This application was created to support the Mapping Existing Vegetation on Prince of Wales Island story map.

The Prince of Wales Existing Vegetation mapping project encompasses over 4.2 million acres of Southeastern Alaska—2.3 million of which are terrestrial. This map was designed to be consistent with the standards established in the Existing Vegetation Classification and Technical Guide (Nelson et al. 2015), and to provide baseline information to support project planning and inform land management of the Prince of Wales and surrounding islands. The final map comprises seven distinct, integrated feature layers: 1) vegetation type; 2) tree canopy cover; 3) trees per acre (TPA) for trees ≥ 1’ tall; 4) trees per acre for trees ≥ 6” diameter at breast height (dbh); 5) quadratic mean diameter (QMD) for trees ≥ 2” dbh; 6) quadratic mean diameter for trees ≥ 9” dbh; and 7) thematic tree size. The dominance type map consists of 18 classes, including 15 vegetation classes and 3 other land cover types. Continuous tree canopy cover, TPA, QMD, and thematic tree size was developed for areas classified as forest on the final vegetation type map layer. Geospatial data, including remotely sensed imagery, topographic data, and climate information, were assembled to classify vegetation and produce the maps. A semi-automated image segmentation process was used to develop the modeling units (mapping polygons), which delineate homogeneous areas of land cover. Field plots containing thematic vegetation type and tree size information were used as reference for random forest prediction models. Important model drivers included 30 cm orthoimagery collected during the height of the 2019 growing season, in addition to Sentinel 2 and Landsat 8 satellite imagery, for vegetation type prediction. Additionally, detailed tree inventory data were collected at precise field locations to develop forest metrics for Quality Level 1 (QL1) Light Detection and Ranging (LiDAR) data. LiDAR information was acquired across approximately 80% of the project’s land area. Continuous tree canopy cover and 2^nd order forest metrics (TPA and QMD) were modeled across the LiDAR coverage area, and subsequently, extrapolated to the full project extent using Interferometric Synthetic Aperture Radar (IfSAR) as the primary topographic data source.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Vegetation map development for KNRI has somewhat different protocols than for other Parks. Normally photointerpretation is preceded by extensive field work which includes plot selection and vegetation sampling using detailed descriptions which are subsequently analyzed using ordination and other statistical techniques. The data are then summarized and association descriptions are assigned to each plot or, if the association is previously unrecognized, then a new association name is assigned. Subsequently, the plots locations are compared to its photographic signature and a photointerpretive key is developed. Given the very small size of KNRI and the extensive historical impact and alteration of the vegetation a simplified technique was used. NatureServe developed a list of potential vegetation types prior to any field work. This list was referenced during the field visit and modified after comparison of site characteristics and vegetation descriptions. Aerial photographs were viewed prior to the field visit and areas of like signature were differentiated. All vegetation and land-use information was then transferred to a GIS database using the latest grayscale USGS digital orthophoto quarter-quads as the base map and using a combination of on-screen digitizing and scanning techniques. Overall thematic map accuracy for the Park is considered 100% as all interpreted polygons received a filed visit for verification.

We provide a shortcut to the land cover map WMS service provided by the Ministry of Environment's Environmental Spatial Information Service. A land cover map is a type of thematic map, a spatial information DB that classifies the form of surface topographic features according to certain scientific criteria, Color Indexes areas with similar characteristics, and then expresses them in the form of a map. Since land cover maps best reflect the phenomena of the surface, they are widely used in estimating non-point source pollution loads based on surface permeability, urban planning based on biotope map creation, simulation of flood damage to downstream areas when dam water gates are released, climate and atmosphere prediction modeling, environmental impact assessments, etc. They have a status as a scientific basis for establishing environmental policies by the central and local governments, and are used as various research materials in related academic circles. *The concept was established in 1985 by the European Environment Agency (EEA) in the CORINE (Coordination of Information on the Environment) project, a project to build a European land cover map to comprehensively collect and manage vast amounts of information on the land conditions of member states in the EU. Based on this, classification criteria suitable for Korea were determined, and in 1998, the Ministry of Environment built the first large-scale land cover map for the South Korean region.

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. Following the vegetation plot data analysis, the preliminary vegetation map was edited and refined to produce a revised preliminary vegetation map prior to thematic accuracy assessment. Using ArcMap 9.2 (ESRI 1999-2006), polygon boundaries were revised on screen based on the plot data, field observations, classification analyses, aerial photography signatures, and topographic maps. Each polygon was assigned the NVC Community Element Global (CEGL) code of a preliminary vegetation association based on the information sources listed above. Second, third, and fourth CEGL code choices were entered in cases of uncertainty, or for polygons representing mosaics of two or more types.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Following the vegetation data analysis, the formation-level vegetation map was further edited and refined to develop an association-level vegetation map. Using ArcView 3.2, polygon boundaries were revised onscreen based on the plot data and additional field observations. Each polygon was assigned one of eight vegetation association types based on plot data, field observations, aerial photography signatures, and topographic maps. An aerial photograph interpretation key for the vegetation associations was created. However, several associations could not be distinguished reliably by aerial photography signatures alone. Plot data, field observations, and topographic maps were relied upon in these circumstances to inform the polygon delineation and association name assignments. After the vegetation association map was completed, the thematic accuracy of this map was assessed.

Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The MANZ spatial database and map layer was produced by CTI from 2010 imagery using 21 map units that were directly cross-walked or matched to their corresponding rUSNVC plant association/alliance or land cover types. The final map layer was assessed for thematic accuracy by creating contingency tables and the final overall accuracy of the map layer was determined to be 96% with a Kappa value of 95%. The vegetation mapping was conducted at MANZ in two phases. The first phase conducted by the USGS Fort Collins Science Center created the primary vegetation and associated spatial data layers using the 2005 NAIP Manzanar NE DOQQ imagery (acquired on September 3, 2005 from the Cal-Atlas Geospatial Clearinghouse at http://atlas.ca.gov/). Preliminary mapping was conducted by the USGS through a semi-automated process using a combination of the ENVI Feature Extraction Module (ITT Visual Information Systems, 2008) and ArcGIS software (ESRI, 2008).
