The Elevation Toolbox is a set of tools paired with a digital surface model used for measuring and understanding the elevations information of the models you create 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?
If your data was processed while on the Explorer (Free) plan and does not have the Elevation Toolbox, it will need to be re-uploaded and processed to generate the elevation layers.
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.
When you open your map from the dashboard, it will automatically be brought to the 2D map. Choose
Elevation from the options 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.
There are several adjustable fields on the Elevation map: Range of values, color and intensity.
Editable options on the Elevation toolbox.
You can select a different coloring by clicking the Color Dropdown. You have two option, Jet and Gray:
Viewing the elevation data in grayscale instead of the Jet color scheme.
You can also select different intensities of the shadows, from Low to Max, to emphasize depth:
Jet coloring with medium Intensity.
Jet coloring with no Intensity.
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.
Adjust the range of the elevation presented using the handles at the bottom of the histogram.
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.
The number at the top of the histogram presents the are of the map that falls within the range specified by handles 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
Steps to display the elevation profile: 1. Create a line using the distance tool. 2. Click on the line so you see the cross arrows. 3.View the elevation profile in the map panel at the left.
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.
Export, select the
Elevation Layer an choose the right file format that you want to export.
Learn more about the different file formats available for export in our guide Data Export Formats.
