זהו מערך נתוני ה-DEM של 3DEP בארה"ב, עם כיסוי מלא של 48 המדינות הרציפות, הוואי והטריטוריות של ארה"ב. כיסוי באלסקה זמין עכשיו באופן חלקי, והוא מתרחב לכיסוי בכל רחבי המדינה כחלק מיוזמת המיפוי של אלסקה.
המרווח בין הקווים בקרקע הוא בערך 10 מטרים מצפון לדרום, אבל משתנה ממזרח למערב בגלל ההתכנסות של קווי האורך עם קווי הרוחב.
