监测城市增长和衡量城市无计划扩展对于改善城市规划和发展至关重要。在本文中，我们介绍了一种监督的方法，划定城市地区使用常用的地形数据和商业GIS软件。该方法使用监督参数优化方法沿着与基于缓冲区的质量测量方法。该方法的开发，测试和评价方面的可能用途在监测建成区的空间科学在一个非常细粒度的水平。结果表明，与实际使用的沉降边界相比，建成区边界的自动划定质量更高。该办法已在德国的166个定居机构中适用。研究表明，一个非常有效的方法来提取沉降边界的地形数据和地图，并有助于量化和监测城市蔓延。此外，这项研究的结果可能会指导其他国家的政策制定者和城市规划者。
Monitoring urban growth and measuring urban sprawl is essential for improving urban planning and development. In this paper, we introduce a supervised approach for the delineation of urban areas using commonly available topographic data and commercial GIS software. The method uses a supervised parameter optimization approach along with buffer-based quality measuring method. The approach was developed, tested and evaluated in terms of possible usage in monitoring built-up areas in spatial science at a very fine-grained level. Results show that built-up area boundaries can be delineated automatically with higher quality compared to the settlement boundaries actually used. The approach has been applied to 166 settlement bodies in Germany. The study shows a very efficient way of extracting settlement boundaries from topographic data and maps and contributes to the quantification and monitoring of urban sprawl. Moreover, the findings from this study can potentially guide policy makers and urban planners from other countries.
