| 中文摘要: |
| 依据自然资源资产大数据差异图斑的变更类型，归纳总结了差异图斑的提取内容，并利用FME软件构建出不同时间节点上差异图斑的提取模型，实现了一键式提取，从而形成一整套差异图斑提取的技术流程。该研究对于拓展自然资源资产大数据潜在应用领域，促进多源数据联合监测，提高资源监测精度、效率和可靠性具有实际意义。 |
| 英文摘要: |
| According to the change types of the difference patches in the large data of natural resources assets, the extraction contents of the difference patches are summarized. The FME software is used to construct the extraction model of the difference patches at different time nodes, and the one-click extraction is realized, thus forming a complete set of technical processes for the extraction of difference patches. This research is of practical significance for expanding the potential application fields of natural resources asset big data, promoting joint monitoring of multi-source data, and improving resource monitoring accuracy, efficiency and reliability. |
