Abstract: A method and device for optimized scheduling of massive transport vehicles during flood disasters, relating to the field of transportation resource scheduling is provided. The method includes determining flood inundation ranges during various time periods of a flood based on watershed precipitation and river cross-section structural data and marking accessible roads within a flood-affected area with double truncation. A road information matrix and a resettlement zone information matrix is determined and model information and location information of transport vehicles within the flood-affected area are also determined. A transport vehicle dataset is also determined.

Abstract: Provided are a dynamic mutual feedback-based method for property placement in flood evacuation, a product, a medium, and a device. The method includes: performing calculations using GIS and a two-dimensional hydrodynamic model, to generate a flood inundation map, and delineating village property risk zones and safety zones; constructing a road network topology, and performing road segment accessibility analysis based on the flood inundation map, to form an accessible road network topology; determining a property placement mode for a property risk zone of a current village; if the property placement mode is in-zone, placing properties in the property risk zone of the current village into a placement site of the current village; if the property placement mode is transfer, based on rules of grid-based transfer, classified transport, and dedicated-area placement, generating a feasible transfer placement route set; iteratively calculating paths to determine an optimal flood evacuation route.

Abstract: A method and device for determining a flood-diversion strategy of a flood storage and detention basin based on a balanced perspective is provided. The method includes determining excess flood peaks and excess flood amounts of middle and downstream main streams in a preset time period after scheduling and enabling of a reservoir group in each river section. A correlation map between a flood-diversion amount and a flood-diversion water-level reduction value under each set flood-diversion parameter combination is then constructed. Enabling priorities and flood-diversion volumes for all flood storage and detention basins in all river sections are determined. A cumulative flood-diversion volume of each flood storage and detention basin is also determined. A flood storage and detention basin-enabling knowledge map is constructed and a plurality of flood-diversion plans are determined. A flood-diversion plan from the plurality of flood-diversion plans is then selected as a target plan to allow flood diversion.

Abstract: A drone-based mobile precision surveying method for terrestrial terrain, a device, a medium, and a product are provided. The method includes: determining regional terrain data of a target area based on three-dimensional coordinate data of image control points in the target area and position information of a drone by using a real-time dynamic differential positioning technology; correcting regional terrain data of a signal-deficient area in the target area based on the three-dimensional coordinate data of the image control points and the regional terrain data by using the real-time dynamic differential positioning technology, to obtain corrected regional terrain data of the signal-deficient area; and integrating regional terrain data of a signal-covered area in the target area and the corrected regional terrain data of the signal-deficient area by using a Geographic Information System (GIS) integration method to obtain corrected regional terrain data of the target area.
