Recommendations for DSP 
(1) Landsat data are suitable for future Maryland land cover inven 
tories, and can also be used to augment MAGI System data. For 
example, areas encoded only by functional use in MAGI can also 
receive a cover type label obtained from Landsat data. Likewise, 
the MAGI System data can be used to augment the Landsat results, 
by digital overlay and incorporation of some MAGI categories, such 
as transitional. 
(2) DSP should use the MAGI System adjusted primary and secondary land 
use (P' + S') acreages. This will entail software modifications to 
enable operational use of the (P' + S') computation. 
(3) The reorganized DSP land use scheme developed in this project 
should be useful for other Maryland remote sensing projects.
