Imagery, sediment collection, photogrammetry, and meteorological data from July 2023 to November 2024, Grand Falls Dune Field, Arizona Imagery, sediment collection, photogrammetry, and meteorological data from July 2023 to November 2024, Grand Falls Dune Field, Arizona

Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This active dune field displays a range of morphologies, including barchans, dome dunes, smaller dunes, and ripples, and is bimodal both in mineralogical composition and grain size distribution. The felsic component is likely derived from the Little Colorado River, and the mafic component (basaltic...

Profiles and properties of Martian gully flows from HiRISE DTMs and orthoimages, 2006-2020 Profiles and properties of Martian gully flows from HiRISE DTMs and orthoimages, 2006-2020

This dataset contains shapefiles that describe topographic long profiles of recent Martian gully flows recording various information about the flow and host gully. Each profile has some or all of the following: a profile of the active flow, a profile of the full gully, the location of the channel mouth, a profile recording different types of activity, a shapefile with locations of...

Mars Sample Return HiRISE Mosaics for Terrain Relative Navigation Mars Sample Return HiRISE Mosaics for Terrain Relative Navigation

In order to support the landing and operations of NASA Mars 2020 Perseverance rover, the U.S. Geological Survey (USGS) previously generated Digital Elevation Model (DEM) and orthoimage mosaics of the floor of Jezero crater. Over four years of operations, Perseverance has collected numerous samples while climbing the western rim of Jezero and has travelled beyond the extent of the...

Metadata on this main landing page applies to all DTMs listed under Child Items, apart from USGS-made DTMs [HRSC DTM_75 (centered at -28.8N, 78.6E)_USGS and CTM DTM over "Crater L" (centered at -23.1N, 74.3E)_USGS]. Metadata associated with USGS-made DTMs are located with DTM files under their respective Child Item.

Lunar Grid Reference System (LGRS) Terrestrial Navigational Training Grids in Artemis Condensed Coordinate (ACC) Format Lunar Grid Reference System (LGRS) Terrestrial Navigational Training Grids in Artemis Condensed Coordinate (ACC) Format

USGS is assessing the feasibility of map projections and grid systems for lunar surface operations. We propose developing a new Lunar Transverse Mercator (LTM), the Lunar Polar Stereographic (LPS), and the Lunar Grid Reference Systems (LGRS). We have also designed additional grids to meet NASA requirements for astronaut navigation, referred to as LGRS in Artemis Condensed Coordinates...
