The Arkansas Geographic Information Office contracted
for an ADOPII (Arkansas Digital Orthophotography Project II) project where
Earth Data captured1foot – 3 foot data for the entire state of Arkansas in
the spring of 2006. The data is available on GeoStor.
Benton County is an active partner in The National Map
program providing aerial photography, elevation data, streets, etc and
maintaining that data in order to streamline local government activities.
The US Geological Survey has a need to update the National Spatial Data
Infrastructure. Benton County has become a front-line steward/editor of the
National Hydrologic Dataset or NHD. With the current high resolution
digital ortho aerial photography acquired in 2006 and LiDAR data acquired in
2004 the Benton will be updating the existing medium and high resolution NHD
data for Benton and Washington Counties from 1:100,000 and 1:24,000 scales
to 1:4800 scale. This will update water sources such as streams, lakes,
rivers, ponds and the flow of the water. This update will assist in the
analysis of water resources for flow, flood inundation, impacts of a spill,
etc. Benton and Washington Counties are in a high visibility and high risk
area with the tremendous amount of growth that is being experienced coupled
with the water source for 1 out of 8 Arkansans coming from the Beaver
Reservoir located in the area.
