Estimating The Economic Recreational Value Of Paracas National Reserve In Ica Peru: A Fair Fee Implementation Approach, Jaqueline Garcia-Yi Dec 2004

Estimating The Economic Recreational Value Of Paracas National Reserve In Ica Peru: A Fair Fee Implementation Approach, Jaqueline Garcia-Yi

Electronic Theses and Dissertations

Paracas National Reserve (PNR) is one of the fifty-seven protected areas that belong to the National System of Protected Areas (SINANPE) of Peru. Located in Ica Department, on the Pacific coast of Peru, it is the only coastal-marine ecosystem currently protected by the Peruvian government. PNR has been internationally recognized, principally as a wintering area for bird migrations. It has been designated as a Regional Shorebird Reserve by the Western Hemisphere Shorebird Reserve Network (1991), a Ramsar site by the Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat (1992), and a Particular Sensitive Sea Area by the …

Context-Specific Preference Learning Of One Dimensional Quantitative Geospatial Attributes Using A Neuro-Fuzzy Approach, Georgios Mountrakis Dec 2004

Context-Specific Preference Learning Of One Dimensional Quantitative Geospatial Attributes Using A Neuro-Fuzzy Approach, Georgios Mountrakis

Electronic Theses and Dissertations

Change detection is a topic of great importance for modern geospatial information systems. Digital aerial imagery provides an excellent medium to capture geospatial information. Rapidly evolving environments, and the availability of increasing amounts of diverse, multiresolutional imagery bring forward the need for frequent updates of these datasets. Analysis and query of spatial data using potentially outdated data may yield results that are sometimes invalid. Due to measurement errors (systematic, random) and incomplete knowledge of information (uncertainty) it is ambiguous if a change in a spatial dataset has really occurred. Therefore we need to develop reliable, fast, and automated procedures that …

A Data Model For Exploration Of Temporal Virtual Reality Geographic Information Systems, Jorge Alberto Prado De Campos Aug 2004

A Data Model For Exploration Of Temporal Virtual Reality Geographic Information Systems, Jorge Alberto Prado De Campos

Electronic Theses and Dissertations

Geographic information systems deal with the exploration, analysis, and presentation of geo-referenced data. Virtual reality is a type of human-computer interface that comes close to the way people perceive information in the real world. Thus, virtual reality environments become the natural paradigm for extending and enhancing the presentational and exploratory capability of GIs applications in both the spatial and temporal domains. The main motivation of this thesis is the lack of a framework that properly supports the exploration of geographic information in a multi-dimensional and multi-sensorial environment (i.e., temporal virtual reality geographic information systems). This thesis introduces a model for …

Structuring A Wayfinder's Dynamic And Uncertain Environment, Michael D. Hendricks May 2004

Structuring A Wayfinder's Dynamic And Uncertain Environment, Michael D. Hendricks

Electronic Theses and Dissertations

Wayfinders typically travel in dynamic environments where barriers and requirements change over time. In many cases, uncertainty exists about the future state of this changing environment. Current geographic information systems lack tools to assist wayfinders in understanding the travel possibilities and path selection options in these dynamic and uncertain settings. The goal of this research is a better understanding of the impact of dynamic and uncertain environments on wayfinding travel possibilities. An integrated spatio-temporal framework, populated with barriers and requirements, models wayfinding scenarios by generating four travel possibility partitions based on the wayfinder's maximum travel speed. Using these partitions, wayfinders …

Expansion And Renovation Of The Darling Marine Center Library, Kevin Eckelbarger Mar 2004

Expansion And Renovation Of The Darling Marine Center Library, Kevin Eckelbarger

University of Maine Office of Research Administration: Grant Reports

This award provides partial funding for expansion and modernization of the library at The Darling Marine Center. The library currently contains more marine-related holdings than any other library in Maine, and is an important resource for researchers and students interested in the biology of the Gulf of Maine and the Maine coast. Because of current space limitations, a third of the library's holdings are stored in other buildings and attic spaces. The library is not wheelchair accessible, has no significant study space, and provides only limited access to electronic databases. The proposed changes include: 1) construction of a 1,500 sq. …
