本文描述了使用高分辨率 SAR 和干涉 SAR 数据进行制图的半自动程序。提取并组合各种二维特征，以实现对场景中元素的基本而有效的识别。景观的许多相关元素都会自动提取，无需与操作员进行任何深度交互。该程序基于假设形状和图案规律的几何模型，非常适合检测人造特征，例如道路网络（人类住区外部和内部）和建筑区域。然而，它可用于提取自然特征，重点关注不同的几何模型。此外，通过特征级别的数据融合，提取的场景元素可以分为更高级别的元素，例如十字路口、桥梁和立交桥，因为该过程的特点是多尺度、基于对象的方法。
This paper describes a semi-automatic procedure for cartographic mapping using high resolution SAR and interferometric SAR data. Various two-dimensional features are extracted and combined in order to achieve a basic yet effective recognition of the elements in the scene. Many relevant elements of the landscape are automatically extracted without requiring any deep interaction with the operator. Being based on geometric models assuming regularity of shapes and patterns, the procedure is well suited for detecting man-made features, such as the road network (outside and inside human settlements) and built-up areas. It can be used, however, to extract natural features, focusing on different geometric models. Moreover, extracted elements of the scene can be grouped into higher level ones, such as crossroads, bridges and overpasses, through data fusion at the feature level, because the procedure is characterized by a multi-scale, object-based approach.
