  1. Hello,

    I’m a junio hydraulic engineer working on a river project and I really need this database to compute widths so as tu deduce the discharge after. The problem is that I don’t know how tu use the files of the original 3sec data in QGIS . the databse is represented as a package includeing different files ( “flt”, “ctl”, “hdr” ? did you manage to use this data in QGIS ?
    Thank you so much

    1. If you want to use the floating point Raster “.flt” as a raster you can try to convert it to a tiff file using gdal_translate and open the tiff file in QGIS. If you want to use the flt-file for analytics you can try the GRASS-module in QGIS or process them in the GRASS software outside of QGIS. I don’t have the password to download the files, so I wasn’t able to test these suggestions.
