INTERNATIONAL PARTNER BÜRO S.R.L. was established on 23 March 2007 and specializes in

Geodesy, Surveying Engineering, UAV Photogrammetry and 3D Laser Scanning.

International Partner Buro S.R.L. is an innovative, serious company, offering a wide range of

topographic and geodetic services, encompassing a large and varied market.

We are one of the most representative companies when it comes to 3D laser scanning and surveying

services in Romania.

The focus is always on quality, which to us is the sum of several factors such as:

Professional training of our engineers.

Through training and refresher courses on new technologies and software solutions appeared on the

market and deployed in our company we are always in front of the competition.

Punctuality is what we are when the project’s deadline arrives. We are always trying to improve the

efficiency of the methods used in a project. This manifests as lower costs for our customers.

Accuracy refers to the survey instruments that we use in the measurements included in projects and

to the work of maintaining them in the correct parameters. We always perform regular checks on the

instruments that we have.

I participate with employees from the management team at international exhibitions like INTERGEO in

order to obtain innovative information that we could apply to projects we have in progress and to

future ones.

We also have our own methods of research and testing that have resulted in improved accuracies

and lower execution time.

International Partner Buro SRL is a friendly, customer-oriented company which adds quality to all

projects in which we are involved.

International Partner Buro is the office (Buro) in which you will find the ideal partner (Partner) to

perform quality topographic works not only in Romania, but also internationally.

We are committed to building companies, multinational corporations throughout the world, but also to

the state institutions and governments that need our specialists.

STATISTICS

Given the need for lower costs for implementation and maintenance a new

technology emerged, more efficient not only economically but also from the quality point of view.

UAVs can be seen as a supplement or replacement for terrestrial photogrammetry

and related areas such as topography and cadaster.

Compared to other technologies, the UAV provide large coverage in a short time (100

ha/hour) and a range of precision distributed between a few inches and a couple of meters,

depending on the desired product.

STATISTICS

UAV photogrammetry can be perceived as a new tool or branch of classical

photogrammetry. UAV opens new perspectives in the field recordings made from small and

medium distances, but also represents an introduction to new alternatives.


RPV, DRONE, UAVRPV, DRONE, UAVA RPV or Remote Powered Vehicle is the airplane model characterized by its need of

constant feedback from the permanent ground station in order to keep on flying.

The RPV drone is similar except that it follows the ground controls while being in flight, or uses the

pre-stored flight plans stored in memory.

UAV or Unmanned Aerial Vehicle is a drone acting at great distances, operating primarily under

preprogrammed autopilot.

WHAT IS A DRONE?

JOURNEYJOURNEYIt is a model airplane, made after a particular design, with dedicated remote sensing

system (multispectral sensors from HD video camera to thermal and IR) equipped with launch and

parachute systems for takeoffs and landings in area that wont allow for a glided landing. Composite

materials used in its construction (fiberglass, carbon, kevlar) provide protection and allow working

even in moderate rain.

Control is achieved either by default flight plans, either manually via telemetry in real

time. All real-time images are transmitted from the on board system to the ground. Although it is an

alternative technology, all the problems and restrictions are successfully completed in this model.

Payload limitation, non-metric camera calibration, automatic route flight planning based on a

navigation system via waypoints, constraints on the need for stereoscopic recordings, flight

management, onboard sensors and safety and legal aspects are satisfied.


With the evolution of technology the need for more precise information obtained in a

short time over a large area increased.

The UAV technology can get the data even from area that were previously regarded

as dangerous or inaccessible. We have the ability to make measurements from a safe distance

without the risk of accidents.

The hexacopter can go where no measurement tool can reach, taking a variety of

data types.

Journey can fly under the flight ceiling imposed to platforms specific to classic

photogrammetry. This allows acquisition of images that satisfy all needs. In this way the time and

execution costs are reduced.

We offer an alternative to traditional means, our advantages being: short execution

time, high level of details, lower costs, high temporal, spatial and radiometric resolution. This type

of information is only available using one of the two UAV alternatives.

