A final vegetation map for Canaveral NS was created to represent the vegetation occurring within the park during 2012. This product represents the final of four steps necessary to produce an accurate vegetation map based upon aerial photographs. This includes the determination of the community element global (CEGL) codes (2008) and acquisition of aerial imagery (2012), using the aerial imagery, with five ground truthing points (2014), to create a draft vegetation map, performing an accuracy assessment (2016), and then using all the available information to create a final vegetation map.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Converting delineations to a digital format involved four main procedures: a) preparation of manuscript maps b) input of the spatial data: c) populating of the attribute tables, and d) conversion to GIS. Each step included many quality control steps. Maps were prepared by pin-registering a clean sheet of mylar to each photo and transferring delineations to the new overlay in ink. Each manuscript map was edgematched to the adjoining sheet. Each photo was numbered, and each polygon on the photo was numbered in sequence. An attribute table was created containing a field each for the photo number, polygon sequence number, land use code, layer number, stature type, height, density, and floristic composition attributes.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. ECognition software was used to circumscribe visually homogeneous polygons. Multiresolution segmentation (Scale parameter: 25, Shape: 0.2, Compactness: 0.2) was applied to four bands of 1 meter (3.3 ft) National Agricultural Imagery Program (NAIP) imagery and normalized difference vegetation index (NDVI) derived from the imagery. We used eCongition to calculate eighty-one variables and attributed the variables to the polygons. These variables summarized attributes of the topographic relationships of the polygons, reflectance values derived from aerial photography, surficial geologic composition, and vegetation height.

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. A geodatabase containing various feature class layers and tables was constructed to show the locations of vegetation types and general land cover (vegetation map), vegetation plot samples, AA sites, project boundary extent, and aerial photographic centers. The feature class layer for the CUIS vegetation map provides 1,005 polygons of detailed attribute data covering 15,163.4 hectares, with an average polygon size of 144.7 hectares. Of the area mapped, 816 polygons (81% of all polygons) represent natural/semi-natural vegetation types in the NVCS, encompassing 9,542.8 hectares (62.9%) of the total map extent.

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. The project geodatabase links the spatial vegetation data layer to vegetation classification, plot photos, project boundary extent, AA points, and the PLOTS database. The geodatabase includes USNVC hierarchy tables allowing for spatial queries of data associated with a vegetation polygon or sample point. All geospatial products are projected using North American Datum 1983 (NAD83) in Universal Transverse Mercator (UTM) Zone 16 N. The final GUIS vegetation map consists of 1,268 polygons totaling 35,769.0 ha (88,387.2 ac). Mean polygon size is 28.2 ha (69.7 ac). Mean polygon size, excluding water, is 3.6 ha (8.9 ac).

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The interpreted polygons were manually transferred to overlays that were registered to the base maps. Map unit attributes and appropriate physiognomic modifier codes were added to a second overlay. The overlays were subsequently rechecked for accuracy. Each overlay of transferred data was scanned using a large format sheet fed scanner at a resolution of 400 dots per inch. The resulting Tagged Image File Format (TIFF) images were then converted to a grid using ArcInfo (Version 7.2.1 Patch 2, Environmental Systems Research Institute, Redlands, California). For data produced with the DOQ base maps, the converted grid was projected to UTM Zone 15 using North American Datum of 1983 (NAD83).

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. Color infrared (CIR) aerial photographs of the park at 1:12,000 scale were acquired by Aero-Metric, Inc. on May 11–12, 2012. These photos were scanned and converted to digital orthophotographs at 0.3-meter (1-ft) resolution before they were delivered to the National Park Service. Digital orthophotographs and hardcopy photographs in both film transparency and paper print formats were provided to the University of Georgia Center for Geospatial Research. A total of 165 photos in five flight lines were required to cover Canaveral National Seashore

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Polygons representing vegetation or land use map classes were delineated on-screen in an ArcView environment. The project used the program standard minimum mapping unit of 0.5 ha with few exceptions. The 18,633 map polygons representing 70 natural and semi-natural vegetation map classes cover 134,377 ha (332,053 acres, 91.6% of the project area). Map classes representing 1,720 polygons of unvegetated bedrock, talus, wash channels or sand sheets total 11,515 ha (28,454 acres; 7.8% of the project area). Nine map classes describing 634 polygons of land use categories, including roads, ranch developments and NPS facilities, total 862 ha (2,130 acres; 0.6% of the project area). Average polygon size across all map classes is 7.0 ha (17.3 acres). The most frequent vegetation map class is the Pinyon-Juniper / Mesic Shrubs Woodland Complex (Map Class 16 / W-PJME) with 5,122 polygons covering 42,197 ha (104,271) acres or 28.7% of the project area.
