📋 Tender Overview
The Geological Mining and Metallurgical Institute Ingemmet announced that the National Geological Chart at a scale of 1 50000 is integrated and published in an 80 geodatabase format which is made up of the integration of 853 maps. The process of integrating the 50k geological maps began with the migration of 853 sheets from the PDF formats shapefile to the geodatabase format for the efficient storage and management of a large amount of data at the national level. Once the basic information had been migrated labels and color codes of the various stratigraphic units were standardized. Later lithology and age attributes were entered along the entire coast and mountains. Subsequently the correction of the junctions between maps was carried out and finally with the use of programming tools for the use of machine learning techniques. The integration of 853 maps required an intense processing of geological information complemented with the interpretation of satellite images for a period of almost six months. The integrated map is the product of the teamwork of Peruvian geologists from Ingemmet with experience in geological mapping and digital geological mapping who together made the integration of the immense national geological information a reality. The digital data is backed by database extracts that allow the user to make inquiries. For example querying a rock type displayed on the digital map returns information about age petrology and relationships to other rocks. In the GEOCATMIN an integrated 50k geological map layer users can view query and manipulate map information. Users can take data to the field on a laptop or tablet or explore geology from the comfort of their home rather than on a paper map.
