Building on our earlier work determining
Connecticut specific impervious surface coefficients, the goal
of this research was to develop a more accurate set of land-cover-specific
impervious surface coefficients calibrated to low, medium and
high population densities. This was accomplished by increasing
our sample size to include more towns with planimetric GIS data,
and by calculating coefficients based not on town boundaries,
but on 1990 Census tracts. By using Census tracts we could use
consistent definitions for low, medium or high population density
areas. It also was a goal to use a quantitative measure rather
than a subjective classification such as rural, suburban and
urban.
A new set of impervious surface coefficients (designed to be used with our 1995
land cover data) and calibrated to population density was created.
These were then used in the Impervious
Surface Analysis Tool to generate information statewide.
