Based on the analysis on characteristics of resources and environment data, taking some Chinese resources and environment data as sample, the paper describes the method and process of data integration. Seven steps of resources and environment data integration are included: decomposing of integration application, dataset management, generation and usage of metadata, multi-scale data processing, data quality evaluation and controlling, data integration processing, and evaluation of data integration.
