Ultimately, 19 map units were defined to describe all the land cover within the project boundary. This includes 13 that describe the vegetation. All of the interpreted and remotely sensed data were converted to Geographic Information System (GIS) databases using ArcGIS software. Draft maps were printed, field tested, reviewed and revised. During the summer of 2008 275 accuracy assessment (AA) data points were collected and used to determine the map's accuracy. After final revisions, the accuracy assessment revealed an overall thematic accuracy of 75%. The USGS Vegetation Characterization Program is a cooperative effort by the U.S. Geological Survey (USGS) and the National Park Service Inventory & Monitoring - Vegetation Mapping Program to classify, describe, and map vegetation communities in more than 270 national park units across the United States.

Accuracies improve from 40.0% and 25% for errors of commission and omission at fuzzy level 5 to 80.0% and 50.0% at fuzzy level 4. Map Unit 2 - Upland Post Oak Communities: As expected we see confusion between the two upland Oak map units (map units 2 and 3). Commission and omission errors for the Upland Post Oak map unit include the Upland Buckley Oak, Chinquapin Oak - Shumard Oak Ozark Forest and the Juniper Woodlands. The Chinquapin Oak - Shumard Oak Ozark Forest often grades into the more lowland types and we see this in the fewer but still notable errors for the upland Oak map units. The confusion with the Juniper type (Map Unit 13) is expected as there is considerable Juniper mixing in most wooded Map Units throughout the study area. Accuracies in this type improve dramatically at fuzzy level 4 giving us 84.8% and 93.1% for commission and omission errors respectively. Map Unit 3 - Upland Buckley Oak Communities: The Upland Buckley Oak community is primarily confused with the Upland Post Oak community and to a lesser degree the Chinquapin Oak - Shumard Oak Ozark Forest. A small proportion of the omission error is also found with both the Bur Oak - Shumard Oak Mixed Bottomland Forest and the Juniper Woodlands. Accuracies in this type improve at fuzzy level 4 to 89.7% and 72.2% for commission and omission errors respectively. Map Unit 4 - Chinquapin Oak - Shumard Oak Ozark Forest: Misclassification errors for this type was primarily with Upland Buckley Oak Communities and secondarily with Pecan - Sugarberry Forest and American Elm - (Sugarberry, Northern Hackberry) - Green Ash Forests. Errors were similar for both commission and omission. At fuzzy level 4, accuracy improves to 82.4% and 70.0% for commission and omission respectively. Map Unit 7 - Pecan - Sugarberry Forest: This map unit occurs rarely within the mapping area occupying less than 1% of the total mapped area. The few polygons mapped as Pecan - Sugarberry Forest occur primarily along Rock Creek and to the south of Veterans Lake. Because of the low frequency of this type only 5 AA points were assigned to this type. At fuzzy level 5 we see 0% accuracies for commission and omission increasing to 60.0% and 50.0% respectively. Confusion for this class was widespread and included the both upland oak communities, Chinquapin Oak - Shumard Oak Ozark Forest, and Eastern Cottonwood Temporily Flooded Forest Alliance for commission erros at fuzzy level 5. Map Unit 8 - American Elm - (Sugarberry, Northern Hackberry) - Green Ash Forest: This map unit also is rare within the mapping area and represents less than 5% of the total mapped polygons. Fuzzy level 5 accuracies are 44.8% and 54.2% for errors of commission and omission respectively. Errors are spread over most forested types for both errors of commission and omission. Map Unit 9 - Eastern Cottonwood Temporily Flooded Forest Alliance: This map unit was primarily confused with American Elm - (Sugarberry, Northern Hackberry) - Green Ash Forest for both errors of commission and omission. At fuzzy level 5 we have 60.0% and 30.0% for errors of commission and omission respectively. These accuracies improve to 80.0% for both categories. Map Unit 10 - Bur Oak - Shumard Oak Mixed Bottomland Forest: This map unit represents about 0.3% of the mapping area and has 0% accuracy at fuzzy level 5 for both errors of commission and omission. However, at fuzzy level 4 the accuracies rise to 75.0% and 60.0% for commission and omission errors respectively. Map Unit 13 - Juniper Woodlands: These woodlands make up about 13% of the mapped polygons for the project area. At fuzzy level 5, mapped accuracies where high at 76.7% and 71.9% for commission and omission errors respectively. At fuzzy level 4 the accuracy for commission error remains 76.7% but the omission error increases to 85.2%. Map Unit 19 - Disturbed Forb/Grasslands: This map unit comprises about 2.5% of the mapped area and is mostly commonly confused with the Upland Forb/Grasslands map unit. There is very little change from fuzzy level 5 to 4 or 3. Map Unit 22 - Emory's Sedge Herbaceous Vegetation: The accuracy of this type is difficult to determine given the exteremely low frequency with which it occurs within the mapping area. There is only one 1 acre polygon mapped as this type. Map Unit 24 - Cattail Wetlands: As with the Emory's Sedge Herbaceous vegetation above, the frequency of this type is extrememly low throughout the mapping area. Upland Forb/Grasslands: At fuzzy level 5 accuracy levels are low for almost all map units with the exception of map unit 28 (Upland Forb/Grasslands). This map unit maintains high accuracy for both errors of commission and omission.
