CS syntax for stand-alone python

BobMCkay

Hi,

I'm trying to run;
ASCII3D_to_Feature_Class

The geographic coordinate system I require is 'GDA 1994 MGA Zone 55'

I've tried
CS = "Coordinate Systems/Geographic Coordinate Systems/World/GDA 1994 MGA Zone 55.prj"

But, I get the error;
>>> ERROR 000622: Failed to execute (ASCII 3D to Feature Class). Parameters are not valid.
ERROR 000628: Cannot set input into parameter input_coordinate_system.

Some help with the correct syntax would be greatly appreciated

Cheers

Hi,

I placed the appropiate prj file in the workspace. I also placed the xyz data files directly in the workspace.
It then was asked for an average_point_spacing.
I used 2.0 and it all worked.


The figures I had to set the point_spacing;

Avg. Point Density: 0.5 pts/m
Footprint Size: 0.32m

I used the first one to assume the value of 2.0m, Am I correct?

Cheers and many thanks
