Simple Method to Compose Multi spectral Remote Sensing Data Using BMP Image File
Abstract：The paper describes a simple method to convert multi spectal remote sensing data into Bit Map Picture (BMP) image. There is a striking similarity between the recording format of multi spectral remote sensing data and that of BMP image, both them have the similar recording unit, that is pixel; the pixels in the remote sensing record the multi spectal data of ground objects while the pixels in BMP image record the brightness value of RGB components of the pixels. Converting the multi spectral remote sensing data into BMP format and writing them into the BMP file, a piece of BMP image will be obtained. This paper gives out the detailed information about the BMP image file, and relates the procedure to convert multi spectral data into BMP images with the remote sensing data acquired from the flight of Ocean Color CCD Imager. Many pieces of clear remote sensing pictures have been obtained.Keywords：BMP;remote sensing;Ocean color- 67
