Object Trace History is different from the Historical Moment feature. Object Trace History targets objects, while Historical Moment targets the entire dataset. Object Trace History includes two features: Object Historical Change and Delete History. Historical Change refers to the trace history of current feature editing, and historical data will be stored in object properties; Delete History is the trace history of deleted objects, and historical data is stored in dataset properties.
Historical Change
When objects in a versioned dataset change, the change time will be recorded in object properties. The operations for Historical Change are as follows:
- Select the edited object in the map, and choose the Properties item from its context menu. Then, you can view the changes record in the Historical Change item of the object properties panel. The change record list includes historical moment information and user info.
- Click on one of the histories, and the object's spatial position at that moment will be displayed in gray on the map.
- If it is a property change, you can right-click and select the Attribute Comparison item to view the attribute changes.
- If a certain record in Historical Change contains the correct information, you can use the Recover Object button in the history context menu to restore the data information of that historical moment.
Note:After recovering the object, you need to manually delete the object before recovery and keep only the recovered object.
Delete History
For mistakenly deleted objects, you can retrieve them through Delete History. The specific operations are as follows:
- In the workspace manager, select the Properties item from the dataset context menu to open the dataset attribute panel. The Delete History item in the panel records all deleted objects in this dataset, including Object ID, delete moment, and user info.
- Find the mistakenly deleted object record by Object ID or delete moment. After selecting the record, the object's spatial position at that moment will be displayed in gray on the map.
- After finding the mistakenly deleted object record, select the Recover Object button from the context menu to retrieve the mistakenly deleted object.
