Topic 2013: Unused potentials of surveying - neglected and new spheres of acitvity


VI. Symposium of Croatian Chamber of Chartered Geodetic Engineers Folie 2


In many European countries professional surveyors have to compete

with other geodesists and increasingly with representatives from other

professions within the core market of surveying.

As a result price dumping is at the order of the day and it takes

ambitious effort to survive. This even applies to Western Europe

where the number of graduates in geodesy and geoinformation for

years falls short of the number of surveying experts needed to replace

retired ones and to occupy new vacant positions within the society.

Nevertheless, the competitive struggle within the established core

market urges us to look out for finding profitable business in niche and

upcoming future markets - off the beaten track.

In Croatia as a prosperous country just having joined the European

Union and having no lack of academic surveyors, a possible predatory

competition thus could be mitigated or prevented.

some fields of action worth investing now




„Green Energy“ – sustainable facilities?

Hexapilots, 2013 Height Tech, 2013




Energy Saving & Improving Mobility (1)

Modern engine control could enable considerable energy saving – in particular for

freight trains - if exact gradient data would be available; alas, this data does not exist

for most of the older railway tracks still in use! Kinematic GNSS surveys by receivers

mounted on engines prove necessary.

System Leader, Knorr Bremse, 2009





Non-availability of absolute railway track data is a common european problem. As rail

position and curvature data often only exists in local coordinate systems or is held

back by „track segment data emperors“, a homogeneous railway GIS is still missing.

Some EU attempts for unified data will come too late – so capable track acceleration

concepts have to refer to cartography or crowd sourcing to explore beneficial track

segments whose redesign would save precious minutes of travel time (Meng, 2011).

New layout concepts using barycentric transition curves (Wiener Bogen ®,

Hasslinger, 1996) can achieve considerable velocity increase on existing railway lines

by advanced track alignment using sophisticated tamper machines. Applied for urban

underground lines in Vienna, small alignments [cms] lead to significant accelerations.

Presle, 1998 Plasser & Theurer, 2013




Worn Infrastructure (road and highway bridges)

Tachymeterstandpunkte

Scan-Bereich

Most of european road bridges become 30 to 50 years now and have been strained

more than designed for because of increasing loads and ever growing traffic. If the

Gigaliner gets operating permission, the situation will even tighten! As economic limits

will not allow for plenty of reconstructions, bridge monitoring will be the only escape!




Evidence in Disasters and Forensics (1)

Ohlmann, 2010





Ohlmann, 2010





Buck, 2009

As long as some

federal offices do not

dispose of necessary

instruments and

experts, private

surveying enterprises

can benefit from

growing demand for

modern accident and

crime investigation.

The Institute of

Forensic Medicine in

Bern (CH) employs

two surveyors,some

LKAs (D) use TLS.




Urban Housing Shortage → loft conversion

Many complex regulations have to be strictly obeyed




Expertise: types of roof timbering, technical terms!




Expertise: what has to be measured and to be pegged?

„On site it will be only assembled what

is fitting together in the computer“

The surveyor‘s job will be to

extract point data out of the BIM

and to translate it for staking out

to put the model into reality! And

it will take a lot of new software,

data storage and accustoming!




Ten important hints




• Listen carefully to the worries of your clients and contractors!

• Read and watch international magazines (looking over the fence)

• Note all your ideas immediately and sort them every week

• Cling to an opportunity to try out the best one of them

• Meet the exact demands; develop and deliver tailored solutions

• Evaluate the outcoming critically and improve your approach

• In case of success go on with a similar or even a larger project

• Overcome apparent limits of your available equipment and staff

• Invest in latest instrument and computer technologies

– Build up joint pools to secure both financial resources and rate of use

• Establish new partnerships to create and share expert knowledge

– Link private enterprise with university institutes and administrative bodies

VI. Symposium of Croatian Chamber of Chartered Geodetic Engineers



The presenter is gratefully indebted to this attentive

audience for listening: Hvala lijepa!

and to

for providing ideas and material concerning loft

conversion and subsequent elevator installation

as well as to the late

who inspired and encouraged us both to think over

new services in surveying and to take another path

- off the beaten track!
