28、 I iy” i3 MIL-STD-600006 1. SCOPE 1.1 Scope. The vector product format (VPF) is a standard format, structure, and organization for large geographic databases that are based on a georelational data model and are intended for direct use. VPF is designed to be compatible with a wide variety of applicat

29、ions and products. VPF allows application software to read data directly from computer-readable media without prior conversion to an intermediate form. VPF uses tables and indexes that permit direct access by spatial location and thematic content and is designed to be used with any digital geographi

30、c data in vector format that can be represented using nodes, edges, and faces. VPF defines the format of data objects, and the georelational data model provides a data organization within which software can manipulate the VPF data objects. A product specification corresponding to a specific database

31、 product determines the precise contents of feature tables and their relationships in the database. In this context, each separate product or application is defined by a product specification and implemented by using VPF structures. . The information contained in this 1.2 BgDliCabJlJty II standard s

DETAILED REQUIREMENTS 5.1 -. This section describes the necessary com

38、ponents of vector product format,. conceptual components of the VPF data model (see appendix A for an overview describing the data model). Section 5.3 contains definitions of the data structures implemented ir1 VPF, The encapsulation of VPF field types, table construction, and ii=i each file is cont

39、ained in exactly one directory. File names must be unique within a directory. A file referenced by a directory is said to be contained in that directory. A file contained in a directory may be referenced by a special form of its name called a pathname (because it contains the location path to the fi

40、le). A pathname has the following form: where : indicates that the enclosed name element is to be replaced with the actual text string indicated. VPF uses the backslash character () as the generic pathname directory separator. For platforms requiring a different separator, software will replace the

41、backslash with the appropriate separator character. For example, if a file named ROADS.LFT is contained in a directory named URBANAREAS, and the separator is (), the resulting pathname would be: URBANAREASROADS.LFT Directories are themselves files, so they may be contained in other directories. They

42、 are referenced by pathname the same way as other files. Thus, if URBANAREAS is contained in LIBRARY1, the resulting pathname would be: LIBRARYlURBANAREAS Finally, pathnames may be combined. Since the directory that contains a file can be contained within a directory itself, it is necessary to have

43、a form of file name that uniquely identifies that file contained within that directory (file names, while unique within a directory, are not unique between directories). For our example, that form would be: 5.2.1.2 UbJes. In the VPF data model, the table is the organizational structure for all data

44、content. All tables in a VPF database share a common basic structure; this structure, which is described in the VPF table components section below (5.2.1.3), is mandatory for a3.1 VPF tables. 21 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD

45、-600006 MC W 999991iL 01i34004 3 c 1 MIL-STD-600006 By definition, a VPF table must include at least the basic structure. Optionally, a VPF tabie can also include two additional structures: the narrative table and the varfabie- length index file. n the VPF data model, all geographic phenomena are mo

46、deled by VBF tables or by tables derived from a VPF table. A table derived from a VPF table is one that possesses all the properties of a WF table but also has additional properties that support other speeifie functions. The primitive table and the attribute table are examples of derived VPF tables.

47、 A derived table can also be further specialized to satisfy a particular need. derived from the attribute table, for example. Figur 4 graphically shows a VPF table and three derived tables. The VPF table is drawn with an oval; all derived tables are differentiated from VPF tables and from each other
