Texas-Oklahoma Land Cover Enhancement

Texas-Oklahoma NAIP Image

The land cover maps of Oklahoma and Texas will be seamlessly joined to create a single map. Edge matching must be performed to accurately join the two maps. We will use unique database codes associated with mapped ecological systems types to ensure matching names between Texas and Oklahoma data sets in order to create a unified data set. We will address gaps between the state data sets, overlaps between the data sets, and differences in naming and mapping concepts between the data sets.

In addition to gaps and overlaps, differences are related to land cover disagreement, digital soil mapping discrepancies, and ecological systems modeling concept differences. These will be addressed using new field data, new remote sensing data, and/or hand modification of digital soil map unit polygons.

We will create an enduring features (ecological site type, geolandform) data set for Oklahoma that is similar to, and essentially seamless with, the enduring features data set we created for Texas. We will use the enduring features data set to create a land cover coding key for map updates. The key will identify the prevailing historic ecological system for each enduring feature, and the ecological system associated with every major land use/cover type.

MoRAP will work with the Texas Parks and Wildlife Department (TPWD) and the Oklahoma Department of Wildlife Conservation (ODWC) to collect field data on grasslands in the panhandle of Texas and adjacent Oklahoma.
