Use Of Geospatial Information And Remote Sensing Data To Support Improved Roadway Access Management, Reginald R. Souleyrette, P. E. Plazak, D. J. Plazak

Reginald R. Souleyrette

Urban and suburban roadways serve two distinct and sometimes conflicting purposes: providing mobility and allowing access to land and land developments. High-level urban roadways (e.g. arterials) should primarily serve mobility needs of travellers and goods. Low level, local roadways should primarily allow for land development access. Arterials that allow too much direct land access fail to function properly in terms of both traffic operations and safety. Such roadways are in need of access management. The operational and safety benefits of access management are impressive; access management has been shown to reduce crash rates on urban and suburban arterials by up …

Development Of A Traffic Sign Inventory System (Sign Click), Eric R. Green

Kentucky Transportation Center Research Report

A system is not currently in place to inventory traffic signs in Kentucky. A sign inventory database would be beneficial for those responsible for maintenance and management of signs. The overall safety provided the driving public could benefit from an efficient inventory system that increases an agency’s knowledge of existing signs. In addition, a comprehensive inventory and mechanisms for updating the inventory could reduce the potential for liability associated with outdated, inappropriately placed, or missing signs. Software is available for this kind of inventory; however it can be expensive and would lack the specific features that could be developed in-house. …

Predicting Impacts Of Fuel Reduction For Asset Protection On Threatened Species, R. J. Whelan, L. Collins, R. Loemker

Faculty of Science - Papers (Archive)

Fuel reduction in bushland adjacent to urban development is an important component of bushfire management to protect lives and properties. In many urban areas, the objective of property protection by fuel reduction conflicts with biodiversity management objectives. Conserving threatened species in such situations will require information on spatial distributions of these species in the landscape. We used GIS modelling to predict the likely impacts of strategic fire advantage zones (SFAZs) on two threatened species in the Shoalhaven region of NSW: the eastern bristlebird and the glossy black cockatoo. We used current knowledge of the association between these animals and vegetation …

Distribution And Habitat Characterization Of The Florida Burrowing Owl In Non-Urban Areas, Mark S. Mueller

USF Tampa Graduate Theses and Dissertations

The full geographic distribution and habitat use of the Florida Burrowing Owl, a state "Species of Special Concern," is not well-understood, particularly in remote, non-urban areas. This thesis aimed to expand and improve knowledge about non-urban burrowing owls. We first compiled databases of historic sighting observations. Fieldwork verified and updated existing breeding observation point records and also yielded new breeding locations. Using a GIS, we characterized observed land use, landcover, relevant soil attributes, projected future land use and managed area status for selected points. We quantified landcover within biologically-determined buffer distances around burrows from our own field-verified records. Using standard …

Precipitation Variability Of Streamflow Fraction In West Central Florida, Michael H. Scott

USF Tampa Graduate Theses and Dissertations

There is a strong interest to develop a method to estimate mean annual ungaged streamflow with varying precipitation. A method was developed utilizing GIS and other statistical analysis to estimate ungaged mean annual streamflow. This method utilizes a normalized streamflow fraction (NSF) method previously developed which relies on drainage basin area, coupled with mean annual local precipitation, to estimate the ungaged streamflow variability. This method has been applied to west central Florida.The test of the method yielded an R squared value of 0.9894, proceeded by a verification that yielded an R squared value of 0.998. This method is believed to …

Gis Analysis Of The Caves And Karst Of The Mariana Islands, Kevin Michael Toepke

Theses and Dissertations

The Mariana Islands are a volcanic island chain in the western Pacific Ocean composed of Eocene volcanic cores with a carbonate mantle. Others have classified the cave and karst features into the cave types described in the CIKM, but no comprehensive GIS has been developed. For this project, a comprehensive GIS of the cave and karst features was developed. The cave and karst features were divided by cave type, physiographic province, and island. The karst features in the GIS were hyperlinked to a series of HTML pages, one for each island, and a set of HTML navigation pages mirroring the …

Dissolution Caves Of Mississippi, Christopher Michael Moore

Theses and Dissertations

The purpose of this project was to distinguish between the karst and pseudokarst caves throughout Mississippi, create an inventory and survey of representative caves and karst features, identify the geology of the rocks hosting the caves, and produce a GIS-based digital karst map. The State of Mississippi is not known for its karst features, yet there are three distinct limestone units that contain dissolution caves: 1) Paleozoic (Mississippian) Tuscumbia Formation limestone; 2) Mesozoic carbonate units; and 3) Cenozoic limestone, Marianna Formation. There are a total of 44 caves known within the state based on past documentation, however the caves listed …

Hydrolgeologic Groundwater Sensitivity And Vulnerability Mapping In South Central Kentucky, Andrea Croskrey

