This research experimentally checks the consistency of these components according to national technical regulations on basic geographic information and the construction of checking rules based on GIS analysis methods to determine the relationship between geometric objects within a layer and between two different layers. In experiments using the ArcGIS software suite on some typical feature classes of the transportation group of the uncalibrated and uncorrected geographic database of the Bien Hoa town area at a scale of 1:5,000, it was shown that: the largest percentage of errors is the relationship between the traffic bridge (CauGiaoThong) layer and the road centerline (DoanTimDuongBo), 14.22%
next is the error of duplicate data of the road network node feature class (NutMangDuongBo), at 12.11%
then the relationship between the road surface and the road boundary, at 3.52
and the error of dangles of the road centerline, at 0.97%.
