These data were converted from the originally delivered Microsoft Access PLOTs database from the Vegetation Mapping Inventory Project of Jean Lafitte National Historical Park and Preserve. These comma-delimited data tables contain(s) vegetation mapping plot classification and accuracy assessment data, as well as summary information about the data itself. If a table is empty, then it was empty in the original database.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. To map the vegetation and land cover of JELA, 26 map classes were developed. Of these 26 map classes, 24 represent natural (including ruderal) vegetation types, most of which types are recognized in the USNVC. For the remaining 2 of the 26 map classes, 1 of the map classes represents a USNVC cultural subclass type for developed areas, and the other map class represents a non-USNVC type for nonvegetated open water. Features were interpreted from viewing 3-band digital aerial imagery using digital onscreen three-dimensional stereoscopic workflow systems in geographic information systems; digital aerial imagery was collected during July 25–26, 2014. The interpreted data were digitally and spatially referenced, thus making the spatial-database layers usable in a geographic information system. Polygon units were mapped to either a 0.5-hectare (ha) or 0.25-ha minimum mapping unit, depending on vegetation type. A geodatabase containing various feature-class layers and tables presents the locations of USNVC vegetation types (vegetation map layer), vegetation plot samples, verification sites, AA sites, project boundary extent, and aerial image centers and flight lines. The feature-class layers and related tables for the vegetation map layer provide 2,463 polygons of detailed attribute data covering 11,058.5 ha, with an average polygon size of 4.5 ha when physiognomic cover-density modifiers are not considered; with modifiers, the vegetation map consists of 2,867 polygons, with an average polygon size of 3.9 ha. The vegetation map includes the administrative boundary for the Barataria Preserve within JELA and the Fleming Plantation area.

This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here. Sets of both true-color (TR) and color infrared (CIR) aerial imagery were acquired in July 2014 for the JELA vegetation mapping project using a plane-mounted digital camera. This imagery became the primary source for image interpretation and mapping. The aerial imagery was collected at a pixel resolution of 15.24 centimeters The JELA flight plan consisted of 20 flight lines. To achieve a successful set of aerial imagery for vegetation mapping purposes, 3 flight missions were flown, collecting a total of 659 frames of imagery. The initial flight mission collected CIR imagery and was flown on July 25, 2014. Because of local weather patterns in the available collection window, some intermittent cloud coverage captured by the imagery was unavoidable. Efforts were made to ensure complete coverage by repeating the flight mission for a portion of the flight plan on July 26, 2014; this second flight mission repeated 10 flight lines. A total of 500 frames of CIR imagery were collected with the 2 CIR flight missions. The third flight mission collected TC imagery covering the entire study area on July 26, 2014.
