Design and realization of meteorological elements retrieval and graphics display module based on ArcGIS engine

This study is sponsored by the project “intelligent interactive service system” from national climate center (NMC) of China Meteorological Administration (CMA). Using ArcGIS Engine (AE) developer kit 9.2 as the core development software and C# as programming language as well as Oracle as database, the meteorological elements retrieval and graphics display modules based on C/S model were designed and developed. To a certain extent, the module overcomes the disadvantage that the meteorological elements retrieval and graphic display does not satisfy users’ dynamic needs by the combination of external configuration information and reflection mechanisms in Microsoft .NET framework. The module realizes the function drawing the graphics result of meteorological elements retrieval automatically, which can provide the scientific basis for the decision-making service of government departments.
