The NWI Program has produced wetland maps for 91% (78% final) of the lower 48 states, all of Hawaii, and 35% of Alaska. Wetlands are classified according to the Service's official wetland classification system (Cowardin et al. 1979). This classification describes wetlands by ecological system (Marine, Estuarine, Lacustrine, Riverine, and Palustrine), by subsystem (e.g., water depth, exposure to tides), class (vegetative life form or substrate type), subclass, water regimes (hydrology), water chemistry (pH and salinity), and special modifiers (e.g., alterations by humans). The maps have been converted to digital data for 47% of the lower 48 states and 18% of Alaska. The availability of digital data and geographic information system (GIS) technology make it possible to use NWI data for various geospatial analyses.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e U S Fish \u0026amp; Wildlife Service\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1507771762\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781507771761\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Createspace Independent Publishing Platform\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/14\/2015\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 32\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.22lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.02h x 8.50w x 0.07d","brand":"U S Fish \u0026 Wildlife Service","offers":[{"title":"Paperback","offer_id":48623027781887,"sku":"9781507771761","price":12.75,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/correlating-enhanced-national-wetlands-inventory-u-s-fish-wildlife-service-9781507771761","provider":"WR Book House","version":"1.0","type":"link"}
