ABSTRACT

The primary objective of this project is to explore the complex connection between area and

population density through the application of data science techniques. By harnessing diverse

datasets and employing advanced statistical models, we thoroughly examine the dynamics of

density and reveal underlying patterns, emerging trends, and valuable insights. Our analysis

sheds light on the intricate interplay between population distribution and geographic

dimensions, offering essential information for urban planning, resource allocation, and

promoting sustainable development.

Keywords: Density dynamics, area, population, data science, spatial distribution, urban

planning, resource allocation, sustainable development

INTRODUCTION

This project focuses on examining the

correlation between the area and

population of cities in California. The goal

is to visually represent this relationship

through a scatter plot, where the size of

points corresponds to both the city's area

and population, with larger points

indicating cities with larger sizes and

populations.

To provide clarity and understanding, a

legend will be incorporated, explicitly

specifying the scale of the point sizes used

in the plot. This legend will be created

using labeled data with no entries,

enabling a clear interpretation of the point

size scale. Understanding the distribution

and dynamics of population density across

different cities holds significant

importance for various fields, including

urban planning, resource allocation, and

policy-making. Through this analysis,

insights into the spatial distribution and

density patterns within California will be

gained.

To commence the analysis, comprehensive

data on the areas and populations of cities

throughout California will be gathered

from reliable sources such as census data,

official records, and geographic databases.

This data will form the foundation for the

subsequent visualization and analysis.

A scatter plot will be created, with each

point on the plot representing an individual

city. The size of each point will be

proportional to both the area and

population of the corresponding city. This

visualization approach will facilitate a

meaningful comparison of city sizes and

population densities within California.

In order to offer clarity and context to the

scatter plot, a legend will be included. The

legend will precisely outline the scale of

point sizes used, aiding viewers in

interpreting the plot accurately. Uniquely,

the legend will be generated using labeled

data with no entries, effectively

demonstrating the relationship between

point size and the corresponding area and

population ranges. The main objective of

this project is to provide a comprehensive

understanding of the relationship between

area and population in California cities.

The insights derived from this analysis can

have practical implications for urban

planning strategies, infrastructure

development, and resource allocation

within the state.

By adopting a scatter plot visualization and

incorporating a legend created with labeled

data but no entries, this project aims to

clarify the point size scale and facilitate a

clear interpretation of the plot. The

findings obtained from this analysis can

contribute to evidence-based decision-

making in various fields, aiding in the

development of more efficient urban

planning, resource allocation, and policy

implementation in California.[1]

Spatial Variations in Fertility of South Korea: A Geographically Weighted Regression Approach

Article

Full-text available

Jun 2019
ISPRS

South Korea has witnessed a remarkable decline in birth rates in the last few decades. Although there has been a large volume of literature exploring the determinants of low fertility in South Korea, studies on spatial variations in fertility are scarce. This study compares the Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) models to investigate the potential role of the spatially heterogeneous response of the total fertility rate (TFR) to sociodemographic factors. The study finds that the relationships between sociodemographic factors and TFRs in South Korea vary across 252 sub-administrative areas in terms of both magnitude and direction. This study therefore demonstrates the value of using spatial analysis for providing evidence-based local-population policy options in pursuit of a fertility rebound in South Korea.

Interoperability of Direction-Finding and Beam-Forming High-Frequency Radar Systems: An Example from the Australian High-Frequency Ocean Radar Network

