Daerah Istimewa Yogyakarta — contours, 25 m (Copernicus GLO-30)

GLO-30 is a Digital SURFACE Model: heights include forest canopy and building roofs, not bare earth, so wooded and built-up cells read metres to tens of metres above the ground. Vertical datum is the EGM2008 geoid, not the WGS84 ellipsoid. Source acquisition is TanDEM-X radar, 2011-2015. Contours therefore follow the canopy and rooftops, not bare earth, and are noticeably crenellated in forest — this is the surface the DEM measured, not a drafting error. A display layer: read elevation from the hex layer, not by interpolating between these lines.

Contours traced at 25 m intervals over the same mosaicked, AOI-masked GLO-30 grid (Copernicus_DSM_COG_10_S09_00_E110_00_DEM, Copernicus_DSM_COG_10_S08_00_E110_00_DEM), clipped to the 5 ADM2 units of Daerah Istimewa Yogyakarta (COD-AB v01); each line simplified with Douglas-Peucker at 0.0002 deg (~22 m, below the 30 m source posting) and rounded to 1e-5 deg. 13566 fragment(s) left with fewer than 5 vertices were dropped.
