地理空间方法已广泛用于检查酒精出口密度与各种危害之间的关系；然而，文献提供的方法细节太少，无法评估这些研究中可能存在的地理编码偏差。我们使用新西兰酒类许可和犯罪数据来评估地理编码错误。在数据最好的年份，69%的犯罪行为可以被准确地绘制出来（其中91%发生在城市地区，38%发生在农村地区）。在位置数据的准确性和特异性方面存在相当大的城乡差异。如果在其他司法管辖区存在类似的错误，则先前的调查结果可能存在偏见。在地理空间研究中应更多地考虑数据质量的影响，并应明确报告地理编码方法。(C) 2008 Elsevier Ltd版权所有。
Geospatial methods have been used extensively to examine associations between alcohol outlet density and various harms; however, the literature offers too little methodological detail to assess possible geocoding biases in these studies. We used New Zealand liquor licensing and crime data to assess geocoding error. For the year with the best data, 69% of offences could be accurately mapped (91% of those in urban areas, 38% in rural areas). There was considerable urban-rural variation in the accuracy and specificity of location data. if similar error exists in other jurisdictions, previous findings may be biased. Greater consideration should be given to the effects of data quality in geospatial studies, and geocoding methods should be reported explicitly. (C) 2008 Elsevier Ltd. All rights reserved.
