This paper examines the performance of ChatGPT, a large language model (LLM), in a geographic information systems (GIS) exam. As LLMs like ChatGPT become increasingly prevalent in various domains, including education, it is important to understand their capabilities and limitations in specialized subject areas such as GIS. Human learning of spatial concepts significantly differs from LLM training methodologies. Therefore, this study aims to assess ChatGPT's performance and ability to grasp geospatial concepts by challenging it with a real GIS exam. By analyzing ChatGPT's responses and evaluating its understanding of GIS principles, we gain insights into the potential applications and challenges …


“I Think I Discovered A Military Base In The Middle Of The Ocean”—Null Island, The Most Real Of Fictional Places, Levente Juhasz, Peter Mooney Aug 2022

“I Think I Discovered A Military Base In The Middle Of The Ocean”—Null Island, The Most Real Of Fictional Places, Levente Juhasz, Peter Mooney

GIS Center

This paper explores Null Island, a fictional place located at 0° latitude and 0° longitude in the WGS84 (World Geodetic System 1984) geographic coordinate system. Null Island is erroneously associated with large amounts of geographic data in a wide variety of location-based services, place databases, social media and web-based maps. Whereas it was originally considered a joke within the geospatial community, this article will demonstrate implications of its existence, both technological and social in nature, promoting Null Island as a fundamental issue of geographic information that requires more widespread awareness. The article summarizes error sources that lead to data being …


An Assessment Of Climate Mobility Pressures In Response To Dynamic Sea-Level Rise, Nadia A. Seeteram Jul 2022

An Assessment Of Climate Mobility Pressures In Response To Dynamic Sea-Level Rise, Nadia A. Seeteram

FIU Electronic Theses and Dissertations

Sea-level rise (SLR) and related flooding impacts will contribute to migration across coastal communities around the world. Differential exposure to impacts, societal vulnerability, and adaptive capacity will invariably lead to varying climate-related mobility outcomes for residents of these communities. Residents of Miami-Dade County (MDC), FL, USA are at substantial risk to the direct and indirect impacts of SLR and related flooding. As the 2nd most economically unequal metropolitan area in the U.S. according to the Gini coefficient (0.508), without strategic intervention, marginalized and vulnerable communities across MDC will disproportionately face unequal mobility pressures. This dissertation seeks to understand the potential …

In this Editorial, we survey the papers included in the Special Issue, grouping …


Do Home Invasion Serial Killers Warrant A Distinct Classification From Other Serial Killer Location Types? A Retrospective Comparative Examination, Caroline V. Comerford Mar 2022

Do Home Invasion Serial Killers Warrant A Distinct Classification From Other Serial Killer Location Types? A Retrospective Comparative Examination, Caroline V. Comerford

FIU Electronic Theses and Dissertations

This dissertation seeks to address the research gap in serial homicide regarding home invasion serial killers (HISKs) and add to existing policy by providing insight and approaches to assist in serial murder investigations of such killers. Data for the study was obtained from the 2019 Radford University/Florida Gulf Coast University Serial Killer Database (RU/FGCU SKD) and additional public information searches. A retrospective comparative design and proportionate stratified random sampling of 326 serial killers from the RU/FGCU SKD (2019) were used to examine the differences and classifications of HISKs and non-home invasion serial killers (non-HISKs) in three investigations: (1) common characteristics; …

Bridges And Barriers: An Exploration Of Engagements Of The Research Community With The Openstreetmap Community, A. Yair Grinberger, Marco Minghini, Godwin Yeboah, Levente Juhasz, Peter Mooney

GIS Center

The academic community frequently engages with OpenStreetMap (OSM) as a data source and research subject, acknowledging its complex and contextual nature. However, existing literature rarely considers the position of academic research in relation to the OSM community. In this paper we explore the extent and nature of engagement between the academic research community and the larger communities in OSM. An analysis of OSM-related publications from 2016 to 2019 and seven interviews conducted with members of one research group engaged in OSM-related research are described. The literature analysis seeks to uncover general engagement patterns while the interviews are used to identify …

User-generated map data is increasingly used by the technology industry for background mapping, navigation and beyond. An example is the integration of OpenStreetMap (OSM) data in widely-used smartphone and web applications, such as Pokémon GO (PGO), a popular augmented reality smartphone game. As a result of OSM’s increased popularity, the worldwide audience that uses OSM through external applications is directly exposed to malicious edits which represent cartographic vandalism. Multiple reports of obscene and anti-semitic vandalism in OSM have surfaced in popular media over the years. These negative news related to cartographic vandalism undermine the credibility of collaboratively generated maps. Similarly, …
