The earth's geometry surface survey may have different levels of detail and resolution. When the access is too difficult, complex in its shape or high definition and detail is demanded, 3D laser scanning is a quick and effective solution whose results can only be conditioned by dense vegetation.
Topographical surveys with information density not achievable by other methods of all kinds of slopes and embankments, caves, quarries, dunes or volcanic areas...
Definition of surfaces with millions of 3D points, from which accurate volumes, high resolution contour lines, profiles and terrestrial metric orthoimagery can be generated.
Isolines of settlements or displacement vectors of surface marks can be generated at a very low cost as compared to conventional surveying methods.
Generation of DTM or DSM TIN models either textured, in vectors, or surfaces, representing the object under study, can be achieved at low cost in few time.

Monitoring plays an essential role in evaluating the structural safety condition of structures.
Time does affect engineering structures, buildings, natural or artificial slopes. Our system can provide spatially continuous or discrete (using materialized points) accurate monitoring, allowing a correct assessment of safety conditions based on reliable data. Our in-house developed methodology provides spatially continuous geometric and semantic data for structural safety analysis.
Mapping and classification of deteriorations is carried out quickly, accurately and at a comparatively low cost, providing much needed information for a correct assessment of safety conditions.
The quality of the information collected using Artescan 's combined terrestrial imaging systems is expected to be better than the information collected during traditional visual inspections in terms of completeness, accuracy, resolution and consistency. Moreover, the information is acquired in a much faster and less expensive way.
This new method of monitoring has been the subject of several presentations of joint communications in expertise international congresses.

Complex structures such as dams, tunnels or bridges can be best surveyed by 3D laser scanning combined with photogrammetry. This method can acquire continuous data throughout the development of the entire structure.
We generate as-built 3D CAD models of structures allowing differential analysis of the project and the final implementation.
Very reliable as-built cross-sections, plans, maps and other sorts of outputs can be extracted anywhere in these accurate 3D models, providing the information needed.
These final as-built 3D models have real value for further structure information systems, where they can be used as the 2D and 3D graphic interface connected with all sorts of other important information especially that related to structure management, safety and planning.

We provide accurate Isometrics, P&I and 3D Modeling & As-built updating services with qualified experienced engineers. In complex industrial scenarios, where thousands of pipes, valvs, machinery and structures are contained in a limited area, our services allows 2D and 3D plant as-built drawings for space analysis for future changes, identifying where spatial and dimensional conflicts occur between the existing structure and one to be integrated.
As-built 3D CAD models can be matched with the 3D design CAD models or with previous recordings of the object under study in order to track building/mounting progress and productivity, assess structural quality and quality control and monitor its safety.
Reverse engineering: conventional technical drawings like cross-sections, plans, profiles, contours, isolines of deformations, maps and displacement vectors, can be extracted anywhere in our 3D models, providing an unprecedented amount of information.

Tangible cultural heritage is often unique and needs preservation. High-resolution architectural surveys create 3D representations from which classification of materials can be carried out and technical drawings can be generated to assist the rehabilitation design.
3D laser scanning, using combined digital imagery, is today the best technique for detailed architectural surveys, aiming at 3D reconstruction, re-engineering and production of orthoimagery.
High-resolution orthophotos from building facades are used for 2D CAD drawing, resulting in reliable technical drawings. The orthoimagery can also be used for interpretation, leading to feature extraction and classification, in construction pathology surveys or material classification analysis.
Accurate and detailed 3D CAD models of classified buildings can be generated, whence plans, profiles, 3D perspectives and cross-sections can be easily derived.

The collected data are an excellent basis for recording and analysis in archaeological studies, and also for the development of animations of missing historical virtual environments.
The use of high-resolution orthoimagery offers archaeologists the required detailed registration, measurements and semantic information for interpretation and studies.
The Institute of Archaeology and Antiquity University of Birmingham, UK: "Laser scanning is changing the ways in which heritage is recorded and understood. It is changing the speed of survey and the quality of the resulting data. It is also providing new archiving opportunities whereby threatened structures really can be recorded virtually for future generations." www.arch-ant.bham.ac.uk

Together with GIS expert partners Artescan has been developing the implementation of Three-dimensional Geographic Information Systems, adding a three-dimensional database to the conventional 2D graphic interface, where each 3D object is independent, linked to an alphanumeric database, and allowing user interactivity. Customized system applications with a 3D interface can be developed.
Accurate 3D data strongly increases the potential of GIS, as it gives a much more reliable visualization, interactivity with the objects and real space analysis. This can be particularly important for the security planning, maintenance, and management of big and complex built structures such as airports, underground metro tunnels and stations, railway stations, factories, oil and gas off-shore platforms, stadiums and big sport halls, tall office blocks, hospitals, hotels, conference centres and exhibition sites.

With our methodologies we can easily reconstruct from laser point clouds, imagery and other existing data, 3D City Model with different levels of detail, including block buildings, textured façades, detailed architectural buildings and terrain modelling.
Urban planning can benefit from the existence of 3D city models as they facilitate the process of analyzing and managing built up areas. Combining these 3D city models with GIS solutions takes urban spatial analysis to a new stage in town planning and managing. The creation of shadow and visibility maps, air and sound pollution propagation analysis, emergency planning and the simulation of disaster scenarios are just a few of the possible applications.
The visualization of photo-realistic 3D model animation of a specific urban area can publicize and promote new engineering or real state projects.
A virtual interactive tour around an on-line 3D city model is an excellent way to promote tourism, showing the places of interest of the area.
