Once you have delineated your selected investigations you can create a cross section.
To add the cross section module navigate to your project page and under the Data Interpretation Section click 'Add Interpret Module'
From here select the 'Cross Section Generator' and give the module a name.
Once you have added the module you can draw cross section lines on the map using the drawing tools.
There are 5 icon on the the drawing tool from left to right these are a
- A tool tip to tell you have to finish a drawing
- A draw tool
- An edit too
- A save button
- A delete button
At the top of the map there are instructions on how to use the tools
Once you have drawn your cross section, you will navigate to a screen where you can see a panel with different tabs.
- Select Delineation: This is where you can configure your cross section, like give is a name, select your elevation model and select the investigations you would like to show on your cross seciton
- Interpolate: Here is where you draw your ground profiles
- Review & Export: Here is where you can export your cross section
The first step is to configure your cross section by naming the cross section, you can give your cross section a long name which will be shown in the exports and a short name which will be shown on the map, and selecting the elevation model.
The elevation data can be either data that we have already added to the Apeiron Platform or very soon it can be elevation data that you will be able to add to your project.
Once you have configured the section you can add the investigations you want to see on the cross section. We leave the choice of what investigations you want to show up to you to step up to as depending on the area investigations may or may not be appropriate to add investigations to the cross section.
There are two ways to add investigations so they show on the cross section. the first way is to click on each investigation on the map. Then they are selected they will show on the side panel as being selected and the labels on the map will teal when they have been added to the section. The other is to set a capture distance, the capture distance will automatically select all investigations within that distance of your drawn line. While the capture distance automatically selects all investigation.
At any point if you decided you don't want an investigation on your section you can remove these investigations by either clicking the selected investigation on the map again or by removing them from the list on the side bar.
Once you have selected all the investigations you can move to the interpolate tab to start defining the geological cross section. The main feature of this tab are shown in the photo below:
- The layer library, this is pulled through from your delineation, if you want to change these, you can go to you delineation module and add to the layer library there.
- The warning section, while drawing your layers if there are any errors warnings will show here
- The drawing tool bar, here you can choose the layer you are drawing, edit the later and draw a groundwater line
- Instructions of how to use the drawing tool
- The cross section canvas
- If you have drawn multiple cross sections the intersection point will be shown on your cross section
The delineated sticks and ground profile will be added automatically based on the selections on the 'Select Delineation' tab. Currently we don't auto suggest anything else as we have left it to the user to interpret where the soil profiles go. The delineated sticks are always in sync with your delineation module, when updates are made to you delineations the stick in the cross section will update as well.
To draw the layers on the cross section click the pencil icon (1) and then click on the cross section canvas to add points to draw a layer (2)
To edit the layers on the cross section select the edit icon (1) and select the layer you to edit (2) the points you previously draw have highlighted with with red dots (shown in 3a). You can either click and drag the points you have already drawn (3a) or you can add new points by placing your curser along the line and when the grey icon (shown in 3b) appears you can click and drag to add a new point.
You can delete the layer by clicking the red delete icon next to the edit icon. This delete icon will only appear after you have selected edit.
To add a groundwater line click the water drop icon (1) and click on the map to draw the line (2). To edit your groundwater line follow the same steps, you will redraw a groundwater line which replaces the previously drawn line.
Once you are finished and happy with the cross section you can export the cross section you have created. You can move to the 'Review & Export' tab We have two export methods dxf which is a digital export that you can import into a CAD software or a modelling software like Geostudio or Rocscience. We also have a PDF export that will be released in the near future.
To export the DXF file, click generate and when the export has been generated you can download the DXF file. The PDF export will follow the same methodology.
The cross section in the example above has investigations that didn't always line up with the ground line. In some cases this may be expected due to the offset distance, but where this may not be the case its really easy to update in our system.
In the example above you cam see that BH-6RRL-LE4Ns elevation is near 0. This could been because its an in progress investigation, or it could been cause the metadata was wrong from ingesting of the investigation. Either way we can go to data select, update the elevation and when we go back to the cross section we can see that the investigation has moved to a more appropriate elevation.
Once we are in data select we can either use the drop down of Selected investigation or the map pop up to navigate to our investigation of interest. Under the 'Adjust Elevation' section we can see how the investigations elevation is currently applied, in this case its from the investigations metadata and is showing an elevation of 3m RL. We change the elevation either manually assigning and elevation, or we can peg the elevation to an elevation model.
In this case I will peg the elevation to a model, the same model we have used in our cross section. The elevation is now 24.36m RL
When we go back to our cross section we can see that our investigation has become inline with our cross section. The top photo is the original the bottom photo is where the investigations metadata has been updated.
