San Juan Island National Historical Park Vegetation Mapping Project - Spatial Vegetation Data

The National Park Service (NPS) Vegetation Inventory Program (VIP) is an effort to classify, describe, and map existing vegetation of national park units as part of generating baseline data products for the NPS Natural Resources Inventory and Monitoring Program. Plot data were collected during field visits to SAJH during the summer of 2010 and spring of 2011. Vegetation polygons were initially developed using aerial photography within ArcGIS. These polygons were modified based on field work conducted during the summer of 2010 and spring of 2011. The small extent of the park allowed classification data collection to occur simultaneously with field-based mapping. Prior to conducting field visits, existing vegetation...

Lewis and Clark National Historical Park Vegetation Mapping Project - Spatial Vegetation Data

Alliance-based vegetation map for Lewis and Clark National Historical Park produced by the Institute for Natural Resources at Portland State University. Part of the Vegetation Mapping Program of the Inventory and Monitoring program at NPS. Several imagery sources were used to construct the vegetation map. LiDAR, SPOT 4, NAIP, and LANDSAT were available for the majority of the project area, with only a few places in Washington lacking LiDAR data. The eCognition software package and Berkley Imaging Segmentation was used to create the initial image segments and polygon map used to aid in collection of field training data. The mean values of various variable inputs were summarized by each of the image segments in addition...
