Summary

The dataset includes Land Use/Land Cover types throughout the Chenier Eco-Region in Southwest Louisiana. Using the 2015 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 LULC categories. This process involved stitching together more reliable sources for specific categories to apply to higher resolution (75) segmentation product. Reference datasets [...]

Purpose

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. This effort encourages communication and implementation of restoration and habitat enhancement actions within water sheds. 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. This product is a refined version of land cover data across the Western Gulf Coastal Plain which includes additional land use categories at a higher resolution (10m). This work was conducted in collaboration with the TPWD, and the Gulf Coast Prairie Landscape Conservation Cooperative.
