Why does Python only read the no data value from GeoTIFF?

How to remove no data value in GDAL?

The current recommended practice for removing a nodata value is to copy the GeoTIFF using gdal_translate, specifying that the nodata tag not be copied over along with the data. By making the nodata value fully editable and removable we could avoid copying unnecessarily.

What does Rasterio open return?

Rasterio’s open() function takes a path string or path-like object and returns an opened dataset object. The path may point to a file of any supported raster format. Rasterio will open it using the proper GDAL format driver. Dataset objects have some of the same attributes as Python file objects.

What is Rasterio in Python?

Rasterio is a highly useful module for raster processing which you can use for reading and writing several different raster formats in Python. Rasterio is based on GDAL and Python automatically registers all known GDAL drivers for reading supported formats when importing the module.

Rasterio supports three primary methods for transforming of coordinates from image pixel (row, col) to and from geographic/projected (x, y) coordinates. The interface for performing these coordinate transformations is available in rasterio.

What is rasterio CRS?

A coordinate reference system (CRS) defines how a dataset’s pixels map to locations on, for example, a globe or the Earth. A CRS may be local or global. The GIS field shares a number of authority files that define CRS.
