<div><div style='margin-bottom:3rem;'><div style='max-width:100%; display:inherit;'>The <b>Enhanced Contrast Map (US Edition) </b>web map provides a detailed vector basemap for the world symbolized using enhanced contrast and a color-vision-deficient-safe palette. It is designed for use as part of a presentation that aims to meet the <a href='https://www.w3.org/WAI/standards-guidelines/wcag/' target='_blank' rel='nofollow ugc noopener noreferrer'>WCAG</a> (Web Content Accessibility Guidelines) AA standard, and US Government <a href='https://www.section508.gov/' target='_blank' rel='nofollow ugc noopener noreferrer'>Section 508</a> compliance. </div><div style='overflow:auto; padding-bottom:0.375rem; max-width:100%; display:inherit;'><br /></div><div style='overflow:auto; padding-bottom:0.375rem; max-width:100%; display:inherit;'>The base layer includes highways, major roads, minor roads, railways, water features, cities, parks, landmarks, and building footprints. The reference layer includes all labels and administrative boundary lines. Label size has been increased where possible, but not to the point where it conceals the map detail. The 'Ubuntu' font is used throughout, to be clear and legible while maintaining some character.</div><div style='overflow:auto; padding-bottom:0.375rem; max-width:100%; display:inherit;'><div><br /></div><div>This basemap is available in the <a href='https://www.arcgis.com/home/group.html?id=68efc5ce1e0b43cb819f7bba4a6bd7ea' target='_blank' rel='nofollow ugc noopener noreferrer'>United States Vector Basemaps</a> gallery and uses the <a href='https://www.arcgis.com/home/item.html?id=34151764a54741209a7d57957ba54c74' target='_blank' rel='nofollow ugc noopener noreferrer'>Enhanced Contrast Reference (US Edition)</a> and <a href='https://www.arcgis.com/home/item.html?id=d6e5bfbe9e0b4ad0bd200262bef745b0' target='_blank' rel='nofollow ugc noopener noreferrer'>Enhanced Contrast Base</a> vector tile layers.</div><div><br /></div><div><div>The vector tile layers in this web map are built using the same data sources used for other Esri Vector Basemaps.

If you would like to add this map as a layer in other maps you are creating, you may use the tile layers referenced in this map.</div></div></div></div></div></div><div style='margin-bottom:3rem; font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'></div><div style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'></div><div style='margin-bottom:3rem; display:inherit; font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'><div style='margin-bottom:3rem; display:inherit;'></div></div>
