  1. Title: Abundance Estimates of the Pacific Salmon Conservation Assessment Database, 1978-2008

    Contributors:

    Summary: This dataset is a visualization of abundance estimates for six species of Pacific salmon (Oncorhynchus spp.): Chinook, Chum, Pink, Steelhead, Sockeye, and Coho in catchment areas of the Northern Pacific Ocean, including Canada, China, Japan, Russia, and the United States. Catchment polygons included in this layer range in dates from 1978 to 2008. Sources dating from 1950 to 2005, including published literature and agency reports were consulted in order to create these data. In addition to abundance estimates, the PCSA database includes information on distribution, diversity, run-timings, land cover/land-use, dams, hatcheries, data sources, drainages, and administrative categories and provides a consistent format for comparing watersheds across the range of wild Pacific salmon.The Conservation Science team at the Wild Salmon Center has created a geographic database, the Pacific Salmon Conservation Assessment (PSCA) that covers the whole range of wild Pacific Salmon. By providing estimations of salmon abundance and diversity, these data can provide opportunities to conduct range-wide analysis for conservation planning, prioritizing, and assessments. The primary goal in developing the PSCA database is to guide proactive international salmon conservation.

    Contributors:

    Summary: This data represents public land survey systems (PLSS) corners for Dane County, Wisconsin in 2024.

More information about the Statewide Parcel Map Initiative can be found here.The E8 database contains a collection of all uniquely identifiable local-level PLSS data available in digital format, and aggregates that data into a standardized schema and format. It also includes section, quarter-section, and quarter-quarter-section level polygons. The construction of the PLSS corner locations contained within the database relies on the local level coordinate information. This unique aspect of the database, allows for an accurate representation of the on-the-ground location of the PLSS corners.Please complete the feedback survey form.Schema documentation can be found here.]
