Using the appropriate aerial photographs from the Military Geographical Service of Greece, the Ministry of Environment and Climate Change, the Ministry of Food and Rural Development and the Cadastral and Mapping organization of Greece, it is possible to carry out a photo interpretation study. The aerial photographs are inserted in a suitable photogrammetric station where all orientations are restored, aerial triangulation is solved and digital terrain models, orthophoto mosaics and digital maps are produced.

Photo-interpretation can be a useful tool for documenting a situation as it existed at the time the aerial photograph was taken. The objects that are located and identified during a photo interpretation study have full probative value and legal coverage as, on the one hand, they are represented in public documents and on the other hand, they are imprinted irrefutable elements of reality at the time of shooting.
The photo-interpretation study is framed by the preparation of a technical report suitable for:

Documentation regarding the year of construction of arbitrary buildings or illegal additions, for their further inclusion in Law 4495/2017 / The location of a land plot, the application of titles / For resolving ownership differences and verifying property limits, in case of legal dispute / The proof of the existence or non-existence of roads, trails, streams, etc. / The certificate of existence of a building before 1955, 1975 / For the submission of objections to the National Cadastre in areas where Forest Mapping is complete / For submitting objections to the National Cadastre / For the determination of the boundary line of the seashore etc. / With the use of appropriate software and techniques, the export of measurement information, the production of an orthophoto map, a Digital Surface Model (DSM), the documentation of a geographical location, the sizing or area measurement of a land plot or a building structure, etc., can be achieved. /

The photogrammetric imaging technique called "Structure from Motion" allows the acquisition of information in three dimensions through the collection of a sequence of two-dimensional photographs that differ in position at the time of shooting. With the use of modern aerial and ground photographic media, the three-dimensional capture of a study area, a building structure or an object is achieved. Depending on the object of study, the corresponding equipment is used, from a fixed wing UAV or a multicopter, to a DSLR camera. The science of photogrammetry can produce products and serve in various fields such as:

Creating geo-referenced orthomosaics suitable as backgrounds for any study / Production of 3D colored point cloud / Creating digital terrain and surface models (DTM, DSM) / Cadastral surveying applications for districts, cities, farms / Capturing the existing condition (as built) of building infrastructures and technical projects / Surveys of inaccessible areas / Archaeological sites for the purpose of recording, preservation and restoration / Monitoring of construction works in mines, quarries and construction sites / Mapping of geological formations and monitoring of changes in the terrain / Recording crime scenes and sites of accidents or natural disasters / Managing forest areas / Monitoring and systematic recording of land uses / Mapping of coastal areas etc. /

The most effective and accurate method of 3D mapping is proven to be laser scanner. Our company has the laser scanner FARO FocusS 70, which is characterized by a scanning width of 70 m and is suitable for indoor and outdoor scans. The product produced by a single 3D scan is a point cloud. Properly processed in the corresponding software, the point clouds received from the successive scan positions are aligned with a common reference system and compose the complete point cloud. With further processing, 3D models of real-world objects, architectural drawings, as-built drawings, DTMs, mechanical drawings, etc. can be exported. The data of the laser scanner is the most accurate and correct data for creating a model for using BIM.

Indicative fields of application of the laser scanning technique are the following:

Building information modeling (BIM) for monitoring and management of industrial and mechanical installations. / Capture the existing condition (as built) of building infrastructures and technical projects and integrate future additions using augmented reality. / Preservation and restoration of monuments and archeological sites. / Monitoring of earthworks in mines, quarries and construction sites. / Mapping of geological formations and monitoring of changes in the terrain. / Creation of digital terrain and surface models (DTM, DSM). / Recording crime scenes and sites of accidents or natural disasters. /

The use of BIM (Building Information Modeling) tools is an evolution of the last years that changes the way of elaborating the building studies and the studies of infrastructure projects. In the study stage it enables the exchange of any kind of information between the individual study groups, which is integrated in the model. The model provides the necessary information to make the design and study of buildings and infrastructure faster, cheaper, with better quality and with less impact on the environment. The BIM methodology is an important advantage for the life cycle of buildings, from design to construction, which extends to the renovation of old buildings. In addition, it is possible to produce 3D augmented reality models where the model of the existing infrastructure is augmented using graphics. In this way, it is more effective to consider future infrastructure modifications or further additions.

Depth Measuring using a hydrographic boat equipped with a modern precision sonar instrument. The collected data is used for the production of sonar diagrams and digital seabed models for studies and constructions of port projects, studies of underwater network routes and identification of points of interest (e.g. marine archeology). In the case of port construction projects, altitude data are collected and a topographic survey of the coastal area is carried out.
