<p>PROBLEM TO BE SOLVED: To solve a problem that information exceeding a displayed image data is not displayed because the image data is not correlated with meteorological data of original data although the image data are prepared preliminarily to enhance responsiveness for displaying a meteorological chart. SOLUTION: A projection, a reference latitude, a reference longitude, and a contraction scale of information required for preparation of the meteorological chart are registered preliminarily in an environment table. The meteorological data received when the meteorological data are received are stored in a meteorological DB. Then, processing for the preparation of the meteorological chart is carried out referring to the environment table, and stored accumulatedly as the image data in an image DB. The accumulated image data are displayed, a position on a map is determined in the displayed image data based on a coordinate value on an image assigned by an operator and the information registered in the environment table, a point (observation point in a observation data, or lattice point in a lattice point data) included within a specified range is used as a point required by the operator based on the position, meteorological information as to the point is extracted from the meteorological DB stored when the meteorological data are received, and are displayed after worked into a format in response to a request of the operator.</p> |
