I am trying to use the raster calculator in QGIS to filter out depths lower than 0.01cm (in geotif which represent a flood map, respectively the depths), while keeping the original values of the raster. When I use the syntax I always get output with 0s and 1s, or I get the raster ranging from 0 up to max, where 0s represents the values below 0.01,and I am trying to avoid that. I am trying to get raster with values ranging from 0.01 up to max.
("HQ100_2D_PD@1" >= 0.01) * "HQ100_2D_PD@1"
I know that vectorizing the raster to points, then filtering out the values in attribute table will definitely work but I am looking for more elegant and faster approach using Raster Calculator.
