 ====== Area Input Files (.IN/.IN3) ======
+{{ :eddi_example3d.jpg? | 3D View of a simple 2.5 ENVI-met Area }}
+===== 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!**
