I have a lot of mosaic datasets:

Zone8GK100k, Zone9GK100k, ... , Zone7GK25k, ... , Zone7Gk50K, ... , Zone7GK200K.

As I know, 7GK, 8GK... are utm zone numbers.

1) What does 25K, 50k, 100k, 200k mean?

2) What is the relation between these numbers and the ArcGis scales (1:1 000, 1:10 000, 1:24 000, 1:100 000, 1:250 000 ...)?

Update:

Thanks. I have layer Zone9GK200k. So, I set: "In beyond 1:200 000". What minimum scale(out beyond) for this layer do I set?

    Looks like a custom grid naming scheme to me. UTM zone numbers (11N, 22S, etc.) don't normally look like that. Where did the data come from? Does it include metadata describing its coordinate system and naming convention?

  • Spatial reference is Pulkovo_1942... Sorry, the reference is not UTM.

100K is short for 100 thousand (kilo) and is used as shorthand for a scale of 1:100,000.

This can be extrapolated to the other examples.

For completeness 8GK appears to stand for Pulkovo 1942 / Gauss-Kruger zone 8.
