Dynamic drawing method and system for weather and water conservancy color spot diagram

Abstract

The invention discloses a dynamic drawing method and system for a weather and water conservancy color spot diagram, and the method comprises the steps: obtaining corresponding first lattice point data in response to a drawing parameter and a drawing range selected by a user; according to picture pixels selected by a user, performing interpolation processing on the first lattice point data through a bilinear interpolation method to obtain corresponding second lattice point data; and according to the drawing range and the second lattice point data, obtaining a corresponding meteorological water conservancy color spot diagram. The first lattice point data corresponding to the selected drawing parameters and the drawing range is obtained, bilinear interpolation processing is carried out on the first lattice point data, the data encryption effect is achieved, distortion of the drawn meteorological water conservancy color spot diagram is prevented, the drawing precision of the meteorological water conservancy color spot diagram is improved, and the drawing efficiency of the meteorological water conservancy color spot diagram is improved. Therefore, a predictor can carry out more accurate analysis according to the weather and water conservancy color spot diagram.

Description

technical field [0001] The invention relates to the field of meteorological and water conservancy color speckle drawing, in particular to a dynamic drawing method and system for meteorological and water conservancy color speckles. Background technique [0002] Meteorological and water conservancy color pattern is a form of expression of meteorological elements such as temperature and precipitation. Through the meteorological and water conservancy color pattern, people can quickly understand the meteorological conditions in different regions and at different times. In addition, specific weather conditions will have a serious impact on forestry, agriculture, and water conservancy. Combined with the data information and professional knowledge services presented by the meteorological and water conservancy color spot map, it can provide effective operation guidance for industries in various fields. [0003] However, the display of meteorological and water conservancy color patter...
