      Usage:
          map_pixel(xcoord, ycoord, x_cell_size, y_cell_size, xmin, ymax)
  
  
      where:
              xmin is leftmost X coordinate in system
  
              ymax is topmost Y coordinate in system
  
      Example:
              raster = HMISea.tif
  
              ndv, xsize, ysize, geot, projection, datatype = get_geo_info(raster)
  
              row, col = map_pixel(x,y,geot[1],geot[-1], geot[0],geot[3])

      col = np.asarray(col)
      row = np.asarray(row)
      point_x = xmin+col*cellx
      point_y = ymax+row*celly
      return point_x, point_y
