“ Portion of the modelinfo endpoint output providing a summary list of all available shear wave velocity models ( variable=vs) that intersect the region between 25 and 57 degrees latitude ( minlatitude=25&maxlatitude=57). For example, getting a summary list of all available shear wave velocity models ( variable=vs) that intersect the region between 25 and 57 degrees latitude ( minlatitude=25&maxlatitude=57) is as simple as: Python, Perl, Java), command line utilities such as wget and curl or with any web browser with URL identifying the model parameters that you want to operate on. Like all other IRIS DMC web services, irisws earth-model service uses standard HTTP protocol technologies and can be accessed programmatically with a wide range of programming languages (e.g.
/plane-Provides data from a model (in netCDF, GeoCSV format, or as an image) by intersecting the model with a plane./isosurface-Provides isosurface data (in netCDF or GeoCSV format) for selected variable(s) from a selected Earth model./model-Provides data (in netCDF or GeoCSV format) for a model or a subset of a model via clipping and/or decimating./modelinfo-Produces a list (as plain text or JSON) of available Earth models along with a short summary for each.The service offers access, subsetting, or model information for EMC repository models through the following five endpoints (see the Earth Model Web Service Documentation):
Programmatic access to the EMC’s contributed Earth models and reference Earth models is now possible through IRIS Earth Model Web Service. New: model access and visualization via web services These plugins allow users to interact with ParaView to visualize EMC or other netCDF/GeoCSV Earth models in 3D. Visualization of the Earth model in 3D is possible through a set of Python plugins (programmable filters/sources) for ParaView, an open-source data analysis and visualization application. Users can further refine these plots by downloading the corresponding visualization bundle that includes both the model data and the Generic Mapping Tools plotting scripts. In addition to providing access to model data, metadata and references, EMC provides a set of web-based visualization tools to produce a variety of horizontal slices, vertical slices and velocity profiles for model preview.
Model format conversion from netCDF to and from text GeoCSV is possible using the publicly available Python emc-tools. Model access and visualizationĮMC’s model overview pages and DMC’s Searchable Product Depository ( SPUD) model pages, contain information on individual models and provide direct access to model data and metadata under a uniform netCDF 3 format. The Earth model authors are encouraged to share their geophysical models with the research community through EMC (see EMC’s guidelines for model submission). EMC’s Earth model repository currently includes over 70 Earth models (62 velocity, 3 crustal thickness, 7 electrical resistivity/conductivity, 1 attenuation, and 1 temperature) and 9 reference Earth models. The IRIS DMC’s Earth Model Collaboration ( EMC) is a research community-supported long-term repository of Earth models created in 2011 to facilitate sharing, previewing, and accessing various Earth models.
