在本文中，我们探讨了使用自组织地图（SOM）处理地理参考数据时的优势。标准的SOM算法，连同变异的背景下，相关的地理参考数据的分析。我们提出了一个新的SOM架构，Geo-SOM，这是专门设计来考虑空间依赖性。通过一组基于人工数据的测试，显示了所提出的不同变体的优点和缺点。这些技术的一个真实的世界的应用是通过分析地理人口数据从里斯本的大都市区。(C)2004爱思唯尔有限公司保留所有权利。
In this paper we explore the advantages of using Self-Organized Maps (SOMs) when dealing with geo-referenced data. The standard SOM algorithm is presented, together with variants which are relevant in the context of the analysis of geo-referenced data. We present a new SOM architecture, the Geo-SOM, which was especially designed to take into account spatial dependency. The strengths and weaknesses of the different variants proposed are shown through a set of tests based on artificial data. A real world application of these techniques is given through the analysis of geodemographic data from Lisbon's metropolitan area. (C) 2004 Elsevier Ltd. All rights reserved.
