We can plan and task a survey to match the client's requirementsand area of interest. Then process and interpret the data with results that will best suit the outcomes you require. Global Ore can task HyMap surveys Australia wide and also Internationally. The figure to the right highlights the Application of HyMap Mineral Mapping over Mt Lyell Cu/Au district in Tasmania. What is HyMAP? HyMap is a 126 band sensor which provides a leading combination of spatial resolution, spectral resolution, signal to noise ratio and image quality that places it as the World’s highest performance hyperspectral sensor. Airborne hyperspectral surveys are carried out using imaging spectrometers mounted in small twin engine aircraft. Flight lines are planned so that adjacent strips overlap ensuring complete ground cover is achieved. Each strip is composed of successive scan lines acquired by the scanner along the flight line. Flights are generally flown between 2000-5000m altitude and pixel size will vary depending upon height. The HyMap sensor has 4 spectrometers (VIS, NIR, SWIR1 and SWIR2) that each produce 32 spectral bands of imagery enabling identification of specific types of vegetation, soils and environmental pollutants. HyMap’s high detection capability for specific spectral signatures makes it particularly useful for a wide range of applications. Applications
Specifications HyMap provides 128 bands across the reflective solar wavelength region of 0.45 – 2.5 um with contiguous spectral coverage (except in the atmospheric water vapour bands) and bandwidths between 15 – 20 nm. The sensor operates in a 3-axis gyro stabilised platform to minimise image distortion due to aircraft motion. The system can be rapidly adapted into any aircraft with a standard aerial camera port. HyMap provides a signal to noise ratio (>500:1) and image quality that is setting the industry standard. The spectral configuration of the HyMap sensor is shown below for each of the 4 spectral modules containing 32 bands each, totaling 128 spectral bands.
