Cartographic Standard for Geothermal Information of the Colombian Geological Survey

J. Camilo MATIZ-LEÓN

[SGC, Colombia]

The production of information during surface geothermal exploration, through geological, geophysical and geochemical surface investigations, allows the Colombian Geological Survey - SGC, to model and infer with greater certainty the existence of the resource in areas with geothermal potential in the country. The volume of information compiled and generated, is part of the integration of geosciences that do not have a standard for storage, representation and processing of geothermal data produced and used by the SGC, which does not allow the specialist to have available the data necessary that meet quality and usage criteria that are required. The SGC as state entity and rector of geology in Colombia, has the function of "integrating and analyzing the geoscientific information of the subsoil", which requires guidelines to achieve the design, development, implementation and application of a cartographic standard for geothermal information. This standard will allow the constitution of a policy of simplification of processes for the storage and representation of information for each exploration area with geothermal resources in the country, positioning the SGC as the entity in charge of managing the geothermal information raised by future operators that exploit the resource. The components of the standard correspond to a geographic database to store the raster and vector information, which include data from geological units, samples, structural, geophysical stations (gravimetric, magnetometric, magnetotelluric, shallow temperature surveys, vertical electric surveys), geophysical anomaly grids, geochemical data (springs thermal, fumaroles), among others. It also includes a catalog of symbols that stores the representation of each object (data to be represented), a catalog of texts to represent the annotations, a catalog of objects (geometries and grids) that describes each object and a data model to identify the type of data to be represented.
