Geologic Map of Aphrodite Map Area (AMA; I‐2476), Venus [PDF]

open access: yesEarth and Space Science, 2020
We present a 1:10‐M‐scale geologic map of the Aphrodite Map Area (AMA) of Venus (0°N–57°S/60–80°E). Geologic mapping employed NASA Magellan synthetic aperture radar and altimetry data.

Geologic Map of the Niobe Planitia Region (I‐2467), Venus [PDF]

open access: yesEarth and Space Science, 2020
We present a 1:10M scale geologic map of the Niobe Planitia region of Venus (0°N–57°N/60°E–180°E). We herein refer to this area as the Niobe Map Area (NMA). Geologic mapping employed NASA Magellan synthetic aperture radar and altimetry data.

Statewide surficial geologic map of Nebraska underscores Quaternary landscape evolution from the High Plains to the Central Lowland

open access: greenJournal of Maps
Surficial geologic mapping in Nebraska has been conducted primarily at the 1:24,000 scale since the mid-1990s, although there have also been limited efforts to map generalized Quaternary and surficial geology within the state and the region.

Entropic Regularization to Assist a Geologist in Producing a Geologic Map

open access: yesEntropy, 2011
The gravity and magnetic data measured on the Earth’s surface or above it (collected from an aircraft flying at low altitude) can be used to assist in geologic mapping by estimating the spatial density and magnetization distributions, respectively ...

Non-affine georectification to improve the topographic fidelity of legacy geologic maps

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
Field-based geologic maps, which are among the most valuable tools of communication among geoscientists, can be expensive and time-consuming to produce or manually revise.

A geology-constrained new intelligence method of synthesizing geologic bodies

open access: yesDizhi lixue xuebao, 2021
Due to its massive content, complex processing logic and heavy repeated workload, geologic body synthesis, as the key task in the geological map compilation, is the primary factor affecting the process.

Effect of Spatial and Spectral Scaling on Joint Characterization of the Spectral Mixture Residual: Comparative Analysis of AVIRIS and WorldView-3 SWIR for Geologic Mapping in Anza-Borrego Desert State Park

open access: yesSensors, 2023
A geologic map is both a visual depiction of the lithologies and structures occurring at the Earth’s surface and a representation of a conceptual model for the geologic history in a region.
