This represents the difference between the recorded horizontal coordinates of features and their true positions. Absolute horizontal accuracy is expressed as a circular error at 90 percent probability (-
18、9p). The absolute horizontal accuracy of VMap Level O for all features derived from Operational Navigation Charts (ONCs) is 2,040 meters rounded to the nearest 5 meters at 90 percent circular error (CE), World Geodetic System (WGS 84). The absolute horizontal accuracy of VMap Level O for all feature
19、s derived from Jet Navigation Charts (JNCs) i5 4,270 meters at 90 percent circular error. 3.1.2 Absolute vertical accuracy. This represents the difference between an assigned elevation and the true elevation at a specific point. In this comparison, both elevations must be referenced to mean sea leve
20、l (MSL). A points elevation may be determined through interpolation of the digital contour file or it may be listed as a vertex coordinate of a feature. For VMnp Level O derived from cartographic source, vertical elevation values shall be filled with the VPF null (NaN), as defined in the VPF Mil- St
21、andard Cection 5.5.2, unless an elevation value is provided on the source material. The absolute vertical accuracy u VMap Level O is the same as for the original ONC and JNC lithographs at 90 percent linear error (LE), mean sea level. a. Contour accuru. The accuracy of contours collected from ONC so
22、urce is 2152.4 meters. b. -. The accuracy of spot elevations collected from ONC source is 230 meters. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-V-89039 3.1.3 pslative accuracy.

The horizontal datum for this VMap product shall be WGS84 as identified in DMA TM 8350.2. 3.2.2 Vertical datum, The vertical datum for this VMap product shall be mean sea level (MCL). 3.3 Data density levels. a. VMap Level O data are collected at a den
24、sity af detail that approximates that of DMA Standard small scale products. b. Based on its data collection density, if VMap Level O data are to be output in hard-copy om, the appropriate scale or this output is at 1:1,000,000. 3.4 Database source and extent. The geographic extent of the VMap Level
25、O product is global and consists of multiple regional databases. VMap Level 0 data from standard DMA source products are derived from the feature content defined in the associated military specification. Exceptions to the deEined feature content may be found in this specification. 3 .s lont inu i tv
