This is the old CIA vector database, giving coarse geographical and political features. No altitudes, no names. A newer version may be purchased on CD-ROM.
worldmap.c was originally written by James Phillips at Marquette University and was adapted by Stuart Levy of the umn Geometry Center.
Changes by Andrew Daviel,
The worldmap package is available from ftp://geom.umn.edu/priv/slevy/worldmap.tar.gz
The worldmap.c, Makefile here are modified slightly and sph2wrl is a new program to generate VRML 1.0
The modified files are available at http://vancouver-webpages.com/pub/worldmap.mod.tar.gz
worldmap.c has been changed slightly to distinguish database types in the output. This information may be used to portray items in distinct colours. Mapping in Makefile (PostScript) and sph2wrl (VRML) assigns colours to types. A list of types is appended.
worldmap generates vector-based maps from a database. The resolution, lat/long coverage, and required features are configurable. No text information (placenames, etc.) is available, but may be merged from other sources quite easily using wwwInlines in VRML. worldmap can generate a variety of formats, including vector-based (fast) PostScript. An intermediate step is required to create VRML or OOGL output.
Colour codes required in PostScript header (see Makefile) and in sph2wrl are as follows:
101 Demarcated or delimited boundary 102 Indefinite or in Dispute 103 Other line of separation of sovreignty on land 201 Coast, islands and lakes that appear on all maps 202 Additional major islands and lakes 203 Intermediate islands and lakes 204 Minor islands and lakes 206 Intermittent major lakes 207 Intermittent minor lakes 208 Reefs 209 Salt pans -- major 210 Salt pans -- minor 213 Ice Shelves -- major 214 Ice Shelves -- minor 215 Glaciers 301 Permanent major rivers 302 Additional major rivers 303 Additional rivers 304 Minor rivers 305 Double lined rivers 306 Intermittent rivers -- major 307 Intermittent rivers -- additional 308 Intermittent rivers -- minor 310 Major canals 311 Canals of lesser importance 312 Canals -- irrigation type 401 Tectonic plates 418 Meridians 419 Parallels
