Natural history collections are a resource for research on the taxonomy and systematics of organisms. Specimens and the associated data are now used in studies of ecology, conservation and environmental biology. Much of the museum data lacks geo-referenced collection locations, such as map coordinates or latitude and longitude. It is estimated that the number of specimens in US collections alone exceeds 750 million. Usually, the collection location is recorded as a string of text that describes the location as position along a road and/or distance from a town or other point of reference. Capture map coordinates from these text descriptions is tedious and time consuming. In this activity, a suite of software tools will be developed that will enable the biological collection community to geo-reference quickly all of the locality data associated with their collections. A prototype system, using a pattern-matching algorithm to break down the text string, has been developed. Available place names in a database are associated with latitude and longitude coordinates. When place-name data are missing, a database of other geographically-referenced information is compiled and used. The tools will also include visualization, correction and error estimation features for more precise location and updates to the database.

自然历史藏品是生物分类学和系统学研究的资源。 标本和相关数据现在用于生态学、保护和环境生物学的研究。 许多博物馆数据缺乏地理参考的收藏位置，如地图坐标或纬度和经度。 据估计，仅美国收藏的标本数量就超过7.5亿件。 通常，收集位置被记录为一串文本，其将位置描述为沿道路的位置沿着和/或距城镇或其他参考点的距离。 从这些文本描述中捕获地图坐标既繁琐又耗时。 在这项活动中，将开发一套软件工具，使生物收藏界能够迅速对与其收藏有关的所有地点数据进行地理参照。 一个原型系统，使用模式匹配算法来打破了文本串，已经开发。 数据库中的可用地名与纬度和经度坐标相关联。 如果缺少地名数据，则汇编和使用其他地理参考信息数据库。 这些工具还将包括可视化、校正和误差估计功能，以便更精确地定位和更新数据库。
