ROAD CADASTRE

Vectorization is the process of abstracting the real world into spatial elements represented by points, lines and polygons geographically referenced in a coordinate system.

The vector data are then used for the analysis of discrete (discontinuous) objects such as roads, buildings, land or power lines. The boundaries of the objects are precise and clear and the surfaces can be calculated. The representations provided by Helica are compatible with the major 3D design and analysis software.

FOR MAINTENANCE AND UPDATING OF THE ROAD CADASTRE, THE USE OF LASER-SCAN ALTIMETRIC DATA ASSOCIATED WITH DIGITAL ORTHOPHOTOS MAKES IT POSSIBLE TO:

Define the surface characteristics of the asphalt, identifying areas in need of maintenance;

To establish the plano-altimetric trend and the geometric characteristics of the road and of the artefacts in site, even in wooded areas;

Check the horizontal and vertical signs using very high resolution digital orthophotos. Also, the LiDAR airborne system offers excellent integration with the laser data detected with the Mobile Mapping System. The combination of the two datasets in fact allows to have a relief virtually free of shadows.

PHOTOGAMMETRY

Helica performs high resolution photogrammetric surveys with medium and large format cameras, both for airplanes and helicopters (also in combination with the LiDAR sensor).

Surveys can be targeted to the realization of orthophotomosaics and their derivatives, for example vectorization of elements for the update of topographic databases.

The PhaseOne iXA-180 camera is ideal for combining laser scans and therefore to provide a product to support the interpretation of the point cloud.

The Vexcel Ultracam Eagle, mounted on an airplane, is able to record 4 bands of color (RGBI) and is therefore ideal for environmental, forestry and agricultural monitoring projects. Also for the analysis of environments with high population density and large extension (even thousands of square kilometers).

GEOPHYSICS

High-resolution geophysical surveys are the new frontier in both geological and environmental mining.

The new standards of GPS precision and the evolution of magnetometers and spectrometers allow to obtain significant improvements in the restitution of maps. Geophysical surveys are useful for gaining additional and possibly game-changing information on areas that were studied with older or obsolete techniques.

Moreover, the relatively low costs makes aerial geophysics particularly interesting in the early stages of exploration, both mining and geological.

The possibility of analyzing large areas in a short time optimizes the possibility to concentrate further and more expensive investigations on areas that are considered promising.

ENVIRONMENTAL
MANAGEMENT

Understanding the state of conservation, how the environmental system evolves and the dynamics of it, is essential for protection but also for proper land management and planning (e.g. calculation of dendrometric volumes in forestry, studies of soil movements and monitoring of river basins in geology, etc.).

The survey targeted at environmental analysis is fundamental for identifying and assessing any critical issues. The critical zones can be further analyzed through periodic acquisitions of morphological data in order to provide information on the effectiveness of any interventions.

HYDROGEOLOGY

The use of laser scanners gives Helica the double advantage of being able to provide accurate models for hydrogeological planning and to be time efficient and precise in responding to emergencies and catastrophic events (earthquakes, floods, etc.).

Typically the airborne system is particularly suitable for:

- Emergency surveys, designed to monitor areas affected by disasters, thus avoiding the use of operators on the ground;

- Monitoring of critical situations also by comparing acquisitions made before and after the event.

POWERLINES

The airborne laser scanner is the tool that better fits the requirements of the powerline sector in terms of planning, designing, management and maintenance. Using helicopters, the surveys are carried out quickly on any terrain, without being conditioned by its morphology.

The integration of digital models with the acquired images allows:

- The classification of the power towers and pylons;

- The vectorization of catenaries;

- The determination of safety areas around cables and towers;

- The development of models of electromagnetic fields distribution around the power lines, close to populated areas;

RESEARCH
& DEVELOPMENT

Helica is constantly looking for new technological and innovative solutions. This has allowed us to offer a more complete range of products to meet all customer needs.
