1. A computer-executable method performed by a computer system, the method comprising: dynamically linking a geologic data source to a chance map via a transform; updating the chance map in real time when a change occurs in the data source; and generating an uncertainty assessment of one or more parameters of the chance map in real time based on data from the geologic data source, wherein generating the uncertainty assessment comprises determining an uncertainty of the one or more parameters based on a distribution of property values in at least a portion of the geologic data source.
