为了弥补行政区尺度的城市自然灾害应急救援能力评价精度不足问题,本文提出了基于网格尺度的城市自然灾害应急救援能力评价方法。网格具有栅格数据的显示形式,同时又有矢量数据的属性信息,通过对数据网格化使矢量数据更加详细化,从而提高评价精度。实现了基于网格尺度的城市自然灾害应急救援能力评价,以期为城市自然灾害应急救援工作提供服务。
In order to make up for the low accuracy of the assessment of urban natural disaster emergency rescue capacity under the administrative district scale, this paper proposes the assessment methods based on the grid scale. The grid has the display form of raster data and vector data. Through the data grid, the vector data is more detailed, so that it can improve the evaluation accuracy. The assessment of urban natural disaster emergency rescue capability under the grid scale is realized, hoping to provide services for the urban natural disaster emergency rescue work.
