GIS-based classification and comparison of playa lakes as wetlands on the southern high plains

Analysis of the level of agreement between methods of delineation will test the null hypothesis Ho = that there is no difference between the use of USGS 7.5 minute topographic sheets, wetlands inventory maps, and SCS soil surveys for mapping playas on the Southem High Plains. Acceptance of Ho indicates that agreement probably exists between the three criteria used to identify wetlands on the southem high plains. Rejection of Ho indicates the validity or acceptance of the altemative hypothesis HA = some degree of difference exist between criteria used to identify wetlands on the SHP.
