Cartographic Production Method

Vector Map Production Process

1. Source Data Acquisition
   Open geographic datasets are collected and validated.

2. Topology Cleaning
   Broken geometries, overlaps, and gaps are corrected.

3. Layer Classification
   Roads, hydrography, boundaries, landmasses are separated into structured layers.

4. Projection Handling
   Data is prepared in geographic coordinates suitable for design software.

5. Cartographic Generalization
   Excess detail is reduced to improve readability at print scale.

6. Manual Editing in Illustrator
   Final map is optimized for graphic design workflows.
