Improving geospatial knowledge - Professors launch DelawareView to improve public access to remote sensing and geospatial data

Date

Faculty members in the University of Delaware’s Department of Geography have launched the DelawareView (DEView) consortium to improve public access to remote sensing and geospatial data.

DEView is an affiliate member of AmericaView, a national network of remote sensing scientists and GIS scientists, funded by the U.S. Geological Survey, who support the use of Landsat and other public domain remotely sensed satellite data for research, education and technology transfer.

DGS releases new DGIR web application

Date

The Delaware Geological Survey has released the Delaware Geologic Information Resource (DGIR), an online data display tool and map viewer for geologic and hydrologic information, as a "beta" site. DGIR was designed to provide the Delaware professional community with a variety of geoscience data in one application. DGS will continue to refine the both the data and functionality of the website as it is reviewed.

Delaware Geologic Information Resource (DGIR) Map Viewer

Project Contact(s)

The Delaware Geologic Information Resource (DGIR) is an online data display tool and map viewer for a variety of geologic and hydrologic information released by the Delaware Geological Survey. It was designed to deliver the most commonly available and requested geologic and hydrologic information that is appropriate for use in hydrologic studies, required by regulation and ordinance, and to support state resource management decisions.

Use of Geospatial Data in Planning for Offshore Wind Development

Date

Four UD faculty and staff and a graduate student wrote a chapter in the book Geospatial Techniques for Managing Environmental Resources. The chapter is titled "Use of Geospatial Data in Planning for Offshore Wind Development," and the authors are John Madsen, associate professor, Department of Geological Sciences; Alison Bates, master's degree student, School of Marine Science and Policy; John Callahan, research scientist, Delaware Geological Survey; and Jeremy Firestone, professor, School of Marine Science and Policy, all in the College of Earth, Ocean, and Environment.

Publishing Surficial Geologic Maps of Delaware

Date

Lillian T. Wang, GIS specialist/cartographer, Delaware Geological Survey, made a presentation titled "Publishing Surficial Geologic Maps of Delaware" at Digital Mapping Techniques 2011, College of William and Mary, Williamsburg, Va., May 24.

IS1 Delaware Geological Survey Cartographic Information Center

The Delaware Geological Survey Cartographic Information Center has made the DGS a focal point for questions concerning the availability of all types of aerial photography, thematic maps, planimetric maps, topographic maps, historic maps, LANDSAT imagery, space imagery, side looking aerial radar imagery (SLAR), and geodetic control. Sources of maps, charts, aerial photography, boundary mark information, and vertical geodetic control can be obtained for your area of interest within the State through the Center's computer-searchable data bases.

DGS unveils new website

Date

The Delaware Geological Survey has unveiled a new version of their public web site. Although many of the technologies employed are consistent with modern web standards, giving the user a familiar feel and comfort level, particular attention has been paid to information and the retrieval of it.

Web-Delivered Application for Hydrogeologic Data

Project Contact(s)

This project is designed to deliver, by web-based technologies, the most commonly available and requested geologic and hydrologic information used in hydrologic studies required by regulation and ordinance and used by state agencies to support resource-management decisions. Available information can be associated with points or areas. Information associated with points includes descriptive logs, geophysical logs, raw and interpreted groundwater levels, aquifer and geologic unit identification, and hydraulic characteristics of wells. Information associated with areas is either in the form of raster-based (grid) data or polygons. Examples of raster-based data include water-table depths and elevations, tops and thicknesses of geologic and aquifer units, and aquifer transmissivity. Examples of polygons include surficial geology and groundwater recharge potential.

The intent of developing a web-technology enabled system is to provide a more intuitive and comprehensive toolset for locating, quickly viewing, and downloading the desired information in an efficient, extensible, and familiar manner.

Presentation on national LiDAR applications and benefits

Date
