-===== Overview ===== 
-**Area Input Files** are one of the basic files when working with ENVI-met. They specify the geometry of model environment such as buildings, plants or soils in detail.\\ 
-Information stored in the Area Input files include: 
- 
-  * position and height of buildings   
-  * position of plants  
-  * distribution of surface materials and soil types  
-  * position of sources  
-  * position of receptors  
-  * database links  
-  * geographic position of the location on earth 
-  
- 
-//From Version 3.1 on, the [[number of nesting grids]], the [[soil information for the nesting grids]], the [[model rotation]] and the position on earth are now stored in the Area Input File, not in the Configuration File! 
- 
-**ENVI-met will not accept .IN files in an old format. If you want to re-use some older file, you must open it in the Editor first and save it once to convert it into the V4.0 format!**// 
- 
-The model domain is organised as a rectangular area which extends in x-, y- and z- direction.\\ 
-In area input files, you don't "see" the z-direction as you work in the horizontal view only (since Version 3.1), but it is an important part of the model.\\ 
-The following figure shows the same example shown in 3D above in the horizontal view as it appears in the ENVI-met Editor:

-The area input files are ASCII files using a matrix format with strict format rules that must be followed to decode the data correctly.  
- 
-**Normally it is not necessary for you to deal with the internal details of the file format. It is recommended that you use the ENVI-met editor to create and maintain your area input files!**
