This dataset consists of a file geodatabase (output.gdb) derived from the Sabah Structural Plan 2033 as described in the Section 2.1.2 (Planned road infrastructure development) of the Related Publication:
Materials and Methods [Extract]: We digitized 1295 km and 1337 km of planned new roads and planned road upgrades respectively (Fig 1) from the Sabah Structural Plan 2033 . A 1:500,000 map of planned roadways  was digitized and georeferenced to Sabahan administrative boundaries according to GADM v2.1 spatial data . Planned roadways were then manually digitized on-screen in ArcGIS at viewing scales of 1:5000 to 1:10,000. The digitized routes for planned upgrade roadways were subsequently overlaid on high-resolution imagery in Google Earth, in which the routes of existing roadways nominated for upgrade were visible.
