1. An analyzer configured to compute data weights and transmission times of a digitized map, the analyzer comprising: a target resolution selector configured for inputting a display screen resolution of an end-user computing device; a target client bandwidth selector configured for inputting an available bandwidth of the end-user computing device; a data weight scale configured to, for a first selected map scale in a set of randomly selected map scales, compute a data weight associated with the digitized map at the first selected map scale, wherein the data weight reflects an amount of information included in the digitized map at the first selected map scale; and a transmission time scale configured to compute, based on the data weight, a transmission time associated with the digitized map at the first selected map scale, wherein the transmission time reflects an amount of time needed to transmit the information included in the digitized map at the first selected map scale to a target client given the target resolution and the target client bandwidth, wherein the navigability of the digitized map at the first selected map scale is determined by comparing the transmission time with a pre-determined navigability threshold.
