COHYST Land Use Mapping

The Platte River Cooperative Hydrology Study is a multi-agency effort that seeks to improve the understanding
of the hydrological conditions in the Platte River watershed in Nebraska upstream of Columbus, NE.
Comprehensive and current information on land cover and land use are critical to COHYST since
hydrologic conditions change in relation to crop dynamics. The Center for Advanced Land
Management Information Technologies (CALMIT) has developed historical and modern land
cover databases for the COHYST region based on Landsat-5 and Landsat-7 Thematic Mapper
(TM) satellite imagery and ancillary data. Future COHYST modeling efforts will require examination
of 2005 agricultural land cover patterns. This aspect of the project is currently underway.
