TopOSM [Pretty Open Street Map]

TopOSM [Pretty Open Street Map]

Well done Lars Ahlzen for creating one of the best Open Street Map raster/rendering layers, highly detailed at lower zoom levels and with the mixing of terrain and contours data layers you can clearly surrounding area in 2.5D perspective.
eye in on the details, individual buildings, walking routes visible and good cartographic symbology and text placement.


Clear, defined cartographic rendering is TopOSM.
Hopefully the OpenStreetMap see's this and acknowledges your efforts.

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 was used to create the shaded relief colours.

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)
