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...

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...
