The aim of this article is to provide a dedicated approach to the realisation of a CityGML model for the valorisation and the conservation of existing cultural heritage. In particular, for the ancient city of Taranto (Italy), several levels of details (LODs) have been built. CityGML models in LOD1 for the most representative periods were realised, which were characterised by urban changes from the mid-1800s until today. To achieve this aim, great importance was devoted to the process of integration of the different file formats. A geographic information system (GIS) approach has been put in place for the construction of the CityGML model in LOD1. In addition, the study also focused on the realisation of a CityGML model in LOD3 of a bridge of a particular historical and architectural interest, called “Ponte di Porta Napoli”, also situated in the city of Taranto. In the latter case, the CityGML model was realised starting from the geomatics survey. Therefore, the project structured in this way represents an important tool for the sharing of (georeferenced) territorial information. The CityGML models represent a valid support for spatial planning processes and measures for the protection, monitoring and conservation of urban elements.

遗产保护和管理的CityGML多尺度方法：以塔兰托旧城区（意大利）为例

本文的目的是为实现CityGML模型的实现和现有文化遗产的保护提供一种专用的方法。特别是对于塔兰托（意大利）古城，已建立了多个级别的细节（LOD）。实现了LOD1中最具代表性的时期的CityGML模型，其特征是从1800年代中期到今天的城市变化。为了实现该目标，非常重视不同文件格式的集成过程。地理信息系统（GIS）方法已经到位，用于在LOD1中构建CityGML模型。此外，研究还着重于在LOD3中实现具有特定历史和建筑兴趣的桥梁“ Ponte di Porta Napoli”的CityGML模型的实现，也位于塔兰托市。在后一种情况下，从地理调查开始就实现了CityGML模型。因此，以这种方式构造的项目代表了共享（地理参考）领土信息的重要工具。CityGML模型为空间规划过程和保护，监测和保护城市元素的措施提供了有效的支持。
