Urban Cup 2023

Urban Cup 2023

Dear Participants,

Welcome to Urban Cup 2023 of the first Research Summit on Urban Science and Human Dynamics! We sincerely invite you and your team to join the fascinating journey towards data-driven urban science for sustainability and social good! With fine-grained data on urban mobility, local infrastructure, land use, gas emission as well as poverty, health insurance, education attainment, etc., we welcome you to submit an original and publicly understandable impression of urban phenomena, patterns, or connections concerning urban sustainability and social good. The impression should be aesthetically, scientifically, and accurately visualized based on your data analysis. Two or more forms of the provided data should be used, and additional information (e.g., Internet activities) may but need not be linked to. Please also make sure to submit the source codes that guide you to your amazing discoveries.

Please summarize the impression in a one-page slide and format your submission as this template. Each team should consist of no more than 3 people, with at least one team member present at the conference venue to present the impression. Please email all files to [email protected] by August 5th @ 8am (Beijing time, UTC/GMT+08:00) to complete the submission. Late submissions will not be considered.

Exemplar ideas of the impressions can be found here.

Here are downloadable U.S. datasets and England datasets.

Datasets

We provide 6 city-scale datasets collected from the largest U.S. cities and 1 sub-city scale multisourced dataset collected from 1039 middle layer super output areas (MSOAs) of 29 England cities. The vast majority of them originate from A satellite imagery dataset for long-term sustainable development in United States cities and Healthy Cities, A comprehensive dataset for environmental determinants of health in England cities published/accepted in Nature Scientific Data (IF 9.8). The datasets are briefly described as follows:

1. U.S. mobility dataset

This dataset is extracted from SafeGraph [1]. It details the monthly population movement between CBGs within the 10 largest cities in the United States from 2018.1 to 2022.4. The movements were aggregated from anonymized mobile devices. Please click here for more details about the dataset.

2. U.S. carbon emission dataset

This dataset is collected from Open-source Data Inventory for Anthropogenic CO2 (ODIAC) [2]. It records the CO2 emission within the 10 largest cities in the United States between 2018 and 2021. The data provides monthly CO2 emissions from fossil fuel combustion, cement production and gas flaring on a 1x1 km spatial resolution. Please click here for more details about the dataset.

3. U.S. air pollution dataset

This dataset is derived from the Environmental Protection Agency of the United States [3]. It is collected from air quality monitors and consists of the daily O3, SO2, NO2, CO, PM2.5, and PM10 information across the United States between 2018 and 2021. Please click here for more details about the dataset.

4. U.S. population characteristic dataset

This dataset is part of [4] and is obtained from American Community Survey (ACS), Earth Observation Group, and OpenStreetMap. It provides both CBG-level and city-level poverty, health insurance, education, income Gini & light Gini, and built environment & racial segregation data from 2014 to 2023 across the 10 largest cities in the United States. Please click here for more details about the dataset.

5. U.S. visual semantics dataset

This dataset is part of [4] and provides semantic attributes processed from satellite remote sensing data. It depicts both CBG-level and city-level urban infrastructural information from 2014 to 2023 across the 10 largest cities in the United States. Please click here for more details about the dataset.

6. U.S. basic geographical information dataset

This dataset is part of [4] and consists of basic geographical information of CBGs across the 10 largest cities in the United States between 2014 and 2021. It records the city, area, population, centroid, and boundary of the CBGs within each year. Please click here for more details about the dataset.

The data entries of the above mentioned datasets are summarized as below:

7. England environment and health datasets

This is a fine-grained and multi-sourced environment and health dataset collected from cities in England, which is published in our Nature Scientific Data paper (IF 9.8) [5]. The corresponding data repo is available at here. It records the health outcomes of citizens covering physical health (COVID-19 cases, asthma medication expenditure, etc.), mental health (psychological medication expenditure), and life expectancy estimations. It presents the corresponding environmental determinants from four perspectives, including basic statistics (population, area, etc.), behavioural environment (availability of tobacco, health-care services, etc.), built environment (road density, street view features, etc.), and natural environment (air quality, temperature, etc.). To reveal regional differences, this dataset extracts and integrates massive environment and health indicators from heterogeneous sources into two unified spatial scales, i.e., at the middle layer super output area (MSOA) and the city level, via big data processing and deep learning techniques.

A comprehensive data table that contains all the subsections is also provided, which is organized into a long table with columns as follows:

Column Name	Description	Example
TopCategory	The top category of the dataset.	HealthOutcome, EnvironmentalDeterminants
SecondCategory	The second category of the dataset.	PhysicalHealth, MentalHealth, LifeExpectancy, NaturalEnvironment, BehaviourEnvironment, BuiltEnvironment, BasicStatistics
ThirdCategory	The third category of the dataset.	DementiaExpenditure, Weather, TobaccoAvailability, RoadDensity, Population
CityCode	Exclusive ID for each city.	J01000007
CityName	Name of the city.	Birmingham
MSOACode	Exclusive ID for each MSOA.	E02001834
MSOAName	Name of the MSOA.	Birmingham 008
Time	Time of the data record. For those without timestamps, None is filled to this column.	2019-01-01
Key	Specifications of the record, such as Mean for HousePrice and Female for LifeExpectancy	Mean, Female, PM2.5
Value	Value of the data record.