Article

Full-text available

Feb 2019

Direction-finding SeaSonde (4.463 MHz; 5.2625 MHz) and phased-array WEllen RAdar WERA (9.33 MHz; 13.5 MHz) High-frequency radar (HFR) systems are routinely operated in Australia for scientific research, operational modeling, coastal monitoring, fisheries, and other applications. Coverage of WERA and SeaSonde HFRs in Western Australia overlap. Comparisons with subsurface currents show that both HFR types agree well with current meter records. Correlation (R), root-mean-squares differences (RMSDs), and mean bias (bias) for hourly-averaged radial currents range between R = (−0.03, 0.78), RMSD = (9.2, 30.3) cm/s, and bias = (−5.2, 5.2) cm/s for WERAs; and R = (0.1, 0.76), RMSD = (17.4, 33.6) cm/s, bias = (0.03, 0.36) cm/s for SeaSonde HFRs. Pointing errors (θ) are in the range θ = (1°, 21°) for SeaSonde HFRs, and θ = (3°, 8°) for WERA HFRs. For WERA HFR current components, comparison metrics are RU = (−0.12, 0.86), RMSDU = (12.3, 15.7) cm/s, biasU = (−5.1, −0.5) cm/s; and, RV = (0.61, 0.86), RMSDV = (15.4, 21.1) cm/s, and biasV = (−0.5, 9.6) cm/s for the zonal (u) and the meridional (v) components. Magnitude and phase angle for the vector correlation are ρ = (0.58, 0.86), φ = (−10°, 28°). Good match was found in a direct comparison of SeaSonde and WERA HFR currents in their overlap (ρ = (0.19, 0.59), φ = (−4°, +54°)). Comparison metrics at the mooring slightly decrease when SeaSonde HFR radials are combined with WERA HFR: scalar (vector) correlations for RU, V, (ρ) are in the range RU = (−0.20, 0.83), RV = (0.39, 0.79), ρ = (0.47, 0.72). When directly compared over the same grid, however, vectors from WERA HFR radials and vectors from merged SeaSonde–WERA show RU (RV) exceeding 0.9 (0.7) within the HFR grid. Despite the intrinsic differences between the two types of radars used here, findings show that different HFR genres can be successfully merged, thus increasing current mapping capability of the existing HFR networks, and minimising operational downtime, however at a likely cost of slightly decreased data quality.

Assessment of Aquarius Sea Surface Salinity

Article

Full-text available

Aug 2018

Aquarius was the first NASA satellite to observe the sea surface salinity (SSS) over the global ocean. The mission successfully collected data from 25 August 2011 to 7 June 2015. The Aquarius project released its final version (Version-5) of the SSS data product in December 2017. The purpose of this paper is to summarize the validation results from the Aquarius Validation Data System (AVDS) and other statistical methods, and to provide a general view of the Aquarius SSS quality to the users. The results demonstrate that Aquarius has met the mission target measurement accuracy requirement of 0.2 psu on monthly averages on 150 km scale. From the triple point analysis using Aquarius, in situ field and Hybrid Coordinate Ocean Model (HYCOM) products, the root mean square errors of Aquarius Level-2 and Level-3 data are estimated to be 0.17 psu and 0.13 psu, respectively. It is important that caution should be exercised when using Aquarius salinity data in areas with high radio frequency interference (RFI) and heavy rainfall, close to the coast lines where leakage of land signals may significantly affect the quality of the SSS data, and at high-latitude oceans where the L-band radiometer has poor sensitivity to SSS.

Citizen Bio-Optical Observations from Coast-and Ocean and Their Compatibility with Ocean Colour Satellite Measurements

Article

Full-text available

Oct 2016

Marine processes are observed with sensors from both the ground and space over large spatio-temporal scales. Citizen-based contributions can fill observational gaps and increase environmental stewardship amongst the public. For this purpose, tools and methods for citizen science need to (1) complement existing datasets; and (2) be affordable, while appealing to different user and developer groups. In this article, tools and methods developed in the 7th Framework Programme of European Union (EU FP 7) funded project Citclops (citizens' observatories for coast and ocean optical monitoring) are reviewed. Tools range from a stand-alone smartphone app to devices with Arduino and 3-D printing, and hence are attractive to a diversity of users; from the general public to more specified maker-and open labware movements. Standardization to common water quality parameters and methods allows long-term storage in regular marine data repositories, such as SeaDataNet and EMODnet, thereby providing open data access. Due to the given intercomparability to existing remote sensing datasets, these tools are ready to complement the marine datapool. In the future, such combined satellite and citizen observations may set measurements by the engaged public in a larger context and hence increase their individual meaning. In a wider sense, a synoptic use can support research, management authorities, and societies at large.
