Data Production
Data visualization and management
Data analysis
Source data production
Geodatabase prodution
Desktop GIS
WebGIS
a complete GIS solution for
Road Management

MLS - Mobile Laser Scanning
TLS - Terrestial Laser Scanning
Colored and CIR 10cm ground res. digital orthophoto
Reasons:
Own data property - high res. 3D colored pointcloud and
high res. orthophoto
covering the entire road network
Full coverage of 3D geodata as own data property that is
up-to date
homogeneous
accurate
serves many fields
GIS data production capacity
on-field GIS data update ability with quick response
GIS connections with workflow management systems
geographic data publication ability for in-house and for public users
data analysis ability to have accurate information about road surface and asset management
data support for other NGOs and for local municipalities

3D Geodatabased on manageable and format independent platform, serving professional users such as road designers, asset- and traffic managers, GIS analysts and stake holders
Data acquisition
One driver, one navigator
20-80 km scan path / man-shift

1.1M point/sec
0,5-1cm point density with 50km/h driving speed

6 x 5MP images on every 5m

1-3mm relative accuracy
2-50cm absolute accuracy without GCP/GCO
1-8cm absolute accuracy with RODIS solution

200-700GB raw data/one day mission
5 x 500GB SSD disc storage
Riegl VMX 450 MLS
IMU
GPS
6 5MB camera
2 VQ 450 scanner
CU
Riegl VZ 400 TLS
additional Nikon D800 32MB camera
two external battery
various tripods for different fields
Performance
One shift, appr. 6-8 hours on mission every non-rainy days

First 10 month statistics:
390 scan projects
7 000 km scan path
30 000 km drivin km
3 300 km city road covered

appr. 10 million 5MB images
140 TB measured raw data
Statistics
One-three field operators + one post-processing operator
30-80 scan positions / man-shift

Remote (WiFi) or on-board operation

300 000 point/sec
0,1 - 0,5 cm point density in 100m disance

5 x 32MP images on every scanpositions

1-3mm relative accuracy
1-3cm absolute accuracy depends on surveyed GCP/GCO

additional GPS antenna set - not used yet

15-20GB raw data/one day mission
Internal disc storage or laptop for data storage
Performance
One or two shifts scanning operation + parallel postprocesing - depends on Project urgency and size

First 10 month statistics:
appr. 15 000 scan positions
full 3D coverage of M4 metro line stations
15 udergrounds
300 reference are scan
20 TB measured raw data
Statistics
Contractor
