Presented by Wesley Teskey and Mohamed Elhabiby of Micro Engineering Group Abstract: Mobile mapping involves driving a vehicle with cameras and/or laser scanning equipment mounted on the vehicle, in order to acquire geometric and schematic information for buildings, infrastructure and other notable features. A computer program called VISAT Station then utilizes image and/or 3D laser scanner data in order to produce GIS data outlining the positions key features (GIS data is in the form of points, lines and polygons). GIS data with accuracies of a few centimeters can be produced by using the image and/or 3D laser scanning information provided. FME is subsequently used to convert data formats for GIS data produced so that such data can be utilized by other computer programs to generate fully processed data for clients.

2. Overview
 Who are we? (METI – Micro Engineering
Tech Inc.)
 GIS data creation (points, lines and
polygons)
 GIS data export using FME
 Processing data in CAD (and other
environments)
 VISAT features and software usage
 Conclusion and Questions

3. Overview: What is VISAT?
 Digital cameras
 Global Positioning System
(GPS)
 Inertial Navigation
 Odometer
 Laser scanners

4. System Overview
 6 cameras
 2 laser scanners
 Integrated GPS,
inertial navigation
system and
odometer
 Image capture at 1 to 10m
interval
 Autonomy of 800 km/day
 High accuracy in all survey conditions

5. GIS Data Creation Using Camera Images
 Point and click
to add create
GIS data
 All data are
fully
georeferenced
automatically

6. Pan to Left Facing Camera
 Six cameras
take a frame
at each epoch
(van location)
 User can pan
between
camera
frames

7. Pan to Right Facing Camera
 User uses
different
camera, or the
same camera
from different
epochs, to
generate 3D
point, line and
polygon data

8. User Defined Layer Structure
 The layer structure within the VISAT Station
environment is fully user defined and
customizable
 The user can also add new data features (such as
“must enter” reference data for each GIS object
created)
 Example Layer Structure:

9. Mapping View
 Overhead
mapping
view is
visible for
GIS data
within VISAT
Station

10. 3D View
 VISAT Station also has a 3D View window for
visualization of GIS Data

11. FME is used to Export to CAD from
VISAT

12. 3D Terrain Surface in CAD from GIS Data
All CAD data
created from
GIS export are
fully
georeferenced
in a user
selected
coordinate
system

13. Contour Map in CAD from GIS Data

14. GIS Data Profiles in CAD

16. More VISAT Capabilities –
Construction Example

17. More VISAT Capabilities –
Using Planes

18. Other VISAT Capabilities
 Can utilize overhead (mosaic) imagery gathered
from aircraft or satellite – this can help with data
verification and accuracy
 Can utilize control points to improve data
accuracy – the use of control points is integrated
into the VISAT environment
 VISAT custom software is used for data logging
(van driver does not need any special training);
also, custom built server software is used to store
data for client computers processing the data

19. Conclusion
 VISAT is used to create GIS data (points, lines
and polygons) from mobile mapping imagery
 Laser scanning is also utilized
 Data from VISAT can be exported using FME into
CAD (and other formats)
 VISAT software is designed for high accuracy and
high speed data processing
 METI both sells VISAT technology and performs
service work using the VISAT system
