摘      要：The virtual globe is the default visualization for Digital Earth applications,but it can only show one half of the *** article introduces user-adjustable,on-the-fly projection of georeferenced raster images for web mapping and web GIS *** technique allows users to center a map on arbitrary locations,while still seeing the entire Earth *** web mapping libraries can apply map projection transformations to vector data in the browser,but they do not currently support the projection of raster images at interactive frame *** use the cross-platform WebGL(Web Graphics Library)graphics pipeline for hardware-accelerated projection of raster data in web *** algorithmic techniques–inverse per-fragment projection,and combined forward per-triangle and inverse per-fragment projection–for georeferenced raster imagery are *** resulting raster maps combine the ease of use and flexibility of interactive virtual globes with the ability to show the entire *** adjustable projection of raster imagery allows users to observe global phenomena that are difficult to visualize on virtual globes or traditional maps with static projections.
