Class Summary
This class gives an insight on how MÁV, the Hungarian State Railways has
collected 1 350 000 objects with high precision (5 cm ~ 2 inch) with limited
budget in 14 month. Data collection is key success factor of GIS projects. From 50
- 90% of resources are often used for data collection. The railway is a multi-utility
environment including civil & electrical engineering. 220 object types were
measured in one measurement process.

Challenges in May 2009





Limited budget
2011-01-02 deadline
Limited availability of updated maps
Some unsuccessful GIS initiatives
No surveying experts

Analyzed data collection alternatives:

Geodetic surveying


Raster design based map processing

MÁV had to develop his own GPS
based methodology to resolve data
collection issues
Precision and availability problem
Helicopter based data collection


Cost and time problem
Cost and time problem

 Object hierarchy level – some assets are components of individual object
 Object level - some objects used by all departments
 Attribute level – Different attributes needed for specific objects – General
attributes are needed for all objects

Decentralized operative planning






Quick access to measurement area and knowledge of the territory assured by
local people
Team of local people needed
Local arrangements are needed for access of high risk – railway traffic areas
MÁV has 6 territories for operation management
The operative planning is performed in the 6 territories
Central control is assured by reporting

Team approach




7 different departments
220 different objects
Some hardly visible (on the earth objects)

Limit the need of resources
Preparation of lists for measurements
Basic skills always available + colleagues with special skills if needed

Most expensive error –> repeated measurement needed

Normal data collection
Error correction extreme

Location based remote control







GPS technology based data collection and control
16 groups work remotely over the whole country
Measurement output is strongly related to measurement time
Location of the measurement is important to follow the development
of measurement
FÖMI reporting assures strong control of both measurement time
and measured territories

Upload Challenges






Upload time is equal to measurement time in normal procedures
Automating upload is a performance and quality issue
The measurement and upload is broken down to small cycles – jobs, colleagues
processed 1700 jobs alltogether
150 – 200 jobs were in progress x 7 divisions included in each approval
process, one process is built from 7 steps
Audibility of any processes steps are
needed any time
Task management „umbrella”
supports parallel processing and control

AutoDesk TopoBase and MapGuide based Upload

Expectations for the upload process





Job based
Automated
Minimum manual only for corrections of measurements
Parallel controll of 7 departments
Upload – entirely AutoDesk SW based with AU partner add on

GPS output – limitations of GIS device in data processing


contains all necessary data for processing but not in final – GIS ready - form
AutoDesk TopoBase 2008 based Upload

All postprocesses automatically performed for data adjustments
 Only unexpected corrections have to be performed manually

AutoDesk MapGuide based Job Management

Integrated job management with TopoBase 2008 jobs
 Deadline control and Reporting for job status
© 2011 Autodesk
Documented feedback and controlled time

First level control in 6 territories






7 departments reviewing independently
The uploader is not available at the review
The control of correction has to be simple
The uploader has to wait till all reviews are performed
Task management functionality was introduced with parallel processing capabilities
Central second level support and control

Discussing unified approach
 Controlling unified approach

Processing time control – 8 days for reviews

Usage issues





Organize access to the data
Organize feedback of data quality
Plan for systematic quality improvement
and individual issue handling
Expect unplanned users to come with
unplanned questions
Expect new report and interface requests

Infrastructure management value generation cycle
with GIS

At the moment working at MÁV

Asset Management
 Reporting

All steps can be improved
with location based info - GIS
 Stage by stage approcach needed
to reach full inpact
 Boundaries of each stage have
to be clearly communicated in basic
dimensions:
Business benefits, Data, Functions, Number of Users, Interfaces

Outstanding Results


1 350 000 graphical objects measured
in 14 month
16 times cost saving for data
capturing and upload




Individual employee cost versus
external resource cost – 4 times
savings
Traditional geo-referencing versus
professional GPS – 4 times savings
Quality data – based on MÁV
employees knowledge
„Our data = our system” effect
