Trends and Perspectives of Automated GIS Data Collection

In this paper we discuss trends and perspectives of automated data collection for Geographic Information Systems (GIS). We focus on aerial imagery and employ road extraction for the examples. The paper is split into three parts: In the first we present major findings for the (fully) automatic extraction of buildings, roads, and other topographic objects in the form of a model and a strategy. In the second part, we give an impression of the strengths but also of the problems by presenting results of the evaluation of the automated extraction of roads from aerial imagery. This leads to the third and main part of the paper where we highlight trends for automatic data collection and set them into relation to different ways to integrate human interaction in the process. Finally, we derive perspectives for automated GIS data collection.
