Abstract
3D city model and their variety applications has been of interests of many users especially the government entities. This is because the applications of 3D city model are tremendous. There are different approaches of creating 3D city model, generally, most of raw datasets used are the point cloud data obtained from the LIDAR (Light Detection and Ranging) technology and the aerial images. In Thailand, it has been of an interest if currently available LIDAR data and aerial images; which were collected over the area of Chaophraya river basin in Thailand, are able to be used for creating 3D city model. These collected datasets had not yet been proved their eligibility to do so. The goals/objectives of this study/project are (1) to study the feasibility of using the available LIDAR datasets and aerial images over the area of the Chaophraya river basin (data of MOST and JICA) to create 3D city model and to determine the possible applications that could make use of the to-be-created products, and (2) to suggest appropriate applications that make use of 3D city model data to be developed for the case of the Eastern Economic Corridor (EEC) of Thailand which covers the Chonburi, Rayong, and Chachoengsao. In this study, vigorous studying and testing were conducted to achieve the objectives of this project. Sets of 3D city model were created over different characteristics of area such as 3D city model in dense urban areas and 3D city model in low dense urban areas. These 3D city models were to be used as examples for estimating tasks in order to answer questions listed in the objectives of this study. Additionally, the aforementioned 3D city models were created by different approaches in order to investigate and study on the pros and cons of each approach considering on different quality of the datasets used. Furthermore, the recommendations are made on the aspects of expected properties and qualities of raw LIDAR data and aerial images to be used for creating 3D city model in the area of the EEC of Thailand as well as the potential usages/applications those 3D city model. Finally, this study also suggests the approach of exploiting a platform that can facilitate variety usages of 3D city model in many applications by developing a mock-up software to demonstrate such idea.
