1. A processor-based system for generating a probability map, comprising: at least one processor configured to: receive data associated with a quantity to be mapped; apply a processor-based mapping algorithm to generate a first map of values for the quantity within an area of interest; modify at least one or more of data provided as input to the mapping algorithm or one or more input parameters associated with the mapping algorithm and generate at least a second map of values for the quantity within the area of interest; and generate a probability map associated with the quantity based on the first and second maps.
