tiff文件转换为PCRaster文件

QGIS解决方案

You can do that on menu “Raster” > “conversion” > “Translate”, and when setting your options you have to specify the field “Output data type”.

Ex: if your map has only integers you can set Int32, or if you have real numbers “Float32”

Then you have to change the “Converted field”, set file name and save Location, there you specify the “.MAP” file extension

4. Convert GIS formats
   4.1. Convert raster formats
   gdal_translate’s primary function is to change between image formats. The basic syntax is:

gdal_translate -of FORMAT inputFile outputFile

All supported formats can be found here.
Now we are going to convert the DEM from geoTiff to SAGA format. SAGA is a GIS which has its own -gdal-supported- binary format with the .sdat extension.
