Abstract

Structurally describing the portrayal-related information by using a standalone Digital Cartographic Model on top of a Digital Landscape Model has been proved applicable and beneficial for 2D mapping but has not yet been applied to 3D cadastre. This study, therefore, evaluates the applicability of digital cartographic model and the corresponding visualization pipeline for 3D cadastre in the context of Chinese urban cadastre. This research starts by identifying the requirements and design features of 3D cadastre mapping through a literature review and interviews with users and cartographers. Addressing the limitations of the existing general-purpose models, this paper proposes an ad hoc 3D cadastre digital cartographic model. The main developments of the proposed model are the inclusion of 3D content modeling, the support of the compound 3D symbols, and the introduction of the semantic transformation. The proposed model is then embedded into three parts of the cadastre visualization pipeline: the symbolic rule design, graphic content creation, and scene dissemination. The empirical result of qualitative proof-of-concept user tests supports that the proposed visualization pipeline is applicable and yields promising visualization results. The digital cartographic model-based visualization pipeline is a novel 3D cadastre mapping paradigm that facilitates designing, producing, sharing, and administrating.

Highlights

By evaluating current general-purpose digital cartographic model (DCM) with respect to the 3D cadastre mapping design features, we found that the existing general-purpose DCMs, even those proposed for 3D visualization, could not fulfill the needs of 3D cadastre mapping
The research described in this paper addresses the interoperability problem of 3D cadastre mapping by providing a 3D digital cartographic model solution with a new model design, two supporting applications, a DCM-based visualization pipeline, and the corresponding applicability evaluation with potential cartographers and readers
The empirical result of qualitative proof-of-concept user tests shows that the proposed DCM and the DCM-centered visualization pipeline is applicable and beneficial to 3D cadastre mapping practices

Summary

Introduction

As 3D cadastre mapping often deals with congregated scenarios and complex legal realities, fine-tuning the cartographic enrichment is key to ensuring a usable mapping result. Addressing this topic, plenty of mapping and visualization designs have been proposed according to the discoveries about the user’s visual capability, visual task, cartographic enrichment, prototype implementation, and the usability of the 3D cadastre visualization [4,10,11]
