提出并探讨了一种定量评价线数据集空间精度和完整性的方法。评估使用了精度更高的数据集。该方法仅利用一般可用的GIS操作。它的工作原理是在行周围建立一些增加宽度的缓冲区。对于每个宽度，地图将被覆盖，并计算统计数据。通过将结果绘制成图形，证明了该方法的有效性。该方法使用世界数字地图（DCW）进行了探索，挪威测绘当局的国家n250地图系列作为参考数据集。
A method for quantitative assessments of spatial accuracy and completeness for line data sets is suggested and explored. Data sets of higher accuracy are used for the assessments. The method utilizes only generally available GIS operations. It works by establishing a number of buffers of increasing width around the lines. For each width, the maps are overlaid, and statistics are computed. By plotting the results in graphs, the usefulness of the method is demonstrated. The method is explored using the Digital Chart of the World (DCW), with theNorwegian mapping authority'snationalN250 mapseries as referencedataset.
