Description

Suggestions
ERROR 0635 - TUFLOW does not currently support TIF tile format.
The TIF format supports storing data in both a tiled and strip structure. The 2023-03-AA release only supports the strip structure as this is the most common and the default out of QGIS/GDAL.

To convert a tiled GeoTIFF to a format that TUFLOW 2023-03 can read, please use one of the steps below. Please ensure you don't select 'Cloud Optimised GeoTIFF' as an output as this format uses a tiled format.

• Open the GeoTIFF in QGIS and export it into a new GeoTIFF (QGIS by default will use a strip structure)
• Use the raster conversion tool in QGIS (via the menu "Raster >> Conversion >> Translate") - the default GeoTIFF format will be use the strip structure
• Use "raster_translate" GDAL tool either through the processing toolbox in QGIS or by following the instructions on the following wiki page to use GDAL directly:
