Heat Capacity Mapping Mission Digital Source

The HCMM Digital Source dataset includes approximately 2400 scenes of recovered digital data with a resolution of 100 dpi. The original scenes are 715 km wide and vary in length from 715 to 3,000 km. The file size is 3-13 MB depending on the length of the scene and is stored in a TIFF format. The source data was transmitted to seven ground stations and stored on binary magnetic tape. The source data on tape is no longer readable and the only remaining set of HCMM data is on black and white film.

HCMM数字源数据集囊括了约2400帧复原的数字数据，分辨率为100 dpi。原始场景宽度约为715公里，长度介于715至3,000公里之间。文件大小根据场景长度不同，介于3至13 MB，并以TIFF格式存储。原始数据传输至七个地面站并存储在二进制磁带上。由于磁带上的数据已无法读取，目前仅存的HCMM数据集仅存于黑白胶片上。
