MIL-PRF-89049/9, PERFORMANCE SPECIFICATION SHEET: VECTOR VERTICAL OBSTRUCTION DATA (VVOD) (24 MAY 2004) [USE MIL-PRF-0089049/9 IN LIEU OF MIL-PRF-89049/9]., This specification defines the content and format for the U.S. National Geospatial-Intelligence Agency (NGA) Vector Vertical Obstruction Data (VVOD) product. References to the VVOD specifications in this document assume use of both the general specification and this specification sheet. The VVOD is a vector-based digital product that portrays vertical obstruction data. The VVOD also functions as a mission specific data set designed to support Geographic Information System (GIS) applications. The VVOD database contains data concerning known vertical obstructions worldwide. The vertical obstruction data stored in the database includes all of the manmade and natural vertical obstructions known by NGA projecting above the Earth?s surface which are sufficiently tall so as to pose a hazard to powered flight, both manned and unmanned. The specification provides a description of the content, accuracy, data format, and design of the VVOD database.
