Quiet Planet

The COVID-19 outbreak and the resulting social distancing recommendations and related restrictions have led to numerous short-term changes in economic and social activity around the world, all of which may have impacts on our environment. Your challenge is to use space-based data to document the local to global environmental changes caused by COVID-19 and the associated societal responses.

Zephyr

Summary

A public platform that presents a map that correlates and overlays variables of the social-environment, with COVID-19 statistics, total number of cases, number of active cases, recovered people and deaths, adding by region.

How We Addressed This Challenge

We wanted to present environmental and social  data in a creative way, so through studies of several articles, we were able to create a platform in near real time, which presents the data in an intuitive and clear way for anyone who uses it.

How We Developed This Project

Understanding the Data

First, our challenge was to understand how Covid-19 behaves in the environment. Through reading articles, we discovered environmental variables, like temperature, air-quality, humidity,  that has a great correlation with the contamination index.

For example, when the average temperature was below 25.8 ° C, each 1 ° C rise was associated with a −4.8951% (t = −2.29, p = 0.0226)  decrease in the number of daily cumulative confirmed cases of COVID-19.

And we collected data on population density, age pyramid. To calculate whether a city was elderly, we use the Aging Index, where we divide the number of people that has age between 0-14)/ people that has age of 65+, and multiplied them with 100 


Collecting the Data

We use the SEDAC platform to collect data about the population and COVID-19 statistics.

Used the POWER plataform, filtering with temperature bellow 2 meters, relative humidity bellow 2m, and wind speed bellow 10 meters. We are using the API to collect data in real time.

And for the air quality, we integrate the API of the global partner meteormatics, collecting data about air pollution


Developing the Platform

We use Node as our Backend platform, and the No-SQL database MongoDB for saving our data. For the map, we developed using the library  GeoJS, that allow us to draw on Map, and manipulate as we want.
