4.4 Background Images
Building an accurate VISSIM model from scratch requires at least one scaled
map that shows the real network. The image file of a digitized map can be
displayed, moved and scaled in the VISSIM network window and is used to
trace the VISSIM links and connectors.
In the VISSIM 64 bit edition, the selection of background image file formats
is limited. Files with some vector formats (*.DWG, *.DXF) may not be
displayed correctly. Work-around: Convert the file to a raster graphics
format (e.g. *.BMP, *.JPG) with a graphics program.
Display option settings can be stored in the *.INI file, cf. section 4.5.
4.4.1 Supported Background Data Formats
VISSIM can display various image file formats, both bitmaps and vectors.
Among the supported formats are:
Supported bitmap formats Supported vector formats
BMP DWG 1)
JPG DXF 1)
PNG EMF
TGA WMF
TIF (uncompressed & packbits)
SID (Mr. SID)
(best resolution for display)
ECW (fixed resolution only)
SHP (shape files)
1) TM
Note: Each new version of Autodesk AutoCAD will update DWG and
DXF formats automatically. VISSIM can handle DWG versions 13 - 15 and
DXF versions 9 - 14.
*.DWG and *.DXF files may contain multiple images. Currently only the first
image of a file is shown in VISSIM.
4.4.2 Workflow: Creating a Background
The following steps explain how to convert image files to VISSIM background
maps. We recommend to start with a map which shows the entire network
area:
