1. A non-transitory computer-readable medium encoding instructions which, when executed by a computer system comprising at least one processor, cause the at least one processor to:

  • identify a prior 2-D surveyed area according to a first set of gas emission survey data resulting from a first mobile measurement run performed by a mobile measurement device along a first measurement path, the first set of gas emission survey data comprising a trajectory of the first measurement path and a first set of associated atmospheric condition data characterizing the first mobile measurement run, wherein the prior 2-D surveyed area comprises a plurality of indicators of whether corresponding locations within the prior 2-D surveyed area have been surveyed following the first mobile measurement run; and

    perform a Bayesian update of the prior 2-D surveyed area to generate a posterior 2-D surveyed area according to a second set of gas emission survey data resulting from a second mobile measurement run, the second set of gas emission survey data comprising a second set of associated atmospheric condition data characterizing the second mobile measurement run, wherein the posterior 2-D surveyed area comprises a plurality of indicators of whether corresponding locations within the posterior 2-D surveyed area have been surveyed following the first mobile measurement run and the second measurement run.
