Embodiment 1

[0080] This embodiment uses the lower reaches of the Jinsha River as the research area to illustrate the technical solution. 38 rainfall stations established before 2009 are taken as existing stations, and the new satellite rain radar is taken into account on the ground coverage. The 31 ground rainfall stations were optimized and compared with the actual layout to verify the effectiveness of this method. The lower reaches of the Jinsha River is located in the upper reaches of the Yangtze River, with a basin area of ​​135473km 2 With abundant rainfall and frequent heavy rains in the rainy season, its rainfall monitoring is of great significance to hydrometeorology and flood forecasting in the middle and lower reaches of the Yangtze River. There are 69 rainfall stations in the lower reaches of the Jinsha River, of which 38 were established before 2009, and the other 31 were newly added in 2009. According to the results of the 2011 Yangtze River Basin Hydrological Station Network ...

Abstract

The invention discloses a ground precipitation station layout optimization method and device, and relates to the technical field of smart city geographic information services. The method comprises the steps that the mesh dividing information and the time segmentation information of a target monitoring area are obtained; the effective coverage of precipitation observation satellites and the effective coverage of ground precipitation stations are obtained according to covering information of the precipitation observation satellites and covering information of the ground precipitation stations; a ground precipitation station layout limited candidate point set is obtained according to topographic information of the target monitoring area and standard covering information of the ground precipitation stations; a maximum continuous-time covering model is obtained; and a precipitation station layout optimization scheme is determined according to the maximum continuous-time covering model. The method and device are used for solving the technical problems that in the prior art, the ground precipitation stations and the precipitation observation satellites often exert effects independently, the influences of satellite covering on layout of the ground precipitation stations are not taken into account, and the requirements of cooperative observation of a hydrological sensor network and resource optimization configuration cannot be met.

Description

Technical field [0001] The invention relates to the technical field of geographic information services for smart cities, in particular to a method and device for optimizing the layout of ground rainfall stations. Background technique [0002] With the continuous development of earth observation technology, hydrological monitoring has evolved from a traditional single ground station network to a new stage of integrated space-earth observation sensor network. Rainfall is a basic component of the earth's water cycle and has important hydrological significance and monitoring value. The existing technologies mainly use ground observation and satellite remote sensing as the main technical means for sensor network rainfall monitoring. [0003] In the prior art, due to the limitation of imaging mechanism and revisit period, remote sensing satellite earth observation has the characteristics of continuous space and discontinuous time, and its coverage is a strip-shaped area, which can be cal...
