In archaeology it is very important to rely on a systems that secures the integration of all the data that has been spatially referenced. The archaeological approximation to landscape requires both the obtaining and treatment of this data for being able to carryout analysis , models and representations. GIS has become an essential tool for organizing and processing data obtained from different sources and to establish relations between them.
In
the IVGA project, GIS is an indispensable tool for globally organizing the information, and is specially valuable for advancing in some areas, such as the selection of the emplacements for Roman camps, or the study of the process of mining surveys that were carried by the Roman Empire prior the initiation of the mining labors for the extraction of gold.
The usefulness of any layer of information is only guaranteed if the topographical base on which it woks is precise and has an adequate scale. For this, digital cartographic data basses are used, as well as MDT generated by LiDAR. The elaboration of detailed topographical studies of some sectors is fundamental, as well as the geo-location of certain remains or samples.
During field work, topographic studies are carried out in ancient habitat or mining sectors and their hydrolic network using a total station and a bi-frequency GPS with centimeter-level precision.
