Models for positional accuracy assessment of linear features: 2D and 3D cases

摘要

Traditionally, the uncertainty models for segments and lines and positional accuracy assessment methods based on lines have worked with 2D elements. But the increasing availability of 3D data leads us to conjecture the need to adapt existing models and methods for this type of data. This paper gathers for the first time in a single paper the uncertainty models for segments and lines and positional accuracy assessment methods based on lines, incorporating the 3D case. Thus, this paper is intended as a reference document for those readers who are interested in this field.
