Spatial Pattern of Uncertainties: An Accuracy Assessment of the TIGER Files

  •  Byoungjae Lee    


This study discusses the ways how the positional accuracy of the TIGER files can be measured and spatially reported.
Many people and companies use the address range of the TIGER files with the geocoding package within a Geographic
Information Systems (GIS). However, the problem is that many people have little understanding of the inaccuracy of
the TIGER files. This study examines the relationships between the distribution of inaccuracy and physical factors such
as stream and urbanity. Next, the inaccuracy of the hydrography shape file of TIGER 2000 files is calculated by
comparing it with the stream points data of United States Geological Survey (USGS)’s Geographic Names Information
System. Finally, this study examines whether there are individual patterns in each spatial data by comparing the spatial
pattern of the inaccuracies of the road and hydrography shape file.
