<div dir="ltr"><div><div><div><div><div>Hi Daniel<br><br></div>"Band-Interleaved Format" My understanding of the format is that the .bil file itself is just a "brick of floats" (or integers, bytes, etc.) that is MxNxP, where P is the number of bands that make up this image. It is organized as all of the floats (ints) of the first row for band-1, followed by the floats for first row's 2nd ban, ..., the floats of first row's Pth band, then likewise for subsequent rows, ...<br><br></div>In your example, there's only 1 band. We see that it is 621x1405, comprised of 32-bit floats. Hence the first row is 5620 bytes in length: 1405 * sizeof(float) = 1405 * 4 = 5620. This should be relatively straightforward to read:<br><br><a href="http://ncl.ucar.edu/Applications/r-binary.shtml">http://ncl.ucar.edu/Applications/r-binary.shtml</a><br><br></div>Its not clear to me from the header whether the first row is the bottom/southern-most, or the top/northern-most.<br><br></div>Does that help?<br></div>Rick<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Oct 17, 2014 at 10:37 AM, Daniel Barandiaran <span dir="ltr"><<a href="mailto:dbarandiaran@gmail.com" target="_blank">dbarandiaran@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Has anyone dealt with these files?
