Summary
This dataset depicts vegetation and land cover for Klamath Marsh NWR. It was created using eCognition software and multiple sources of imagery. Field data were also collected at two different time to assist with image interpretation/classification. Details: This dataset was created by interpreting and classifying multiple image sources. These include: July 2005 2.5 meter Quickbird multispectral imagery, July 2005 ASTER 15 meter multispectral imagery, July 2006 Landsat 30 meter multispectral imagery, and December 2005 ASTER 15 meter multispectral imagery. Images were loaded into eCognition software which created polygons based on areas with similar image features. Statistics were then created for each polygon based on image brightness [...]

Images were loaded into eCognition software which created polygons based on areas with similar image features. Statistics were then created for each polygon based on image brightness values, texture and indices such as the Normalized Difference Vegetation Index. Field data collected in July 2006 and September 2007 were used to assist with image interpretation. Manual editing was also performed to improve the accuracy of the classification.
