This paper explains the characteristics of Transverse Mercator projections, the relationship of plane grids to USGS map cells, and the reasons DRG's and other USGS digital products are projected on the UTM.
âº If two amounts are proportional, they change at the same rate so that the relationship between them does not change: 1  Weight is proportional to size. 2  How far you go is directly proportional to how fast you go (= as one thing increases, the other increases at exactly the same rate).
The definition of proportional is something that has a relatively correct relationship of size or that is appropriate.1  An example of something proportional is a woman's tiny feet to her short stature.
