Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. To produce the digital map, we used existing 0.3-m-pixel imagery (color, color infrared, and panchromatic) acquired in 2003. This imagery did not cover the entire project area completely; therefore, we filled in the missing area with a 1998 U.S. Geological Survey 1-m-pixel, digital orthophoto quadrangle map. These images, in addition to ground-truthing, were used to interpret patterns of vegetation and land use. All of the interpreted and remotely sensed data were converted to geodatabases using ARCGIS© software. Draft maps were printed, fi eld-verified, reviewed, and revised as necessary. Due to the small size of AZRU, each point collected was revisited, resulting in a 100%-accuracy assessment of the evaluated area.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. To produce the digital map, we used 1:12,000-scale, true-color aerial photography acquired over several days in June 2004, in addition to the 2005 field plots. Both avenues were used to interpret the vegetation. All 34 map units were developed and directly cross-walked or matched to corresponding plant associations and land-use classes. All of the interpreted and remotely sensed data were converted to Geographic Information System (GIS) databases using ArcGIS© software. Draft maps were printed, reviewed, and revised.

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.

For Abó, the photography was acquired on April May 15, 2002 at a scale of approximately 1:3,000; for Quarai and Gran Quivira it was flown on April 2, 2003 at scales of 1:3,600 and 1:3000, respectively. The 2002-03 digital imagery has a base pixel resolution of 1.0 m. We also made use of statewide 1-meter resolution, true-color imagery from 2005 that became available in 2006 through the New Mexico Resource Geographic Information System. A 10 m spatial resolution USGS Digital Elevation Model (DEM) was used, in conjunction with ground data, to help discriminate between vegetation types based on elevation gradients and terrain. All imagery and other spatial data layers were compiled into a geodatabase and GIS using ArcGIS 9.3 (ESRI 2008).

A final vegetation map for Fort Matanzas National Monument was created to represent the vegetation occurring within the park during 2012. This product is 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 ground truthing points (2014), to create a draft vegetation map, performing an accuracy assessment (2015), and then using all the available information to create a final vegetation map (2018).

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.

The development of map units (map classes) and construction of a map legend is an iterative process that integrates the ecological vegetation classification units (plant associations, groups, etc.) described above with their spatial distribution as determined by the quality of the remote sensing imagery and on-the-ground reconnaissance work. Following NPS guidelines, the desired target is the development of map units that correspond to the plant-association level of the national classification, but this is contingent on being able to discern differences in the available imagery at that level using various remote techniques. Once a final supervised classification was completed, the resulting 45 classes were recoded into one of the 23 map units that best represented them. The image polygons developed from the object-oriented classification were imported as a feature dataset polygon layer in ESRI ArcGIS (v. 9.3), the file quality controlled, and topology built. The image polygons were then overlaid onto the recoded classification and the majority map unit was assigned as that polygon’s map unit.
