<p> <strong>Definition</strong></p><p> Structured errors are a concept introduced to characterise certain errors in satellite imagery. Structured errors arise from effects that influence more than one measured value in the image, but are not in common across the whole image. The originating effect may be random (aleatoric) or systematic (but acting on a subset or locality of pixels), but in either case the resulting errors are not independent, and may even be perfectly correlated across the affected pixels.</p><p> <strong>Source</strong></p><p> <span style="font-size: 8pt;">FIDUCEO vocabulary</span></p><p> <strong>Suggestions</strong></p><p><span class="diff-html-added" previous="first-diff" changeId="added-diff-0" next="last-diff"> </span><span class="diff-html-added" id="added-diff-0" previous="first-diff" changeId="added-diff-0" next="last-diff"> </span></p><p><span class="diff-html-added" previous="first-diff" changeId="added-diff-0" next="last-diff"> </span><strong style="font-size: 8pt;"><span class="diff-html-added" previous="first-diff" changeId="added-diff-0" next="last-diff">Category</span></strong><span class="diff-html-added" previous="first-diff" changeId="added-diff-0" next="last-diff"><!----></span></p><p><span class="diff-html-added" previous="first-diff" changeId="added-diff-0" next="last-diff"> </span><a href="https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fcalvalportal.ceos.org%2Ft-d_wiki%3Fp_p_id%3D54_INSTANCE_Wg3ti1194i20%26p_p_lifecycle%3D0%26p_p_state%3Dnormal%26p_p_mode%3Dview%26p_p_col_id%3Dcolumn-2%26p_p_col_count%3D1%26_54_INSTANCE_Wg3ti1194i20_struts_action%3D%252Fwiki_display%252Fview%26_54_INSTANCE_Wg3ti1194i20_nodeName%3DCEOS_Terms_and_Definitions%26_54_INSTANCE_Wg3ti1194i20_title%3D2.%2BMeasurement%2Band%2BMetrology%2Bwords&amp;data=04%7C01%7Cfaye.lai%40npl.co.uk%7C71d207afa14d469389d808d988e92c16%7C601e5460b1bf49c0bd2de76ffc186a8d%7C1%7C0%7C637691357310852893%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=6Z7RKKAjDIIw%2Bbkm%2ByC1Y59lUo%2FBNQDiM6JtmtGQLes%3D&amp;reserved=0"><span class="diff-html-added" previous="first-diff" changeId="added-diff-0" next="last-diff">2.
