Abstract

Three-dimensional city modeling has gained interest recently due to its useful applications. It plays an important role in decision making and can be used comprehensively for urban planning analysis, disaster management, tourism, and other fields. One particular field where it is highly important is in civil and construction engineering. The opportunity to utilize such information has not only improved efficiency but provided the opportunity to explore innovative solutions and offer alternate options in decision making. Unmanned Aircraft Systems (UAS) are emerging as an alternative tool for mapping and modeling cities at a medium scale. The investigation of the dense point clouds created from imagery acquired by these systems is required to understand the limitations and accuracy of the derived product. For this reason, an analysis was performed to test and evaluate the capabilities of UAS based mapping for city modeling and surface reconstruction. In this study, a UAV was flown over the Westland Building Group in Ontario, CA. The drone collected overlapping images during a preset trip using a compatible IOS application, which were processed using software called ContextCapture. The UAS image-based results are compared to a high-resolution surface model that was acquired by Terrestrial Laser Scanning (TLS). At this point in the research, the data is being compared between the two systems, by performing a cloud to cloud comparison on CloudCompare. This study intends to compare UAS based mapping methods with laser scanning techniques and aims to demonstrate that in some cases, the UAS based mapping may be a more cost-effective alternative for 3D city modeling.
