How to convert float raster to integer raster?
– Geographic Information Systems Stack Exchange Closed 4 years ago. I am using Normalize difference vegetation index (NDVI) derived from the landsat satellite band 3 and band 4 that have float values ranges from -1.0 to 1.0. I want to see the attribute table that is not possible in QGIS.

How to round pixel values of a raster in QGIS?
How can i scale see the better contrast in colour palette using qgis 2.40 I think this has been answered here How to round pixel values of a raster in QGIS? Basically, QGis Raster Calculator does not do float <-> int conversion. Use gdal_translate instead.
What kind of algorithm is used to convert raster maps?
This conversion utilizes Floyd-Steinberg dithering (error diffusion) to maximize output image visual quality. If you want to classify a raster map and want to reduce the number of classes it can be helpful to downsample your image with this algorithm before. This algorithm is derived from the GDAL rgb2pct utility.
How to convert dem to floating point raster?
I am looking to convert a .DEM exported from AutoCad to a floating point raster file type (.FLT) utilizing QGIS to implement in HEC-RAS Mapper. This is accomplished easily in Arc using the Raster>Float option. Referencing ESRI Supported Formats it does not appear the .FLT format is proprietary.
Can a raster to float format be used in arc?
This is accomplished easily in Arc using the Raster>Float option. Referencing ESRI Supported Formats it does not appear the .FLT format is proprietary. It does mention “Write—Only via Raster To Float tool, or developer code” which could suggest that it could be incorporated into QGIS.
