Collaboration

Global Volcano Monitoring Infrastructure Database (GVMID)

• With more than 400 monitoring instrumentation, GVMID can helpCVGHM to improve monitoring instrumentation management.

• The database structure itself is very detailed and comprehensive.

• CVGHM already have data instrumentation management, sotransform all the data into GVMID format will take a lot of time.

• We hope GVMID will have a REST API endpoint, so it will be easier toshare all data using different platform or programming language.

• Regarding of the data contributing and periodically update, CVGHMwill needs further discussion due to institution policy about datasharing.
