[MetaCRS] Standard (and simple) format for conversion tests.

[Landon Blake]

I will be helping Martin Davis on some testing and improvements to
Proj4J. One of my tasks will be to test some of the improvements we are
making to the coordinate conversion calculations. I think this testing
is currently being done with Java unit tests. A while back on this list
I remember we discussed a simple format for test data that could be
provided to software tests. I think the goal would be to assemble a
standard library of test data files that could be used by different
coordinate conversion projects.

 

Is there still an interest in this?

 

I'd like to suggest the following format for a simple text file that
could store the data:

 

Document Version Number

Source Coordinate Reference System Identifier (EPSG Code for the time
being.)

Destination Coordinate Reference System Identifier (EPSG Code for the
time being.)

Source Coordinates (Space Delimited and in X Y Z Order)

Destination Coordinates (Space Delimited and in X Y Z Order)

 

This is just my idea. We could tweak the format as needed to suit the
needs of others.

 

I would be willing to maintain the library of test data files for
MetaCRS if we decide to cooperate on this issue.
