Datasets are used to store spatial objects of the same type and are one of the basic organizational units of spatial data. Currently, it supports various types such as point dataset, multipoint dataset, line dataset, region dataset, tabular dataset, network dataset, text dataset, route dataset, image/raster dataset, video dataset, and more.

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 encode type of datasets.

This chapter will introduce the following content:

• New Dataset: Introduces how to create various datasets such as point, line, region, text, CAD, and more.
• Sort Datasets: Introduces how to sort datasets.
• Save As/Delete/Close Dataset: Introduces how to save as, delete, or close datasets.
• Rename/Refresh Dataset: Introduces how to quickly rename and refresh datasets.
• Copy Dataset: Introduces how to copy a dataset.
• Data Export: Introduces how to export datasets.
• Recalculate Extent/Length/Perimeter and Area: Introduces how to update dataset bounds, length, and other information.
• Recalculate Extremes: Introduces how to update the extreme values in the dataset.
• Calculate Raster Statistics: Performs statistics on the raster values of a raster dataset.
• View Dataset Attributes: Views dataset-related information, including attributes, vector dataset or raster dataset, projection, and table structure, etc.
• Attribute management: Introduces the attribute management functions of vector datasets, including Range, Subtype, and Conditional Value management.
• Dataset Compression Encode Type: Details the encode type of datasets, helping users understand the characteristics and applicable scenarios of each encode type.
• CAD Dataset: Introduces how to display and edit CAD datasets.
• Dataset Group: Introduces how to create, cancel, export dataset groups, as well as how to move datasets to groups, and view the attributes of dataset groups.
