Webbitmap indexing, in two scientiﬁc applications: rocket simulation and vegetation pattern studies. We com-pare our empirical results with the predictions of the previous work on bitmap indexing for scientiﬁc data [12, 11, 10], which was primarily analytical in focus. In particular, we found problems with bitmap size and WebBitmap pixels are stored as bits packed in rows where the size of each row is rounded up to a multiple of 4 bytes (a 32-bit DWORD) by padding. The total amount of bytes required to store the pixels of an image can not be directly calculated by just counting the bits.
