Visualizing raster data

Once you have raster data uploaded to the drive you can start to create visualizations. Ellipsis Drive offers you the ability to make and apply visualizations on the fly in the ‘Visualizations‘ tab in Map Settings. The Drive will suggest a default visualization based on the data that you uploaded (such as a simple rgb image), but you are welcome to customize this or add extras. To do this you can click ‘New Visualization’ at the top right of the screen, or by clicking the ‘edit’ icon.


When creating a new visualization you can choose a method from the dropdown at the top of the screen. Here you can chose between:

RGB; to visualize spectral data
Index; to visualize different indices with (multi) spectral data
Color scale; to color code i.e. classification or measurement rasters
Color fade; to color code i.e. classification or measurement rasters with faded borders between values
– Contour; to visualize elevation data in 2D
Hill shade; to visualize elevation data in 2D
– Vector; to visualize forces such as wind speed and direction

When you have a fitting method selected you can specify your visualizations based on the values in your raster in ‘method options’. The map at the bottom of your screen shows a preview of what your visualization will look like based on your present settings. When you are satisfied, you can click ‘save visualizing’ at the top right of the screen. When adding a new visualization, don’t forget to give it a name! The new visualization will become visible/available after the drive has processed your request. So sit back, relax and enjoy the flight.

 

Tip: when uploading i.e. classification, altitude, or measurement raster, it is best to upload them raw, rather then creating a visualization before uploading. When uploading them raw, the visualization remains flexible. Meaning that you can add multiple and also change them on the fly.
