Hartley, S.B., Allain, L.K., and Baldwin, H.Q., 2017, Grassland priority rankings model for the Western Gulf Coastal Plain of Louisiana: U.S. Geological Survey data release,


The dataset includes Land Use/Land Cover types throughout the Chenier Eco-Region in Southwest Louisiana. Using the 2015 National Aerial Imagery Program (NAIP) dataset (1m) as the basemap, E-Cognition image objects were derived from the multiresolution segmentation algorithm at 75 and 250 segments. Attempts to refine the data training methods using E-cognition, to extrapolate automating categories of this information to the entire map resulted with exceedingly low accuracy. Therefore, a raster was produced by piecing together several data resources, which provide reliable data for specific LandUse/LandCover (LULC) categories. This process involved stitching together more reliable sources for specific categories to apply to higher resolution [...]

Collaborative landscape conservation planning is largely limited by the quality of spatial data which can be applied to decision support tools to inform conservation decisions. Conservation entities across the Western Gulf Coastal Plain are taking a collaborative, strategic, landscape scale approach to conservation planning. Land cover datasets available within this geography hinder the efficiency of such efforts due to low resolution quality and limited details associated with land use categories. In collaboration with the Texas Parks and Wildlife Division (TPWD), and the Gulf Coast Prairie Landscape Conservation Cooperative, we have produced a spatial dataset that refines a version of land use land cover data across the Western Gulf Coastal Plain to produce a high resolution priority ecological systems ranking model. The model ranks priority landscapes for grassland management. The product was designed using high resolution land cover, extensive ground truthing, and review of soil and elevation influence on vegetation associations.
