Presentation Notes
Engineering geology and geotechnics. The IGC works in geologic and geotechnical studies that give support to public works of construction, tunnels, highways, viaducts Identification and mitigation of natural risks. The IGC takes part in problems of natural risks making studies for the identification and quantification of specific zones of risks Hydrogeology, surficial hydrology and hydraulics engineering. The IGC works in the migration of polluting agents, in the delimitation of flooding zones of the hydraulic public dominion with studies and projects. Instrumentation and networks of control. The IGC implements monitoring services with control networks like indispensable tools that allow lo locate, to predict and to measure the activity of natural pehenomena Applied geophysics. The IGC applies diverse techniques of geophysical prospection that allow to know the disposition and the physical characteristics the materials of the subsoil

GEOLOGICAL MAP OF CATALONIAMain goal of the Geological Institute of Catalonia isto provide to citizens and government withgeological, edaphological and other geo-thematicalinformation to promote the various policies andactions (public and private) focused on the ground,and to establish preventive or corrective measuresin situations of geological risks.
The Decree Law for partial deployment of the IGCdetermines that the contents of the GEOLOGICALMAP OF CATALONIA has to include, at least, thefollowing documents (Geo-Works):
- Geological map of Catalonia (1:25.000)- Geo-anthropic map of Catalonia (1:25.000)- Geological map of urban areas (1:5.000)- Soil map of Catalonia (1:25.000)- Hydro-geological map of Catalonia (1:25.000)- Map of geological hazards (1:25.000)
Presenter
Presentation Notes
A Geological map is a cartographic document, using a topographic map in support, for information about geology, soils and other geological subjects (geothemes). In this map is graphically represented the physical constitution of the soil and subsoil, and many properties of materials that form them.
