====== ArmA 3 Terrain Grid and Cell Sizes ======

This page is "modular" or "inheriting" so first you must read [[arma:terrain:grid_cell_size|arma terrain grid and cell sizes]] page to know the background and other sizes than listed below.

What size is your terrain? How to describe it on forums / chats? What size are official bis terrains? 

New capability in ArmA 3 is that it / terran builder now supports 8192 grid heightmaps. Note: 8192 grid heightmaps make terrain builder extremely unstable (freezes or even crashes are normal behavior), it is not recommended to be used unless you are //experienced// terrain developer.

**Do NOT use 8192 grid heightmap!**
^ Grid Size ^ Cell Size ^ Kilometer x Kilometer ^

The km x km is the standard we have used since 2001 OFP era. To explain your terrain size use "km x km" or just "km" for example "40km terrain" to keep it simple. Never use any other odd mumbo jumbo value system.

Some terms for below table:\\
**Satellite Tile** is NOT satellite "texture", it is the TILE to which satellite texture is chopped. These tiles can be found in Layers\ dir as *.paa files.\\
**Texture Layer** is internal WRP tech which is complicated to explain and basically is useless info in this pages context but we added it to be thorough.
