数字城市建设中地理信息数据处理方法研究

Research on Geographic Information Data Processing Method in Digital City Construction

为解决当前数字城市建设中存在地理信息数据适配度不足的问题,开展对其数据处理方法的设计研究。通过对DLG数据、DOM数据、三维(3D)图像数据、DEM数据等多种数据类型资料的采集,并对其进行相应的处理,从而提高数据质量。通过对比传统处理方法可以得出,新的处理方法处理后的数据质量更高,且具备更加理想的适配度。

In order to solve the problem of insufficient adaptability of geographic information data in the current digital city construction, the design and research of its data processing methods are carried out. The data quality is improved by collecting digital line graphic(DLG) data, digital orthophoto map(DOM) data, 3D image data, digital elevation model(DEM)data and other data types and processing them accordingly. Compared with the traditional processing methods, the new processing method has higher data quality and better adaptability.
