Light pollution of the environment.  Space monitoring of this problem.

Light pollution of the environment. Space monitoring of this problem.

Light pollution (otherwise known as backlighting) is the illumination of the night sky by artificial light sources, the light of which is scattered in the lower atmosphere, interfering with astronomical observations and changing the biorhythms of living beings, leading to the death of some of them. This phenomenon is sometimes also referred to as light smog.

Retrospective analysis and retrospective data

Retrospective analysis and retrospective data

The relationship between the past and the present is useful to track in many fields and areas of scientific endeavor. Comparison over time allows us to see not only the changes that have occurred, but also to understand the approaches that were used by predecessors.

Remote Sensing as a Method for Predicting Platinum-Metal Mineralization Based on a Study of the Eastern Sector of the Bushveld Complex

Remote Sensing as a Method for Predicting Platinum-Metal Mineralization Based on a Study of the Eastern Sector of the Bushveld Complex

This article demonstrates the possibility of using Landsat 7 ETM+ multispectral space surveys and brightness parameters to predict platinum mineralization in new promising areas. Analysis of the gravitational field has shown that platinum mineralization in the studied area is concentrated in a rather narrow range of values, which enables one to use these data as a prospecting indicator. The main conclusions were made and the ability of Landsat 7 ETM+ multispectral space surveys to forecast platinum mineralization in new promising areas was demonstrated.
