Geographic Information Systems (GIS) technology has been developed to respond to the requirements of complex spatial data management and has numerous applications in a broad professional domain. GIS applications have radically increased during the last decade, and are now an integral part of operations within many productive sectors, government agencies and administration in general, citizen services etc.

Roikos S.A. provides integrated services in cartography, mapping and development of GIS solutions for a variety of applications, such as environmental management, organisation of public services, management of infrastructural works, e-government for citizens support etc. Furthermore GIS applications are extensively used in the conduct of many studies (eg. Town Plans, spatial planning studies, cadastral mapping, hydraulic engineering studies, environmental planning, utilities design etc).

Our highly qualified GIS experts are trained in using various, widespread standard GIS software packages including ArcInfo, ArcView, MapInfo, AutoCAD Map, Oracle g and others. Also, Roikos S.A. is equipped with modern, state of the art GPS apparatus (Global Positioning Systems) which provide real-time and accurate measurements that may be referenced in various geographic positioning systems.

Roikos S.A. provides services in all fields related to topographic studies and surveys, such as:

• Land Information Systems
• Cadastral surveys
• Topographic, Hydrographic, Geodetic and Geophysical surveys
• Digital cartography and mapping, digital elevation modelling
• Digital Photogrammetry, Photo-Interpretation and Remote Sensing

To ensure the highly sophisticated and qualitative delivery of services, Roikos S.A. is investing considerable amounts on an annual basis and owns a set of technologically advanced surveying instruments (laser and optical total stations, imaging stations, theodolites, levels etc), as well as the most updated and reliable, related software available. Moreover, the company has developed a state of the art, customised software platform (ROIKOS-KTHMA®) dedicated to facilitate the management and organisation of land information and registration systems and databases.

Typical projects:

• Topographic surveys, measurements and mapping of high accuracy and robustness, for a large number of projects on transport systems, hydraulic engineering and environmental management.
• Production of digital maps from high accuracy satellite images, for a variety of project applications (urban and spatial planning, town plans, etc).
• Photogrammetric survey of the Venetian salt warehouses in the Corfu Island.
• GIS applications for a variety of projects (land register, town planning, environmental management studies, water supply networks and gas supply networks, aerials and towers for mobile telephony etc).
• Land Information System (cadastre) for the cities of Alexandroupoli, Drama, Xanthi, Kilkis and Polygyros.
