Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. the draft final map was subjected to a heads-up screen digitizing edit using the most recent aerial photography. Accordingly, we accessed recent imagery through 2012 Microsoft Corporation Bing Imagery, available via ESRI ArcGis 10.0. As with all Bing imagery, the exact image date is not provided, but a search of the Digital Globe library indicates three possible dates: 2009-01-13, 2011-11-18, 2012-01-09, or a combination thereof. We think that it is not likely that the 2012 imagery had been posted to Bing, and that the 2011 imagery is the most likely candidate. We were also able to bring directly in additional 2009 New Mexico county imagery, and 2005 NAIP color-infrared and natural-color imagery at 1 m resolution. During the final edit, the thematic composition and number of Level 1 and 2 map units were finalized and the final map product produced using NPS cartographic standards. While the minimum mapping requirements were at 1:24,000 scale with map unit delineations or polygons at 0.5 ha or larger, most of the final line work was completed at an operational scale between 1:12,000 and 1:3,000. Hence, polygons down to 0.25 ha were often maintained. For final map production, adjacent polygons of the same class were merged. Final map products included the geodatabase and a 1:44,000 poster map at Level 1 and 2.

These data were combined with existing plot data (Cully 2002) to derive an initial list of potential types. Additional data and information were gleaned from a field visit and incorporated into the final list of map units. Because of the park’s small size and the large amount of field data, the map units are equivalent to existing vegetation associations or local associations/descriptions (e.g., Prairie Dog Colony). In addition to vegetation type, vegetation structures were described using three attributes: height, coverage density, and coverage pattern. In addition to vegetation structure and context, a number of attributes for each polygon were stored in the associated table within the GIS database. Many of these attributes were derived from the photointerpretation; others were calculated or crosswalked from other classifications. Table 2.7.2 shows all of the attributes and their sources. Anderson Level 1 and 2 codes are also included (Anderson et al. 1976). These codes should allow for a more regional perspective on the vegetation types. Look-up tables for the names associated with the codes is included within the geodatabase and in Appendix D. The look-up tables contain all the NVC formation information as well as alliance names, unique IDs, and the ecological system codes (El_Code) for the associations. These El_Codes often represent a one-to-many relationship; that is, one association may be related to more than one ecological system. The NatureServe conservation status is included as a separate item. Finally, slope (degrees), aspect, and elevation were calculated for each polygon label point using a digital elevation model and an ArcView script. The slope figure will vary if one uses a TIN (triangulated irregular network) versus a GRID (grid-referenced information display) for the calculation (Jenness 2005). A grid was used for the slope figure in this dataset. Acres and hectares were calculated using XTools Pro for ArcGIS Desktop.

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. Forty-two polygons were mapped within the project boundary: 27 at the main unit and 15 at the Adamsville proposed expansion area. In total, 15 distinct types were identified across the study area. Seven of these types are Anderson Land Use Classes or variations thereof; the others are natural vegetation classes following the NVCS. Map classes were described at the alliance or association level; where known, alliance descriptions also include recognized associations. Due to the small area involved in this project, and to its relatively simple floristic attributes, there is a one-to-one correspondence between the map classes presented here and the community types described. A total of 35 species were recorded during the sampling efforts. Alliances and associations marked with (P) are proposed, not yet accepted into the NVC. In addition, summarized local descriptions, with example satellite image/signatures and representative photos for each alliance or association, follow this section.

The De Soto National Memorial vegetation map was made in UTM, NAD 83, zone 17N coordinates with a minimum mapping unit of 400m2. Aerial imagery from January 2007 and LIDAR imagery from 2003 were used for initial polygon development. These polygons were further refined with field data from December 2007 and June 2009. The final vegetation map has a total of 21 mapping classes and 56 polygons.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Photo interpretation was conducted through an on-screen heads-up digitizing method using ArcMap. The study area was divided into several modules. The individual modules were interpreted using the primary and supplemental imagery, reconnaissance and relevé data, and other ancillary data, including elevation contours and fire history. Each polygon was assigned the appropriate attribute code string (mapping classification types, conifer, hardwood and shrub percent cover, and land use). A total of 6,141 map polygons representing 34 vegetation map classes (including tree and shrub cover), 14 land use map classes and 7 miscellaneous classes were developed for the PINN vegetation mapping project. Of the 6,141 mapped polygons 115 were assigned to both a land use class and a vegetation class. Average polygon size across all map classes is 3 ha (7.3 acres). Natural and semi-natural vegetation classes cover 17,953 ha (44,362 acres), or 98.6% of the project area. Land use polygons including ranch developments, agriculture and Park facilities cover 250 ha (617 acres), or 1.4 % of the project area.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Ultimately, we developed a geodatabase containing four feature classes: vegetation points (containing vegetation sample points and AA sites), vegetation and land use polygons (showing locations of vegetation types and general land features), 1:12,000-scale CIR aerial photograph centers, and project boundary extent. Included in the geodatabase are several tables providing a suite of supporting information, from classification crosswalks to detailed sampling data. All geospatial products are projected in the Universal Transverse Mercator (UTM), Zone 16, using the North American Datum of 1983 (NAD83).
