This collection of 22 articles, half new and half previously published in peer-reviewed journals, assembles the latest thinking on the use of two advanced services-CORS and OPUS-for obtaining accurate positional coordinates. Created and managed under the auspices of the National Geodetic Survey, the CORS (continuously operating reference stations) network contains more than 1,600 permanent, geodetic-quality receivers that collect GPS data around the clock at locations distributed throughout the United States, its territories, and a few foreign countries. These data are then made freely available to the public via the Internet. OPUS (online positioning user service) is a free, automated, Web-based utility that provides its users with accurate and reliable positional coordinates in a timely fashion by processing each user's GPS data with corresponding data from the CORS network. Together, CORS and OPUS form the backbone of today's high-accuracy, three-dimensional positioning activities.\u003c\/p\u003e\u003cp\u003eBoth theoretical and empirical, this collection is a must-have for practitioners and researchers involved in surveying, GIS, remote sensing, and mapping applications that utilize GPS technology.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"American Society of Civil Engineers","offers":[{"title":"Default Title","offer_id":47030310600944,"sku":"9780784411643","price":90.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780784411643_p0.jpg?v=1763659306","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780784411643","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
