Dataset group is used to manage multiple datasets within the same data source, facilitating data display and lookup. For example, datasets related to roads and rivers in the data source can be stored in road and river groups respectively. When searching for a specific road dataset, you only need to look under the road group. Additionally, when opening a group to the map, all datasets within the group are opened by default.
When using dataset groups, note the following:
- Dataset groups do not support setting coordinate systems, but can store datasets with different coordinate systems.
- A dataset group can store datasets of different types, but within the same data source, a dataset can only belong to one group.
- Group nesting is supported, meaning subgroups can exist within a group.
SuperMap ImageX Pro Starting from the 2025 version, the dataset group functionality is provided.
New Dataset Group
- In the context menu of an existing data source, click New.
- A new dataset group named "DatasetGroup" will be added to the data source. You can change the name of the dataset group as needed. Within the same data source, the dataset group name must be unique, and the group name should consist of Chinese characters, letters, numbers, and underscores, but cannot start with a number or underscore.
Copy Dataset Group
Copying a dataset group will copy the datasets and subgroups under it together, supporting copying within the same data source or across data sources.
- Select one or more dataset groups, then choose Copy in the context menu (or use the Ctrl+C shortcut).
- Select the target data source, then use the Ctrl+V shortcut to copy the selected dataset groups to the specified target data source.
If copying to a group, choose Paste in the context menu of the target group (or use the Ctrl+V shortcut) to copy the selected dataset groups to the specified target dataset group.
Note:
If there are groups or datasets with the same name in the target data source or dataset group, the same-named group or dataset name will have "_n" appended by default. n represents a number; the second same name appends "_1", the third "_2", and so on.
Move to group
Supports moving single or multiple datasets/groups to the target group. When moving a group, the datasets within it will also be moved, and moving groups is only supported via dragging.
- Select single or multiple datasets in the data source.
- In the context menu, select Move to group and choose the target group name to complete the dataset move operation.
Note:
- When dataset groups exist in the current data source, the Move to group function is available and only supports moving to groups within the current data source.
- Dragging a dataset or group to the target group within the current data source performs a move operation.
- If dragging a dataset or group across data sources to the target group, it performs a copy operation.
Export Dataset Group
Supports exporting dataset groups to FileGDB format files. A dataset group corresponds to a feature dataset in FileGDB. Since feature datasets have restrictions on data types, projections, etc., for the feature classes they contain, datasets in the group must meet the following conditions to export all datasets in the group to the feature dataset in the FileGDB format file:
- Dataset types include only 2D/3D point, line, and region datasets. Tabular datasets can be exported to FileGDB but not to the corresponding feature dataset; other data types are not supported for export.
- Datasets must have consistent coordinate systems. If coordinate systems are inconsistent, only datasets with the same coordinate system as the first dataset will be exported.
- There should be no subgroups in the group. If subgroups exist, you need to manually add datasets from the subgroups to the export list, and after export, the subgroups will lose their hierarchical relationship with the parent group.
Steps are as follows:
- Select the dataset group to be exported, right-click and choose Export.
- In the Data Export dialog, set the parameters for exporting data. For details, refer to Export FileGDB.
Import Dataset Group
Supports importing feature datasets from FileGDB as dataset groups.
- In the context menu of an opened data source, select Import Dataset.
- In the Data Import dialog, from the Select Folder dropdown menu, choose File GeoDatabase Vector File, then in the popped-up Browse Folder dialog, select the FileGDB folder to import.
- In the Data Import dialog, set the parameter information. For details, refer to Import FileGDB Data.
View Dataset Group Properties
- In the workspace manager, in the context menu of a dataset group, select Properties.
- The properties panel on the right will display attributes of the dataset group, including:
- Name: Displays the name of the dataset group.
- Number of Datasets: Displays the total number of datasets under this dataset group.
- Dataset Group Description: Displays and allows modification of the description of the dataset group, facilitating others' understanding of it.
Cancel Dataset Group
After canceling a dataset group, the subgroups or datasets within it will belong to the parent group.
- Select the dataset group for which you want to cancel the group.
- Right-click and choose Cancel Group to complete the operation of canceling the dataset group.
