Data processing method and device

The invention provides a data processing method and device. The data processing method comprises the steps of obtaining a first recognition model, wherein the first identification model is a model established based on first observation data and an ice water classification result corresponding to the first observation data, and the first observation data is observation data acquired by a satellite in the previous day; acquiring second observation data, wherein the second observation data is observation data acquired by the satellite on the day; and determining an ice water classification result corresponding to the second observation data according to the first identification model and the second observation data. The method is used for improving the accuracy, timeliness and efficiency of sea ice identification. 本申请提供一种数据处理方法及装置。数据处理方法，包括：获取第一识别模型；所述第一识别模型为基于第一观测数据和所述第一观测数据对应的冰水分类结果建立的模型；所述第一观测数据为卫星前一日采集到的观测数据；获取第二观测数据；所述第二观测数据为所述卫星当日采集到的观测数据；根据所述第一识别模型和所述第二观测数据确定所述第二观测数据对应的冰水分类结果。该方法用以提高海冰识别的准确度、时效性和效率。
