A dataset is used to store spatial objects of the same type and is one of the basic organizational units of SuperMap iDesktopX spatial data. Currently, various types of datasets are supported, including point datasets, line datasets, polygon datasets, attribute datasets, network datasets, composite datasets, text datasets, route datasets, image/raster datasets, and video datasets.

Dataset management includes operations such as creating, copying, deleting, closing, and renaming datasets, as well as sorting multiple datasets, viewing dataset properties, and setting the encoding format of datasets.

This section will introduce you to the following:

• Create Dataset: Describes how to create a variety of datasets, such as point, line, polygon, text, CAD, etc.
• Sort Datasets: Describes how to perform management operations such as copying, closing, renaming, deleting, and sorting datasets.
• Save/Delete/Close Dataset: Introduces how to save, delete, or close a dataset.
• Rename/Refresh Dataset: Describes how to quickly rename and refresh a dataset.
• Copy Dataset: Describes how to copy a dataset.
• Export Data: Describes how to export a dataset.
• Recalculate Range/Length/Perimeter and Area: Describes how to recalculate dataset bounds, length, and more.
• Recalculate Extremes: Describes how to recalculate dataset extreme information.
• Calculate Raster Values: Introduces how to count the grid value of the raster dataset.
• View Dataset Attributes: Introduces how to view information about the dataset, including properties, vector dataset or raster dataset, projection, and table structure.
• Dataset Compression Encoding Types: Introduces the encoding type of the dataset for users to understand the characteristics and applicability of each Encode Type.
• CAD Model Dataest: Describes how to display and edit a CAD dataset.
• Dataset Group: Describes how to create, cancel, and export dataset grouping, as well as how to move datasets to a group and view the dataset group properties.
