This paper describes an investigation of the source geospatial error in digital surface models (DSMs) constructed from multiple satellite images. In this study uncertainty geometry is separated into two spatial components; global that affects absolute position surface, and local varies point to point. The component caused by inaccuracy imaging process, mainly due orientation (pose) during image...

The related fields of mobile robotics and ground vehicle localization lack a linearized theory of odometry error propagation. By contrast, the equivalent Schuler dynamics which apply to inertial guidance have been known and exploited for decades. In this paper, the general solution of linearized propagation dynamics of both systematic and random errors for vehicle odometry is developed and vali...

Cube propagation has been suggested as an alternative to Jacobian integration for estimating the volume change under a deformation in three dimensions [Pai et al., 2013]. Cube propagation estimates the change in volume by approximating a three dimensional volume as a mesh of tetrahedra, which covers the interior of the volume and approximates the boundary as piece-wise triangular surface patche...
