You can view the borehole points in a gINT project as Google Earth places, and visualize your site layout using all of Google Earth’s tools.

Google Earth integration is provided in gINT 8.2. With this feature, you can view the borehole points in a gINT project as Google Earth places, and visualize your site layout using all of Google Earth’s tools. You can have the borehole points represented with custom place labels, label colors, icons, and popup descriptions, all obtained from fields in the POINT table or tables with 1-to-1 relationships with POINT.

For gINT point data to be interpreted as Google Earth place data, fields must be present in the POINT table (or a table with a 1-to-1 relationship to POINT) that supply the latitude and longitude coordinates. Here are some possible ways to implement these fields:

You specify mappings between fields in the gINT table and Google Earth by selecting Additional Modules > Google Earth > Google Earth Setup, then selecting fields.

You launch Google Earth from another menu option. Google Earth opens with the current project’s borehole points identified with pushpin icons and the borehole numbers alongside each:

Point icons and labels can be customized based on borehole type or other criteria.

Using gINT Rules programming, a popup can be automatically created for each point. The popup can contain a description that has been assembled from various POINT table fields (including elevation, depth, water level, and hole inclination) and even some LITHOLOGY table data (bedrock depth and elevation).

Also a hyperlink can be included in the popup that opens an Adobe Acrobat window displaying the borehole log PDF for the borehole.

An example gINT Rule is freely downloadable from this WIKI: gra008.zip (requires v.8.2.003 or later).
