Abstract: Various embodiments are described herein for improving relevancy and accuracy of assistance data (AD) generation from a set of floor plan map data based on contextualizing parameters in the set of floor plan map data to other related floor plan maps. The relevancy and accuracy of assistance data derived from a floor plan map may be improved by contextualizing or matching the floor plan map to other related floor plan maps where associated assistance data is already recorded. In some embodiments, floor plan maps may be identified which are closely related to the new floor plan map to be analyzed, and then the measurements of the closely related floor plan map as assistance data for the new floor plan map may be reused. In some embodiments, a relationship tree graph may be used to organize the floor plan maps into a logical relationship between each other.

Abstract: Systems, apparatus and methods for converting an architectural diagram to structural elements (e.g., such as walls, hallways and open areas) for forming assistance data are presented. An architectural diagram may contain too many layers to manually review each layer. Some examples disclosed herein sort layers of an architectural diagram based on if the layer probably contains structural elements useful for forming assistance data. The sorted list of layers may be user selectable or automatically incorporated into a floor plan containing only structural elements. Once a floor plan is created from an architectural diagram, assistance data may be created and sent to a mobile device.

Abstract: Embodiments may automatically place access points (APs) on floor plans by incorporating a number of conventions for identifying types and locations of APs. These conventions may include the name of APs, MAC addresses, lat/lon information, and feature analysis or image recognition techniques for matching visual cues if the AP locations are marked on images. Some embodiment may conduct several other operations to optimize placement of APs. These optimization operations may reduce the number of steps needed to place APs on floor plans, and/or may reduce extraneous and superfluous information from the floor plans that may clutter the annotated floor plan map.
