1. A method for providing geospatial assets, the method comprising: receiving, by one or more computing devices, event data associated with a user from a local computing device, the event data corresponding to location information associated with at least one travel-related event for the user that is expected to occur in the future; determining, by the one or more computing devices, a predicted region of interest for the user based on the event data, the predicted region of interest corresponding to a geographical region of a master geospatial asset; generating, by the one or more computing devices, a portable geospatial asset based on the predicted region of interest, the portable geospatial asset corresponding to a 2-D map or a 3-D globe that includes a data subset of the master geospatial asset; and transmitting, by the one or more computing devices, the portable geospatial asset to the local computing device.
