comment R raster Package Moran's I interpretation
Your comment about "most of the literature" may be confusing the global Moran's I (which typically will lie between -1 and 1) and the local values, which can have an arbitrarily wide range (depending on how many raster cells there are).

comment How do you memorize the meaning of longitude and latitude?
A big problem with many of the answers so far is that they do not distinguish between the directions in which the coordinates change and the directions in which their isolines are oriented (which are the orthogonal directions), making them utterly useless (or worse, misleading). As with many technical terms, actually understanding them is far better than trying to memorize some bit of doggerel.

The etymology is explained at gis.stackexchange.com/questions/60796/…. Understanding this can also help you remember which is which reliably.
