noun
Refers to the detailed mapping or description of the physical features of an area, or the features themselves. Used in geography, cartography, and related technical contexts.
この地域のトポグラフィーは非常に複雑だ。
The topography of this region is very complex.
地形 is the common Japanese word for 'terrain' or 'landform', used in everyday and technical contexts. トポグラフィー is a more specialized loanword often used in academic or professional settings such as geography and cartography.
Borrowed from English 'topography', ultimately from Greek 'topographia' (description of a place).
