Abstract: Methods and systems are described for accessing a resource having a network address associated with a location on a map. In one aspect, a map representing a network address space and a geospatial region is provided on a client configured for accessing a network addressable space. A map location in the map corresponds to a geospatial location of the resource provider in the geospatial region and to a network address of the resource provider in the network address space. The client receives resource access information for accessing the resource from the resource provider. The client determines the geospatial location of the resource provider based on the resource access information. The client associates at least a portion of the resource access information with a map location corresponding to the geospatial location of the resource provider. Access to the resource is provided, via the map, based on the resource access information.
