The first mention of such experiments in Slovenian karst dates back to history and the beginnings of their use in the water resources management process in the first years of the 20th century. From that point on, more than two hundred tracer tests were carried out in Slovenian karst. Unfortunately, their results often remain hidden in internal reports in the archives of implementing organisations and are very difficult to access. The search for published results is also a time-consuming process, despite the possibilities of the use of search engines and key words. Due to the need for a systematic and rapidly accessible digital inventory of the tracer tests results, such inventory was designed and is now freely accessible in the Environmental Atlas (Atlas okolja), the spatial information system of Slovenian Environment Agency. In the database the results of 231 available tracer tests have been assembled, arranged and georeferenced. The article describes the data set concept, the process of collecting, verifying and evaluating data and the method of their transformation into a GIS database. Two points layers (injection site and sampling site) and one line layer (linear connection between both sites) were created. Symbology of line layer varies with different type of connection between injection and sampling site.

建立一个可自由使用的地理信息系统数据库,其中载有地下水追踪的结果及其使用的可能性
人工示踪剂示踪是研究岩溶含水层地下水流动方向和特征的一种非常好的方法。首次提到在斯洛文尼亚岩溶中进行的此类实验可以追溯到历史上,以及20世纪头几年开始在水资源管理过程中使用这些实验。从那时起,在斯洛文尼亚喀斯特地区进行了200多次示踪测试。不幸的是,它们的结果往往隐藏在执行组织档案中的内部报告中,很难获取。尽管有可能使用搜索引擎和关键词,但搜索已发布的结果也是一个耗时的过程。由于需要对示踪剂测试结果进行系统和快速访问的数字清单,设计了这样的清单,现在可以在斯洛文尼亚环境局的空间信息系统环境地图集(Atlas okolja)中免费访问。在数据库中,对231项可用示踪剂测试的结果进行了汇编、排列和地理参考。本文介绍了数据集的概念,数据的收集、验证和评估过程,以及将数据转换为GIS数据库的方法。创建了两个点层(注射部位和采样部位)和一个线层(两个部位之间的线性连接)。线层的符号随着注入和采样点之间连接类型的不同而变化。点击单个元素,示踪剂测试的选定数据为GEOLOGIJA 63/2203-220,卢布尔雅那2020https://doi.org/10.5474/geologija.2020.017©作者2020。CC Atribution 4.0许可证204 Metka PETRIČ,Nataša RAVBAR,Petra GOSTINČAR,Peta KRSNIK&Marina GACIN
