Surface Data

This notebook aggregates all the surface data for the FORGE site into a single Open Mining Format (OMF) project file.

Here we load all the surface data and create omf.SurfaceElement objects.

And now create an OMF project file for the surfaces

proj = omf.Project(
    name='FORGE Surfaces',
    description='All surfaces for the 2019 FORGE Geothermal Student Competition '
)

proj.elements = [land_surface,
                 temp_225c,
                 temp_175c,
                 opal_mound_fault,
                 negro_mag_fault,
                 top_granitoid,
                ]

proj.validate()

Save the GIS project file

omf.OMFWriter(proj, gdc19.get_project_path('surfaces.omf'))
