Create Editable Chart Group

Feature Description

To produce a new nautical chart, you need to create a new editable chart dataset group. After successful creation, the corresponding dataset group will only contain the information entered during creation.

Steps

This example demonstrates how to create a CN5X0000 chart dataset group in the Chart datasource:

  1.  In Workspace Manager, right-click the Chart datasource node and select New Dataset... -> Editable Chart Group..., or click Chart Tab-> Chart Data Management group -> New Group to open the Create Editable Chart Group dialog. Configure the following parameters:
    • Datasources: Click the drop-down button to select the Chart datasource for storing the chart dataset group.
    • Data Standard: Default is S-57(3.1) (IHO November 2000 release). Can switch to CJ-57(JTS 195-3-2019) (China's Inland Electronic Navigation Chart Specification released August 2019).
    • Signature Sequence: Specify FIDN for the group. Click the drop-down button to select a signature sequence. If not created, click to create signature sequence.
    • Feature Identifier Distinguishing Number (FIDS): Essential part of FOID. Set between 1-65534 (e.g., 1).
    Create Editable Chart Group: Step 1
  2. After parameter settings, click Next to set layer bounds. Input longitude/latitude coordinates for NW/SE corners in Left, Bottom, Right, Top fields (e.g., Left:120°, Bottom:31.8°, Right:120.5°, Top:32°).

  3. After setting coverage range, click Next to configure:

    • Chart Number: Key component of group name (5 ASCII characters). Set as X0000.
    • Version Number: Initial version is 1. Increment with updates.
    • Producing Agency: Organization producing chart data (e.g., CN for China Maritime Safety Administration).
    • Navigational Purpose: Determine chart classification and scale ranges per S-57/CJ-57 standards:
      • S-57 standard includes 6 navigational purposes:
        ID Purpose Scale Range Editable Scales (1:)
        1 Overview ≤1:1.5M >3M, 1.5M
        2 General 1:350k~1:1.49M 700k, 350k
        3 Coastal 1:90k~1:349k 180k, 90k
        4 Approach 1:22k~1:89k 45k, 22k
        5 Harbour 1:4k~1:21,999 12k, 8k, 4k
        6 Berthing >1:4k <3,999

      • CJ-57 standard includes 10 inland waterway purposes:

        ID Purpose Scale Range Editable Scales (1:)
        1 Water Area Overview 1:200k >3M, 1.5M
        2 Fairway Overview 1:50k~1:200k 700k, 350k
        7 Inland Fairway 1:2k~1:50k  
        8 Inland Harbor 1:2k~1:10k  
        9 Inland Berthing 1:1k~1:5k  
        A Overlay Match base chart  
    • Group Name: S-57 filename format: "AgencyCode+Purpose+ChartNumber" (e.g., CN5X0000).
    • Update Number: Initial value 1, increments with updates.
    • Update Date: Select deadline date from calendar.
    • Publication Date: Select data availability date from calendar.
    • Dataset Identifier Note: Input ASCII comments (e.g., "20240131").
  4. After parameters setup, click Next for advanced settings:
    Create Editable Chart Group: Step 4
    • Edit Scale: Denominator value (e.g., 12000 for Harbour purpose).
    • Coordinate Multiplier: Keep default.
    • Vertical Datum: Select from 31 options (e.g., 3-Mean Sea Level).
    • Depth Datum: Select from 31 options (e.g., 23-Lowest Astronomical Tide).
    • ATTF Lexical Level: Choose Level1 (ISO 8859-1).
    • NATF Lexical Level: Choose Level2 (Unicode).
    • Dataset Parameter Note: Input ASCII comments (e.g., "huangpujiang").
  5. After verification, click Next to review all parameters.
  6. Click Done to create CN5X0000 group. Three default meta-object datasets (M_COVR, M_NSYS, M_QUAL) will be generated.
