Hi,
I am currently developing scripts to process the 2D SHP files of the extended
and projected cave profiles, and I would like to better understand how the
coordinate systems are defined.
>From my observations:
* Extended profile:
*
The X coordinate seems to start close to 0, but I cannot determine the actual
origin point. There is positive and negative coordinates.
*
The Y coordinate appears to correspond to a plan-view Y coordinate — possibly
the reference point for X — with subsequent values representing cumulative
altitude differences relative to this reference.
* Projected profile:
* The meaning of the X coordinate is still unclear to me.
* The Y coordinate appears to represent the altitude of the points.
My objective is to determine how to correctly reproject a DEM/MNT profile onto
both types of cave profiles.
Is there anyone who can help me?
Thanks
Benoit Urruty
