Decision Making on Allocating Urban Green Spaces Based upon Spatially-Varying Relationships between Urban Green Spaces and Urban Compaction Degree

Hsueh-Sheng Chang, Tzu-Ling Chen
2015 Sustainability  
Overall, the exploration of conceptualizing spatial heterogeneity of relationships between the degree of urban compaction and UGS can provide insightful analyses for decision-making on allocating UGS.  ...  High population density attracts even more residents and frequently renders the existing urban green space (UGS) insufficient for use as part of a living environment.  ...  Acknowledgments Support from the National Science Council of ROC through grant NSC 102-2410-H-006-074 is gratefully acknowledged.  ...

Quantifying altitude of human habitation in studies of human health using geographical name server data

Stephen Thielke, Christopher G. Slatore, William A. Banks
2016 Geospatial Health  
Almost all studies examining the effects of altitude on human health have estimated the geographical altitude of defined regions, yet the primary interest lies in where people live, not the land around  ...  We propose a straightforward and computationally simple method for estimating the average altitude of habitation within the regional units for which health statistics are typically reported (such as counties  ...  Limitations First, because there is no differentiation of place names based on their size, our technique may underestimate the population density of highly populous places.  ...

Electric Vehicle Charging Stations Coverage: A Study of Slovenia

2022 Tehnički Vjesnik  
Using discrete and network geographic information system (GIS) models, with ArcGIS software, the density of electric vehicle charging stations (EVCSs), geographic distribution, nearness along a street  ...  Spatial analyses are carefully selected, and, in complementarity, give a comprehensive picture of EVCSs coverage. The research is important for further spatial planning of EVCSs.  ...  As the above analyses hinted at a relationship between EVCSs and motorways, we examined this relationship in more detail.  ...

Types of Crime, Poverty, Population Density and Presence of Police in the Metropolitan District of Quito

Pablo F. Cabrera-Barona, Gualdemar Jimenez, Pablo Melo
2019 ISPRS International Journal of Geo-Information  
Correlation analyses were applied between number of registers of each type of crime, and the UBN index, CPU density and population density measures.  ...  An inverse relationship between the UBN index and number of crimes was identified for each type of crime, while positive relationships were found between crimes and CPU density, and between crimes and  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

Improving Estimates of Natural Resources Using Model-Based Estimators: Impacts of Sample Design, Estimation Technique, and Strengths of Association

John Hogland, David L. R. Affleck
2021 Remote Sensing  
While common, model-based inference alone assumes that a given model accurately depicts the relationship between response and predictors across all populations.  ...  The findings indicate that model-based estimators derived from samples spread and balanced across predictor variable space reduce the variability of population and unit-level estimators.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...
