The spatial concentration of tourists poses a challenge for many cities. Understanding the projected and perceived images of the city via social networks may help to improve management of this phenomenon. That said, social networks tend to be studied in quite a uniform way. The present study analyses the differences that could exist between 784 images posted on the Instagram network by tourist boards (projected) and 10.590 posted by visitors (perceived). The study is based on the case of Barcelona. The use of cartographic analysis tools indicates that tourist boards tend to focus on just a few specific locations. Nevertheless, user-generated images show a wider range of locations, which multiplies by seven the area where the images of the tourist board are concentrated. That said, in both cases, the images posted tend to be located in the central areas of cities. The fact that Instagram tends to reinforce the image of central spaces and that it has only a limited capacity to promote new tourist attractions outside what are already the most consolidated areas for tourism has been underlined.

游客的空间集中度对许多城市构成了挑战。通过社交网络了解城市的投影图像和感知图像可能有助于改善对此现象的管理。话虽如此，社交网络往往以相当统一的方式进行研究。本研究分析了旅游局在Instagram网络上发布的784张图像（预计）与访客在感知到的10.590张图像之间可能存在的差异。该研究基于巴塞罗那的案例。制图分析工具的使用表明，旅游局往往只专注于几个特定的​​位置。但是，用户生成的图像显示的位置范围更广，乘以旅游局图像集中区域的7倍。也就是说，在两种情况下，发布的图像往往位于城市的中心区域。有人强调，Instagram往往会增强中心空间的形象，而在已经是最巩固的旅游领域之外推广新的旅游景点的能力却很有限。
