Geographic space lattice-based radar detection data processing method

Abstract

The invention relates to a geographic space lattice-based radar detection data processing method, which comprises the following steps: (1) setting a rectangular geographic range to be detected; (2) in the rectangular geographic range, arranging coordinate points according to a line and row spacing rule under the requirement of resolution ratio to form a geographic space lattice; (3) acquiring an azimuth angle and a spherical distance of each point in the geographic space lattice relative to a radar; (4) clearing radar detection data corresponding to the current point to obtain a value of the point; (5) organizing values at the coordinate points in the lattice in a two-dimensional matrix storage structure, serializing data into binary data, and storing the binary data in a database; and (6) creating a data reading service interface, and calling radar product data stored in the database. The method has the advantages that a new way for processing, storing and sharing the radar detection data is provided, and a condition for counting and analyzing the radar detection data is also provided.

Description

Technical field [0001] The invention relates to the field of meteorological detection, in particular to a radar detection data processing method based on a geographical space lattice. Background technique [0002] With the development of detection technology, radar detection data has become more and more important and reliable weather detection data. However, radar product data is mostly in image format. With the development of GIS, how to match radar detection data with geographic information with precise location information for related data analysis is of great significance. At present, the "picture pulling" method is mostly adopted, that is, the boundary range of the radar detection data is first determined, and then the radar picture product data is forcibly "pulled" to the specified boundary range on the map. Although this method can achieve a certain matching effect, the position accuracy is often unsatisfactory, especially the image form of its data product records the c...

Problems solved by technology

Although this method can achieve a certain matching effect, the position accuracy is often unsatisfactory, especially the image form of the data product records the color RGB value, rather than the specific numerical information such as the intensity of the radar echo, and it is difficult to integrate it based on GIS Spatial Data Analysis of Geographic Information

And these product data are given colors according to a certain range of values, which greatly loses the accuracy of the values
