Context Optimized and Spatial Aware Dummy Locations Generation Framework for Location PrivacyJournal of Geovisualization and Spatial Analysis - Tập 6 - Trang 1-12 - 2022
Aditya Tadakaluru
Location-based services (LBS) involve customizing service offerings based on
users’ current location. Location privacy is a major concern with location-based
services since LBS services involve the user sharing their true location with
the LBS servers and are exposed to risk associated with the possible misuse of
the user’s true location. Dummy locations technique is one of the well-known
approach... hiện toàn bộ
Modifying the Contact Perimeter Approach for Measuring Urban Compactness Gradients in the Joglosemar Urban Region, IndonesiaJournal of Geovisualization and Spatial Analysis - Tập 7 - Trang 1-20 - 2023
Dimas Danar Dewa, Imam Buchori, Iwan Rudiarto, Anang Wahyu Sejati
The rapid and uncontrolled urbanization in developing countries creates new
challenges for the government, as is the case with mega-urbanization in the
Joglosemar Urban Region of Indonesia. This study employs remote sensing data to
assess discrete compactness with a contact perimeter approach to measure the
spatial pattern of three urban areas as the urban growth centers of the
Joglosemar Urban Re... hiện toàn bộ
Integrating Multiscale Geospatial Analysis for Monitoring Crop Growth, Nutrient Distribution, and Hydrological Dynamics in Large-Scale Agricultural SystemsJournal of Geovisualization and Spatial Analysis - Tập 8 - Trang 1-40 - 2024
Olatunde D. Akanbi, Deepa C. Bhuvanagiri, Erika I. Barcelos, Arafath Nihar, Brian Gonzalez Hernandez, Jeffrey M. Yarus, Roger H. French
Monitoring crop growth, soil conditions, and hydrological dynamics are
imperative for sustainable agriculture and reduced environmental impacts. This
interdisciplinary study integrates remote sensing, digital soil mapping, and
hydrological data to elucidate intricate connections between these factors in
the state of Ohio, USA. Advanced spatiotemporal analysis techniques were applied
to key dataset... hiện toàn bộ
A UWB-Based Indoor Positioning System Employing Neural NetworksJournal of Geovisualization and Spatial Analysis - Tập 4 - Trang 1-9 - 2020
Binghao Li, Kai Zhao, Eduardo Benitez Sandoval
Because of its high time-domain resolution, ultra-wideband (UWB) technology is
capable of precise range measurement and has been applied in many accurate
indoor positioning systems. This paper presents a practical indoor positioning
and navigation system using the UWB modules we developed based on Decawave UWB
chipset. In order to enhance the performance of the system in NLOS scenarios, a
neural n... hiện toàn bộ

From Data to Narratives: Scrutinising the Spatial Dimensions of Social and Cultural Phenomena Through Lenses of Interactive Web MappingJournal of Geovisualization and Spatial Analysis - - 2022
Tian Lan, Oliver O’Brien, James Cheshire, Alex Singleton, Paul Longley
Modern web mapping techniques have enhanced the storytelling capability of
cartography. In this paper, we present our recent development of a web mapping
facility that can be used to extract interesting stories and unique insights
from a diverse range of socio-economic and demographic variables and indicators,
derived from a variety of datasets. We then use three curated narratives to show
that on... hiện toàn bộ
