全球一致努力将植物标本室和博物馆收藏的生物多样性发生数据数字化，这些数据共同提供了过去几个世纪地球上生命的无与伦比的档案。全球生物多样性信息设施提供了获取这些数据的最大单一门户。自 2004 年以来，它提供了对生物调查和收集数据库中的样本数据的单点访问。生物学家现在可以快速获取超过 1.2 亿个观察结果，用于许多生物学分析。我们从生物学家的角度来研究数字可用数据的质量和覆盖范围，以寻求全球范围内空间分析的分布数据。我们提出了一个使用国际豆类数据库和信息服务的分布自动验证地理数据的示例，以实证测试地理覆盖范围和准确性问题。超过 20 万条记录涵盖了所有豆类物种的 31%，其中 84% 通过了地理验证。这些数据还不是所有物种或所有国家的全球生物多样性资源。用户将在这些数据中遇到许多偏差和差距，在使用或分析数据之前应该理解这些偏差和差距。世界上许多生物多样性热点地区的数据明显缺乏。数据覆盖范围的缺陷可以通过增加资源的应用来解决，以数字化和发布这些最多样化地区的数据。但在推动在线提供更多数据的过程中，我们不应忘记，如果数据要有助于捕捉地球上生命的有意义的图景，那么一致的数据质量至关重要。
There is a concerted global effort to digitize biodiversity occurrence data from herbarium and museum collections that together offer an unparalleled archive of life on Earth over the past few centuries. The Global Biodiversity Information Facility provides the largest single gateway to these data. Since 2004 it has provided a single point of access to specimen data from databases of biological surveys and collections. Biologists now have rapid access to more than 120 million observations, for use in many biological analyses. We investigate the quality and coverage of data digitally available, from the perspective of a biologist seeking distribution data for spatial analysis on a global scale. We present an example of automatic verification of geographic data using distributions from the International Legume Database and Information Service to test empirically, issues of geographic coverage and accuracy. There are over 1/2 million records covering 31% of all Legume species, and 84% of these records pass geographic validation. These data are not yet a global biodiversity resource for all species, or all countries. A user will encounter many biases and gaps in these data which should be understood before data are used or analyzed. The data are notably deficient in many of the world's biodiversity hotspots. The deficiencies in data coverage can be resolved by an increased application of resources to digitize and publish data throughout these most diverse regions. But in the push to provide ever more data online, we should not forget that consistent data quality is of paramount importance if the data are to be useful in capturing a meaningful picture of life on Earth.
