The Elevation Toolbox is a set of tools paired with a digital surface model used for measuring and understanding the elevation in 2D. These tools allow you to explore your data even more deeply through a perspective of the elevation and depth of each area of the map.
The elevation data on your map is taken from the embedded geotags on your images. The Elevation Toolbox is automatically generated when you upload your imagery to DroneDeploy.com.
How can I access it?
By using the Elevation Toolbox, you can adjust the contrast to highlight variability within your map.
What is the elevation relative to?
Your elevation map is relative to the takeoff point of the drone. This means a negative area on your map is lower than your takeoff point.
To get started, select
Elevation from the side panel at the left.
This will update the panel in the top left showing a histogram of the elevations of the data, and the data itself. Clicking on the histogram to the left brings up a new option.
By Clicking on Advanced Elevation, you can access several adjustable fields on the Elevation map: Range of values, color and intensity.
You can select a different coloring by clicking the Color Dropdown. You have two option, Jet and Gray:
You can also select different intensities of the shadows, from Low to Max, to emphasize depth:
The elevation histogram has a few different values. Using the bottom sliding bar, you can change the values presented on the map. The map will automatically update.
The top row of numbers is the area of the total map that falls within the range specified using the scale bar at the bottom.
Using the Distance tool within the Annotation & Measurement Toolbox, you can display the cross-section or elevation profile of your map.
The elevation profile is useful to:
- Measure the height of certain features
- Measure the slope of the line segment (height change / distance)
- See if an area is flat/bumpy/sloped
After making sure you have the appropriate limits set in the histogram, you can export the elevation data by selecting the
Elevation Layer within the Export tool.
You will see several formats to choose from, including Contours and Raw Elevation Values (DEM), if you are in the Business or Enterprise subscriptions.
Learn more about the different file formats available for export in our guide Data Export Formats.
