I need extract metadata from file .tiff but specifically I need get corner coordinates, and after convert this to lat-long.


One way to do this is to use the osgeo module, specifically gdal. Below is a sample:

from osgeo import gdal

ds = gdal.Open("my_tiff.tif")
x = ds.GetGeoTransform()[0]
y = ds.GetGeoTransform()[3]

This returns the coordinate of the top left corner of the top left pixel.

It would depend on what georeferencing is used in your tiff file to convert to Lat/Lon. If it is in utm, for example, you could use the utm module's utm.from_latlon(lat, lon). To convert the coordinates.

Other way is using rasterio module for getting coordinates, and pyproj module for converting them. Example:

import rasterio
import pyproj

my_file = rasterio.open('file.tif')
bounbox = my_file.bounds
my_proj = pyproj.Proj("+init=epsg:5514")#your data crs

left_bottom = my_proj(bounbox[0],bounbox[1], inverse=True)
right_top = my_proj(bounbox[2],bounbox[3], inverse=True)

    In my answer is example. I have data ('file.tif') in EPSG:5514 CRS, after runnig this code I get the corner coordinates (lat-long) in WGS – Oto Kaláb Dec 15 '16 at 19:45
