Remapping has only one denotation: making a new map i.e. of some geographical area.

In English a word can develop as many connotations as society can tolerate.

Eventually the denotation can change to the most popular and more recent connotation.

I don't see how changing one F button on a DCC throttle is any sort of remap of the device because there's no map to begin with. But then an icon isn't any sort of icon but almost nobody knows the denotation any longer. And so it goes. 

Has it even crossed your mind that regarding decoders, manufacturers have, in fact, changed the denotation of map to a connotation of map?

That said, DCC users have no practical choice but to use the terms "mapping" and "remapping" in communicating with other DCC users and with maufacturers' customer service personnel. In effect, mapping and remapping are being used as transitive verbs to lay out Function keys in a new pattern, facilitated by the construction of a Function matrix.

Experienced DCC users understand this and are conversant with the use of such terms as mapping and remapping. Less experienced DCC users and some, but not all, DC users are less likely to grasp such unfamiliar terminology. And so it goes.

So, word games aside, DCC does, indeed, involve remapping should the user find it necessary or desirable.

As always, I did not take the first shovel full out of this rabbit hole nor have I dug it any deeper or started a new entrance.

I also make no argument. I merely state the facts. Others are arguing, again as always. 

You were not the first one to use the term remapping in this thread, but you were the first, and the one and only, to claim that "DCC doesn't involve any remapping". So, in fact, you did start this ridiculous argument.

Remapping implies a map which gets remapped. DCC doesn't involve any mapping. Therefore DCC doesn't involve any remapping.

Amen.

I have now mapped out a plan for my afternoon to include a nap.

A table is not a map.

Yes it is. In software development such tables were referred to as mapping, and changing those tables were referred to as remapping, long before the term "originated" with internal cumbustion egine remapping.

You may state opinion but rarely have I seen you state fact. And fact,every thread I see your name in you are arguing.

When he does state fact, it tends to be copy/paste lifted from someone elses reply.

That's incorrect. The joke goes what do you call a lawyer half buried in sand....

 

Sorry, but no, you are again incorrect.

A fueling curve for a diesel engine is just a table of numbers.

Every engineer I ever worked with used the term "fuel mapping" for adjusting these tables. When they made large changes, "remapping" was the term.

I'm confused... is a lawyer half buried in sand or 10,000 lawyers at the ocean... it doesn't seem like you know.

For not coming here to argue...

There's a crew safety aspect that may have subliminally been a factor. Certainly sitting right out front there might have been a tad intimidating at first.

Interestingly, EMD cab units were designed to fail aft of the cab to absorb some of the blow in a collision, so the cab may have been the safest place to be

If crash forces can be transferred around the cab then occupants of the cab would be somewhat protected. The danger comes from the weight (mass x deceleration) of the train behind the cab.  That kinetic energy has to go somewhere. In auto safety design force transfer structures are used for side collision protection because crush zones are not available along the sides of passenger automobiles. Front and rear protection use crumple zones between the point of impact and the passenger cabin. That isn't feasible for locomotives. Forces decelerating the train have to be transferred around the cab somehow.

I don't think safety cabs were really designed to protect the occupants from being crushed by the train behind them, but from whatever it is they are hitting.  Most train wrecks are grade crossing accidents were the train is hitting something much smaller and barely even slowing down.  In these cases the cab just has to maintain it's structural integrity as it obliterates whatever it just hit.

EMD at least made an attempt at "crumple zones" in addidtion the railroad designers attempted to provide crash posts or pillars very early on to reduce the impact of "telescope" type injuries.

I guess the real bonehead move was to start this thread. What a tangent we have been on. Maps, lawyers, and definitions aside. The locomotive is done and waiting for it's mission.

  Eleven more sound decoders and the fleet is done. The next question is. What do I do with all the mobile decoders I have been removing?

   That's it for now.

who has NOT made a bonehead move? That is how we learn?

If your decoders are all good and working-sell them. Discount deep and move them out.

Depending on the models of the decoders I may be interested. I'll send you a PM as buying is prohibited on the threads.
