Instructions for Use

The Standard Map Frame function adds standard map sheet frame data to maps and saves results as CAD datasets in specified datasources. This tool enables quick creation of various maps based on national basic scales to enhance cartographic professionalism. It incorporates national basic geographic data (residential areas, water systems, land use, contours, administrative divisions) sharing the same coordinate system into standard sheets, along with slope scales, adjacent charts, and drafting information, facilitating rapid production of comprehensive standard maps.

This function complies with the latest national standard "GBT 13989-2012 National Basic Scale Topographic Map Subdivision and Numbering", applicable for 1:1,000,000 to 1:500 scale topographic maps.

Fundamentals of Topographic Map Subdivision

Chinese topographic map scales include: 1:1,000,000, 1:500,000, 1:250,000, 1:100,000, 1:50,000, 1:25,000, 1:10,000, 1:5,000, 1:2,000, 1:1,000, 1:500. These scales are grouped into four categories:

• Group 1: 1:1,000,000, 1:500,000, 1:250,000
• Group 2: 1:100,000, 1:50,000, 1:25,000
• Group 3: 1:10,000, 1:5,000
• Group 4: 1:2,000, 1:1,000, 1:500

Scales 1:500, 1:1,000, and 1:2,000 are classified as large-scale, others as medium/small-scale.

1:1,000,000 maps follow international subdivision standards with 6° longitude × 4° latitude per sheet. Smaller scales (1:500,000-1:5,000) subdivide parent sheets using specified longitude/latitude differences. For example, each 1:1,000,000 sheet divides into 2×2 (4) 1:500,000 sheets with 3°×2° coverage. This hierarchical subdivision continues through all scales.

1:2,000-1:500 scales may use either geographic subdivision or rectangular tiling (50cm×50cm or 40cm×50cm). The table below shows map ranges and row/column relationships for various scales:

Step 1: Basic Parameter Settings

1. Open target map. On the Map tab's Drawing gallery, click Standard Map Frame to open the dialog:
2. The dialog lists scale-specific sheet dimensions and numbering formats, displaying longitude/latitude differences and sheet numbers for reference.
3. Map Generation Style: Two generation methods:
   • Designate Map Number: Creates frames using specified sheet numbers (new/old standards). Pre-1990 data typically uses old standards differing in frame decorations (e.g., requiring painter information).
   • Designate Scale: Generates frames by specified scale and map range. Select basic scale from dropdown.
4. Output Result: Set output dataset name and target datasource.

Step 2: Medium/Small & Large Scale Parameters

Map Range

• Start Longitude/Latitude: Required when using Designate Scale. Use combo box buttons to switch units.
• Sheet Width (Longitude Diff.): Displays fixed width based on scale.
• Sheet Height (Latitude Diff.): Displays fixed height based on scale.

Frame Drawing

• Outer Frame Line Width: Sets outer frame line width (mm). Defaults vary by scale.
• Inner-Outer Frame Spacing: Distance between frames (mm). Defaults vary by scale.

Draw Grid: Check to add graticule/kilometer grid. Kilometer grids apply to 1:5,000-1:250,000 scales. Grid spacing adjustable except 1:1M/500K.

• Grid Type: Crosshair or solid line for 1:250,000-1:5,000.
• Kilometer Grid Spacing: Default spacing varies by scale (kilometers).

Three-North Diagram: Draws magnetic declination and meridian convergence angle (1:25K/50K/100K in sheet number mode).

Three-North Directions Diagram

• Magnetic Declination: Angle between magnetic and true north.
• Meridian Convergence: Angle between grid north and true north.

Slope Scale: Adds slope scale with settable contour intervals (1:5K-1:100K).

Slope Scale Example

• Contour Interval: Defaults: 5m (1:25K), 10m (1:50K), 20m (1:100K).

1. After Step 1 setup, click Next for scale-specific parameters. Medium/small scales (1:1,000,000-1:5,000) and large scales (1:2,000-1:500) have different settings.

Notes

1. Scales below 1:2,000 require projected coordinate systems (no geographic/planar).
2. Scales ≥1:2,000 support only User Custom or National Coordinates (Xi'an 1980).
