We have reached the completion of volume thirteen of JMGL and in this issue you will find an eclectic selection of articles. Please enjoy reading and using each to your benefit. Leading the way, Jeremy Brett and Sierra Laddusaw share their ongoing work that stems from a unique group of cartographic resources forming the Maps of Imaginary Places Collection at the Cushing Memorial Library at Texas A&M University. They have built, and launched in February 2017, an ultra-successful exhibit using examples of “fantasy maps” from this collection. The “Worlds Imagined” exhibit at the Cushing Memorial Library has been so well received that the authors not only extended the timeframe for the exhibit but also created a touring version of it to allow those beyond the Texas A&M campus an opportunity to see and learn from it. In this article, they provide information about the Worlds Imagined exhibit and its content, and discovered new applications for the use of this unique map genre that enhances teaching applications in classes ranging from design and digital media to sociology to the more traditional aspects of history and visualization. Touring Fantasyland is not only an amazing story but also provides key new information related to map use for different audiences and how geographic fantasies play a strong and growing role in today’s social environment. We were delighted to receive a paper from beyond our typical North American/European group of authors, it is from Dr. Mohamed M. Yagoub, a faculty member from the Department of Geography and Urban Planning at the United Arab Emirates University. He writes about assessing the quality of GIS data in an open data environment. Here is research that is bound to strengthen the practical side of assessing GIS data techniques and applications. Assessment of OpenStreetMap Data: The Case of Abu Dhabi City, UAE is important due to its scope of geographic coverage as well as comparing quality mapping outcomes based on open data and government-derived data. This paper adds to the conversations about the need for high-quality geospatial data in particular as it applies to disaster response and recovery needs. An article from author Evan Thornberry, formerly a reference and geospatial research librarian at the Boston Public Library’s Leventhal Map Center, shares his experiences with research and reference service at a major public library with a prominent historical map collection, which offers some similarities and differences to the more often discussed research and

社论

我们已经完成了JMGL的第十三卷，在本期中，您将找到一些折衷的文章。请享受阅读和使用它们的好处。杰里米·布雷特（Jeremy Brett）和塞拉拉达杜索（Sierra Laddusaw）一路领先，分享了他们正在进行的工作，这些工作源于得克萨斯A＆M大学库欣纪念图书馆的一组独特的制图资源，形成了“虚构的地方地图集”。他们使用该系列中的“幻想地图”实例建造并于2017年2月启动了超成功的展览。库欣纪念图书馆的“想象中的世界”展览广受好评，作者不仅延长了展览的时间框架，而且还创作了一个巡回展览版本，以使德克萨斯州A＆M校园以外的人们有机会参观和学习它。在这篇文章中，他们提供有关“想象中的世界”展览及其内容的信息，并发现了利用这种独特地图类型的新应用程序，从而增强了从设计和数字媒体到社会学到历史和可视化等更传统方面的教学应用。Touring Fantasyland不仅是一个了不起的故事，而且还为不同的受众群体提供了与地图使用有关的重要新信息，以及地理幻想如何在当今的社会环境中扮演着日益重要的角色。我们很高兴收到来自我们典型的北美/欧洲作者之外的论文，该论文来自阿拉伯联合酋长国大学地理与城市规划系的教授Mohamed M. Yagoub博士。他撰写了有关在开放数据环境中评估GIS数据质量的文章。这是必将加强评估GIS数据技术和应用的实践方面的研究。OpenStreetMap数据的评估：阿联酋阿布扎比市的案例非常重要，这是因为它的地理覆盖范围以及根据开放数据和政府衍生数据比较质量地图绘制结果。本文增加了有关高质量地理空间数据需求的讨论，尤其是因为它适用于灾难响应和恢复需求。作家埃文·桑伯里（Evan Thornberry）的文章曾是波士顿公共图书馆Leventhal地图中心的参考和地理空间研究馆员，他分享了他在一家主要公共图书馆的研究和参考服务方面的经验，该图书馆收藏着著名的历史地图，与讨论较多的研究和
