The vector dataset attribute panel displays six sections: Dataset, Coordinate System, Vector, Attribute Table, Domain, and Subtype. Detailed descriptions are as follows:

Dataset

Click the Dataset item in the Properties panel to display attributes of the vector dataset, including basic info, dataset bounds, and description.

Basic Info

• Name: Displays the name of the dataset.
• Type: Displays the dataset type. For example, Point for point datasets and Line for line datasets.
• Table Name: Shows the name of the dataset's attribute table.
• Encode: Displays the compression encode type used for dataset storage.

Dataset Bounds

The Top and Bottom values in dataset bounds represent the maximum and minimum values along the Y-axis, while Left and Right indicate the minimum and maximum values along the X-axis. Units match the dataset's coordinate system.

• Update: Updates vector dataset bounds based on spatial object locations.
• Copy and Paste: Click Copy to copy current dataset bounds, or click Paste to apply clipboard-stored bounds info.

Dataset Description

Allows viewing and editing dataset metadata descriptions to facilitate understanding of data content, sources, and applications.

Coordinate System

Click the Coordinate System item in the Properties panel to display coordinate system information.

• Coordinate System: Shows the coordinate system of the vector dataset.
• Unit: Displays coordinate system units.
• Coordinate System Info: Provides detailed coordinate system descriptions.

For coordinate system toolbar functions, refer to Map Properties - Coordinate System.

Vector

Click the Vector item in the Properties panel to display vector information.

Vector Dataset

• Object Count: Displays total number of objects in the dataset.
• Charset: Shows dataset character set, modifiable via dropdown menu.
• Index Type: Displays spatial index type.
• Storage Mode: Indicates dataset storage method.
• Read-only: Sets dataset read-only status. Enabled state prohibits editing operations like adding, modifying, or deleting objects.

Tolerances

• Fuzzy: Sets minimum distance between nodes. Nodes within this tolerance merge during topology processing. Unit matches dataset's coordinate system.
• Short Dangle: Determines dangling lines shorter than this tolerance as overshoots, removable during topology processing. Unit matches dataset's coordinate system.
• Long Dangle: Controls extension of long dangles. Lines within this tolerance from nodes can be extended during topology processing. Unit matches dataset's coordinate system.
• Grain: Controls node spacing on curves/arcs during parametric-to-linear conversion. Unit matches dataset's coordinate system.
• Polygon Tolerance: Defines minimum polygon area-to-perimeter ratio for sliver polygon identification during topology processing.

Vector Pyramid

Vector pyramids significantly improve display efficiency for massive data at small scales.

Supported only for point/line/region datasets in UDB/UDBX datasources.

Attribute Structure

Click the Attribute Structure item to display selected vector dataset's table structure in tabular format.

Each row represents a field with the following columns:

• ID: Row sequence number.
• Name: Field name (immutable after creation). Naming rules: 1) Start with letter/Chinese character; 2) 1-30 bytes; 3) No special characters; 4) Avoid database reserved keywords.
• Alias: Display name for fields in attribute tables.
• Type: Field value type, modifiable via cell editing.
• Length: Maximum value length (applicable only to Text/Wide Char types).
• Default: Default field value for new records.
• Required: Mandatory field status (values cannot be empty).

Use toolbar buttons above the attribute structure table for operations:

• Add: Creates new fields.
• Modify: Edit selected cell (click button or double-click cell).
• Delete: Removes selected field(s).
• Hyperlink: Converts Text/Wide Char fields to hyperlinks.
• Apply: Commits structural changes (add/delete/modify fields).
• Keep backup data after modifying fields: When enabled, creates backup dataset (e.g., BackUp_Newpoint) preserving pre-modification attributes.

Domain

Click the Domain item to display field domain information, including alias, type, and domain details. Use toolbar buttons to create/manage domains.

Subtype

Click the Subtype item to view subtype information, including subtype field, default subtype, and subtype details.
