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]
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.
