The In practice, because of normal word lengths and byte addressing, the only alternatives are 4 bits X, 4 bits Y or 8 bits X and 8 bits Y; the use of 16 and 16 has no advantage over absolutes. It appeared to the writer that 8 bits X and 8 bits Y was most advantageous for data output from the system and carto graphic storage. This allowed for vector lengths of up to ±127X and ±127Y elements (or for sharp corners as low as IX and 0Y) to be entered, so that vectors could be at resolved angles of less than 1°.
Preferably the original work will have been scribed and this is normal for most map series made in the last twenty years. Copy work from the original must be properly controlled in quality. 2) Line weights should be within a specified range S system for example allows a 4:1 3) ratio). Gaps between lines should be greater than a specified minimum 4) (the U-of- (usually 1 or 2 p i x e l s ) . Unwanted data should be absent or removed opaquing). (usually by A. g. CGIS.

Data users continue to apply existing methods, develop and implement new auto mated techniques, and should be as well informed as possible of the discipline issues related to the analyses performed. The following paragraphs briefly describe spatial data characteristics and software/hardware features as they relate to both SDI discipline and ADP issues. A. Spatial Data Characteristics As previously defined, spatial data include both content data and locational identifiers of spatial entities, and may be four dimensional.
