To plot SHmax directions (borehole breakout) on ArcGIS, you can follow the following steps:
Collect borehole breakout data: Collect borehole breakout data from the field or obtain it from a reliable source.
Create a point shapefile: In ArcGIS, create a point shapefile where you can input the coordinates of the borehole location.
Add the borehole data: Add the borehole data to the attribute table of the point shapefile. The borehole data should include the location of the borehole, depth of the breakout and the SHmax direction.
Symbolize the SHmax direction: Go to the Layer Properties of the point shapefile and symbolize the SHmax direction using arrows. You can use the "Arrows" symbol from the "Symbol Selector" to represent the SHmax direction.
Set the properties of the arrows: Set the properties of the arrows, including the size, color, and rotation angle. The rotation angle of the arrow should correspond to the SHmax direction value in the attribute table.
Label the boreholes: Label the boreholes using the "Label" option in the Layer Properties. You can label the boreholes with the borehole name, depth of the breakout, and SHmax direction.
Save the map: Once you are satisfied with the map, save it as a project file or export it as an image file for further use.
