RISSpatial and Temporal Functional Requirements for an Extended Parcel-Based Land Information System
Publisher: American Society of Civil Engineers
Abstract: The nature of cadastral data in the United States is dynamic from a temporal perspective and measurement-based from a spatial perspective. The fundamental characteristics have been comparatively ignored in the development ...
Development and Implementation of Temporal Land Information System
Publisher: American Society of Civil Engineers
Abstract: An extended parcel-based land information system (LIS) was designed and implemented with respect to six additional major functional requirements: (1) incorporation of measurement data including measurement data retrieval, ...
Steepest Descent Method for Representing Spatially Correlated Uncertainty in GIS
Publisher: American Society of Civil Engineers
Abstract: All spatial data in a geographic information system (GIS) intrinsically contain uncertainty. Simulations could be used for many GIS applications in order to estimate confidence ranges of certain analyses and project ...
Parallel Partitioned Inverse Method for Least-Squares Adjustment
Publisher: American Society of Civil Engineers
Abstract: Parallel computing is undoubtedly the trend in numerical applications of highly intensive computation. There has been much related research and development on parallel computer architecture, algorithm design, and supplementary ...
Automated 3D Wireframe Modeling of Indoor Structures from Point Clouds Using Constrained Least-Squares Adjustment for As-Built BIM
Publisher: American Society of Civil Engineers
Abstract: Automated three-dimensional (3D) modeling of building interiors for an as-built building information model (BIM) incurs critical difficulties because of the complex design of indoor structures and a variety of clutter from ...
Automated 3D Wireframe Modeling of Indoor Structures from Point Clouds Using Constrained Least-Squares Adjustment for As-Built BIM

Automated and Efficient Method for Extraction of Tunnel Cross Sections Using Terrestrial Laser Scanned Data
Publisher: American Society of Civil Engineers
Abstract: An automated and efficient method for extraction of tunnel cross sections using terrestrial laser scanner (TLS) data is presented. In this process, a three-dimensional (3D) point cloud acquired from the TLS is projected ...
New Line Accuracy Assessment Methodology Using Nonlinear Least-Squares Estimation
Publisher: American Society of Civil Engineers
Abstract: This paper presents a novel line accuracy assessment technique by measuring the offsets of a typical measured line from the true reference line. These measurements are assumed to follow a Gaussian distribution. Buffers of ...
B-EagleV: Visualization of Big Point Cloud Datasets in Civil Engineering Using a Distributed Computing Solution
Publisher: ASCE
Abstract: Point cloud data (PCD) have attracted attention in many disciplines, including civil engineering. However, big PCD have posed great challenges for conventional approaches using a single computer. Although many published ...
