Epilogue:
The unusual second (-griv) part of this word is simply a shortened form of “grid variation.”  The iso- part, on the other hand, is a very common prefix (stemming from the Greek isos, “equal”) that shows up in a lot of words, especially in many biological, cartographical, and chemical terms.  Among my favorites in this category is ISOHEL, “a line on a map or chart connecting points receiving equal sunshine.”
