Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: encoding one or more instance of a received image with spectral mask data, wherein the spectral mask data specifies spectral information of the received image to be masked; training one or more predictive model in dependence on the encoding; querying the one or more predictive model with a query image; and performing processing in dependence on an output from the querying.

Abstract: In some examples, a method of vector-raster data fusion includes receiving vector data for a geographical location, and statistically analyzing the vector data to obtain vector statistics. In some examples the method further includes rasterizing the vector statistics, and storing at least one of the vector data and the rasterized vector statistics together in a key-value store together with previously stored raster data for the geographical location. In some examples, the vector data further includes metadata, and the method further includes storing the metadata in at least one of the key-value store or a separate vector database.
