From: High-risk infrastructure projects pose imminent threats to forests in Indonesian Borneo
Major planned and ongoing infrastructure-expansion networks in Indonesian Borneo examined in the current study. Parallel border roads were extracted from Indonesian Government Infrastructure Information maps for each five provinces of Kalimantan31,32,33,34,35. Trans-Kalimantan Highway data were digitized from Potter38 and the Indonesian Master Plan26. Additional roads in North and West Kalimantan were digitized from ADB71. Spatial data on planned freeway, new roads, rail lines, and rail stations in East and North Kalimantan were obtained from the Department of Forestry, Mulawarman University, East Kalimantan. The maps were created using Esri ArcMap 10.4.1 (https://www.arcgis.com).
