This dataset depicts vegetation and land cover for Klamath Marsh NWR. It was created using eCognition software and multiple sources of imagery. Field data were also collected at two different time to assist with image interpretation/classification. Details: This dataset was created by interpreting and classifying multiple image sources. These include: July 2005 2.5 meter Quickbird multispectral imagery, July 2005 ASTER 15 meter multispectral imagery, July 2006 Landsat 30 meter multispectral imagery, and December 2005 ASTER 15 meter multispectral imagery. Images were loaded into eCognition software which created polygons based on areas with similar image features. Statistics were then created for each polygon based...

Vegetation and land cover data for Upper Klamath NWR. This dataset is based on interpretation of 2014 near-infrared imagery produced by the National Aerial Imagery Program of the U.S. Department of Agriculture with input on the general vegetation composition provided by local refuge staff. Field data at the species level were not available and further work is needed to refine this product to meet the convention of the National Vegetation Classification System. In addition, no validation was performed on this dataset.

This layer represents land cover classes mapped within the Modoc Wildlife Refuge. Mapping was completed using a combination of field data, object-based image analysis using Feature Analyst, and photo interpretation. Source data included 2005 CIR NAIP digital aerial photography, and Modoc National Wildlife Refuge data layers. Field data was collected by USFWS staff in May and June of 2007.

This dataset contains vegetation and land cover information for Antioch Dunes National Wildlife Refuge. It was created by visual interpretation and classification of aerial photography (National Agriculture Imagery Program) acquired in August 2014. Specifically, the NAIP imagery was segmented into polygons using eCognition Developer 9.0 software. Each segment was then classified by visually interpreting the aerial imagery. The interpretation process was facilitated by field data and geotagged field photos that were taken on the property in October 2014. No accuracy assessment was performed due to a limitation in the number of available ground control points.

This dataset depicts vegetation and landcover at a broad scale for Tule Lake National Wildlife Refuge. It was created through interpretation of aerial imagery (NAIP orthophotography) acquired in August 2014 by the USDA. Ecognition software was then used to create segments of the imagery and those segments were manually classified by a GIS Analyst with the help of refuge biologists and staff with expert knowledge of the local conditions. The GIS Analyst also made a reconnaissance trip to the area in the fall of 2014 to assist with image interpretation. No systematically collected field data were available to create a classification at a finer level, such as the Alliance or Associate level and so this product does...

A GIS-based analysis was used to model habitat connectivity in the three Okanagan Regional Districts in British Columbia: the North Okanagan Regional District, the Central Okanagan Regional District and the Regional District of Okanagan-Similkameen. This model integrated a series of parameters to identify connected and potentially fragmented habitats. The model was not specific to a particular species. The goal was to identify portions of the landscape offering a higher opportunity for wildlife movement at a regional scale. The following parameters were used to model connectivity corridors: Elevation – Lower elevations (i.e., the valley) receive higher scores; Slope – Steep slopes receive lower scores; Terrain Ruggedness...

This dataset depicts land cover and vegetation for San Joaquin River NWR. It uses the most current version of CalVeg from the U.S. Forest Service and is clipped to the refuge boundary. This Existing Vegetation (Eveg) polygon feature class is a CALVEG (Classification and Assessment with LANDSAT of Visible Ecological Groupings) map product from a scale of 1:24,000 to 1:100,000 for CALVEG Zone 6, the Central Coast . Source imagery for this layer ranges from 1997 - 2013. The CALVEG classification system was used for vegetation typing and crosswalked to other classification systems in this database. USGS Land Use / Land Cover Anderson 1 classification system is included in the database to meet national standard...
