Island of Borneo, Indonesia Malaysia Brunei

Borneo as it was in 1930: a rainforest island where the rivers are the roads.

TERRAIN - Built from NASADEM elevation data, reprojected and scaled to Gigantomaniac 1:1 (~1:47 horizontal) - Covers the whole island: Kalimantan (Indonesia), Sarawak & Sabah (Malaysia) and Brunei - Mount Kinabalu, the Crocker, Iran, Müller, Schwaner and Meratus ranges

RIVERS & LAKES - Navigable river network carved into the terrain, following the real courses - Main rivers: Barito, Mahakam, Kapuas and Rajang, navigable deep inland (Puruk Cahu, Long Bagun, Putussibau, Kapit) - Plus Kahayan, Katingan, Mentaya, Kinabatangan, Baram and many more - Mahakam lakes (Jempang, Semayang, Melintang), Danau Sentarum and Danau Sembuluh

BIOMES - Dense rainforest across most of the island - Peat swamp and grassland in Central and South Kalimantan - Cultivated land around the 1930 towns and lower river valleys

TOWNS (51) - Starting sizes based on 1930 populations; modern names - Banjarmasin, Pontianak, Kuching, Balikpapan, Samarinda, Tarakan, Sandakan and more

INDUSTRIES (107) - Placed at historical or real-world locations: coal in South, Central, East and North Kalimantan; oil at Balikpapan, Sanga-Sanga, Tarakan, Miri and Seria; timber in Central Kalimantan; iron ore, rubber, fishing and more - Mines and logging camps sit near rivers, so barge transport works as it did historically
