Optimal Strategies For Grassland Restoration To Increase Spatial Carrying Capacity Of Florida Sandhill Cranes In Pasco County, Florida, Ibrahim Kaya
USF Tampa Graduate Theses and Dissertations
The Florida sandhill crane (Antigone canadensis pratensis) is a non-migratory bird species occurring throughout the Florida peninsula and the Okefenokee Swamp in southeastern Georgia. Human land-altering activities have led to a substantial decline in the amount and condition of suitable habitat, including grasslands, for the species in Florida, thereby decreasing the population size significantly. Grasslands located in close proximity to nesting locations are one of the habitat types on which the population viability of the species depends, as they provide foraging and brooding habitat which is crucial for successful reproduction. The purpose of this study is to propose the most …

Efficient Viewshed Computation Algorithms On Gpus And Cpus, Faisal F. Qarah
USF Tampa Graduate Theses and Dissertations
Nowadays with the advance in managing and collecting large data, GIS is one of the applications that suffer from lack of efficient data management methods. GIS data often come in form of maps with different types of data such as temperature, topology, and population.
This dissertation focuses on exact-viewsheds computation for large terrains, and due to the poor performance of current exact-viewshed algorithms that may need several hours to process a midsize map, we found the need for new algorithms that are capable of efficiently computing viewshed for large size maps. This work presents a highly-efficient exact-viewshed computation algorithm based …
Assessment Of Land Cover Change In St. Martin’S Marsh Aquatic Preserve, Florida, Usa, Katie Wagner
Assessment Of Land Cover Change In St. Martin’S Marsh Aquatic Preserve, Florida, Usa, Katie Wagner
USF Tampa Graduate Theses and Dissertations
St. Martin’s Marsh Aquatic Preserve (SMMAP) is a 28,461 acre (115.18 km2) preserve located on the coast of Citrus County, Florida, USA. There has been no published research that focused on coastal change on this unique coast. This thesis research focuses on coastal land cover change that has occurred within the preserve from 1988 to 2018. Multitemporal Landsat images were classified using a support vector machine (SVM) classification, while changes in vegetation were evaluated using the normalized difference vegetation index (NDVI). Field research was conducted to examine nineteen sites for classification training and test data and notes on habitat composition. …
