraph 3.11, Marginal Information; (3) with legends as shown in Appendix D; and (4) with symbology as illustrated in Appendix B. b. The legends for each thematic overlay (See Appendix D, Legends Appendix) will normally be the same for all sheets in the project and must include all ca
12、tegories foundintheproject area whether or not they appear on an individual sheet. . Individual sheet (basemap) coverage limits 3.7.2 -limits and insets shall be as defined by the Area Requirements and Product Status (ARAPS) file. In turn, the TTADB overlays shall be positionedto the corner geograph
13、ic coordinates of the base map to which they are keyed. Insets on the base map shall be shown in the same way and in the same position on the TTADB overlays. The additional corner ticks shall be shown as per the base map. I 3.7.3 Neatlines . Cartographic detail within the TTADB overlays shall not ex
14、tend beyond the neatline of the base map to which they are keyed. Features which cross the neatline shall be truncated exactly at the neatline, with the remaining portion of the feature portrayed on the adjoining sheet. 3.7.4 Wtrah . All TTADB overlays, both initial and final, shall be punch registe

Refer to Appendix C, Size limits for 1:50,000 Map Sheet, for overall dimensions of map sheets. 3.8.2 Unit of measure. a. The Unit of Measure for the TTADB is Metric; however, both English and Metric Units are pr
16、ovided in Appendices A, B, C and I of this specification. b. Specification measurements are normally given at reproduction scale, i.e. , 1:50,000. 3.8.3 Minimwm sizes a. The minimum size polygon shown on most of the overlays shall have an areal extent of at least 20 square millimeters at map scale (
17、50,000 square meters groundarea) withaminimumwidthgreaterthanorequaltolmm (50mgrounddistance). The smallest polygons shown are on the Surface Drainage Overlay, where open water and islands have an areal extent of at least 2 square millimeters (5000 square meters ground area) with a minimum width of
18、at least lmm (50m ground distance). For longnarrowpolygons, straight or curved, the length is the centerlinedistance measured from one end to the other. (See Figure i). b. The minimum lengths shown vary with different thematic overlays, but in general range from no minimum length to 5mm (250m ground
19、 distance) . Normally, all features less than 2mm (100m ground distance) in length are treated as point features, whereas those equal to or greater than 2mm (100m ground distance) are considered linear features. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license f

Most of the linework, symbols, data information holders, etc., on the Surface Drainage, Transportation, and Obstacles Overlays shall also have a lineweight of 0.30mm (0.012 inches). Leader lines are the major exception; all leader lines (no matte
