Because bottom substrate composition is an important control on the temporal and spatial location of the aquatic community, accurate maps of benthic habitats of inland lakes and reservoirs provide valuable information to managers, recreational users, and scientists. Therefore, we collected vertical, split-beam sonar data (roughness [E1], hardness [E2], and bathymetry) and sediment samples to ma...

[1] We present a new map of Titan’s surface obtained in the spectral ‘window’ at 1.6 mm between strong methane absorption. This pre-Cassini view of Titan’s surface was created from images obtained using adaptive optics on the W.M. Keck II telescope and is the highest resolution map yet made of Titan’s surface. Numerous surface features down to the limits of the spatial resolution ( 200–300 km) ...

We present a new approach for remote exploration by autonomous surface robots. In our method the agent synthesizes in situ measurements with remote sensing data to learn a multi-scale model of the explored environment. This intelligent map predicts the information value of candidate observations to guide adaptive navigation and sampling decisions. The agent learns map parameters on the fly, mod...

Introduction: The Galilean satellites represent a series of bodies that all formed from the same proto-Jovian nebula but are distinctly different in their physical properties, surface geology, and thermal evolution [1-4]. The explanation for many of these disparate characteristics is likely related to the radially varying conditions of the nebula during the earliest period of their formation [5...

Research in map generalization starts to focus on other types of maps than on topographic maps only. Therefore, new generalization concepts have to be developed, extending on the experiences and research efforts originally made in topographic generalization. This paper presents a new conceptual framework of map generalization with respect to thematic mapping based on an analysis of the literatu...

The relative potential for elevated residential indoor radon has been mapped for the City of Fort Collins, Colorado. Using published geologic maps and soil permeability information, the study area was divided into geologic and soil permeability (geoperm) units. Evaluation of the data showed a relationship between residential basement indoor radon concentrations and geopenn units. Mean indoor ra...

logic map of Northeast Gale crater. Solid and patterned shapes represent unique geologic units identified through morphological classifications using HiRISE and CTX. Blue and green outlines indicate identification of mafic and hydrated mineral phases found through the use of CRISM. STRATIGRAPHY OF THE GALE CRATER RIM AND FLOOR UNITS. J. Buz 1 and B. L.

In geologic imaging spectroscopy studies, typical end products are often mineral maps. These maps are usually ambiguous and form a limited method of representing geological information that is potentially contained in spectroscopic images. This situation can be improved by mapping the spatial configuration of the effects of geological processes instead of the solely individual minerals in a non...
