1. A method of partitioning map data for industrial vehicle navigation in a physical environment, wherein: the physical environment comprises static features representing objects that do not change within the physical environment and dynamic features representing objects that change within the physical environment; the industrial vehicle comprises a mobile computer and a sensor array communicably coupled to the mobile computer; the mobile computer comprises a central processing unit and a memory comprising an environment based navigation module, a feature selection module, map data representing static features within the physical environment, and a plurality of sub-area maps; the sensor array comprises a plurality of devices mounted to the industrial vehicle for monitoring the physical environment and producing sensor data representing the physical environment; and the method comprises segmenting the physical environment, as represented by the map data, into a plurality of sub-areas with corresponding map data stored in the plurality of sub-area maps, utilizing the environment based navigation module and environmental features extracted from the sensor data to determine a location of the industrial vehicle relative to a particular sub-area, utilizing the environment based navigation module to derive respective pose uncertainties associated with the dynamic features based upon data comprising noise in the sensor data and uncertainty in the determined location of the industrial vehicle; selecting a sub-area map for use by the environment based navigation module based on the determined location of the industrial vehicle, updating the selected sub-area map to include dynamic features within the particular sub-area corresponding to the selected sub-area map based on environmental features in the sensor data produced by the sensor array and the respective pose uncertainties associated with the dynamic features within the particular sub-area, utilizing the feature selection module to manage the addition of dynamic features to the sub-area map based on the respective pose uncertainties associated with the dynamic features, utilizing the environment based navigation module, the sensor data, and the updated sub-area map to determine an updated location of the industrial vehicle, and navigating the industrial vehicle using the updated sub-area map and the updated location of the industrial vehicle.
