The Construction Of Environmental Archaeology Database Based On Aerial Survey Data And 3D Visualization Method

As an emerging discipline, environmental archaeology introduces new means in research methods. UAV(Unmanned Aerial Vehicle) becomes a new method of obtaining data and has great potential in environmental archaeology as a basic geographic information collection method. However, a set of effective management methods is needed for years of archaeological research and achievements. The construction for environmental archaeology database provides a unified platform for its management of data and achievements, meeting the demand of environment archaeology research in different spatial and temporal scale.Based on the UAV aerial data as a starting point, in view of data structure of Geodatabase, meeting the unified description in the relationship between site information and space, this paper enables researchers to comparatively analyze the related environmental archaeological information under a unified system, and explores its inner connection between time and space. The basic data base set up the basic date base, thematic data and relational data, GaoFen images, Quick Bird image and UAV aerial data in the form of raster datasets stored within the database; Basic data include administrative boundary of the study area, residential areas, road traffic and the cloud point data and other basic geographic information; Project data set is the collection of environmental archaeology research field data; Relations dataset build relationships between each attribute tables; Based on Sites Table, relationship between Sites and other attribute tables through the Code_Site is built. Between Profiles Table and Sporopollens Table, relationship by Code_ Profiles, guaranteeing to form an organic whole association between each of the data inside the database is built.Based on environmental archaeology database, taking Erdaoliang Sites of Nihewan for example, this paper explores the paleoenvironment reconstruction of 3D visualization method, presenting the different dimensions based on large scale, mesoscale and small scale from two aspects of internal force and external force. Based on environmental archaeology database, rebuilding the paleozoologic, paleobotany and other natural factors in the paleoenvironment, completing the reconstruction of the paleoenvironment.Before rebuilding the environmental archaeology database, this paper puts forward the function of UAV aerial survey data in different study stages of environmental archaeology. Based on the analyzing the characteristics of UAV aerial survey data, this study defines that UAV aerial survey can support small-scale environmental archaeology research’s demand for basic geographic information combined with derived data and other multi-source data, the paper puts forward UAV aerial value system in environment archaeological. In this system, UAV aerial data is acted as the main part and the core point. In this study, we systematically summarize and abstract the important roles that UAV aerial survey data plays in various stages of environmental archaeology. Designing, planning,spatial integration with related base before inspection, The intelligent measurement and information management in the investigation, point distribution and spatial relations, site domain, site horizon calculation analysis in the process of site horizon calculation analysis. Unmanned aerial data in environmental value analysis system provides System theory and thinking for carrying out the environmental archaeology on the perspective of time and space.
