Introduction: The geologic features “shield fields” and “shield plains” (or “shield terrain”) have been used by a number of Venus researchers and authors of Venus geologic quadrangle maps. However, there has been occasional confusion concerning the two terms and the geologic units they define. Stratigraphic interpretation may vary due to the identification of clusters of small shields as either...

Developing accurate stream maps requires both an improved understanding of the drivers streamflow spatial patterns and field verification. This study examined locations in three semiarid catchments across elevation gradient Colorado Front Range, USA. The surface flow throughout each channel network were mapped used to compute active drainage densities. Field surveys compared National Hydrograph...

the proposal of geomorphologic matters in relation to tourism is one of interdisciplinary research approaches that has been considered in recent years. in this manner, geomorphological sites are defined as geomorphological landforms and processes that have acquired a scenic/aesthetic, scientific, cultural/historical and/or a social/economic value due to human perception of geological, geomorpho...

This work presents a method to automate simple aspects of geologic image analysis during space exploration. Automated image analysis onboard the spacecraft can make operations more efficient by generating compressed maps of long traverses for summary downlink. It can also enable immediate automatic responses to science targets of opportunity, improving the quality of targeted measurements colle...

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...

Detailed information about geology, hydrogeology and seismic hazard issues for Umbria region are contained in a spatial database available as open data format (shapefile or KMZ) and distributed under the regional open data portal called Open Data Umbria ( http://dati.umbria.it ) where 297 datasets have been produced by Umbria Region until now and most of them are made by Geological Survey. Geol...

Interpolated contour maps drawn for aluminum, copper and molybdenum in downstream monitoring boreholes of water dam in Miduk Copper Complex and the values of pH, redox potential (Eh) and distance from water dam indicate different trends of variation and behavior of these three elements in downward groundwater resources. As these maps exhibit, aluminum is dominant in the most alkaline (pH = 9-11...
