COVID-19 Human Activity Monitoring (HAM) with Satellite Synthetic Aperture Radar (SAR) Observations is a NASA-funded project to monitor human activity level change around the world due to COVID-19 lockdown and re-opening. Scientists at NASA’s Jet Propulsion Laboratory are processing a large volume of satellite radar data to produce maps of human activity level for about 100 major cities in the world to address the following questions:

  1. How have reductions in human activity varied across different cities?
  2. Do reductions in activities correspond to the different levels of success of different cities in controlling outbreaks of the virus? 

Parking lots are usually exposed to satellites and can represent human activity level. In order to validate and quantitatively analyse their results, they are currently trying to classify a number of ground targets in Los Angeles County into several business types. However, the relevant parking lot locations, shapes, and extents vary from one business to another.

They requested GISCorps volunteers to draw a polygon of the parking lot of each given business. 20 volunteers have been deployed to the project.

Recruitment complete, project in progress
