I've been hiking in the mountains around the Taipei/Keelung area for years and have lots of photos of distant peaks from other peaks. I'd like to build a 3D surface mesh of the topography so I can play with it in Python and maybe Blender to make sense of it (personal use).
Are there publicly available topographical data for northern Taiwan that I could use to do this?
Ideally in some tabular format so that I wouldn't have to install stand-alone software in order to use. A python package is no problem. I don't mind massaging or interpolating from one coordinate system to another myself, as long as it's not too complicated.
I'm looking for resolution of something of the order of 5 meters vertically an 10 horizontally, but there's no specific hard requirement.
