Beyond medical data on the incidence of road injuries and their resulting morbidity and mortality, a detailed understanding of their economic implications is a prerequisite for sound, evidence-based policy making. Road injuries are among the ten leading causes of death worldwide and also impede economic wellbeing and macroeconomic performance. This task has broad implications for disaster preparedness, the environment, infrastructure development, and epidemic prevention. We demonstrate that despite the moderate resolution of the data, we are able to track individual building identifiers over time. Performance is measured with the newly developed SpaceNet Change and Object Tracking (SCOT) metric, which quantifies both object tracking as well as change detection.

We demonstrate methods to track building footprint construction (or demolition) over time, thereby directly assessing urbanization. Label fidelity exceeds image resolution this "omniscient labeling" is a unique feature of the dataset, and enables surprisingly precise algorithmic models to be crafted. address), which permits tracking of individual objects over time.

Each building is assigned a unique identifier (i.e. This open source dataset consists of medium resolution (4.0m) satellite imagery mosaics, which includes 24 images (one per month) covering >100 unique geographies, and comprises >40,000 km2 of imagery and exhaustive polygon labels of building footprints therein, totaling over 11M individual annotations.

To help address this deficit and develop novel computer vision methods for time series data, we present the Multi-Temporal Urban Development SpaceNet (MUDS, also known as SpaceNet 7) dataset.

For example, quantifying population statistics is fundamental to 67 of the 231 United Nations Sustainable Development Goals Indicators, but the World Bank estimates that over 100 countries currently lack effective Civil Registration systems. Satellite imagery analytics have numerous human development and disaster response applications, particularly when time series methods are involved.
