  *Hyperspectral datasets are very large and cumbersome to work with (imagine 224 pieces of information—one for each band—stored for each pixel in an image). Data can be interpreted into maps so that the information can be shared in much more manageable datasets. Though many in the industry still appreciate the 7-band LANDSAT images (which can be made through data aggregation of hyperspectral images), there are four common types of maps that are created from hyperspectral data for use in geothermal exploration, including mineral maps, cultural maps, vegetation maps, and high-resolution photographs. *There are many commercial vendors that provide data products from calibrated radiance to surface reflectance to derived mineral maps. Since processing techniques vary widely in creating surface mineral maps it's a good practice for derived products to be reviewed by geologists for quality control.

Pitfalls <br> *Hyperspectral mapping of hydro
<br> *Hyperspectral mapping of hydrothermal minerals has been complicated in the past by the difficulty in displaying millions of categorized pixels in a way that is meaningful to geologists and fits with geophysical and geological mapping norms. Such issues have been resolved in the last five years with the advent of ‘targeting’ maps that plot mineral assemblages of interest in a myriad of ways including as density maps (that look similar to geophysical gradient maps) and as small, but easily accessible digital files compatible with not only standard software, but also web-based portals such as Google Earth. Mineral assemblage maps are a useful way for presenting and understanding both airborne and satellite spectral images. They ultimately provide a way to rapidly map vast areas of land (tens of thousands of acres), targeting areas with prospective hydrothermal mineral assemblages for more in-depth geothermal prospecting (i.e. high resolution geophysics and field mapping).
