Spatial Ensembling of Land Cover Models

摘要: Spatial location is a useful feature in models that use remotely sensed data. Satellite imagery, for example, can be used to estimate land cover on the surface of the earth, however both the distribution of satellite imagery and distribution of land cover will vary with location. At a macro scale, there are well defined areas over the world that contain distinct features in satellite imagery and land cover distributions such as different eco-regions. At a micro scale, spatially coherent features like``lakes''and``cities''provide a strong signal about the underlying land cover distribution. The distribution of pixels in images collected over space can differ for less obvious reasons such as the sensors used.
