Jest to spójny zbiór danych DEM 3DEP dla Stanów Zjednoczonych, który obejmuje 48 stanów kontynentalnych, Hawaje i terytoria Stanów Zjednoczonych. Usługa jest częściowo dostępna na Alasce i będzie rozszerzana na cały stan w ramach inicjatywy Alaska Mapping Initiative.
Odległość między punktami na ziemi wynosi około 10 metrów w kierunku północ-południe, ale w kierunku wschód-zachód jest zmienna ze względu na zbieżność południków wraz z szerokością geograficzną.
Zbiór danych 1m jest pozyskiwany jako USGS_3DEP_1m.
Jest to bezszwowy zbiór danych 3DEP DEM dla Stanów Zjednoczonych, który obejmuje 48 stanów kontynentalnych, Hawaje i terytoria Stanów Zjednoczonych. Obecnie dostępny jest częściowy zasięg w Alasce, który jest rozszerzany na cały stan w ramach inicjatywy Alaska Mapping Initiative. Odległość od ziemi wynosi około 10 metrów w kierunku północnym/południowym, ale…
