Satellite Imaging
Discover the Possibilities
Satellite based remote sensing has become an important imaging tool in the field of environmental science. This cutting-edge technology has made it possible to remotely acquire detailed data about the earth and its resources for global as well as regional assessments. Applications include monitoring reclamation or remediation efforts, mapping annual variation and locating pipeline break areas.
Images obtained from satellite sensors can play an important role in environmental impact studies. Remote sensing and Geographic Information Systems (GIS) have allowed for greater opportunities in the areas of data integration and analysis, modeling, and map production.
Multispectral satellite imaging involves the analysis of discrete spectral bands within the visible and infrared range of the electromagnetic spectrum. The bands readily available for analysis are the red, green, blue range within the visible light spectrum and the near infrared of the non-visible spectrum.
How Does it Work?
- Satellite data is acquired as a measure of the reflective intensity of a surface feature such as hydrocarbons, soils or vegetation.
- Vegetation type, density of vegetation, bare or salt-laden soils yield a unique spectral signature which can be mapped.
- Response curves can be used to locate particular surface features and monitor them over time.
