Trawl fishing accumulated value obtaining method based on Beidou satellite data
The invention relates to a trawl fishing accumulated value obtaining method based on Beidou satellite data. In a formula defined in the specification, i, j, k represent a k ship position point of a net number of times j of a fishing vessel i in some grid, V[i, j, k] and V[i, j, k-1] represent in-tim...

| description | The invention relates to a trawl fishing accumulated value obtaining method based on Beidou satellite data. In a formula defined in the specification, i, j, k represent a k ship position point of a net number of times j of a fishing vessel i in some grid, V[i, j, k] and V[i, j, k-1] represent in-time speeds of two adjacent ship position points of the net number of times j of the fishing vessel i, and t[i, j, k] and t[i, j, k-1] represent time points of two adjacent ship positions points of the net number of times j of the fishing vessel i. When W[i] equals 1, L is accumulated mileage. When W[i] equals the power of the fishing vessel i, L is accumulated power mileage. When W[i] equals the net opening area of the fishing vessel i, L is the drainage volume. When W[i] equals the towing width of the bottom line and the net bag of the fishing vessel i, L is the sweeping area. The method concretely comprises the following steps of grouping states of a trawler; counting speeds of the trawler and determining the speed threshold; extracting the state of the trawler according to the speed threshold; and screening out a point where the trawler is in a fishing state according to the speed of the trawler, and calculating the trawl fishing accumulated value per unit grid. The invention can obtain a high temporal-spatial resolution, automatic and objective accumulated value. |
