High-Resolution Digital 3d Models Of Algar Do Penico Chamber: Limitations, Challenges, And Potential, Ivo Silvestre M.Sc., José I. Rodrigues Phd, Mauro Figueiredo Phd, Cristina Veiga-Pires Phd

International Journal of Speleology

The study of karst and its geomorphological structures is important for understanding the relationships between hydrology and climate over geological time. In that context, we conducted a terrestrial laser-scan survey to map geomorphological structures in the karst cave of Algar do Penico in southern Portugal. The point cloud data set obtained was used to generate 3D meshes with different levels of detail, allowing the limitations of mapping capabilities to be explored.

In addition to cave mapping, the study focuses on 3D-mesh analysis, including the development of two algorithms for determination of stalactite extremities and contour lines, and on the interactive …

Spatial Analysis Of Foreclosures In Hillsborough County, Brian Arthur Sandrock

USF Tampa Graduate Theses and Dissertations

This study examines the spatial impact various socio-demographic and housing factors might have in the foreclosure lis pendens rate within various Hillsborough County, Florida tracts as well as comparing those results with past research. Hopefully the techniques used in this study can be implemented elsewhere in order to better study the foreclosure crisis. The methods used within this research were chosen carefully in order to best understand what is being observed. One method is OLS regression which helps see the impact of each variable and if that impact has a negative or positive effect on the rate of foreclosure. Bivariate …

Estimation Of Forest Interior Condition In Southern Appalachian Mountains Using Airborne Lidar Data, Gang Shao, Songlin Fei, Buddhika D. Madurapperuma, Guofan Shao

Purdue GIS Day

Sustainability of forest ecosystem requires maintenance of forest cover and forest interior conditions. Sustaining forest cover supplies ecosystem goods and services and maintains biomass and carbon and nitrogen storage. Forest interior supports ecosystem functioning and provides particular physical and biological environments for plant and animal species that depend on a type of habitat isolated from non-forest land cover areas and prohibit the infestation of invasive species. Land cover maps derived from satellite imagery were broadly applied to assess spatial patterns of forest ecosystem and its dynamic. However, existing land cover maps at landscape scale are insufficient to provide information of …

Python Tool For Managing Hydrologic Soil Data, Ilyas Orazbek

Purdue GIS Day

As a water runoff crosses different kinds of soil, it collects chemicals from those lands. We've designed a python-based tool that estimates the amount of chemicals that get collected into the water stream. This could help us determine the impact of construction on the water quality of streams in the area.

Tablet-Based Mobile Gis Approaches To Archaeological Data Collection, Ian Lindsay

Purdue GIS Day

Over the past 15 years, archaeological research in northern Armenia has documented the unique evolution of prehistoric complex societies in the South Caucasus, where complex, fortress-centered institutions emerged during the Late Bronze Age (c.1500-1150 BC) not from settled farming villages—as is more typical of archaic states—but from mobile herding communities. As the costs of archaeological fieldwork continue to rise, resulting in shorter and more intensive field seasons, researchers are leveraging new technologies to improve the efficiency and accuracy of data collection in the field. An increasingly popular solution in archaeology is the use of “paperless” site recording strategies that enhance …
