  • Investigating Semi-Automated Cadastral Boundaries Extraction from Airborne Laser Scanned Data

    • Authors: Luo, Xianghuan.;  Advisor: -;  Participants: - (2017)

  • Many developing countries have witnessed the urgent need of accelerating cadastral surveying processes. Previous studies found that large portions of cadastral boundaries coincide with visible physical objects, namely roads, fences, and building walls. This research explores the application of airborne laser scanning (ALS) techniques on cadastral surveys. A semi-automated workflow is developed to extract cadastral boundaries from an ALS point clouds. Firstly, a two-phased workflow was developed that focused on extracting digital representations of physical objects. In the automated extraction phase, after classifying points into semantic components, the outline of planar objects such ...

  • Quantifying the Overlap between Cadastral and Visual Boundaries:A Case Study from Vanuatu

    • Authors: Luo, Xianghuan.; Bennett, R.M.;  Advisor: -;  Participants: - (2017)

  • Cadastres are argued as an essential tool to support land tenure security. Low cadastral coverage in developing countries creates a driver for innovative methods to expedite the mapping processes. As a human construct, the morphology of parcel boundaries is a diverse and complex topic: there are limited generalized rules for identifying, describing, and classifying them. This paper studies both the institutional and spatial aspects of cadastral boundaries, in order to provide more contemporary knowledge about the morphology of cadastral boundaries. This study inspects the relationship between topographic objects and general boundaries in the case context of Port Vila, Vanuatu. Statist...
