The potential use of satellite observed nighttime lights for estimating carbon-dioxide (CO₂) emissions has been demonstrated in several previous studies. However, the procedures for a moderate resolution (1 km² grid cells) global map of fossil fuel CO₂ emissions based on nighttime lights are...

We have produced annual estimates of national and global gas flaring and gas flaring efficiency from 1994 through 2008 using low light imaging data acquired by the Defense Meteorological Satellite Program (DMSP). Gas flaring is a widely used practice for the disposal of associated gas in oil...

AbstractSightseeing air tours have proven to be a challenging management issue for many tourist destinations around the world, especially at locations meant to protect natural and cultural resources and wilderness character. Two of the primary challenges with managing air tours are a lack of...

Several studies have been carried out relating nighttime lights with economic activity. But most studies relating nighttime lights with economic activity have focused on associating higher totals in economic activity with higher sum of lights across regions. The question addressed in this paper...

As the world's most traded commodity, oil production is typically well monitored and analyzed. It also has established links to geopolitics, international relations, and security. Despite this attention, the illicit production, refining, and trade of oil and derivative products occur all over...

Accurately measuring oil production in low-governance contexts is an important task. Many terrorist organizations and insurgencies -- including the Islamic State group, also known as ISIL/ISIS or Daesh -- tap oil as a revenue source. Understanding spatial and temporal variation in production in...
