Hi
Having edited airports there are a few things that tools like TaxiDraw provide that are invaluable;

1) super-imposing the airport layout on top of a scaled background image to allow placement of taxiways etc in proportion to the RL layout.
2) providing lat/long readout for any point on the layout.
3) showing centre lines for runways/taxiways.
4) catering for such things as edge lighting and centre line lighting etc.
5) exporting the beacon information to stg files

not to mention; layering info, (even biezer curves will need layering at the interfaces), surface types etc.

If a program like Inkscape can duplicate this and is multiplatform then by all means.....

As you might have gathered, I have no experience with Inkscape and am looking for comments and affirmations rather than flame-wars...

I believe a more generic and structured approach to the apt format is desirable as long as there isn't a re-adjustment period that means we are left devoid of current capabilities.

I also see merit in maintaining a commonality between x-plane ad fgfs as it increases the resources available for further development albeit on a cooperative basis.

We also need to keep in mind that a number of people have devoted a large amount of time and effort to interfacing with the apt.dat format, I feel their voices should be most prominent when any change like this is considered.

Which brings me to an idea. What if the airport format is enriched svg. That way the physical airport layout is in svg and might be viewed with a standard svg viever/editor. Converting electronic airport charts to svg works already. The logical layout (taxiway names, aprons, tower locations etc.) is then put
on top of that (i.e. extra tags and attributes).

Don't know wether svg editors will preserve unknown tags and attributes. If
they do, the physical airport layout can then be changed with a standard svg
drawing program (e.g. inkscape).
