atnxcture of lhe DMA Digital Production System.
MINI-TOPO consists of two overlapping data
structures: cartographic and spatial. The
cartographic structure contains all attribute
hdomxstbn, relatlonahlps between Iaatures and
feature components, and ties to the underlying
apatiil structure Ieval. The spatial structure
aasocistes the cartographic !aalures 10 lheir
exact geographic placement. Also known as
the Mapping, Charting, & Geodesy Feature
Data Exchange Structure (MCGFDES).

relief maps or models the datum may or may
not be sea level but is consistent within a relief
