Detailed Description

Represents a single CM93 chart at a specific scale.

CM93 charts are a proprietary vector chart format developed by C-Map. Unlike S57 charts, CM93 charts use a different data structure and cover the entire world in a seamless database. Key differences from S57 include:

Multi-scale coverage: CM93 data is organized into several discrete zoom levels.
Proprietary encoding: CM93 uses its own object and attribute encoding, requiring translation to S57 objects.
Global coverage: A single CM93 database covers the entire world, eliminating chart boundaries.
Efficient storage: Data is highly compressed and organized in a cell-based structure.
