shown in 3D view

simplify the handling

3rd coordinate dialog

available

Basic Functions

Project Settings

Several settings to configure

• Acceleration of display

• Behavior od display

• General behavior

Settings are saved with the

current vector database


Import of Data

Urban Building Databases: Vector Import

Import of urban vector building databases possible

Support of several file formats

• Arcview Shapefile

• MapInfo

• Open ASCII format

• Aircom Enterprise

• Nokia NetAct

• Siemens TornadoN

• MSI Planet

• Vodafone D2 FUN


Import of Data

Urban Building Databases: Pixel Import

Conversion of pixel files (bitmaps) to vector building databases

Support of common bitmap formats

Several parameters


Import of Data

Urban Building Databases: Simplification

Simplification of urban vector building database to accelerate prediction and

save memory

Several parameters available: Simplification of shape, combination of

adjacent buildings


Import of Data

Indoor Buildings: Vector Import

Import of indoor vector buildings possible

Support of several file formats

• Open ASCII format

• AutoCAD format

• DXF file format

• Facet file format

• MCS format

• Stereolithography format

• Nastran file format


Import of Data

Indoor Buildings: Pixel Import

Conversion of pixel files (bitmaps) to vector buildings

Support of common bitmap formats

Several parameters


Import of Data

Indoor Buildings: Simplification

Simplification of indoor vector buildings to accelerate prediction and save

memory

Several parameters available: Tolerance, conditions for combination



Loading Bitmaps

Bitmaps can be imported and put behind the scene

Bitmaps can be moved, adjusted and scaled

Easy generation of indoor and urban databases based on bitmaps

Easy dimensioning and localization based on geo referenced information



Drawing on Bitmaps

Draw perpendicular walls on the bitmap

Bitmap can be removed afterwards

Draw vertical walls Vertical walls


Generating Pixel Maps

Concept of Pixel Maps

Floor plans (*.jpg, *.bmp) can be used directly as a basis for wave

propagation predictions

No conversion of data from raster data to vector data required

Consideration of different floor plans for each floor of multi story buildings

Support of all empirical wave propagation models and Dominant Path Model



Import of Floor Bitmaps

Import of floor plans from bitmap files into WallMan

Correction of orientation and location of bitmaps for different floors by using

markers



Import of Pixel Data

Floor plans are displayed in WallMan

Here: Two floors are shown



Definition of Materials

Materials are automatically generated based on available colours

User can select which colours should be ignored (e.g. texts, lines,..)



Definition of Materials

Display of database after definition of materials

Here: All colours are neglected except ‘black’ => Easy way to remove texts

and other things with different colours from the bitmap



Ready for Usage in ProMan

After saving the database it can be used in ProMan as a basis for wave

propagation and network projects


Time Variance

Concept of Time Variance

Walls/polygons can be combined to groups

Individual time variant properties can be assigned to each group

Translation Rotation

Vector for direction

Scalar value for velocity

Center of rotation

Velocity of rotation for each axis


Time Variance

Time Variant Mode

Definition of time variant properties

Observation of time variance step-by-step Time control

Time variant properties for selected group


Time Variance

Definition of Time Variant Properties

Launch ‘time variant mode’ in WallMan

Select a group to which time variance should be assigned

Define properties for each group (by values or by using a trajectory)


Time Variance

Example

Time variant ‘Car-2-Car’ sample with propagation paths

Preprocessing

Concept of Preprocessing

Preprocessing has to be done only once before the prediction

Material properties can be changed afterwards

Preprocessing guarantees short prediction times
