The contributed Earth models to EMC are available for download from the model overview pages or IRIS’ Searchable Product Depository (SPUD) in netCDF (network Common Data Form) format. These models are compatible with those desktop visualization systems that support netCDF data files. This page provides a short introduction on installation and model loading for some free Java-based desktop applications that allow 3-D visualization of complex solid earth data.
The IRIS Earth Model Collaboration (EMC) ParaView Plugins
The EMC-ParaView Plugins bundle is set of Python programmable filters/sources to allow ParaView open-source, multi-platform data analysis and visualization application (on macOS® and Linux® platforms) to display EMC netCDF models along with other auxiliary Earth data.
The IRIS Earth Model Collaboration (EMC) 3D Visualizer
EMC’s 3D visualization tool is an open source Python desktop application that uses Python-based MayaVi Data Visualizer 3D application to provide simple 3D visualization capabilities for Earth models.
The UNAVCO GEON Integrated Data Viewer (IDV)
The UNAVCO GEON IDV is a free Java-based desktop application that allows 3-D visualization of complex solid earth data. EMC’s netCDF Earth model data files are GEON IDV compatible and IDV could be used to make complex visualization of EMC’s Earth models, including:
- horizontal and vertical slices (as contour and/or colored by value plots) in any location
- 3-D isosurfaces
- model differences
To view the EMC models in IDV:
Man computer Interactive Data Access System (McIDAS-V)
McIDAS-V is a free Java-based desktop application built on VisAD and Unidata’s IDV and incorporates the functionality of McIDAS-X and HYDRA for viewing data, developing algorithms, and validating results
To view the EMC models in McIDAS-V:
