OGC WFS event parameters web services

The ASMI OGC WFS services provides access to the latest CPTI catalogue.

Data citation of the current (i.e. latest) version of CPTI:

Use OGC web services in a GIS

The OGC standard is well supported by GIS software such as ESRI ArcMap and QGIS.

ESRI ArcMap is not able to load a WFS layer without a "Data Interoperability" license.

QGIS supports natively the OGC WFS standard. Show how to load a WFS layer into QGIS

Query examples

Here you may find some example of the possible queries offered by OGC web services.
Please, refer to the corresponding manuals at OGC WFS for a complete overview of their standard.

Web service capabilities

Features description

Request a specific earthquake using the AHEAD event ID

Request all earthquakes having magnitude (Mw) greater than 6

The WFS has GML as the default format for encoding data. If you would like to obtain a result encoded using a different format, you may add the parameter "&outputFormat=".

Here the list of supported output formats:

  • csv, excel, excel2007, gml2, gml3, gml32, json, kml, shape-zip