Masters Theses & Specialist Projects

Groundwater sensitivity (Ray and O'dell 1993 a) refers to the inherent ease with which groundwater can be contaminated based on hydrogeologic characteristics. We have developed digital methods for identifying areas of varying groundwater sensitivity for a ten county area of south-central Kentucky relevant to a scale of 1: 24,000. The study area includes extensive limestone karst sinkhole plains, with groundwater that is generally extremely sensitive to contamination. Digitally Vectorized Geologic Quadrangles (DVGQs) were combined with elevation data to both identify hydrogeologic groundwater sensitivity regions and to identify zones of "high risk runoff where contaminants could be transported in runoff from …

The Effect Of Dem Resolution On The Computation Of Hydrologically Significant Topographic Attributes, David Alexander Crosby

USF Tampa Graduate Theses and Dissertations

Terrain attributes computed from Digital Elevation Models (DEMs) are widely used in hydrology and hydrologic modeling. It is important to consider that the values of the attributes can be different depending on the resolution of the DEM from which they are derived. The question arises as to how much exactly the high-resolution DEMs created through LIDAR remote sensing techniques change the values of the terrain attributes when compared to lower resolution DEMs.In this thesis a LIDAR-derived DEM of 20 feet resolution was resampled using a nearest-neighbour algorithm to various coarser resolutions to examine and quantify the effect of DEM resolution …

The Feasibility Of Establishing A Telecenter In An Urban Corridor: A Case Study Of The Sr 836/Dolphin Expressway Corridor In Miami, Florida, Anurag Komanduri

USF Tampa Graduate Theses and Dissertations

Telecenters are alternate work locations and are used as a means to reduce the commute discomfort to employees. Telecenters provide advantages to both the employees and the employers and are a good Travel Demand Management measure. The history of telecenters is relatively new. Many telecenters were established in the early 1990's with the support of the Federal and State Governments. While initial signs were encouraging, the inability of these telecenters to carry on running in the absence of continued funding made them cost intensive unsuccessful experiments. There have been fewer attempts by private individuals/ Governments to work with the concept …

Standardizing Geospatial Information For New England Conservation Lands: Data Capture Methods And Technology, Richard Sutton, Sam Merrill

GIS Applications

In 2002 The New England Environmental Finance Center and Applied Geographics issued the Feasibility Study for a GIS Inventory of New England Conservation Lands 1 describing the conservation lands data status throughout EPA Region 1 (New England). This report identified stakeholders and technologies participating in the maintenance of conservation lands data within this region. In the four years since that initial report dramatic changes have occurred in the technical means by which geographic data are delivered from their respective repositories. These changes have been most pronounced and obvious in the area of web mapping services. Web mapping services are software …

Cloud-To-Ground Flash Characteristics For Atlanta, Georgia (Usa), M.L. Bentley

Faculty Peer-Reviewed Publications

We analyzed the patterns of cloud-to-ground (CG) lightning flashes around Atlanta, Georgia (USA), a region that has undergone an intense conversion from natural to anthropogenic land uses. For the 12 yr period from 1992 to 2003, annual average CG flash densities of 6 to 8 flashes km–2 emerged around Atlanta. These values are 50 to 75% higher than in the surrounding rural areas, and comparable to flash densities along the Atlantic coast of Georgia. High flash densities extended over a large swath of Atlanta, and into Gwinnett County, a heavily suburbanized, rapidly growing county to the northeast. Urban flash production …

An Analysis Of Urban Expnasion And Loss Of Vegetation Cover In Lokoja, Using Gis Techniques, Olarewaju Oluseyi Ifatimehin

Olarewaju Oluseyi Ifatimehin

Since Lokoja became an administrative headquarters of Kogi State in 1991, it has been experiencing rapid expansion, urbanization and significant changes in its physical landscape – land use and land cover changes. This study uses remote sensing and GIS techniques combined with field checks and survey to map land use and land cover changes and to measure the rate of urban expansion and loss of vegetation in Lokoja between 1987 and 2005. There was a considerable change in land use types over the said period of the study. The built-up area, vacant land, cultivated land and other land use type …

Hydrology And Water Balance Of Devils Lake Basin: Part 1 Hydrometeorological Analysis And Lake Surface Area Mapping*

Journal of Spatial Hydrology

The spatial distribution of stocks of water is useful in studying flood, water pollution and water supply problems. Flood prone and closed basin watersheds benefit from spatial water balance studies in understanding the hydrologic processes and deal with excess water problems. In this study, we present results of a study of the hydrology Devils Lake basin of the Red River of the North, northeastern North Dakota partitioned in to two parts. Part 1 addresses the hydrometeorological analysis and lake surface area mapping of the basin and Part 2 deals with spatial surface water balance modeling using Landsat images and geographic …

