{"product_id":"mi-allegan-geochange-1979-2012-western-michigan-university-map","title":"MI-Allegan GeoChange: 1979-2012","description":"Authoritative GeoChange U.S. Topos(Copyright): The last edition of 7.5 x 7.5 minute paper\r\ntopographic maps of the USGS have been hyper-accurately imaged, processed,\r\ngeoreferenced, and colorized. These topos have been draped onto NAIP aerial images\r\n(accurate to ca. 5 m).  Because of high quality USGS cartography, and because\r\nof The W.E. Upjohn Center's thorough accuracy control, these maps may often\r\nbe used to a 1:6,000 scale (1 in = 500 ft). Where no map content exists, users can see the NAIP aerial image displayed with no overlay.  Where map content exists, users can see the the topo and the NAIP, both semi-\r\ntransparently.  You can assess geographic change by comparing the foreground\r\nmap with the background image in this hybrid map.  The background complements\r\nthe foreground for ease of user interpretation, and vice versa.","brand":"Western Michigan University","offers":[{"title":"Default Title","offer_id":36438286237852,"sku":"68023","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0441\/7850\/5884\/files\/western-michigan-university-mi-allegan-geochange-1979-2012-digital-map-35487634718876.jpg?v=1690799709","url":"https:\/\/store.avenza.com\/products\/mi-allegan-geochange-1979-2012-western-michigan-university-map","provider":"Avenza Maps","version":"1.0","type":"link"}