Our products serve a wide range of industries and are customized to customer

needs.

OUR VISION


ACCESIBILITYACCESIBILITYWith the help of UAV technology we can penetrate inaccessible areas, difficult or

dangerous for human operators.

SAFETYSAFETYProtection of personnel by performing measurements from a safe distance.

NONINTRUSIVENONINTRUSIVEMeasurements are made in a noninvasive manner, leaving no traces or emissions of

any nature during or after flight.

SPEEDSPEEDMeasurements are made in a short time and with high temporal resolution.

HIGH AUTONOMYHIGH AUTONOMYDue to its slow flight speed and possibility to glide, combined with a scheduled flight

path, you can study areas of interest covering relatively large areas.

ADVANTAGES


FLIGHT PLAN

AUTOPILOTAUTOPILOTSeamlessly integrated with the aircraft, can accurately meet predetermined flight

plan, controlling the camera so as to obtain coverage over the entire studied area.

FLIGHT CHARACTERISTICSFLIGHT CHARACTERISTICSFrom one UAV flight, we can provide data for an area over 30 sq. km. depending on

the required resolution, shape and characteristics of the studied zone.

With faster processing compared to the conventional methods, one can obtain

various products.

Thematic maps are based on images taken using UAV technology in a wide

spectral range (thermal infrared, color infrared, visible RGB), data taken from different sensors,

3D laser scanning and existing analog plans. Interaction between land surface and any factor of

influence can be represented in the form of thematic maps. Their establishment is based on

theoretical principles applied in an ideal context. An example is determining the amount of water

accumulated in micro relief regions. Wind effect based on obstacles in the region (mountain

peaks, forests, valleys). These thematic maps can be made at all stages of the project be them

initial, intermediate or final.

This can highlight the interaction between the new elements appeared in the field,

interaction that could explain different phenomena (landslides, floods).

Further analysis can be performed based on cameras recordings in thermal

infrared. Noise maps are other products with utility in studies of the environment.

For those who practice aerial archaeology, research has shown that the recordings

captured during observation flights in some areas, and study of earlier aerial photography allow to

identify vestiges of the past before they are irretrievably lost. Some of the factors that may cause

such levels of degradation are urban development, population growth, intensive agriculture and

other more aggressive interventions on the natural environment.

In western countries, air investigative programs are going on for decades for the

purpose of photography and mapping archaeological sites and historic landscapes. This process

provides a wealth of information for understanding cultural heritage and for developing strategies

and policies for protection, conservation, restoration, management and enhancement thereof.

It depends on each country to develop its own programs for aerial photography in

order to complement archaeological maps. This includes not only individual sites from prehistory

nut also modern time ones and cultural landscapes covering large areas, especially those

threatened by rapid changes in infrastructure caused by industrial, settlements or agricultural

expansion.

Problems are easily highlighted in the images taken by the drone, problems that otherwise would

have passed unnoticed from the ground because of the difference of perspective.

during the flight recordings are made in HD video or photo. The ground station receives these

recordings in real time and can provide drone perspective. During this operation all personnel

are on ground eliminating thus, any risk.

MOSAICSMOSAICSIs a product that can be obtained thanks to the high degree of overlap between

images (60-80%). More precise, it is a graphical representation of the entire area of interest. In this

form, the mosaics are used as support. It also has use in spectral analysis stages. For example in

vegetation studies: health, stress, vegetative stage, species, age, all can be determine from a

mosaic.

Their high temporal resolution allows for a more rigorous management of the area

from conservation and evolutionary point of view. This way, highlighting potential problem areas is

done more easily and efficiently. Mosaics allow the study of virtually any area of interest up closely,

without the need for local intervention.

ORTHORECTIFIED MOSAICSORTHORECTIFIED MOSAICSIf you want to extract more information from these graphic products, such as metric

measurements, the original mosaic have to be orthorectified. Based on the DSM, the terrain

configuration effect is reduced. The errors and possible variations due to lens or camera type are

also removed.

These final products can serve not only as support for site plans, but also as a source

for them.
