Integration And Delivery Of Interferometric Synthetic Aperture Radar [Insar] Data Into Stormwater Planning Within Karst Terranes, Brian Bruckno, Andrea Vaccari, Edward Hoppe, Scott Acton, Elizabeth Campbell

Department of Earth and Atmospheric Sciences: Faculty Publications

As part of two USDOT-funded studies focused on the development of satellite-based Interferometric Synthetic Aperture Radar (InSAR) technology, the researchers integrated InSAR-derived point cloud data into the transportation design process to optimize the location of a stormwater management system in a karst terrane. After initial validation, the InSAR data (over 1.67 million data points comprising various “scatterers”) were brought into a GIS dataframe and georeferenced to locations of known sinkholes. This dataset was then used to evaluate karst hazard within a 40x40km data frame located in the Valley and Ridge Province of Virginia. The group identified systematic kinematic differences in …

Estimating Medically Fragile Population Exposures To Tropical Storm Surges, James L. Wilson, Eileen Neuffer

International Journal of Geospatial and Environmental Research

Background. A particularly vulnerable sub-population is the medically fragile. The medically fragile (MF) are defined as those who have at least one chronic condition and are electrically and pharmaceutically dependent, including the need for oxygen, and require care within 48 hours. Estimates of MF populations at risk from environmental hazards are important for emergency management planning and mitigation.

Materials and Methods. The MF population is comprised of 8% of the total population under 75 years plus all those 75+ years. Zonal estimates of MF populations are obtained by clipping block level US Census populations with SLOSH basin data (SLOSH Display …

Orogenic Gold Prospectivity Mapping Using Geospatial Data Integration, Region Of Saqez, Nw Of Iran, Alireza Almasi̇, Alireza Jafari̇rad, Peyman Afzal, Mana Rahi̇mi̇

Bulletin of the Mineral Research and Exploration

The aim of this study is to map orogenic gold prospecting areas in the region of Saqez, NW of Iran. In order to achieve this task geological, geochemical and airborne geophysical data are analyzed and integrated using index overlay and fuzzy logic methods. Geological map of Saqez (1:100.000 scale) is used to assign lithological weights based on their favorability for hosting orogenic Au mineralization. Also a fault density map is produced and assigned based on the structural map which is included in the geological map. For preparing geochemical evidence maps, data from 535 stream sediment samples are examined using Number-Size …

Utilizing Remote Sensing Imagery To Monitor Vegetation Change Within World Heritage Sites, Mimi Eve Hatzis

Theses and Dissertations

ABSTRACT

World Heritage sites provide a glimpse into the stories and civilizations of the past. There are currently 1007 unique World Heritage properties with 779 being classified as cultural sites, 197 as natural sites, and 31 falling into the categories of both cultural and natural sites (UNESCO & World Heritage Centre, 1992-2015). However, of these 1007 World Heritage sites, at least 46 are categorized as in danger and this number continues to grow. These unique and irreplaceable sites are exceptional because of their universality. Consequently, since World Heritage sites belong to all the people of the world and provide inspiration …

Ranking Trails Based On Natural Hazards Instead Of Difficulty: A Case Study On Starved Rock State Park, Julia Ryherd

Honors Program Projects

Starved Rock State Park in North-Central Illinois is not topographically flat as are many glaciated areas of Illinois. Its deep canyons and steep valley walls provide the backdrop for a diverse variety of natural hazards. Geologic hazards include steep canyon walls, flooding with erosion events, high elevation vantage points, and rock falls. Other natural hazards include falling tree branches and steep staircases. ArcGIS was used to record locations of both hazards and injuries along the trails and feature classes were made for each hazard. These feature classes were spatially joined and a weighted sum computed to create a hazard rating …
