Vector Dataset Properties Window

If one or more vector datasets are selected in the Workspace Manager, the Dataset Attribute panel will display six sections: Dataset, Coordinate System, Vector, Attribute Table, Range, and Subtype. Each section shows information about the selected dataset in the Properties panel. The following details explain specific contents:

Dataset

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

Basic Info:

  • Dataset Name: Displays the name of the vector dataset.
  • Dataset Type: Displays the type of the vector dataset.
  • Table: Displays the name of the attribute table associated with the vector dataset.
  • Encoding: Shows the encode type used for dataset storage compression. For details, see: Dataset Compression Encode Type.

Dataset Bounds:

The top and bottom values represent boundaries along the Y-axis ("Y="), while the left and right values represent boundaries along the X-axis ("X="). Units match the dataset's coordinate system. Dataset bounds support update, copy, and paste operations:

  • Update: Recalculate bounds based on spatial object positions. See Update Vector Dataset Bounds.
  • Copy and Paste: Click Copy to copy current bounds, or Paste to apply copied left, bottom, right, and top values.

Dataset Description: Shows the dataset description, which users can edit.

Coordinate System

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

  • Coordinate System: Shows the dataset's coordinate system.
  • Unit: Displays the distance unit of the vector dataset.
  • Coordinate System Info: Provides detailed projection description.

Toolbar functions for coordinate system:

  • Reset Coordinate System: Choose from dropdown or click More to open the Coordinate System Settings dialog. For setup methods, see Projection Settings Window.
  • Copy Coordinate System: Opens the Copy Coordinate System dialog to copy projections from:
    • Existing datasources in the current workspace.
    • Existing datasets in the current workspace.
  • Export Coordinate System: Exports projection to an XML file.
  • Import Coordinate System: Imports projection from an XML file.
  • Project: Opens the Project dialog to convert the dataset's projection. See Project for steps.

Vector

Click the Vector option in the Properties panel to view vector dataset details.

Vector Dataset:

  • Object Count: Total number of spatial objects.
  • Charset: Displays the character set. Select from dropdown to change. See Charset List.
  • Index Type: Shows spatial index type. See Index Type.
  • Storage Format: WKB (Well-Known Binary) for spatial data or SuperMap's custom format.
  • Has M Values: Indicates whether coordinates include measurement values. No or Yes. See New Dataset.
  • Read-only: Checkbox indicates if the dataset is read-only. Editing operations are disabled when checked.

Tolerances:

  • Fuzzy: Minimum distance between nodes. Nodes within this distance merge during topology processing.
  • Short Dangle: Threshold to identify dangling lines as overshoots if shorter than this value.
  • Long Dangle: Threshold to extend undershoots to nearby lines during topology processing.
  • Grain: Controls node spacing when converting parametric curves to lines.
  • Minimum Polygon: Sliver polygon tolerance. Polygons with area-perimeter ratio below this are removed.

Vector Pyramid:

Vector pyramids significantly improve display efficiency for large datasets at small scales. Supported formats: UDBX, PostGIS, Yukon point/line/region datasets. See Create Vector Pyramid.

Attribute Structure

Click Attribute Structure in the Properties panel to display the table structure of selected datasets in grid format.

Each row represents a field, with columns showing:

Notes:

Field length settings are invalid when creating long binary type fields.

  • ID: Row index 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 reserved keywords. See Database Reserved Keywords.
  • Alias: Display name for the field.
  • Type: Data type. Modifiable for PostgreSQL, OraclePlus, SQLServer, DMPlus, MySQL, PostGIS datasets. See Data Types and Modification.
  • Length: Maximum value length (applicable to Text and Wide Char types).
  • Default Value: Initial value for new records.
  • Required: Indicates if the field must contain values.

Toolbar functions above the attribute table:

  • Add: Create new field.
  • Modify: Double-click or select cell and click to edit.
  • Delete: Remove selected field(s).
  • Hyperlink: Set text/wide char fields as hyperlinks. See Hyperlink.
  • Apply: Save all structural changes.
  • Keep Backup Data After Modifying Fields: When checked, creates backup datasets (e.g., BackUp_Newpoint) preserving pre-modified attributes.

Range

Click Range in the Properties panel to view domain information for dataset fields, including aliases, types, and specific ranges. Use toolbar buttons to add/manage domains.

Subtype

Click Subtype in the Properties panel to manage subtype details: subtype field, default subtype, and subtype definitions.
