Ottoman cartographic materials are important sources of information on 19th and early 20th-century Greater Syria. However, large portions of this corpus have yet to be examined. This study explores a rare mid-19th-century Ottoman map of the Province of Saida preserved in the Ottoman Archive in Istanbul. It lists travel times between villages, towns, and administrative centers in Greater Syria under Ottoman rule, and shows the network of routes connecting these localities. Using an historical GIS approach, we evaluated the characteristics of the map and its cartographical accuracy and merits. The network of routes on the map is compared to route reconstructions based on least-cost-path principles. The discussion focuses on the historical context of the map and the ways in which it reflects the strength of Ottoman rule and familiarity with Greater Syria at the time.

使用历史地理信息系统分析奥斯曼帝国大叙利亚的路线：1849 年赛达地图

奥斯曼地图资料是有关 19 世纪和 20 世纪初大叙利亚的重要信息来源。然而，这个语料库的很大一部分还有待检查。这项研究探索了保存在伊斯坦布尔奥斯曼帝国档案馆中的 19 世纪中叶罕见的赛达省奥斯曼帝国地图。它列出了奥斯曼帝国统治下大叙利亚的村庄、城镇和行政中心之间的旅行时间，并显示了连接这些地方的路线网络。我们使用历史 GIS 方法评估了地图的特征及其制图准确性和优点。地图上的路线网络与基于最小成本路径原则的路线重建进行比较。
