A .bsq file typically represents a binary sequence, often used in remote sensing and image processing applications. It's a raw, unformatted data file that contains a sequence of binary values representing pixel data. The file itself doesn't contain any header information or metadata describing the image dimensions, data type, or color palette. This information is usually stored in a separate header file (often with a .hdr extension) or provided through external documentation. The .bsq format is a simple and efficient way to store large amounts of image data, particularly when dealing with hyperspectral or multispectral imagery. Software that reads .bsq files relies on the accompanying header file or user-provided parameters to interpret the binary data correctly and reconstruct the image. The data is typically stored in a row-major order, meaning that pixels are arranged sequentially row by row. Because of its simplicity, the .bsq format is widely supported by various remote sensing and image processing software packages.
