Warning

This manual contains the documentation for DCIP octree package releases beginning on 2020-05-08. This version of the package is compatible with GIFtools v2.31 and later. If using an earlier version of GIFtools, please see the 2014-10 release manual .

5. Examples

Here, the program libraries for DCIP octree will be used to:

  • create an OcTree mesh based on the survey

  • construct block models on OcTree meshes

  • DC and IP data for conductivity and chargeability models, respectively

  • create interface weights

  • create sensitivity weights model

  • invert DC and IP data to recover conductivity and chargeability models, respectively

5.1. Surface Data Example

In this example, we simulate and invert DC/IP data with survey/observations files that are in surface format . That is, electrode elevations are not included in the survey/observations files and we assume all electrodes live on the discretize surface topograpy.

5.2. General Data Example

In this example, we simulate and invert DC/IP data with survey/observations files that are in general format . That is, elevations are included in the survey/observations files. However, we must ensure that any electrodes located within air cells are projected to the discrete surface so they are not modeled as living in the air.
