Use the Area Tool with Obliques when you want the dimensions of the face of a structure. This tool will provide area, perimeter and slope from an oblique photo.


This guide includes the following sections:

Accessing the Area Tool

  1. To access the area tool 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 Area tool:


Measuring Areas

  1. Zoom in on the structure you want to measure, then draw around the face you want to measure. Always measure a single face that has a single slope.




  2. Click Next, and you will see the vertical view of that structure. Drag the vertices to match the corners of the area you are measuring:


You will now be able to see the area and perimeter, and the slope in degrees.

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


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

Tips for Measuring Areas

    • Zoom in as much as possible and take your time for best results
    • For complex structures, measure each section of the structure separately, preferably as a three or four-sided polygon. Do not measure an entire structure as a many-sided polygon.
    • Where the structure has several different slopes, measure each sloped section separately.
    • Switch back to the Primary view to check line placement and orientation if you are not sure.
    • From the Photos dropdown list, you can choose another photo taken from a different direction.
    • Ensure you are zoomed in enough when drawing the area. Drawing the area when not zoomed in may result in a less accurate measurement. You can see an example in Tips for Measuring Lines.


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

Exporting Image with Areas

You can use the Export Tool to export a screenshot, which will include the area 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.
