Embodiment Construction

[0059] A new earthquake catalog persistence and visualization method according to the present invention includes four basic steps: 1. Establish earthquake catalog metadata; 2. Set query conditions, and determine corresponding earthquake visualization expression resources according to the query results; 3. Encapsulate and store query results and visual expression resources in KML or KMZ data packages; 4. Use existing 3D geographic information system software to read, manage and control the packaged KML or KMZ data packages to complete the visualization of packaged earthquake catalogs process.

[0060] The specific implementation process is as follows:

[0061] Step 1. Summarize the information of previous earthquake events in the computer, and form the required metadata of the earthquake catalog with longitude, latitude, time of occurrence and magnitude as the basic information. The measurement unit of each metadata record is consistent.

[0062] Among them, the metadata of ea...

Abstract

The invention discloses a novel earthquake catalogue persistence and visualization method. The method comprises four basic steps of: 1, establishing earthquake catalogue metadata; 2, according to a query condition, determining corresponding earthquake visualization expression resources; 3, packaging a visualization earthquake catalogue mapping subset and the visualization expression resources in a KML or KMZ data package; and 4, reading, managing and controlling the packaged KML or KMZ data package by utilizing three-dimensional geographic information system software, thereby finishing the packaged earthquake catalogue visualization process. According to the method, the earthquake visualization expression resources are enriched, the visualization effect is intuitive, definite, clear and accurate, the packaged data interaction is realized by utilizing the three-dimensional geographic information system software, the visualization efficiency is improved, the space-time distribution law visualization of a large amount of earthquake catalogues is realized, and the convenience is provided for further discovering space-time evolution regularities of earthquake activities.

Description

technical field [0001] The invention relates to a computer visualization technology method, in particular to a novel earthquake catalog persistence and visualization method for describing the time-space migration law of seismic activity in the visualization of earthquake scientific data. Background technique [0002] Seismic activity, as a natural disaster, threatens the safety of human life and property and exists for a long time. Since seismic activity occurs deep in the earth's crust, the mystery of earthquake occurrence has not been fully revealed in science. Therefore, the study of time-space migration activities of historical earthquakes has become an effective and important way to understand the laws of earthquake occurrence. [0003] The data volume describing the temporal and spatial intensity distribution of earthquakes is generally called "earthquake catalog". Every earthquake event that has occurred and recorded will be written into the earthquake catalog with d...
