#4892 closed defect

gdal_convert creates incorrect negative values when converting to ARG format. — at Initial Version

Description

reproduction:

In working directory, where ever attached dem file is located

$ gdal_translate -of ARG -ot Float32 philly_30m.dem philly_30m.arg

Actual Behavior:

$ gdalinfo -stats philly_30m.dem | grep Min

Minimum=0.000, ...

$ gdalinfo -stats philly_30m.arg | grep Min

Minimum=-32767.000, ...

Expected behavior: the Minimum for the .tiff and .arg files would be the same (0.0)

This same behavior happens if you were to convert the DEM to GeoTIFF, and then convert the GeoTIFF to ARG. The DEM and GeoTIFF formats both have a Minimum of 0.0, the ARG has -32767.0.
