This SBIR Phase II project will develop software and a system that enables nearly automatic generation and maintenance of a global database of indoor maps through crowdsourcing and data fusion. The current state of the art in indoor mapping relies on a manual labor-intensive process to create and maintain maps as they change over time, which is difficult to scale. A dynamic map-building system will address the challenge of generating and updating key indoor map navigation data. The developed mapping software will use existing embedded Smartphone sensors to discover building features (such as hallways, elevators, exits, and stairwells) and their connectivity as a user walks through a building while carrying a Smartphone running the mapping application. Additional building signature information is collected as part of the map. The user's location, which is simultaneously being tracked using the same sensors, is used to identify the location of the discovered building features. The map accuracy and completeness will increase as the number of users increase. This indoor map database will be used for improved indoor location and routing.The broader/commercial impact of the mapping software is that it will enable map coverage to increase beyond high use environments such as malls, airports, and museums. The dynamic map-building system enables maps to be easily extended to include all commercial buildings and to help address the challenge of maintaining and updating indoor map navigation data as they change over time. The data produced by the system will complement and integrate with indoor map data being made available by leading indoor map suppliers. Indoor maps can be used to power a wide array of applications, and they are clearly essential for making location-based applications work. These applications include consumer applications as well as critical safety applications. Locating people (including children) in emergency situations becomes possible if the software can both calculate their location and show it on a clear map that includes essential floor plan data that makes it easy to reach them. Navigating out of a building in an emergency is possible if the open pathways, stairwells, entrances, and exits are clearly marked on a map.

SBIR第二阶段项目将开发一个软件和一个系统，通过众包和数据融合，几乎自动生成和维护一个全球室内地图数据库。目前室内地图绘制的技术水平依赖于人工劳动密集型过程来创建和维护地图，因为地图随着时间的推移而变化，这很难扩展。动态地图构建系统将解决生成和更新关键室内地图导航数据的挑战。开发的地图软件将使用现有的嵌入式智能手机传感器来发现建筑特征(如走廊、电梯、出口和楼梯间)及其连接，当用户携带运行地图应用程序的智能手机穿过建筑时。其他建筑签名信息将作为地图的一部分进行收集。用户的位置同时使用相同的传感器进行跟踪，用于识别发现的建筑特征的位置。地图的准确性和完备性会随着用户数量的增加而增加。这个室内地图数据库将用于改善室内位置和路线。地图软件的更广泛/商业影响是，它将使地图覆盖范围扩大到商场、机场和博物馆等高使用率环境之外。动态地图构建系统使地图可以很容易地扩展到包括所有商业建筑，并帮助解决在室内地图导航数据随时间变化时维护和更新这些数据的挑战。该系统产生的数据将与主要室内地图供应商提供的室内地图数据相辅相成并整合在一起。室内地图可以用来支持广泛的应用程序，它们显然是基于位置的应用程序工作所必需的。这些应用包括消费者应用以及关键安全应用。如果该软件可以计算出人们(包括儿童)的位置，并将其显示在一张清晰的地图上，其中包括必要的平面图数据，从而很容易联系到他们，那么在紧急情况下定位人们(包括儿童)就成为可能。如果在地图上清楚地标出了开放的通道、楼梯间、出入口，那么在紧急情况下导航离开建筑物是可能的。
