cov# Binary Primary Key. The unique identification number of a graphic (line) feature. 
cov-id Binary Foreign Key. The identification number of a garbage repository (in the 
GARBAGE T table). Several graphic features may represent the same 
garbage repository, but measured at different times. 
grb perim |Float (12,3) |The distance around the boundary of the subject item (garbage 
repository) in meters. 
grb area |Float (12,3) |Indicates the total area of the subject item in squared meter [m^]. 
grb width |Float (7,3) |Indicates the width dimension of the subject item in meters. 
grb lengt |Float (7,3) |Indicates the length dimension of the subject item in meters. 
validity Char (1) Validity of the graphic feature to represent the last measured state of the 
garbage repository. (“F" = previous measured state, “T” = last measured 
state). 
insp date [Date The date of inspection.
