摘要
鉴于遥感影像GeoTIFF研究过程中对地理信息的需求,提出了基于World Wind的GeoTIFF显示方案。在对World Wind分层显示进行深入研究的基础上,采用添加GeoTIFF图层的方式显示影像数据和设置影像alpha值的方式透视影像覆盖区域的地表特征。实验证明该方案能够快速地显示GeoTIFF影像,能方便地查看GeoTIFF覆盖区域的地表特征。
In view of the demand of geographic information in the study, solution for GeoTIFF display base on NASA World Wind was proposed. On the basis of detailedly studying, the World Wind＇s layers display, the perspective of the earth＇s surface have been obtained by adding GeoTIFF-layer into World Wind＇s layers and modifying the diaphaneity of GeoTIFF image with alpha value. Experimental results show that the solution can display GeoTIFF quickly and achieve the earth＇s surface conveniently.
