Abstract: A network system determines and remediates dissimilarities between a digital map and trace data of a road network in an area as service providers and service requesters coordinate service using the road network in the area. To determine dissimilarities the network system can select and convert a digital map, aggregate received trace data into trace data accurately representing the road network in the area, generate a visualization of the dissimilarities, and remediate the dissimilarities using a variety of methods. A first remediation method includes verifying the dissimilarity using a single service provider, a second method includes verifying the dissimilarity leveraging multiple service providers, and a third method modifies the methods used to determine dissimilarities. After remediation, the network system can generate a map of the area that accurately represents the road network in the area.

Abstract: A system for the arrangement of cards. One or more connection indices may be located along the edges of one or more cards. Connection indices may permit displaced alignments of one or more cards. Two or more cards having displaced alignments may form an irregular chain of cards. Cards may have constituent pictographs incorporating connection indices of the cards. An irregular chain of cards may form an aggregate pictograph across the connections indices of the cards in the chain. The nature of the constituent pictographs and the locations of connection indices on cards may determine the form of the irregular chain or an aggregate pictograph.
