Abstract

We study semi-local patterns of the visions for contour lines of a surface when one looks at it from a distant view in any direction. The study of such a landscape (i.e. s0-called “topography”) is reduced to the study of a certain divergent diagram of smooth mappings R ← M → R2, where M is a smooth surface. We give a generic semi-local classification of such divergent diagrams.
