I would like to extract raster information (i.e. coordinate system, cell size) to excel file using python, how can I do that?


Here is one approach that uses Rasterio to extract the raster info and Pandas to write the data to a CSV file.

import rasterio
import pandas as pd

def spatial_resolution(raster):
    """extracts the XY Pixel Size"""
    t = raster.transform
    x = t[0]
    y =-t[4]
    return x, y

def get_crs(raster):
    """extracts the EPSG spatial reference"""
    return raster.crs.to_epsg()

def write_to_csv(x_res, y_res, sr, out_csv):
    """writes the data to a CSV file"""
    d = {'x_resolution':[x_res], 'y_resolution':[y_res], 'epsg':[sr]}
    df = pd.DataFrame(data = d)

if __name__ == "__main__":
    raster = rasterio.open('/path/to/your/rasterdata.tif')
    out_csv = '/path/to/your/csvfile.csv'
    x_res,y_res = spatial_resolution(raster)
    sr = get_crs(raster)
    write_to_csv(x_res,y_res, sr, out_csv)

  • What unit is the spatial resolution calculated in??? – A Merii Nov 6 at 14:29

    @Merii, the spatial resolution would be based on your input spatial reference units. – Aaron Nov 6 at 16:24
  • Sorry if my question is obvious, but is there a way to determine what my input spatial reference units are, using rasterio? – A Merii Nov 7 at 19:28

    @AMerii Please open a new question for that--I think it would be a popular question. Otherwise, you can look it up based on the epsg: epsg.io/?q=3857 – Aaron Nov 7 at 20:10
