It comes as IBM binary tapes - I don't remember how many, but it was several boxes full of tapes. (It has been almost 10 years since I worked with them.) The following is abstracted from a report that described our conversion of WDBII to ``NICKEL'' file format. The resulting VAX binary files filled most of a 300 MBy disk pack, so any 13 MBy file would be a substantially reduced version of the original.

(415) 486-5181 or (FTS) 451-5181 December, 1981 The World Data Bank, produced by the U.S. Central Intelligence Agency, is a geographic base file containing digitized latitude and longitude coordinates for the major geographic features of the world. Version I, released several years ago, will not be further discussed here. Ver- sion II originally consisted of five sets of files, corresponding to the major continental divisions of the world. Each geographic area consists of four separate files, containing (a) coastlines, islands, and lakes (b) rivers (c) international boundaries (d) internal boun- daries (e.g. states, provinces, etc.). Conventional digitizing methods have been used in producing World Data Bank II. From enlarge- ments of the best available maps (or aerial photographs), points are digitized every 0.01 inch by moving a stylus along coastlines, politi- cal boundaries, etc. Arbitrary 7-digit codes, assigned to each chain, are used to identify data for later editing. Boundaries (e.g. state boundaries) are digitized only once. However, if a state boundary corresponds to a river, the river is digitized separately and the two are forced to agree (unless the river changed course after the state boundaries were defined). The WDBII was digitized from maps which were 1:3,000,000 scale resulting in approximately 6,000,000 points. (See article by Anderson, Angel and Gorny, given at the Symposium on Topo- logical Data Structures for Geographic Information Systems, Harvard University, Laboratory for Computer Graphics and Spatial Analysis, Oct. 1977.) AREA FILE NAMES (Table 1) The following table gives the area file names, their approximate area coverage and contents. These area file names correspond to the file names on tape. The ``chains'' are polylines, the largest of which is about 9000 points. area numb min max min max feat- geographic file ch- long long lat lat ures area name ains ---- ---- ---- ---- ---- ---- ------- --------------- AF301 3 11 15 35 37 ISLANDS NORTH AFRICA (INCL.
