Ultra-high resolution digital photography
Ultra-high resolution imagery (up to 2cm Ground Sample Distance) is available in RGB and NIR wavebands. We can provide ortho-rectified imagery with an unprecedented level of detail.
Thanks to Lidar surveys it is possible to obtain various products, including digital terrain models (DTM) and digital surface models (DSM).
The term DTM refers to the mathematical representation of the physical surface of the earth by means of a grid of points which are plano-altimetrically determined. The DTM is derived from the digital surface model (DSM) detected by means of the Lidar technique, by removing all objects present on the ground which are not significant for the determination of the plano-altimetrical and morphological asset.
In operational terms, the DTM can be materialized with an irregular triangular grid surface (triangulated irregular network, TIN), or regular grid (GRID).
Multiple sensors are used being provided by trading partners. Through the use of a rangefinder laser, the modern technology of laser scanning allows to create digital terrain models and 3D models of urban and suburban buildings. Point clouds are classified automatically with powerful software instruments.
3D city models
• Land surveys: Photo Surveys of Matrix Centers facades
• Data processing: 3D city models
• Data processing: Building of road profiles
Activities such as planning, management and design on and of the territory, do need a detailed analysis and simulations are required which are realistic both from the aesthetical and from the geometric point of view.
Especially when scales of greater detail are elaborated, 3D modeling meets all these requirements as it comes from a photogrammetric mapping acquisition with the support of the photographic survey with ground operator.
Thanks to the long experience, Aeronike has studied the development of 3D technical drawings which are highly innovative and versatile, both in management as well as in later use, deriving from the integration of photogrammetric digital planimetrical survey images (subsequent frames with stereoscopic coverage) and photographs obtained by means of an esacopter drone. By means of this process, even larger areas can quickly be covered with metrical accuracy and a detail equal to the cartographic one. Further applications of the final product can be: the inclusion in a GIS system for finalizing the 2D territorial information, environmental impact studies, surveys of caves and archaeological sites, and even the promotion of the area for touristic scopes with the possibility to navigate the area through the web.
In an improvement and simplification perspective of engineer’s work, one of the major challenges is to achieve the production of smart cities 3D models which are able to furnish increasingly complete and exhaustive information about buildings and about the territory in general, by gathering in its inside various databases going from the strictly urban ones to the technological networks, cadastral, taxes, and cultural heritage ones.
Digital terrain models
We can create three dimensional computer Digital Terrain Models (DTM) and Digital Surface Models (DSM) using our cutting edge setereo imaging and Lidar systems.
We operate a multi-spectral RGB-NIR (Near Infra-Red) camera, capable of capturing imagery in all 4 bands at up to 2cm GSD. At its simplest the NIR data can provide clear delineation and quantification of vegetated and hard surfaces. However, the multispectral data also allows for the production of various vegetation indices such as the Normalised Difference Vegetation Index (NDVI) – a key index for monitroing vegetation vigour. NIR data is often useful for mapping vegetation extent, invasive species and looking for areas of tree and vegetation stress.
Our thermal camera system integrates high-end technology with a survey grade GPS positioning system enabling the derivation of accurate thermal maps of the earth’s surface. The camera has a thermal sensitivity of <0.05°C, which ensures any subtle differences in surface temperature will be evident in the data stream. Where other thermal cameras only display relative temperatures across a scene, our system produces actual temperature readings for objects of interest. Our thermal sensor has been deployed to map plumes from power stations, water treatment and reservoir outflows and to identify leaks in pipelines as well as more standardised building heat loss assessments.
We are able to undertake vertical and oblique, High-Definition video surveys in our aircraft. The HD video provides stunning visualisation of the environment from above.

Expert data analysis and consultancy services
EuroMed Mapping offers high quality image analysis for a wide range of services, including digital terrain maps, digital landscape modelling, cartography, bird and animal surveys and infrastructure monitoring and route analysis.
Our staff are some of Europe’s most experienced analysts and digital cartographers, who together have analysed tens of thousands of images. We work with industry and regulators across a very wide range of sectors, but especially the water and power industries.
Gamma-ray spectrometric surveys measure the radiation of one or more natural radio-elements, such as potassium, uranium, thorium, or a specific man-made radioelement.
