“三北”防护林遥感专题系列制图研究

Study on Thematic Series Mapping of Remote Sensing in the "Three—North Protective Forest" Regions

遥感系列制图技术是现代遥感飞速发展的前提下与地理制图学相结合的产物,具有信息源丰富、地理景观真实、内容能定性定量和快速成图等特点。遥感技术的迅速发展,将人们的视野从低空引向高空,从局部引向全球,把普通黑白和彩色象片改进为多光谱扫描图像、红外图像、合成孔径侧视雷达图像等。丰富了制图信息,为资源考察和专题研究提供了现势资料。“三北”防护林遥感系列制图是一项大面积、多图种,向着系列化、标准化、规范化方向探索的制图研究工作。

The remote sensing mapping technique is an integrated outcome of the ramote sensing development and the geographical catography. It is charcaterized by rich information source, truegeographical landscape, qualitative, or quantitative contents and quick mapping ability. The raoid development of remote sensing techniques extends man s sight from low altitude to high altitude, from local places to the globe,and changes the black - and white or color photograph into multi - spectral scanning image or infrared photograph or full aperture side - looking rader image, thus enriched mappimg imforma-tion. The remote sensing series mappimg of the 'Three-North Protective Forest' regions contains large area and many sorts of maps,being an attempt towards the mappimg standardization.
