Name: Nowitna WSR - River

Display Field: WSR_Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This feature class depicts the line of ordinary high water on the left and right banks of Nowitna WSR. The polygons contained in this feature class were digitized from high-resolution (submeter) satellite imagery as published in the World Imagery image service by ESRI. This image service is available at the following URL:http://services.arcgisonline.com/arcgis/rest/services/World_Imagery/MapServerThe ordinary high water line of the left and right banks were digitized onscreen while zoomed in to a scale of 1:3,000. Digitizing was performed by Scott McGee, Cartographer, USFWS Alaska Region Division of Realty.This feature class is Step 1 of 6 in the process that was used to derive the preliminary WSR corridor boundaries. The processing order is outlined below:Step 1: Version 2a - ordinary high water lineStep 2: Version 2b - ordinary high water line with imagery metadata addedStep 3: Version 2c - ordinary high water line buffered with a 0.5 mile wide buffer zone on each side of the riverStep 4: Version 2d - ordinary high water line buffered with a 0.5 mile wide buffer zone on each side of the river with imagery metadata addedStep 5: Version 2e - ordinary high water line buffered with a 0.5 mile wide buffer zone on each side of the river with imagery metadata added and private lands removedStep 6: Version 2f - ordinary high water line buffered with a 0.5 mile wide buffer zone on each side of the river with imagery metadata added and private lands and river removed
