Abstract

Abstract. The preservation of traditional settlements plays an indispensable part in the field of heritage preservation. The traditional settlements, definitely with cumulative developmental layers, vary in elements and involving numerous stakeholders; therefore, preservation objects and methods are quite complicated. The traditional heritage investigating and recording tools, such as manual mapping, photographing and field reconnaissance, which have exposed many limitations and deficiencies in the actual work, have defects to meet the requirements of settlement heritage preservation projects. This paper describes the process of applying of modern digital heritage recording and investigation technology (mobile GIS and 3D laser scanning technology) in the preservation of Wenming historical and cultural blocks in Kunming and argues that Mobile GIS and 3D laser scanning technology are capable of producing a complete and efficient workflow, as well as providing fundamental technical support for heritage preservation work. Through the research, this paper draws a conclusion that the advantages of the workflow including: (1) accurate and convenient recording, (2) efficient comprehensive spatial analysing, and (3) better integrating protection planning with the later dynamic monitoring and management. Additionally, the author forecasts the prospects of the application of this workflow in the preservation and utilization of settlement heritage.

Highlights

  • The preservation of traditional settlements plays an indispensable part in the field of heritage preservation

  • The preserving and supervising problems reveal in Wenming historical and cultural blocks, which are caused by the out-dated recording technology, is the In China, where there is an ancient civilization of five thousand microcosm of historical and cultural blocks across China

  • Ever The information recording of historical and cultural block can since 1950s, Chinese government has gradually founded a be typically classified into two categories: (1) basic block comprehensive heritage preservation system, which refers to information, include the style, quality, history, property right different types of cultural heritages, such as immovable heritage, and so on, most of which are recorded manually in paper historic cities, historic towns and historical blocks and so on. document; (2) surface and structure information of architecture, (Ruan, 1999)

Summary

INTRODUCTION

Problems reveal in Wenming historical and cultural blocks, which are caused by the out-dated recording technology, is the. Historical and cultural block, as an important aspect of Chinese have exposed many limitations and deficiencies in the actual settlements preservation, is an essential existence of urban work. 2.1 Low efficiency of basic information recording with omissions and errors of them are experiencing poor preservation, decayed function, outdated facilities and other problems because of social vicissitudes and urban function changes. Because the information recording on the field is by the means of paper, much work is needed to sort out data and match drawings manually. The outcomes of information recording are only CAD drawings, Microsoft Word documents and paper documents, but not consolidated digital
