Important variables captured in this system include the source of water, vegetation class and subclass type (height and life form), and substrate. We used his system to classify extant wetlands for the big river floodplains analyzed. The following general process was used for classification and mapping. 1. Identify wetland system based on source of water. 2. Identify wetland class type based on vegetation height, and subclass based on life form (evergreen versus deciduous). 3. Create an index to water regime (a modifier applied at the class level) based on landform (sinks) and soil drainage class. 4. Execute mapping based on attribution of these variables (system, water regime, vegetation class and subclass) to image objects generated from LiDAR information. Water regime was defined based both on relative elevation, from which sinks were identified, and soil drainage class. Results were designed to provide an index to Cowardin’s water regime definitions. About 28.8% of the big river floodplains within the study area were uplands, and 71.2% was wetland. Seasonally flooded areas accounted for 16.4% of the study area, whereas relatively drier temporarily flooded and saturated areas made up 37.8% of the area. The temporarily flooded and saturated classes were liberally defined in order to circumscribe all areas that may support a water regime where wetlands could form. Thus, we are likely to have over-represented rather than under-represent the extent of wetlands on the big river floodplains.The goals for this data were to build upon work accomplished as a part of the Council's Ecological Approach to Infrastructure Initiative and to create a revised and improved wetland mitigation and restoration data layer for the Missouri and parts of the Mississippi River floodplain using LiDAR data. The focus on wetlands of big river floodplains was warranted because wetlands are subject to regulation, and because many agencies with means and need to mitigate activities, or oversee mitigation, are involved on the floodplains (e.g. the Army Corps of Engineers, Environmental Protection Agency, U.S. Fish and Wildlife Service, Natural Resources Conservation Service, and Missouri Departments of Transportation, Conservation, and Natural Resources).2010-04-12T00:00:00Urban development has occurred apace in some regions within the East-West Gateway study area, so we analyzed change in the region. We compared 2008 Landsat imagery to 2010 imagery using three dates (spring, summer, fall) for each year. The general procedure was as follows.
- Acquire spring, summer, and fall imagery for 3 Landsat path/rows for 2008 and 20010 to cover the study area
- Mosaic imagery by season
- Stack imagery by year (18 band stacks, one for 2008 and one for 2010)
- Mask out cropland using existing vegetation cover data to improve results for non-crop areas
- Use Erdas Imagine DeltaCue change detection module to classify each mosaic into 12 classes
- Concatenate the two stacks (144 potential change classes created), and manually identify classes that depict change
- Recode classes as change (1) or not change (0)
- Assign 2008 land cover class to all pixels with a value of 1 to determine which classes had changes in order to calculate statistics and summarize by countyNone planned-91.437839-89.99385138.98035038.083612U.S. Government Public Information Exchange Resource"EARTH SCIENCE","BIOSPHERE","TERRESTRIAL ECOSYSTEMS","WETLANDS","LACUSTRINE WETLANDS","", "EARTH SCIENCE","BIOSPHERE","TERRESTRIAL ECOSYSTEMS","WETLANDS","MARSHES","", "EARTH SCIENCE","BIOSPHERE","TERRESTRIAL ECOSYSTEMS","WETLANDS","PALUSTRINE WETLANDS","", "EARTH SCIENCE","BIOSPHERE","TERRESTRIAL ECOSYSTEMS","WETLANDS","RIPARIAN WETLANDS","", "EARTH SCIENCE","BIOSPHERE","TERRESTRIAL ECOSYSTEMS","WETLANDS","SWAMPS","", "EARTH SCIENCE","BIOSPHERE","VEGETATION","RECLAMATION/REVEGETATION/RESTORATION","","", "EARTH SCIENCE","HUMAN DIMENSIONS","HABITAT CONVERSION/FRAGMENTATION","REFORESTATION/REVEGETATION","","", "EARTH SCIENCE","HUMAN DIMENSIONS","HABITAT CONVERSION/FRAGMENTATION","URBANIZATION/URBAN SPRAWL","","", "EARTH SCIENCE","HUMAN DIMENSIONS","SUSTAINABILITY","ENVIRONMENTAL SUSTAINABILITY","","", "EARTH SCIENCE","HUMAN DIMENSIONS","SUSTAINABILITY","SUSTAINABLE DEVELOPMENT","","", "EARTH SCIENCE","LAND SURFACE","LANDSCAPE","RECLAMATION/REVEGETATION/RESTORATION","",""biotaenvironmentRestriction Code: other restrictions; Other Constraints: Although these data have been processed successfully on a computer system at the Missouri Resource Assessment Partnership (MoRAP), no warranty expressed or implied is made regarding accuracy or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty.
