Geo_reference Attributes

zone The UTM zone the Geo_reference is based in.
false_easting ??
false_northing ??
datum The datum used (default is 'wsg84').
projection The projection used (default is 'UTM').
units The units of measure used (default is metres, 'm').
xllcorner The X coordinate of origin (default is 0.0 with respect to the UTM grid origin).
yllcorner The Y coordinate of origin (default is 0.0 with respect to the UTM grid origin).

Geo_reference Methods

get_xllcorner(self) Returns the .xllcorner attribute.
get_yllcorner(self) Returns the .yllcorner attribute.
get_zone(self) Returns the .zone attribute.
write_NetCDF(self, outfile) Write Geo_reference attributes to an open NetCDF file at outfile. The attributes written are .xllcorner, .yllcorner, .zone, .false_easting, false_northing, .datum, .projection and .units.
read_NetCDF(self, infile) Read Geo_reference attributes from an open NetCDF file at infile. The attributes read are .xllcorner, .yllcorner, .zone, .false_easting, false_northing, .datum, .projection and .units.
write_ASCII(self, fd) Write Geo_reference attributes to an open ASCII file at fd. The attributes written are .zone, .xllcorner and .yllcorner.
read_ASCII(self, fd, read_title=None) Read Geo_reference attributes from an open ASCII file at fd. The attributes read are .zone, .xllcorner and .yllcorner. If read_title is None then we expect the title line in the data file to match the standard title in the first two characters. Otherwise read_title is the assumed title in the file which must match the standard title in the first two characters, and the title line is not read from the file.
