Support TIF/GeoTIF in TUFLOW #5

Closed saberraz closed 9 years ago

saberraz commented 9 years ago

It is not the right place to raise this, but is it possible to add support for TIF file in TGC. Working with ASCII grids are very slow in QGIS.

TUFLOW-Support commented 9 years ago

We have added in support for input and output in the binary grids in the .flt format. These can be directly read into QGIS and will be much much faster than the .asc grids. For more info see point 58 ofthe 2013-12 release notes here: http://www.tuflow.com/Download/TUFLOW/Releases/2013-12/Doc/TUFLOW%20Release%20Notes.2013-12.pdf

The asc_to_asc format has also been updated to allow conversion between the .asc anf .flt grids (and vice versa). See here for more information: http://wiki.tuflow.com/index.php?title=ASC_to_ASC#Convert

We would like to get TIF files into TUFLOW as well, however, in the intermin .flt grids should make things much faster.

Cheers Phil

Hi, it has been over 5 years since this was posted. Is there any update to ease the integration of TIFs into TUFLOW. Perhaps as a downloadable add on if you do not wish to increase the size of the TUFLOW executable? @saberraz do you have any thoughts?

The TIF format is only 1 file which includes the projection as opposed to the .flt file which has a .hdr and .prj file too. If compression is supported, this will massively reduce the size of TUFLOW models. The current solution of converting a grid from TIF (Generated in QGIS) -> ASC (Convert / translate using GDAL) -> FLT (Convert using ASC to ASC) is impractical and unnecessary in this day and age.

I dont think TUFLOW necessarily needs to output as TIF, just accepting it as an input format is sufficient. The adoption of FLT is basically nonexistent.

Hi, we are hoping to add additional vector and raster format support into the next major release of TUFLOW.
