ok, so the 2 layers are not in the same projection, nor in the same datum.

You didn't mention which software does the overlay between the 2 layers, and what was the amount of shift you observed.

Software based on recent PROJ versions will typically apply HPGN grids to do NAD83 to WGS 84 coordinate transformations, when they are available, but the amount of correction due to those grids seem to be at most of 1 metre.

    Brandon,

    The output of gdalinfo on 2 misaligned rasters would be more telling.

    Hi All,

    I've been having an issue where VFR Raster Sectionals (from
    faa.gov <http://faa.gov>) and MrSid imagery are misaligned when
    compared to my other raster layers.In other software these appear
    correctly, so I figure there must be something I'm doing wrong,
    but I haven't been able to figure it out.

    Do you know what could cause this? I've attached some screenshots
    with a reference point to show the misalignment - the black and
    white satellite imagery is representative of what I see for most
    raster formats.

    Thanks in advance!
