LAC 43:XXVII.1907. Linear Patterns

A. All linear patterns shall have a pattern angle of 90 degrees with respect to the line string or curve string represented. Lines digitized for linear patterning comprised of several elements (e.g., lines and curves) shall be created as connected strings. A connected string is a complex element comprised of single elements with common junction coordinates. B. Pattern interval (PI) is the map distance separating repetitive pattern elements at a standard pattern scale (PS) of 1.00 for 1" = 50' scale maps as defined for each respective feature element. Pattern intervals shall vary inversely for other mapping scales (i.e., PS = 0.50 for 1" = 100' scale maps, PS = 0.25 for 1" = 200' scale maps, and PS = 0.125 for 1" = 400' scale maps). Thus, a specified pattern interval of 0.80" at the 1" = 50' scale would be plotted 0.40" at 1" = 100' scale, 0.20" at 1" = 200' scale, and 0.10" at 1" = 400' scale.
