Hi everyone, I have a short program the writes the output data to an acsii file:
import sys import os import string import gisdata from Numeric import * def latlon(area_id, i, j): lon_file = "lon_%s.dat" % area_id flon = open(lon_file, 'wa') lat_file = "lat_%s.dat" % area_id flat = open(lat_file, 'wa') for x in range(i): for y in range(j): flat.write("%f\n" % gisdata.xy2lonlat(area_id,x,y)[1]) flon.write("%f\n" % gisdata.xy2lonlat(area_id,x,y)[0]) flat.close() flon.close() #------------------------------------------------------------ if __name__ == '__main__': tile_info ={"ibla_35n13e":[1215,1215], "ibla_46n16e":[1215,1215], "ibla_57n40w":[1215,1215], } for t in tile_info.keys(): xsize = tile_info[t][0] ysize = tile_info[t][1] result = latlon_(t, xsize, ysize) Now this works but the output is in ascii form. Whenever I try to write it binary form by creating the 2D array and then opening the file with open("filename", 'wb'), I lose the decimals that are vital. The input data is float with about 4 decimal places. Does anyone have any ideas of how to improve this by writing the 2D array in binary form?
