Indoor ASCII Database Format (IDA)

The IDA database-files (Indoor Database ASCII) are in a simple ASCII format.

An IDA file starts with the following header:

`* Indoor Database * * Last changed on: 23. 9.2009 9:41:44 *`	Arbitrary number of title or comment lines. The “*” is optional, no special comment character required.
`BEGIN_MATERIAL`	This keyword marks the beginning of the material data.
`* [MATERIAL] [ID] [GENERAL] ["Name of Material"] [Thickness (in cm)] [Filled in Display] [Color: Red] [Color: Green] [Color: Blue]`	The structure of the material properties belonging to the visualization settings.
`* [MATERIAL] [ID] [FREQUENCY] [Frequency (in MHz)] [Dielectricity (relative)] [Permeability (relative)] [Conductivity (in S/m)] [Transmission Loss Vertical (in dB)] [Transmission Loss Horizontal (in dB)] [Reflection Loss (in dB)] [Diffraction Loss incident min (in dB)] [Diffraction Loss incident max (in dB)] [Diffraction Loss diffracted (in dB)]`	The structure of the material properties belonging to the electrical settings for each defined frequency.
`MATERIAL 1 GENERAL "Material 1" 10.00000 1 0 0 0`	Sample Code.
`MATERIAL 1 FREQUENCY 2000.000 4.000000 1.000000 0.010000 10.000000 20.000000 9.000000 8.000000 15.000000 5.000000`
`END_MATERIAL`	This keyword marks the end of the material data
`BEGIN_WALLS`	This keyword marks the beginning of the building data.
`1`	Total number of walls [integer value].
`1 4 33.000, 25.500, 0.000 75.000, 25.500, 0.000 75.000, 57.500, 0.000 33.000, 57.500, 0.000 1 0`	Sample Code.
`END_WALLS`

Contrary to the urban databases, no offset can be defined.

WallMan and ProMan return an error if the number of walls is incorrect when the file is processed.

Following the header, there is one line for each wall or subdivision of the described buildings. At the beginning of the line, an optional comment may be inserted between “*” signs. Unlike in the header, now the “*” signs are compulsory.

If no subdivisions are defined for a certain wall, then the {Number of Subdivisions} parameter is set to zero. If there are subdivisions, the parameter {Number of Subdivisions} defines, how many subdivisions exist for that individual wall.

The subdivisions are then defined exactly like the walls, with only one difference: The {Number of Subdivisions} parameter is omitted (see example below).

The lines for the defined subdivisions must come directly after the corresponding wall.

Each line is structured as follows:

* comment *

{Wall Index Number [integer]}
{Number of corners [integer]}
{x-coordinate of corner # 1 [float]} ,
{y-coordinate of corner # 1 [float]} ,
{z-coordinate of corner # 1 [float]}
{x-coordinate of corner # 2 [float]} ,
{y-coordinate of corner # 2 [float]} ,
{z-coordinate of corner # 2 [float]}
              .....
{x-coordinate of corner # n [float]} ,
{y-coordinate of corner # n [float]} ,
{z-coordinate of corner # n [float]}
{Material Index Number [integer]}
{Number of Subdivisions (float)}

At the end of the wall description, the keyword

END_WALLS

marks the end of the file.

This is a sample file containing only one wall with one subdivision:
