The Line tool allows you to measure the length and slope of a structure from an oblique photo. Use the Area Tool if you want to measure other parts of the structure.


This guide includes the following sections:


Accessing the Line Tool

  1. To access the Line tool for obliques go to the location you want, then switch to oblique view, either by clicking the View Oblique Photos in the location information, or by using the compass tool:



  2. Once you are in oblique view, click the Line tool:



Measuring Lines

  1. Zoom into the structure you want to measure, then draw a line along the slope you want to measure:



  2. Click Next, and you will see the vertical view of that structure. Drag each endpoint of the line to the slope you are measuring:

You will now be able to see the slope in degrees, as well as the line length.

You might find it helpful to click between the primary view and the secondary view when you are measuring the lines.


Once you are done, you can change to any view, and the line will still be there. In this example, the view is now oblique with South-East orientation:


Tips for Measuring Lines

  • Zoom in as much as possible and take your time for best results.
  • Always draw along the edge of the structure you want to measure.
  • Switch back to the primary view to check line placement and orientation if you are not sure.
  • You can also choose another photo from a different direction from the drop-down list.
  • Ensure you are zoomed in enough when drawing the line. Drawing the line when not zoomed in may result in a less accurate measurement.
    In the example below, when zoomed out too far the slope is 4.8 degrees:



When zoomed in the pitch is 1.2 degrees:


Note: Viewing Oblique photos and measuring lines are available only in the New MapBrowser.

Exporting Image with Lines

You can use the Export Tool to export a screenshot, which will include the line measurements and the survey date:


Note: The survey date in the screenshot may differ from the actual capture date of the image, as explained in Survey Date and Photo Time.
