NEW METHODOLOGY OF REPRESENTING THE POSITIONAL ERROR OF NONPOINT FEATURES IN GIS
Positional error Non-point feature Indicators Shape similarity
2016/1/3
Traditionally, RMSE is used to represent the positional error of GIS features including point, linear and area features. Although RMSE can reflect the error of point features effectively and accuratel...

Error Propagation Overlay Analysis Vector Data GIS Sliver
2015/12/3
A spatial error may refer to the difference between a measured value and the “true” value or the estimated uncertainty with respect to a given observation or set of observations which is the error con...

2015/9/28
Spatial information Web services are beginning to be used for disseminating general purpose (mapping-grade) geographic information. They allow integrated use of geolocated data from varied sources by ...
ERROR−AWARE GIS AT WORK: REAL−WORLD APPLICATIONS OF THE DATA UNCERTAINTY ENGINE
Attribute Uncertainty Positional Uncertainty Probability Distribution Function Spatial Uncertainty Propagation Stochastic Simulation
2015/9/28
The call for the development of geographical information systems that can handle uncertain data dates back at least twenty years. Many research groups have since worked on the design of an ‘error-awar...
The Importance of Understanding Error in Lidar Digital Elevation Models
Laser Scanning Error Urban Accuracy
2015/7/9
The paper presents the results of an accuracy analysis of a number of gridded Digital Surface Models (DSMs) which have been
created from first return laser scanning (LiDAR) data. DSMs are created usi...
