I've got some elevation data represented in ascii gridded xyz-files which I want to convert to a conventional raster format. What's a bit special is that the elevation values have sub-meter accuracy, as they have one decimal (for example: '101.7')
As a rule I prefer to use open source software and stick to conventional, open, widely supported formats.
So the first thing I tried was to convert the data using gdal to geotiff, but specifying the data-type as Float32/64 distorted the elevation values somewhat. When I check the pixel-value in qgis it reports it as 101.70001220703125.
Questions:
What would be suitable raster formats for sub-meter elevation data?
Is there any other software I should consider using instead of gdal?
