Instead of working directly with raw spectral bands, embeddings summarize complex patterns\u2014such as texture, shape, and spatial relationships\u2014into compact vectors.<\/p>\n<p data-start=\"1033\" data-end=\"1049\">In simple terms:<\/p>\n<ul data-start=\"1050\" data-end=\"1164\">\n<li data-section-id=\"urli26\" data-start=\"1050\" data-end=\"1106\">Traditional remote sensing \u2192 works with pixel values<\/li>\n<li data-section-id=\"1whoek4\" data-start=\"1107\" data-end=\"1164\">Embeddings \u2192 work with \u201clearned features\u201d from images<\/li>\n<\/ul>\n<p data-start=\"1166\" data-end=\"1327\">These features capture more abstract information, making them powerful for tasks like classification and pattern recognition (Zhu et al., 2017; Ma et al., 2019).<\/p>\n<hr data-start=\"1329\" data-end=\"1332\" \/>\n<h2 data-section-id=\"zo0r7y\" data-start=\"1334\" data-end=\"1376\">How Does This Relate to Remote Sensing?<\/h2>\n<p data-start=\"1380\" data-end=\"1534\">In traditional workflows, analysts rely on multispectral bands from satellites like Landsat or Sentinel.
