Georeferenced 3D models are an increasingly common choice to store and display urban data in many application areas. CityGML is an open and standardized data model, and exchange format that provides common semantics for 3D city entities and their relations and one of the most common options for this kind of information. Currently, creating and maintaining CityGML models is costly and difficult. This is in part because both the creation of the geometries and the semantic annotation can be complex processes that require at least some manual work. In fact, many publicly available CityGML models have errors. This paper proposes a method to facilitate the regular maintenance of correct city models in CityGML. This method is based on the continuous deployment strategy and tools used in software development, but adapted to the problem of creating, maintaining and deploying CityGML models, even when several people are working on them at the same time. The method requires designing and implementing CityGML deployment pipelines. These pipelines are automatic implementations of the process of building, testing and deploying CityGML models. These pipelines must be run by the maintainers of the models when they make changes that are intended to be shared with others. The pipelines execute increasingly complex automatic tests in order to detect errors as soon as possible, and can even automate the deployment step, where the CityGML models are made available to their end users. In order to demonstrate the feasibility of this method, and as an example of its application, a CityGML deployment pipeline has been developed for an example scenario where three actors maintain the same city model. This scenario is representative of the kind of problems that this method intends to solve, and it is based on real work in progress. The main benefits of this method are the automation of model testing, every change to the model is tested in a repeatable way; the automation of the model deployment, every change to the model can reach its end users as fast as possible; the systematic approach to integrating changes made by different people working together on the models, including the possibility of keeping parallel versions with a common core; an automatic record of every change made to the models (who did what and when) and the possibility of undoing some of those changes at any time. 相似文献

在1∶500 000地质图的基础上,参考了1∶2 000 000新疆维吾尔自治区地震构造图和1∶4 000 000中国活动构造图,系统收集了近10年来的活动构造、新构造、地球物理、地震活动、盆地区第四系等厚线和GPS形变观测等资料的基础上,经综合分析研究编制新版1∶1 000 000新疆地震构造图.该图共含括第四纪以来的活动断层200余条,这些构造多经过ETM等影像资料的精确校对核实,其展布和几何特征与实际情况更为吻合.该图的编制,对新疆地区的地震烈度区划、震害预测预防、城乡建设、经济规划和地震应急等具有较重要的实用参考价值. 相似文献
