[00:00:07.690]on how to incorporate and snap

[00:00:09.830]to geological mapping data in Leapfrog Geo.

[00:00:12.810]This is building on a blog

[00:00:14.650]that was written on our website back in September.

[00:00:17.720]So if you’d like to read in more detail,

[00:00:19.790]you can jump online and have a look.

[00:00:25.220]To go through this workflow,

[00:00:26.270]I’m going to be working in Leapfrog Geo.

[00:00:29.631]In Leapfrog Geo here,

[00:00:30.464]you can see I have a vein interpretation

[00:00:32.223]that is built off drilling data.

[00:00:35.580]I also have a set of mapping data

[00:00:37.800]that has been collected in the field.

[00:00:40.250]This consists of X, Y, and Z locational data

[00:00:45.000]and two category columns.

[00:00:49.030]The classification here has been broken up

[00:00:50.750]into hanging wall and foot wall contact points

[00:00:54.750]and we’re going to use these

[00:00:57.080]to update the interpretation in the Geo model.

[00:01:03.440]So the first step to be able to update a vein

[00:01:07.190]with mapping data is to put in the data into our project.

[00:01:11.790]To do this, I’m going to come to the points folder,

[00:01:14.090]I’m going to right click, and I’m going to bring the points in.

[00:01:18.075]I’m going to bring in the mapping points,

[00:01:20.936]I’m going to make sure my columns are selected correctly.

[00:01:24.010]So in this case, I need to make sure my elevation is flagged

[00:01:28.130]and I want to bring in the data here as category.

[00:01:36.060]We can then have a look at this data in the seen view.

[00:01:41.530]So you can see here, we have three elevations.

[00:01:51.710]And we have a foot wall dataset and a hanging wall dataset.

[00:02:01.540]And what we want to do is use these points

[00:02:04.310]to update the interpretation.

[00:02:06.400]So you can see when we look from above here

[00:02:08.820]that some of my hanging wall data

[00:02:10.630]suggest that this vein should be coming further out.

[00:02:15.010]So what we’ll do as a first step,

[00:02:16.750]so we’re going to have a look at how this mapping data

[00:02:18.480]impacts our interpretation, we’re going to take a copy.

[00:02:21.360]I’m going to extract my mesh

[00:02:24.900]and we’ll come back to that one later.

[00:02:30.230]Now to update the vein in particular,

[00:02:32.790]we need to focus on the objects that make that vein.

[00:02:36.270]So in this case, I’ve expanded my Dyke 1

[00:02:38.950]and I’ve come to the different objects

[00:02:41.200]that are used to build it.

[00:02:43.130]I want to change the hanging wall and the foot wall

[00:02:45.430]based on the data portion of the project.

[00:02:48.480]Now at the moment I can’t do that

[00:02:49.740]because all the data is contained within one file

[00:02:52.310]and there’s no way within an edit down here

[00:02:55.390]that I can differentiate between the hanging wall

[00:02:57.860]and foot wall.

[00:02:59.030]So to do that, I need to separate this data.

[00:03:04.400]So I will right click and create a new selection.

[00:03:09.370]So my new selection’s going to be built off a query,

[00:03:12.190]and that’s going to focus on the classification column

[00:03:14.640]that I imported and where it is equal to the foot wall.

[00:03:21.940]I’m going to create a foot wall contact dataset.

[00:03:29.520]I can repeat the process here with the hanging wall.

[00:03:31.900]So I’m going to create new selection, and new query

[00:03:35.820]and again, look at the classification column

[00:03:39.700]where it is equal to hanging wall,

[00:03:45.193]and we can call that hanging wall contacts.

[00:03:50.010]Now if you don’t have those classifications

[00:03:51.870]in your data set to begin with,

[00:03:53.840]you can always create a new category selection

[00:03:56.690]from the imported data,

[00:03:58.409]and you can go and update this in the same view.

[00:04:03.320]But now that I’ve split my data out, we can have a look.

[00:04:07.270]So if I load just my foot wall contacts on,

[00:04:10.600]I can see that I’ve split that data

[00:04:12.210]into a foot wall data set and if we load the hanging wall,

[00:04:18.840]it appears on the other side.

[00:04:24.860]So to have this data, the first step is to come down

[00:04:28.870]to the objects themselves.

[00:04:32.780]Now in this case, we’re going to go to the hanging wall,

[00:04:35.740]we’re going to add data and add the points.

