Two GPS-derived classification features are merged with visible image data to create terrain-moisture (TM) classes, defined here as visibly identifiable terrain or landcover classes containing a surface\/soil moisture component. As compared to using surface imagery alone, classification accuracy is significantly improved for a number of visible classes when adding the GPS-based signal features. Since the strength of the reflected GPS signal is proportional to the amount of moisture in the surface, use of these GPS features provides information about the surface that is not obtainable using visible wavelengths alone. Application areas include hydrology, precision agriculture, and wetlands mapping.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Nasa Technical Reports Server (Ntrs)\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1289163812\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781289163815\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/15\/2013\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 24\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.14lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.05d","brand":"Nasa Technical Reports Server (Ntrs)","offers":[{"title":"Paperback","offer_id":48153581977855,"sku":"9781289163815","price":14.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_4f9be8e3-de0b-4a7f-9d19-8ee087265302.jpg?v=1770784455","url":"https:\/\/www.whiterainbookhouse.com\/products\/mars-exploration-rovers-entry-descent-nasa-technical-reports-server-ntrs-9781289163815","provider":"WR Book House","version":"1.0","type":"link"}
