The waters of the modern Illinois River flow gently through looping meanders bordered by quiet backwater lakes and drop only a few inches in each river mile. Concealed beneath this gentle river is geologic evidence that the Illinois descended from ancient rivers with surprising and sometimes violent histories. The geologic story of the Illinois River is not only an account of an interesting cha...

INTRODUCTION This paper was prepared for the National Association of Geoscience Teachers Far Western Section Fall Conference, High Sierra Institute, Baker Station, Sierra Nevada September 7 9, 2012. The maps and map interpretations in this document (Figures 1, 2, 3, 4, 5) form about a fourth of a much larger map and manuscript that have been peer reviewed by David John of the U.S. Geological Su...

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 Therefore, new generalization concepts have to be developed, extending on the experiences and research efforts originally made in topographic generalization.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...

This paper introduces the results of integration of lexical and terminological resources, most of them developed within the Human Language Technology (HLT) Group at the University of Belgrade, with the Geological information system of Serbia (GeolISS) developed at the Faculty of Mining and Geology and funded by the Ministry of the Environmental protection. The approach to GeolISS development, w...

This paper describes a prototype system for registering geologic data sets through ontologies to assist in integrating and querying heterogeneous geologic data sets. The system consists of three components: an ontology repository, the data set registration, and ontology-aware applications. User-defined ontologies in OWL are saved and used by the system. Each data set must be registered before i...

EXECUTIVE SUMMARY The impact that the proposed Campo landfill will have on the hydrology of the Tierra del Sol watershed is examined using an interdisciplinary perspective. Analysis of precipitation and well data suggests the presence of an effective hydraulic connection between surface water and groundwater in the region. Existing fracture maps and other geologic evidence reveal the extent

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...

Oppia Quadrangle Av-10 (288–360 E, ±22 ) is a junction of key geologic features that preserve a rough history of Asteroid (4) Vesta and serves as a case study of using geologic mapping to define a relative geologic timescale. Clear filter images, stereo-derived topography, slope maps, and multispectral color-ratio images from the Framing Camera on NASA’s Dawn spacecraft served as basemaps to cr...

In a vast semiarid region of the Baja California Peninsula, remote sensing and GIS techniques were applied to moderate resolution images of Landsat 5 TM to explore the geospatial correlation among the grid aridity index (AI), shapefiles of geologic strata, land use, and geological fractures. A dataset of randomized sample points in a time-series of one hydrologic year along with vector file GIS...
