The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of four land-water products (2005, 2008, 2012, and 2015). The resulting matrix has 16 possible classes defined by the combination of land and water categories on those four dates. The intended use of this data set is to provide information to aid efforts in the conservation, restoration, creation, and enhancement of Louisiana's coastal wetlands. The land-water data is used to measure the occurence, locations, and rates of land loss/land gain for CRMS Site 0589. 2005 2008 2012 2015 publication date Complete None planned -92.828224677 -92.8178964422 29.6692966963 29.6602488374 None CRMS DOQQ land-water wetland mapping restoration marsh protection coastal cartography Geographic Information System ISO 19115 Topic Category imageryBaseMapsEarthCover USGS Metadata Identifier USGS:593875d8e4b0764e6c5d6bfc None Louisiana Geographic Names Information System State of Louisiana It is strongly recommended that these data are directly acquired from the U.S. Geological Survey, Wetland and Aquatic Research Center and not indirectly through other sources which may have changed in some way.

Refer to individual years of land-water data for accuaracy information. This data represents the landscape composition on the four dates of acquisition (DOA) of the imagery. Land area in this highly dynamic environment is a very fluid parameter, and normal environmental variability can lead to variability in this measure from day to day. The accuracy of the horizontal positions is based on the accuracy of the georeferenced data source (which can be USGS DOQQs, DEMS, flight line center points, and/or calibration reports). The sources used vary from project to project. All USGS Mapping products adhere to the National Mapping Accuracy Standard. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable.
