Abstract

Analytical elevation models use functional dependences to describe heights on the Earth’s surface. This type of relief models can be used in various fields, e.g., geomorphology, gravimetry, and cartography. The main aim of this article is to assess the possibility of using analytical models to describe relief forms of varying complexity: mountains, hills, and plains. For three regions of Spain, we have constructed modified S-approximations of the function describing the relief of the Earth’s surface and analyzed the dependence of the model parameters on the degree of dissection of the relief.

构建数字浮雕模型和地球势场解析近似的有效技术

摘要

解析高程模型使用函数依赖性来描述地球表面的高度。这种类型的浮雕模型可以用于各种领域,例如地貌,重力法和制图。本文的主要目的是评估使用分析模型来描述各种复杂程度的救济形式的可能性:山脉,丘陵和平原。对于西班牙的三个地区,我们构造了描述地球表面起伏函数的修正S近似,并分析了模型参数对起伏剥离程度的依赖性。
