I'm tasked with performing a number of corrections on several maps. I did not make the original maps.

One of these maps, featuring a fairly large city, has a total of 96 numbered locations on it. Public buildings, landmarks etc. Now, the corrections I have received call for removal of 2 of these locations... #87 and... #3

So... what do you all think... renumber or not? (they're grouped by type, so I can't simply take #96 and call it #3)

If there is an index that goes along with it (which I assume there is - how else would you know what's what) than I would renumber them. Go thing its only 96 and not 200 or 400.

Yes, there is an index, which would make it more obvious if one of the numbers is missing...

Okay, I just figured out that if I turn it into a Mapublisher layer, I can actually use the expression builder to change the text value, so that would take care of the renumbering of the map... :lol:

I wish I knew about this before...

. . . . before you actually did it manually? I'm sure that's happened to all of us at sometime.

Oh, I didn't do it manually yet for this particular one, but there's been many previous occasions (though not with the need to renumber so many locations)

This would happen frequently on CSAA maps with school numbering or in our heavily numbered recreation indexes. If there were only a few changes I'd leave the numbers alone, the gaps help to absorb additions later on. In fact we often build number gaps into large numbered indexes so that every new group would start on the next multiple of 10 (if that makes any snese).

The issue here is that the numbers are not ordinal, they help to locate the feature but don't add a value or sequnce to the feature so it doesn't matter if there are gaps.
