Outcrop Mapper Tool

Note: To enable the Outcrop Mapper tool on Discover Mobile, you need to create an outcrop mapper project on the desktop and associate it with a mobile project. See Outcrop Mapper in Discover for ArcGIS Pro.

If there is an outcrop mapper project associated with the mobile project, you will see a layer named outcrop_location and new Rays icon .

The outcrop map layer saves the point location where the photo of the outcrop was taken.

When activated the ray icon displays a set of rays. The outermost rays represents the Field of View (FOV). The middle line represents the distance and bearing from the point to the middle of the photo. The final line that is perpendicular to the middle line represents the edge of the photo.

Outcrop Map Styles and Thematics

The outcrop layer can be modified like any point layer, see Point Data. Themes can aslo be applied to outcrop map layers, see Thematic Mapping.

Set the Scale Method for an Outcrop Map

There are two methods to set a scale for an outcrop, you can set the scale by a reference object or distance.

1. The Crosshair method used cross-hair in the middle of the interface. On you device, you tap at the start and end of the object to create two point.

2. The Manual method uses a line where you position the nodes at the start and end of the reference object.

Note: When setting the scale with a reference object method, you can toggle between cross-hair or manual method. See Configure Project Settings.

To take an outcrop photo:

1. Select the layer and make it visible by tapping the eye icon.
2. Make the layer editable by tapping the pencil icon.
3. Tap the expand icon.
4. Tap the GPS point button to capture a point at your current location.
5. Enter the outcrop Name.

6. Take a Photo of the outcrop or select a photo from your phone's Gallery.

   The magnetic bearing and the inclination data are displayed.

7. Select the Scaling Method from Reference Object (Pick/Hammer) and Distance (Laser Pointer/Tape).

   If the Scaling Method is Reference Object (Pick/Hammer) select whether you are using the Crosshair or Manual method to measure the reference object.

8. Tap Save.
9. Complete the following fields as required.

   • Outcrop Type—Select from Section and Drape.

     Note: If Section, is selected planar photos are created in the desktop software. If Drape, is selected, the photo is draped on a surface grid on the desktop software.

   • Unit—The unit of measurement for the reference object.
   • Measurement—The length of the reference object.
   • Distance—The distance from the capture point to the centre of the outcrop photo.
   • Height—The height of the device/camera to the ground surface.

   • Pitch—The angle the device is held from the horizontal plane.

     Note: Negative pitch points down and positive pitch points up from the horizontal plane.

   • Bearing—The angle of magnetic north on the device to the outcrop photo.

10. Tap Save.

    The data entry window displays the outcrop layer with your outcrop image.

11. Tap Save.

    You are prompted to Edit Outcrop Photo now or later.

12. If Yes, edit now is selected, you can add points, lines and polygons to the outcrop image. See Point Data, Line Data, Polygon Data.

Measurements of an Outcrop Image

To take measurements of features in the outcrop image, see Measure Distance.

View outcrop image properties:

1. In the layer control menu, tap the object info icon.

   The outcrop image properties displays as seen in the image below:
