Recently, highpointer postulated the following: >What is going to happen when the numbers are used up? The waypoint of the most recent cache placed is GCE5C6. At the current rate of new cache placements (which is obviously going to increase as geocaching continues to add new adherents, and the weather gets warmer at higher latitudes and elevations), we should reach the cache with waypoint GCFFFF before the end of April. > >Then, what will Geocaching.com do to increase the number of waypoint numbers? Is it possible to add another digit, thereby making the next waypoint number GC10000? > >Ken (a.k.a. Highpointer) > to which Team Tierra Buena responded: >Not likely, as many older GPSRs can't handle waypoints more than of more >>than six characters. But here was the thinking from TPTB (The Powers >>That Be) at the end of last year. As I recollect from subsequent posts, >>they have pretty much gone forward with what's described in here.

While I like the idea of separating cache types into MC, VC, etc. (ie. Multi-Cache and Virtual-Cache) I would think conversion to a base 36 numbering system as a 'quick fix' would create more havoc than it alleviates. For example, how do you handle all of the existing waypoints that would now be 'out of order' if placed within a _new_ numbering system? And what about the exclusion of those confusing letters and digits? (1's a I's and O's and 0's) As an (ex) software engineer, this seems to me like a programmer's nightmare. I'm not saying it couldn't be done; I'm just questioning whether it is the best solution for the amount of benefit gained. If it were me (and fortunately, it's not) I would very simply drop the 'C' from the GC designation and continue with the current hex numbering system. In other words, instead of GCF123, we would use G0F123. What is so sacred about the 'GC' prefix anyway? I could just as easily recognize a waypoint like G0F123 in my GPSr as a GeoCache and not the location of the million dollars in gold boullion I have buried in the desert (which I would designate MYGOLD or some such.) The base 36 numbering system described above is purported to increase the number of available cache designations by a factor of 25. But to do that, you have to completely change the numbering system and consequently the the code that handles and sorts the caches. By simply dropping the 'C' from the prefix, using the existing hexadecimal numbering system and (I assume) very minute, if any, changes in the software that handles it, you would increase the number of cache waypoints available by a factor 15. This seems to me like the most bang for the least buck; the highest return for the least amount of effort. And if you really want to get crazy, why not drop the 'G' from the GC number while you're at it. Thus, GCF123 would become 00F123. Again, do you really need the G to remind you that the 6 character waypoint in your GPS is a Geocache? By using six digits in a hex numbering system, you've now increased the number of possible waypoints by a factor of 255! That's a total of more than 16 million possible Geocaches! Enough to keep even the most addicted busy for a few years. Of course, you know, of those 16 million, 12 million would be micros in the greater metro Phoenix area. :-) Heck, the city(s) would have to build more parks and greenbelts! -- Sprocket
