The article considers the problem of loss of geometrical accuracy during cartographical
generalization of digital maps, including the reasons of loss of geometrical accuracy in
general and in relation to relief layer. The results of analysis proved applicability of the
known algorithms of creating lines of identical level (horizontals, isolines, isohypses).
Recommendations on selection of a method for automatic generalization are given. A de-
scription of the method and empirical estimation of its parameters are presented.
Accord-
ing to the results of testing we offer to identify and generalized contour trend excluding
accidental
external and internal stochastic influences
on its form
.
Key words:
geographic information systems, cartographical generalization, contour of
natural object, horizontal, isohypse, geometrical accuracy, digital maps.
