U.S. Counties represents the counties of the United States in the 50 states, the District of Columbia, and Puerto Rico.
This shapefile approximates the area less than 20 km offshore of the North Pacific Coastline as defined by the "World Country Boundaries (Generalized)" shapefile distributed by ESRI as part of their Data & Maps data series.
High-resolution river centerlines vector shapefiles has 50 large rivers across the world. This high-resolution layer was generated will enable researchers to identify accurate river length, from headwaters to delta. The polylines could be used in coordination with any satellite-derived environmental or landscape variables for ecological research.

This point shapefile approximates locations within 20 km of the North Pacific Coastline, as defined by the "World Country Boundaries (Generalized)" shapefile distributed by ESRI as part of their Data & Maps data series. They are based on raster data at 4 km resolution. Therefore there are between 3-5 points extending out from each location along the shoreline (at 4 km intervals).
