I am conducting a study to locate an adequate material I need for a cover of a waste rock dump. I have many boreholes in an area of interest, and I want to generate a fence diagram of the boreholes relative to one another and eventually use my data to develop cross-sections. Can I do this if I import google earth easting/northing UTM coordinates into gINT? I have the gINT professional software.
I can refer to the help document Bently supplies to figure out the logistics of inputting data from Google Earth to gINT, but before I use a lot of time translating logs to gINT I want to make sure I can generate what I want.
Thank you,
Madison
Not exactly clear what you are asking for but maybe this will help
Gint can generate fence diagrams/ crossections with graphical logs of borings to scale positioned vertically and horizontally relative to each other. Borings will be projected in to the fence line based on the location of the boring and fence line. To do this gint needs the following:
Material vs depth information defining the materials encountered in the boring (ie the boring log) this does not come from Google earth
The horizontal and vertical location of the top of the boring. This can be defined by any rectangular coordinate system you want. If you have surveyed coordinates that is great. If you want to pull UTM coordinates from borings spotted visually in goggle earth that will work. You could even use lat. and long . if you build in a correction for the change in distance between longitude lines with latitude. Note that elevations obtained from Google earths terrain model can be significantly in error.
A gINT fence template that tells gINT how you want the borings to look. GINT has a number of pre built templates that may suit your needs. Take a look at them. Note that templates are stored in a library file that you can select. Also note that the different templates may use a different data structure so you need to decide on a template and data structure before you start inputting data.
Gint will generate fences from borings you select or along alignments that you input. If you want to plot the ground line on the fence you will have to input distances and elevations along the alignment. gint can also generate the ground line if you import a terrain model.
This is a very brief summary of the process. There are many many details that I did not discuss.
If this is not the information you are looking for please clarify your request.
This is exactly what I am looking to do, thank you! Are there training modules to assist me in this process or any other resources you know of?
I have utm (in both meters and feet) and elevations of most of my boreholes from GPS points taken during drilling, so I can input those directly. When I do that, I do see a discrepancy between the distribution of boreholes between google earth and the ones plotted in gINT. It almost appears like it might be a mirror image of the borehole distribution in Google earth. Do you have any idea why that may be?
There are numerous tutorials in this forum under the wiki here:

There are also many other resources located within the wiki and files portion.
The 2 most common causes of "mirroring" are as follows.
1) Not understanding that google earth and many other software solutions treat western hemisphere longitude as negative ie 70.2345 degrees west is -70.2345 degrees. Thus longitude increases as you move to the west. Some conversion software (CORPSCON is one) treat western longitude as positive. UTM coordinates are forced to be always positive by defining the origin of the coordinates in each zone with large positive values. Thus they always increase to the north and east. If you are switching in and out of software or portable GPS units you have to understand what conventions they are using.
2) Mixing up northing and easting during input because the order of northing and easting is different than longitude latitude or Cartesian x and y axes. This mirror and flips.
