With the increase in the population density and the ever expanding conversion of land from rural to urban, the urban heat island (UHI) effect has become a problem of critical importance. Land cover type and land surface temperature (LST) in urban and rural areas display significant differences, such as higher LST and lower moisture content, with increasing urbanization.

The combination of high spectral resolution optical and thermal infrared imagery of the proposed HyspIRI mission will provide a powerful capability for more precise land cover type discrimination and ecosystem monitoring than possible using current satellite systems, such as mapping of cover types, aquatic and terrestrial ecosystem identification, vegetation/soil nutrient and moisture content determinations and assessment of the ecosystems function and health.

By fusion of spectroscopy and thermal remote sensing, this study assesses the potential of HyspIRI-like data for delineating land covers and vegetation types, discriminating natural versus urban ecosystems, and assessing ecosystems diversity and health.
