Create Replica
Function Description
Create Replica is used to replicate the data from the master version to the udbxFile Database, making it easier for field workers or contractors to edit and manipulate the data if they cannot connect to the internal network.
Function entrance
- Data tab-> Manage Replica group-> Create Replica.
- Data tab-> Manage Replica group-> Manage Replica button-> Add button.
Parameter Description
- Replica Data: Select the Datasource and Dataset for which Create Replica is required. By default, all Datasets under Datasource are checked. Therefore, it is necessary to check whether the checked Dataset can work without the internal network to ensure data security.
- Bounds Settings: Set the range of Replica Dataset, and crop the data in the main version to Replica Data according to this range. Default Range is the Whole Map range. Bounds Settings protects data by dividing it into multiple Zonal Data so that it can be distributed to different workers for editing. Support is set to Current Windows Bounds or Custom Bounds.
- Whole Map: Use the range of Whole Map as Tile Bounds, and the four text boxes at the bottom left and top right are used to display the set processing range;
- Current Windows: Use the range of Current Windows as the Tile Bounds.
- Custom Bounds: Click the Drop-down Button to select Select Object, Draw Rectangle or Custom Expression to set Tile Bounds.
- Select Object: The program switches to the current Map. Click an object as the processing range of the Tile. If multiple objects need to be selected, press and hold the Shift key to select objects in turn. After the selection is completed, click the right mouse button to end the selection state. Return to the Generate Map Tiles dialog box.
- Draw Rectangle: Switch the program to the current Map, use the mouse to Draw Rectangular Range in the window, click the right mouse button after drawing, end the selection status, and return to the Generate Map Tiles dialog box.
- Custom Expression: The program will pop up the SQL Expression dialog box, which supports the determination of Tile Bounds by setting the SQL Expression. The minimum Bounds of the expression Search Result is the Generate Tiles range.
- Copy, Paste: The program provides copy and paste buttons to copy Geographic Range. Click the paste button at the Range Settings that supports paste to set the left, lower, right, and upper values of Copy Bounds to the current range.
Caution: When Create Replica, it is recommended that the All Data set coordinate system be consistent. Or open all Datasets that require Create Replica to Map, start Dynamic Projection, and then perform Range Settings. To prevent some Dataset Bounds in the copy from being incorrect due to inconsistent coordinates. - Target Dataset: Set the storage information of Replica Data, including the following:
- Datasource: Set the Datasource stored in Replica Data. Currently, it is only supported to be stored in UDBXDatasource. You can create or select an Existing data source. Each udbxData source can only hold one Replica Data.
- Duplicate name: Set the name of the duplicate. Each duplicate has a unique name and cannot be the same as an existing duplicate.
- Description: The description can be set for the copy to facilitate the management of the copy.
Caution: - Currently, it is only supported to create and copy to UDBXFile Database. Only one copy
- per Datasource can be stored. The
- replica name is unique. Two replicas with the same name cannot exist in the same Datasource.
