About Lake Toba, Sumatra
Lake Toba (Indonesian: Danau Toba, Toba Batak: ᯖᯀᯬ ᯖᯬᯅ; romanized: Tao Toba) is a large natural lake in North Sumatra and Indonesia. The lake is the massive caldera of the Toba supervolcano. The lake is located in the middle of the northern part of the island of Sumatra, with a surface elevation of about 900 metres (2,953 ft), and stretches from 2.88°N 98.52°E / 2.88; 98.52 to 2.35°N 99.1°E / 2.35; 99.1. The lake is about 100 kilometres (62 miles) long, 30 kilometres (19 mi) wide, and up to 505 metres (1,657 ft) deep. It is the largest lake in Indonesia and the largest volcanic lake in the world. Toba Caldera is one of twenty geoparks in Indonesia, and was recognised in July 2020 as one of the UNESCO Global Geoparks.

Questions about Lake Toba, Sumatra
Where is Lake Toba?
Lake Toba is in Sumatra at 2.6850, 98.8750. The model covers a 50 by 50 kilometer square around that point.
How high is the terrain in the Lake Toba model?
The land in this model runs from 0 to 2,190 m (2,190 m of relief). These are the measured heights, printed 2 times taller so the shape is easy to see.
Can I 3D print Lake Toba?
Yes. Download the free Standard resolution STL and print it on any FDM or resin printer. It is 150 mm wide and about 18.1 mm tall, on a solid 5 mm base, at a scale of about 1:333,300. It also works for CNC carving. Use Customize to change the width, base thickness or height exaggeration, make it round or add a name plate.
How accurate is the Lake Toba model?
It is built from real elevation measurements, not an artist's guess: open satellite and survey data (NASA SRTM, Copernicus and national surveys), about 30 meters per point. The shaded picture on this page is made from the same data.
Is the Lake Toba model free?
The Standard resolution model is free as STL, 3MF, Colored 3MF, OBJ and a 16-bit heightmap. High resolution samples the place about ten times more finely and is a paid upgrade.
What is a Lake Toba terrain model good for?
People use it as a geology lesson you can hold, a classroom model or a desk piece.
About this terrain model
Embossify Terra builds Lake Toba, Sumatra from real measured elevation, not an artist's guess. Outside the United States the heights come from open satellite and survey data (NASA SRTM, Copernicus and national surveys), about 30 meters per point.
The model covers a 50 by 50 kilometer square centered on 2.6850, 98.8750. It prints 150 mm (5.9 in) wide on a solid base, a scale of about 1:333,300. The heights are exaggerated 2× so the shape is easy to see and feel; you can change that when you customize the model. The sea is flattened to zero, so land stands on a clean base.
