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 proportionate is having a proper relation between parts, such as size or ratio. An example of someone proportionate is a woman whose top half is sized in relation to her bottom half; proportionate size. Proportionate is defined as to even something out.
