Online_Linkage: http://biology.usgs.gov/npsveg/ftp/vegmapping/scbl/scbl.zip Description: Abstract: The vegetation units on this map were determined through the stereoscopic interpretation of aerial photographs supported by field sampling and ecological analysis. The vegetation boundaries were identified on the photographs by means of the photographic signature and collateral information on slope, hydrology, geography, and vegetation in accordance with the Standardized national Vegetation Classification System (October 1995). The mapped vegetation reflects conditions that existed during the specific year and season that the aerial photographs were taken. There is a margin of error inherent in the use of aerial photographs. Therefore, a detailed ground and historical analysis of a single site may result in a revision of the vegetation alliance boundaries established through photographic interpretation. Purpose: Provide National Parks with the necessary tools to effectively manage their natural resources.

The data were revised by the contractor after the initial accuracy assessment was performed by re-interpreting some existing classes and adding two additional classes. A second revision was made by CBI personnel, changing interpretations of some classes with no further revisions in line work. The raw accuracy assessment data can be downloaded at http://biology.usgs.gov/npsveg/ftp/vegmapping/scbl/aa_data.txt. The contingency table derived from these data can be viewed at http://biology.usgs.gov/npsveg/ftp/vegmapping/scbl/aa_matrix.xls Logical_Consistency_Report: All polygon features are checked for topology using the ARC/INFO software. Each polygon begins and ends at the same point with the node feature. All nodes are checked for error so that there are no dangling features. There are no duplicate lines or polygons. All nodes will snap together and close polygons based on a specified tolerance. If the node is not within the tolerance it is adjusted manually. The tests for logical consistency are performed in ARC/INFO. All attribute codes and attributes have been checked for typographical and logical errors. Completeness_Report: All data in the project area were photointerpreted and digitized. This includes alliances/community association classes, density classes, height classes, pattern groups, water, and unvegetated/landuse. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The vegetation spatial data were visually fitted in small (2 inch square segments) to a custom-made orthophoto. The custom made orthophoto was ground tested for horizontal accuracy in three locations in and immediately adjacent to the park with Y-code (5 m accuracy) GPS with all test points falling within +/- 4-6 meters of the corresponding image location. The vegetation spatial data were test fitted to the orthophoto using a 2nd order polygon transformation using GRASS (Geographical Resources Analysis Support System) rectification software resulting in overall resiudals of +/- 5 meters.

Vegetation communities were idendified n the basis of their color, pattern, texture, and location on the landscape and lines were drawn around the communities. The photo interpreters had visited the monument and conferred with the ecologists who performed the vegetation classification and were familiar with the vegetation communities. Not all vegetation associations could be identified on the photography due to size constraints and complexity of the vegetation. Map classes were assigned in these cases and a cross-walk was made to the vegetation classification Process_Step: Process_Description: Accuracy assesment field data collection was performed independently of the mapping effort. 512 field plots were taken which were then compared with the attributes of the spatial data. A contigency table was developed comparing the attributes of 21 vegetation map classes with the field data developed by the accuracy assessement. Source_Used_Citation_Abbreviation: AA Report Process_Date: 1994 Process_Step: Process_Description: Aerial photography was taken of the Monument to serve as the basis for photo interpretation. Vegetation communities were identified on the aerial photography. Source_Used_Citation_Abbreviation: scbl Aerial Photos Process_Date: 1995 Process_Step: Process_Description: Ortho imagery was developed to serve as a registration base to transfer the photo interpreted polygons. The ortho imagery is registered to locations on the surface of the earth and image distorttions due to terrain relief have been eliminated. When the polygons registered to the aerial photos have been transferred and registered to the ortho images the polygons are registered to locations on the surface of the earth and terrnain distortions have been eliminated. Source_Used_Citation_Abbreviation: scbl orthophoto Process_Date: Unknown Process_Step: Process_Description: Classification of the vegetation communities was performed by ecologists based on the field data that were collected. Compiled data are assembled into a single file and transformed mathematically to a common abundance scale. The element classification process is implemented using quantitative approaches of ordination, clustering, and correlation depending on the information available. Multivariate analysis programs are used to examine the floristic patterns and their relationships to measured environmental variables. Despite their utility in synthesizing large data sets, many of the analytical programs identify vegetation patterns that are statistically but not ecologically meaningful. The quantitative analysis to determine vegetation patterns must be carried out under the guidance and review of experts who have a practical understanding of the ecological relationships in the field.

The upper levels of the hierarchy are based on the physical form or structure of the vegetation (physiognomy) and have been refined from the international standards developed by the United nations Educational, Scientific, and Cultural Organization (UNESCO). The two most detailed levels of the hierarchy are based on the species composition of existing vegetation (floristics) and reflect the phyto-sociological standards that were originally developed by European ecologists. The vegetation classification is continually advanced through the collection and analysis of new field data and will be greatly strengthened during the course of the USGS/NPS mapping efforts. Data file attributes include vegetation height, density, species, alliance, community element, and land cover. HEIGHT 1=< 0.5 meters 2=0.5 - 2 meters 3=2 - 5 meters 4=5 - 15 meters 5=15 - 35 meters 6=35 - 50 meters 7=> 50 meters 9=Not Applicable DENSITY 1=Closed/Continuous < 60% 2=Discontinuous 40% - 60% 3=Dispersed 25% - 40% 4=Sparse 10% - 25% 5=Rare 2% - 10% 9=Not Applicable Pattern 1,'Evenly Dispersed' 2,'Clumped/Bunched' 3,'Gradational/Transitional' 4,'Alternating' 9,'Not Applicable' Entity_and_Attribute_Detail_Citation: Grossman, D.