Magnetic and Gamma-ray systems are usually installed together on same airborne platform for a multi acquisition flight mission.
Airborne surveillance surveys
The last frontier in the environmental observation field are multi-sensor remote sensing and aerial surveillance systems.
With these sensors Helica is able to provide high-resolution and definition (HD) imagery , both in the visible (RGB) and in the thermal infrared (IR) part of the electromagnetic spectrum.
The imagery can be recorded on board or broadcast in real time to the ground, at a distance of up to 250 kilometres, using a downlink HD system. This airborne system allows the visualization and display of the airborne surveyed area, placing and overlaying the georeferenced imagery on a geographic database.
Airborne geophysical surveys
Airborne geophysical survey is a process for measuring the variation of several key physical or geochemical parameters of the earth.
The most important parameters measured are conductivity (which is the inverse of resistivity), magnetic susceptibility, density, and radioactive element concentration. The airborne systems used by EuroMed Mapping to measure these parameters are a magnetometer and a gamma-ray spectrometer (AGS).
Magnetic surveys map the three dimensional variation in conductivity, caused by changes in mineralogy, pollutants, water content or salinity, among other causes. Airborne magnetic surveys map the variation of the magnetic susceptibility, generally due to changes in the magnetite content of the rock.
We have a large team of analysts ready to meet your mapping requirements. We use a range of GIS software that we fully integrate with our aerial mapping service.
We have carried out aerial surveys across the globe for a variety of environmental purposes from the enumeration of seabirds around the British Isles and Europe to mapping vegetation communities in the Everglades. Our remote sensing assets have been used to provide aerial based solutions in often inaccessible, dangerous and/or diverse locations from the Scottish highlands to remote Hawaiian Islands.
Our ultra-high resolution aerial surveys have been used for a variety of ecological mapping purposes including; the identification seabirds and marine megafauna as part of Environmental Impact Assessments for proposed, consented and existing offshore wind farms; the identification of invasive species such as Himalayan Balsam; the derivation of land-cover maps; and the definition of habitat boundaries.
Our high resolution camera systems enable us to undertake wildlife populations surveys including birds, marine mammals, large terrestrial mammals as well as habitat surveys for a range of environments.
Our fleet includes specialist observer aircraft with excellent visibility, providing an ideal viewing platform for observational surveillance. Our aircraft are also modified to allow a variety of surveillance monitoring equipment to be installed.
Linear infrastructure mapping e.g. pipelines
Our aircraft and camera systems allow for extensive linear structures such as pipelines, cable routes, roads and railways to be mapped quickly and efficiently.
Change detection in the built and natural environments
We are able to map changes in the environment over time with repeat surveys and specialist software. Applications include monitoring river erosion, land slippage and monitoring progress of construction projects.
The last frontier in the environmental observation field are multi-sensor remote sensing and aerial surveillance systems.
With these sensors EuroMed Mapping is able to provide high-resolution and definition (HD) imagery , both in the visible (RGB) and in the thermal infrared (IR) part of the electromagnetic spectrum.
The imagery can be recorded on board or broadcast in real time to the ground, at a distance of up to 250 kilometers, using a downlink HD system. This airborne system allows the visualization and display of the airborne surveyed area, placing and overlaying the georeferenced imagery on a geographic database.
A DTM representing areas which have been flooded, or are at risk of flooding, is fundamental for the control of morphological changes in stretches of rivers and coastal zones.
Airborne laser-scanner products allow detailed, quick and low-cost surveys of vast areas to be made, even during or immediately after flooding. In particular, the analysis of aerial photographs and the comparison between laser-altimetric surveys and orthophotos obtained before and after a flood allows the main morphological changes produced by flooding to be verified and analyzed, whether for insurance, flood relief, or planning future mitigation. Furthermore, it is possible to accurately estimate the volumes of sediment moved by floods and extract data which is essential for the evaluation of stability conditions in the area.
The assessment of the conservation state, of the evolution and of the dynamics of the environmental system is essential not only for the protection but also for a correct management and environmental planning (i.e. dendrometry calculations for the forestry field, studies of the terrain and monitoring of the basins for geology etc.). The survey aimed to the environmental analysis is important to display and to assess possible critical areas in the region that can also be analyzed with periodic acquisitions of morphological data aiming to deliver information on the effectiveness of the interventions.
