The phase indeterminacy of single frequency fringe pattern and bi frequency fringe pattern in phase analysis method has been theoretically analyzed.

Analysis of positional uncertainty based on high-resolution remote sensing images;

In this paper, the positional uncertainty models of point and lineprimitives in GIS are made.

Solution of the Indefinite Intersection Based on Elimination of the Hiding Entity;

This paper addresses node position uncertainty in wireless sensor network localization by introducing the feasible geographic region,which clearly represents all feasible position scope of sensor nodes.

The visualization of positional uncertainty for random polyline based on ε_σ model in GIS

A brand-new approach to the theory research of vector GIS positional uncertainty is inaugurated, and the theory and method which can be used for reference are also provided.

This paper integrates the positional uncertainty of geometry data in GIS with the topological relationship among the different spatial objects by establishing the subject function, then elaborates the topological relationship among the point, line and polygon all of which include positional uncertainty, and finally applies the derived results to the determination of region boundaries.
