GEOGRAPHIC INFORMATION including digital line graphs (DLGs) for transportation,
hydrography, and boundaries; digital elevation models (DEMs) for elevations; and digital
raster graphs (DRGs); will be acquired and (or) revised to create a temporally consistent
base for resource data. The project will acquire historical land use/land cover data for
selected time frames (1930s, 1950s, 1970s, and 1990s) that will be used to determine the
rate that infrastructure resources are being preempted by one another or by other
conflicting land uses.
Large amounts of geologic and hydrologic data exist in the
Infrastructure Resources Project study area. The Infrastructure Resources Project will
compile and convert some of those data to a digital format, and collect and interpret new
data as necessary. The geologic and hydrologic data will be integrated with land use data
in a Geographic Information System (GIS). Models will be developed that relate resource
occurrence to quality, quantity, and availability based on environmental and land use
impacts. The databases will be available in both map and digital format to enable users
with varying access to computers to explore land-use alternatives and assess the impacts
of various choices. |
