Collect audio. Download, store, and prepare audio. Pre-process audio - Resample audio, Split raw recordings into 2.5 s clips, Convert waveforms to spectrogram images, Mel transform spectrograms. Build model. Train model. Inference.

The 3D National Topography Model (3DNTM) is a vision for an integrated 3D model of elevation and hydrography data that will support environmental, geologic, and infrastructure applications. It responds to changing U.S. policy and will support Federal, State, local, and other stakeholder needs.

Background: USGS Photo of Porkchop Geyer in Yellowstone. Foreground: A cartoon turkey wearing an astronaut helmet looks sheepishly at Porkchop Geyser erupting nearby. Cartoon images of common Thanksgiving side dishes are also placed around the turkey (in this case, a gravy boat and an ear of corn).

This map of the United States and its territories shows geographic extent of the first-ever nationally consistent hydrography data acquired from high-resolution 3D Elevation Program (3DEP) data. FY23 projects are the result of ongoing Federal coordination via the 3DHP Working Group and the Alaska Mapping Initiative.
