Machine Learning for Geospatial Data Processing in Earth Sciences

Machine Learning for Geospatial Data Processing in Earth Sciences

The physical surface of the landscape is undergoing transformation either naturally or due to human interference, giving rise to Land Cover Land Use Change (LCLUC). Expanding urban regions and consequent LCLUC have emerged as one of the major anthropogenic sources of global environmental degradation, bringing numerous stresses to landscapes, vegetation, habitats, water, etc. LCLUC at a sub-continent to global level can be monitored through high temporal and low spatial resolution data, such as those obtained from Landsat at 30 m or MODIS Terra/Aqua at 250 m spatial resolution. These satellites improve the ability to map large areas of Earth’s surface quickly due to their wider IFOV and inexpensively. However, different land cover (LC) types jointly occupy a single pixel, and the resulting spectral measurement is a composite of the individual spectra. The intrinsic scale of spatial variation in LC is usually finer than the scale of sampling imposed by the image pixels. Due to scale-resolution mismatch, the spatial resolution of the details on the ground is less than what is required, leading to sub-pixel heterogeneity, imposing limitations in modelling with these data sets. The talk will present some attempts to resolve the mixed pixel problem and also discuss some of the emerging challenges in geospatial research.
