为有效管理地质灾害数据,构建2类数据模型并整合ESR1的Geodatabase数据模型和关系数据库(RDBMS)来存储和管理复杂的区域公路地质灾害数据,确保数据对象的精度与完整性。一类是区域公路地质灾害数据模型,包括地理与社会经济要素数据集、地形与岩性构造要素数据集、水文与气象监测要素数据集、灾害信息与分布要素数据集、群测群防监测网要素数据集及分析与评价结果要素数据集;另一类是公路地质灾害单体工点数据模型,主要包括监测布置网要素数据集、基础属性数据、监测数据和分析数据。采用ArcEngine开发了ArcHgddms来创建这2种公路地质灾害数据模型,并建立了包含空间数据(如矢量数据和栅格数据)和属性数据的公路地质灾害数据库。
To effectively manage geohazard data, two types of data models are constructed and integrated into ESR1’s Geodatabase data model and relational database (RDBMS) to store and manage complex regional road geological hazard data to ensure the accuracy and completeness of data objects. One is the regional highway geological hazard data model, which includes the data set of geography and socio-economic factors, topographic and lithological structural elements dataset, hydrological and meteorological monitoring elements dataset, disaster information and distribution elements dataset, Element dataset and element dataset of analysis and evaluation result; the other is data model of highway single site of geological disasters, which mainly includes element data set of monitoring arrangement network, basic attribute data, monitoring data and analysis data. ArcHgddms has been developed with ArcEngine to create these two types of highway geological hazard data models and to establish a database of road geological hazards containing spatial data such as vector data and raster data and attribute data.
