Why have we eXcluded Land (XL)?

Land mapping datasets tend to fill bodies of water with a shade of blue, because maritime information isn’t useful for the majority of their users. In the same vein, Nautical Charts fill land with a mustard shade. These datasets are suitable for someone navigating a car, or a ship, but what happens when your use case requires harmonised land and maritime information? RCXL is developed to solve this exact issue.

By removing the land from Nautical Charts, users are now able to combine the useful aspects of both datasets for a harmonious mapping experience across land and sea. Finally, as Nautical Charts are designed without any context of the surrounding charts, land from one chart will often overlap valid maritime data from another – a by-product of removing the land is that issue is also resolved in RCXL.
