Concept of Dataset
Dataset is one of the fundamental organizational units of spatial data in SuperMap GIS, serving as the smallest unit for data organization. Datasets can be visualized as layers in maps. Visual editing of datasets is also achieved through maps, such as modifying the spatial positions and shapes of geometries in edit data mode or acquiring new datasets through vectorization.
All datasets opened in the workspace are stored in data sources and exist independently from the workspace.
For raster and image datasets, they are displayed in maps as images based on their stored pixel values.
A data source can contain multiple datasets of various types. You can manage datasets within a data source through the data source in the workspace, including creating datasets, importing data from other sources as datasets, and performing other operations.
