Displaying Method of Remote Sensing Images Based on the Domestic Independent Controllable Platform

In order to improve the level of informationization and equipment construction of the army, and build a self-controllable remote sensing image processing system, a reading and displaying method is proposed for remote sensing images based on the open source raster geodatabase geospatial data abstraction library (GDAL) and the cross-platform application framework Qt. The GDAL is employed to read and sample remote sensing images, which are then displayed and rendered by the Qt graphical view framework. The experimental results show that the proposed method can run successfully on the Windows platform and the embedded real-time Delta operating system (Delta OS) platform, free from limitation of the operating environment of commercial remote sensing software platform. The proposed method can effectively improve the displaying of large-scale remote sensing images and computer's memory efficiency, and promote the development of remote sensing image processing system under the domestic independent controllable platform.