[00:04:39.470]Because I’m working on my hanging wall surface,

[00:04:41.120]I want to add the hanging wall contacts, I click okay.

[00:04:45.430]And that will start to reprocess my vein

[00:04:48.800]and the rest of my model.

[00:04:51.490]I can repeat that for the foot wall.

[00:04:53.700]So while this is running,

[00:04:54.930]I’m going to add the points to my foot wall contact as well.

[00:04:58.080]And what we should see is, as this starts to process,

[00:05:01.870]the vein will change based on that mapping data.

[00:05:05.820]So let’s make those points a bit more visible.

[00:05:16.470]So here you can see the vein surface

[00:05:18.410]has now come out to try and honor those points.

[00:05:21.310]However, at the moment it is using them as a guide,

[00:05:24.490]but it is not snapped.

[00:05:25.690]So you can see the edges of my triangulations here

[00:05:27.800]are not snapping to my data points.

[00:05:31.140]So if I want to make sure that my vein interpretation

[00:05:33.940]is also snapped, I need to come back to my dyke down here,

[00:05:38.510]double click, and initially go to surfacing.

[00:05:43.000]In the snap to data, I have changed it to custom.

[00:05:48.050]Yours may often be set to drilling only.

[00:05:52.270]Once I’ve set it to custom, I can come to the inputs.

[00:05:54.280]So this is looking at the data that is creating this vein,

[00:05:57.910]and you can see now that out of the data

[00:05:59.700]that’s making up the hanging wall and the foot wall,

[00:06:02.760]I can choose what I want to snap to.

[00:06:05.740]In this case, I want to snap to my points

[00:06:09.650]and I already have snap to drill holes

[00:06:12.240]selected here as well.

[00:06:18.140]Now that will reprocess again and when it updates,

[00:06:20.880]what you’ll see is that the triangulations here

[00:06:23.589]will now snap to my data as well.

[00:06:35.630]So there you can see the updates.

[00:06:40.010]Now the last thing I want to do

[00:06:41.240]just to make sure that this has worked properly

[00:06:44.780]is we’re going to take a slice at the elevation here,

[00:06:51.489]split this a bit and we’ll look down.

[00:06:57.490]So here you can now see the outline of my vein

[00:07:00.330]based off my mapping data.

[00:07:05.390]We’ll also set the drill holes.

[00:07:10.140]There we go.

[00:07:12.060]Now, if we go back to the copy I took originally

[00:07:14.370]and we load that on, you can see how that has changed

[00:07:18.070]from the original interpretation

[00:07:19.970]to the updated based on the mapping data.

[00:07:24.370]So the great thing is now that you have this setup

[00:07:26.700]is this is now a dynamic edit.

[00:07:30.360]So as you collect more data,

[00:07:32.980]you can refresh your mapping point subject,

[00:07:36.590]which will refresh the context selection

[00:07:39.690]and therefore update your vein.

[00:07:41.820]So just to show you that in action,

[00:07:43.670]if we come back to our full model,

[00:07:47.950]I now have a new set of mapping data

[00:07:50.870]taken here at my 2,970 elevation.

[00:07:55.050]So I’m going to take that data

[00:07:57.500]and I’m going to copy it to the bottom of my current data set.

[00:08:07.610]Click save, and then in my project,

[00:08:12.760]I’m going to come back to my mapping file

[00:08:16.680]and I’m going to choose to reload data.

[00:08:21.730]I’m going to reload the original object

[00:08:29.370]and what we should see is that once that data comes in,

[00:08:32.840]it will update my selection and now you can see,

[00:08:35.130]let’s make this a bit more transparent.

[00:08:38.660]You can see, I have now a new set of data

[00:08:41.930]on my elevation down here.

[00:08:44.600]And as I got a new set of elevation data is now updated.

[00:08:50.960]You can see the vein has now snapped

[00:08:52.780]to this new information.

[00:08:56.090]So it’s really as simple as that.

[00:08:58.100]You create your import file in your points folder,

[00:09:01.140]and you just constantly refresh that

[00:09:03.210]with your new mapping data.

[00:09:05.190]And as you add that data in,

[00:09:06.720]it will work with your project to update your vein.

[00:09:13.600]So thanks very much for joining this quick tutorial.

[00:09:16.610]I’d say there’s plenty more information and guides

[00:09:18.760]and hows to’s on your MySeequent page

[00:09:22.160]and on our YouTube homepage.

[00:09:25.830]Thanks very much.
