High resolution spectral sensing, or hyperspectral surveying, is an advanced remote sensing technique that maps the distribution of surface materials through their spectral signatures.
This technology can be applied to mineral exploration, geological mapping and environmental minesite monitoring.
The successful application of this technique depends on determining the surface spectral signature of materials of interest. With this knowledge, image data collected with airborne scanners (that have sufficient signal to noise ratio and both high spectral and spatial resolution – see HyMap specifications below) can be processed to map the distribution of the materials of interest. In geoscience applications this is termed mineral mapping.
Currently no satellite systems can match the mineral mapping results achievable from airborne imagery.
Through many years of expertise, experience and infrastructure, HyVista can offer a truly complete end-to-end service. No longer is airborne spectral imaging (hyperspectral remote sensing) just about the data. The product to be delivered to the minerals industry is a new generation of information rich maps.
HyVista Corporation’s geo-mapping solutions now offers the minerals industry a complete remote sensing based mapping service based on value adding of multi-scaled, state of the art andtraditional data sets. These include:
|•||district, tenement and deposit scale mineral maps for area selection, target generation or model formulation|
|•||supported by regional scale satellite interpretations used for stratigraphic and lithological mapping|
|•||regolith and mine environment assessments|
|•||spectral and geological field verification of its products.|
The mineral exploration industry was the first to utilise this technology, but the system’s ability to distinguish specific types of vegetation, soils and certain pollutants means it can also be applied in environmental monitoring of mine sites.
