The primary objective of this research proposal is to develop a multi-sensor system that assists in the precise mapping of infrastructure for its development and management. It has been estimated that between $25-trillion and $30-trillion will be injected into global infrastructure projects over the coming two decades (Financial Post, 26 January 2009). In Canada alone, there is already a commitment of $12 billion for 2009/10 and the total domestic price tag is eventually deemed to be several hundred billion dollars. Costs associated with transportation projects account for a significant portion of the overall infrastructure costs. One of the identified tasks is the creation of a georeferenced infrastructure inventory recording the location, condition, and estimated replacement value of each municipal asset. The second is the worker safety on infrastructure construction projects, specifically sub-surface construction projects. Public and worker safety is jeopardized when municipalities do not have an accurate record of the location and condition of subsurface infrastructure. Unfortunately, this aspect is well documented with tragic results. A report from North Carolina State University states that there is one death per day (globally) due to punctured sub-surface utilities. There have been many examples of these tragedies in several countries around the world. This research endeavour will focus on the use of multiple position, orientation, and stress-related sensors for the precise determination of existing assets (including sub-surface utilities), construction site surface topography and subsurface character/structure in order to assist the construction site planner/designer, field maintenance and construction site personnel complete their respective tasks in an efficient, safe and economical manner. This research will focus on the calibration aspects of each of these sensors in an integrated environment in order to maximize the attainable horizontal, vertical and attribute accuracies required in a real-time construction and infrastructure maintenance environment.

这项研究计划的主要目标是开发一个多传感器系统，帮助精确绘制基础设施的地图，以促进其发展和管理。据估计，在今后20年中，将有25万亿至30万亿美元注入全球基础设施项目（《金融邮报》，2009年1月26日）。仅在加拿大，2009/10年度已经有120亿美元的承诺，国内总价格最终被认为是数千亿美元。与运输项目有关的费用占基础设施总费用的很大一部分。确定的任务之一是创建一个地理参考基础设施清单，记录每个市政资产的位置、状况和估计重置价值。 第二是基础设施建设项目，特别是地下建筑项目的工人安全。 当市政当局没有地下基础设施位置和状况的准确记录时，公众和工人的安全就会受到威胁。 不幸的是，这方面有充分的记录，结果悲惨。 北卡罗来纳州州立大学的一份报告指出，由于地下公用事业设施被刺破，每天（全球）有一人死亡。在世界各地的一些国家，有许多这样的悲剧。 这项研究工作的重点将是使用多个位置，方向和应力相关的传感器，用于精确确定现有资产（包括地下设施），施工现场表面地形和地下特征/结构，以帮助施工现场规划师/设计师，现场维护和施工现场人员以有效，安全和经济的方式完成各自的任务。 这项研究将集中在这些传感器中的每一个在综合环境中的校准方面，以最大限度地提高实时施工和基础设施维护环境中所需的水平，垂直和属性精度。
