GIS支持下的海洋光学调查成果专题图编制研究

Study on Marine Optical Investigation Thematic Map Preparation Based on GIS

制作海洋光学数据专题图可以充分展示项目调查成果,为海洋研究者深入了解我国近海水体光学特性提供直观、可靠的依据,因此快速编制高质量的海洋光学专题图件具有十分重要的意义。文中分析探讨了利用GIS技术进行专题图制作的过程及关键问题,重点研究了ArcGIS地理统计分析方法及原理,并利用该方法制作了海洋光学调查区块专题图。提出了一个基于GIS的专题图制作基本模式,既提高了制图效率,又提高了现有数据利用率。

Thematic map preparation using marine optical investigation data can fully display project survey results, it also provide in- tuitive and reliable basis for marine researches who want to understand the ocean optical properties, so it is of great significance to provide high-quality ocean optical thematic map quickly. The analysis discusses about the process and key issues of thematic map preparation using GIS technology, in particular research on the method and principle. Thematic map in marine optical investigation area is also made. Finally, a GIS-based basic models in thematic map preparation is brought forward, which improves not only map- ping efficiency but also data utilization.
