Discussion
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.
|
| change_points_geo_ref(self, points, points_geo_ref=None) | Change the coordinates of a list or array of Points to be relative to a new Geo_reference. The new Point data is returned. Note that the input Point is also changed. If points_geo_ref is None then the coordinates are changed to be absolute with respect to the current Geo_reference.
|
| is_absolute(self) | Returns True if the Geo_reference origin is close to the UTM origin.
