Based on certain features of the regions (The clothes of the people, snow, deserts, etc.)
Hoenn is probably on the equator of the Pokemon world.
Sinnoh is either towards the North or South Poles.
Kanto and Johto are closer to Sinnoh.
But remember that the maps are probably not based on what direction on the Pokemon world that the regions are facing.
Sinnoh's north may actually be South on the Pokemon world.
The Sinjoh regions are most likely near the 'North' part of Sinnoh.
The Orange islands, and the ocean to the south of Kanto/Johto are probably also near the equator, as the Water is warm enough to swim in.
Hoenn may be to the east or West of Kanto/Johto, instead of south of it.
The Pokemon world is probably much larger than Earth.
Isshu is far from the other regions.
The clothes of the playable characters hints that the region is either hot, but cold enough to wear long sleeves. Or that the region has both a snow area, and an area near the equator.
