| Abstract: | The paper introduced the open source Library of GDAL, and used it to program to achieve the reading of Band color data directly from big Remote sensing image on PDA device. With the technology of Off-Screen Bitmap, speeding up the display of image on the device＇s screen, further more, this paper realize the operations of browsing, pan and zoom with the image in the Device, and accomplish the overlay of vector map with the raster image. |
