摘要
结合武汉市地理国情普查工作现状,分析了采用矢量和栅格叠加方式进行地表覆盖分类的问题和不足,提出针对大比例尺地形图数据进行专题要素提取和处理的技术。研究结果表明,该方法能提高地表覆盖分类处理的效率和质量,对地理国情普查工作的开展具有一定的指导意义。
In this paper, the problems and deficiencies of land cover classification based on vector and raster overlay were analyzed under the Wuhan geographic conditions census project. The thematic elements extraction and processing technology for large scale topographic map data were proposed. The results show that this method can improve the eificiency and quality of land cover classification interprets, and show certain significance for carrying out the geographic conditions census.
