MIL-PRF-89049A

Abstract

This specification defines the format for all National Geospatial-Intelligence Agency (NGA) products based on a standardized implementation of the Vector Product Format (VPF). Feature and attribute requirements, and other information for individual products are contained in the applicable specification sheets (see 2.2.1). Additional specification sheets may be added in the future.<br><u>Purpose. </u><br>This specification provides a description of the content, accuracy, data format, and design of all vector format products. Conformance to this specification will assure uniformity of treatment among all production elements engaged in a coordinated production and maintenance program for these products.<b><u>Intended Use:</u></b> VPF based products are intended for use as general purpose databases which can support GIS applications. Individual products provide a wide range of resolutions from high resolution to low resolution to support specific user needs. Refer to the individual product specification sheets for a more detailed description of intended use. Some of the products covered by this general specification will be military unique, because they are intended to support the planning and execution of military operations, and will contain data that is either classified, or that will have a distribution restricted to DoD only. Others may be made available to the public. Regardless of whether or not the product has application in the commercial sector, the format (directory structures, libraries, coverages, tables, table header information, etc.) of VPF data sets must be defined for application software to access and use the data.<br>
