In this project wie will develop novel, geometric-topologic and statistical methods fpr an automatic quality assessment and update of existing geo-spatial data. The necessary reference information will be derived from up-to-date digital aerial images via automatic image analysis. As an example for geo-spatial data we have selected roads in sub-urban areas. In contrast to existing approaches for quality control of road data, we will - for the first time - carry out a common and consistent modelling and processing of the road data to be assessed and the road objects extracted from the images. For this task we will set up a geometric-topologic relationship model for the roads and their surroundings, the statistical procession is based on the so called Hint-Theory. As compared to other approaches the Hint-Theory has the major advantage that not only prior knowledge can be modeled, an explicit modelling of ignorance is also possible. In this manner we expect to develop efficient and reliable algorithms for our task. This project will use German ATKIS BasisDLM data as an example. The transfer of the methods to be developed to similar, foreign data sets is possible without any problems.

在这个项目中，Wie将开发新颖的几何学和统计方法FPR FPR自动质量评估和现有地理空间数据的更新。必要的参考信息将通过自动图像分析从最新的数字航空图像得出。作为地理空间数据的一个例子，我们选择了在郊区的道路。与现有的道路数据质量控制方法相反，我们将首次对要评估的道路数据以及从图像中提取的道路对象进行共同且一致的建模和处理。对于此任务，我们将为道路及其周围环境建立一个几何学关系模型，统计游行基于所谓的Hint理论。与其他方法相比，提示理论的主要优势不仅可以对先验知识进行建模，还可以明确的无知建模。通过这种方式，我们期望为我们的任务开发有效和可靠的算法。该项目将以德语ATKIS BastenDLM数据为例。要开发到类似的方法的转移，外国数据集是可能的，没有任何问题。
