Detailed Shaded Relief of the World

Detailed Shaded Relief of the World

Detailed Shaded Relief of the World
One of the biggest custom tiles for google maps your likely to see.

This gives high quailty coverage and is still in 'work in progress' so more to come.

"We have uploaded up to zoom level 8 completely and have the Northern hemisphere of level 9 completed - Southern Hemisphere in progress - just 60,000 tiles to go"

Well done to Jon Parker for his time and efforts on this demanding project

Global Mapper

VMAP0 vector data to include rivers and lakes and mask the coastline

Rasterised with Digital Elevation Model (DEM) to produce more detailed at larger scale (zoom in)
