Remote sensing, especially Landsat, enables practical shoreline delineation over varying spatial and temporal scales, but validation is needed because high-resolution surveys like aerial photography and LiDAR are costly and capture only instantaneous shoreline positions. Spectral water indices such as AWEI and MNDWI are compared for water extraction accuracy, while satellite-derived shorelines are commonly validated against high-resolution imagery and, in some studies, reference data is omitted.","cbCailGAKOX91kqC","https://ap.wps.com/l/cbCailGAKOX91kqC","pdf",3457799,15,1,13,"English","en","",1776566298,33,{"code":4,"msg":28,"data":29},"ok",{"site_id":30,"language":23,"slug":31,"title":13,"keywords":24,"description":14,"schema_data":32,"social_meta":67,"head_meta":70,"extra_data":72,"updated_unix":25},105,"using-gps-surveyed-intertidal-zones-to-determine-the-validity-of-satellite-derived-shorelines",{"@graph":33,"@context":66},[34,51],{"@type":35,"itemListElement":36},"BreadcrumbList",[37,41,45,48],{"item":38,"name":39,"@type":40,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":42,"name":43,"@type":40,"position":44},"https://docshare.wps.com/document/","Document",2,{"item":46,"name":12,"@type":40,"position":47},"https://docshare.wps.com/document/research-report/",3,{"item":49,"name":13,"@type":40,"position":50},"https://docshare.wps.com/document/using-gps-surveyed-intertidal-zones-to-determine-the-validity-of-satellite-derived-shorelines/16534/",4,{"url":49,"name":13,"@type":52,"author":53,"headline":13,"publisher":55,"fileFormat":58,"description":14,"dateModified":59,"datePublished":60,"encodingFormat":58,"isAccessibleForFree":61,"interactionStatistic":62},"DigitalDocument",{"name":9,"@type":54},"Person",{"url":38,"name":56,"@type":57},"DocShare","Organization","application/pdf","2026-06-05","2026-04-19",true,{"@type":63,"interactionType":64,"userInteractionCount":19},"InteractionCounter",{"@type":65},"ViewAction","https://schema.org",{"og:url":68,"og:type":69,"og:title":13,"og:site_name":56,"og:description":14},"https://docshare.wps.com/document/using-gps-surveyed-intertidal-zones-to-determine-the-validity-of-satellite-derived-shorelines/16534","article",{"robots":71,"canonical":68},"index,follow",{"doc_id":7,"site_id":30}]
