Pre-generated tile pyramids are the gold standard for web mapping. Tiles are rendered once and served efficiently via CDN.
Key Features:
How XYZ Tiles Work:
The raster is pre-processed into a pyramid of tiles at different
zoom levels. Each tile is a small 256x256 image. The browser only
loads tiles visible in the current viewport, making it extremely
efficient.

Where {z} is zoom level, {x} is column,
and {y} is row.
Best for:
• Web mapping applications
• CDN delivery
• High-traffic sites
• Mobile apps
• Offline maps (with MBTiles)
These tiles were generated using gdal2tiles.py:
