The advanced near-infrared field spectroradiometer for collecting spectral measurements in the field
Geoscience, or the study of the Earth, is broken into a broad spectrum of specialized sub disciplines, including geology, mineralogy, volcanology, petrology, geochemistry, geophysics, geomorphology, paleontology, stratigraphy, structural geology, engineering geology, sedimentology, edaphology, and pedology. These classifications include scientific researchers concerned with identification of the physical characteristics of materials such as rocks, minerals, and chemical compositions found on the Earth’s surface.
Remote sensing technology is an effective and widely established analytical method for geology and mineral exploration, and has proven extremely beneficial by providing access to dangerous or previously inaccessible sites. Aerial imagery acquired from hyperspectral and multispectral imaging sensors such as Landsat, ASTER, AVIRIS, HyMap and Hyperion is applied to geological surveys, alteration zones mapping, and geomorphology applications. Satellite imagery correlated with ground truth data is also used for assessments of change due to natural events such as volcanic eruptions, floods, and earthquakes. and to indicate subtle shifts in mineralogical composition. The important aspects of these studies are supported by ground truth data collected with field portable spectroradiometers.
ASD designed the FieldSpec spectroradiometer and TerraSpec mineral analyzer systems to offer multiple configurations, resolution levels, and accessories for the collection of laboratory-quality field spectra. They feature a flexible wavelength range that covers the visible and near-infrared regions, and are ideal for measurements involving absorption and reflectance of solar radiation. Data from these highly portable field instruments is compatible with popular image analysis software packages such as ENVI, ERMapper, ERDAS Imagine and MultiSpec, allowing you to easily build focused and detailed spectral libraries tailored to your application requirements. Bringing a level of field-based portability that only ASD can provide, the FieldSpec instruments are a technical tool that helps you work in sites located in some of the most remote areas of the planet.
