Heightmap sizes to visitormap sizes?...

[BoonieRat]

Every tutorial I've seen says to make the heightmaps 256x256 pixels, why is this?. Is there a direct relation in pixel to map size? I've made a heightmap 512x512 pixels and loaded it into visitor as a 256x256 map, so why do they ALL say use 256? Are they all copied from the same source of info verbatem, or is there a special reason?...

The main reason for asking is that 256x256 is quite a small map. I want to make a 512x512square unit map, should I use a 512x512 heightmap?...

A normal 12.8 km X 12.8 km map is composed of 256 X 256 elevation points, 65,536 elevation points in total.

A 25.6 km X 25.6 km map is composed of 512 X 512 elevation points, 262,144 elevation points in total.

Most mapa are made in the standard size, for obvious reasons, hence the 256 X 256 pixel size to represent the standard map size.
