Input Standards

MAP: Optional. Two-character code. Default: blank character blank character

Definition

 
MAP, 006

If a map specifies a type of projection, enter the two-character code in Proj and the projection statement in field 255 subfield ‡b. If a map does not specify a projection, leave Proj blank.