Hydrology And Water Balance Of Devils Lake Basin: Part 2 Grid-Based Spatial Surface Water Balance Modeling*

Journal of Spatial Hydrology

In this part of the study, grid-based spatial water balance approach was used to estimate the annual water balance of Devils Lake basin, hydrologically closed lake located in the Red River of the North basin, northeastern North Dakota. Landsat images from 1991 to 2003 were used in the study. Using spatial precipitation, land-cover and soils data, grid-based surface runoff was estimated based on the Curve Number method. The calibrated upstream runoff inflow for each grid cell was computed using a 10-m digital elevation model. Spatial evapotranspiration was estimated for the study area from remotely-sensed data using a surface energy flux …

Rainfall-Runoff Modeling For An Experimental Watershed Of Western Greece Using Extended Time-Area Method And Gis

Journal of Spatial Hydrology

In this study, an effort was made to simulate the transformation of rainfall into runoff, in a small experimental mountainous-forested watershed in western Greece. The main objective was the production of flood hydrographs by calculating average flow velocities (inside and outside the stream network). The usefulness of the flow velocities lies in using them in other ungauged small-forested watersheds that have similar geomorphological and hydrological characteristics. The meteorological and hydrological data of four storm events were obtained from the corresponding stations that are located near and at the outlet of the watershed, respectively. Geographic Information Systems (GIS) technology was used …

Estimating Spatial Curve Number For Hydrologic Response Analysis Of A Small Watershed

Journal of Spatial Hydrology

An approach to estimate the curve number (CN) at each pixel unit of a satellite imagery, which is a key parameter in the widely used Soil Conservation Service Curve Number (SCS- CN) hydrologic model, is proposed. Instead of mapping land use and its temporal dynamics from satellite imageries, this approach linearly unmixes the multi-spectral radiances into three fractional layers which primarily control the degree of saturation within a watershed occurring due to a 25 cm-depth storm event, i.e., physically interpreted as the CN. The fraction layers used are water, sand and pure vegetation. In order to obtain a relationship between …

Estimating Spatial Sediment Delivery Ratio On A Large Rural Catchment

Journal of Spatial Hydrology

Soil erosion and sediment yield from catchments are key limitations to achieving sustainable land use and maintaining water quality in streams, lakes and other water bodies. Controlling sediment loading requires the knowledge of the soil erosion and sedimentation. However, sediment yield is usually not available as a direct measurement but estimated by using a sediment delivery ratio (SDR). An accurate prediction of SDR is important in controlling sediments for sustainable natural resources development and environmental protection. There is no precise procedure to estimate SDR, although the USDA has published a handbook in which the SDR is related to drainage area. …

Modeling For Management In A Compliance World, Christopher D. Dore, Luann Wandsnider

Department of Anthropology: Faculty Publications

In practice, compliance-driven cultural resource “management” and its requirements for resource location, evaluation, impact assessment, and mitigation manifests a fundamentally different use of geospatial predictive modeling than do research-oriented investigations. This difference primarily results from the lack of an iterative research design. In research-oriented modeling, iterations of model building and model testing gradually build a more robust model and lead to an increased understanding of the variables that condition human spatial behavior in the past. In a compliance environment, spatial models are rarely built and evaluated; rather, once built, they are applied in a single iteration. An assumption is made …

Selection Of Site For Small Hydel Using Gis In The Himalayan Region Of India

Journal of Spatial Hydrology

The choice of site for small hydro in the inaccessible tracts of Himalayan region is a difficult task by the conventional methods. This leads to a considerable loss of time and money in selecting a proper site for small hydel. In this paper an attempt has been made to use GIS and Remote Sensing technology to arrive at various alternative sites available in the study area and finally to select the most technically suitable site. The Soil Conservation Service (SCS) Curve Number (CN) method has been utilized to identify the monthly average runoff of the site. The distributed curve number …

Identifying Potential Conflict Associated With Oil And Gas Exploration In Texas State Coastal Waters: A Multi-Criteria Spatial Analysis, Samuel Brody, Himanshu Grover, Sarah Bernhardt, Zhenghong Tang, Bianca Whitaker, Colin Spence

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

Recent interest in expanding offshore oil production within waters of the United States has been met with opposition by groups concerned with recreational, environmental, and aesthetic values associated with the coastal zone. Although the proposition of new oil platforms off the coast has generated conflict over how coastal resources should be utilized, little research has been conducted on where these user conflicts might be most intense and which sites might be most suitable for locating oil production facilities in light of the multiple, and often times, competing interests. In this article, we develop a multiple-criteria spatial decision support tool that …
