In three quick steps:
- log in
- upload your image
- select the visualization method to scan your image
Example: Australian bush fire smoke and haze – original Sentinel 2 image – size: 530 kb, file type: jpg
ORIGINAL UPLOADED: with spectrograph and entropy value
With DroneVee Reflectance Level 1 scan (materials reflectance intensity mainly with reflected light waves, by spectroscopy and materials variability entropy):
With DroneVee Reflectance Level 2 scan (materials reflectance intensity mainly with reflected light waves, by spectroscopy and materials variability entropy):
With DroneVee Refraction scan (materials refraction intensity mainly with refracted light waves, by spectroscopy and materials variability entropy):
With DroneVee Absorbance Level 1 scan (materials absorbance intensity mainly with absorbed light waves, by spectroscopy and materials variability entropy):
Absorbance Level 2 method is also available. .
You can also:
- select the auto spectrograph to plot and view how materials in your image interact with light (reflection, absorption etc.). You will also see a value (entropy) telling you the variability of the materials or objects in your image.
- select ‘Save’ to save your image in your device.
- use the ‘screenshot in your device or browser to capture the image with the spectrograph or by itself.
NOTE: Files types Tiff, GeoTiff, Jpg, PNG and BMP can be processed. On average, each result takes less than 15 seconds depending on your file size and Internet speed. The larger your file size, the more time it takes to deliver each result so be aware! Keep file sizes small but with optimum resolution. Ideally, your file size should be less than 1Mb. Also, compared to the beta version of the DroneVee engine, the released version of the DroneVee engine will deliver greater penetration images and faster.
What is a surface?
By our definition it is any material that prevents or reduces visibility beyond it. Smoke, haze, soil, leaf ‘skin’ and planetary dust are all examples of surfaces. Subsurface is what is visible beyond it.
What is a spectrograph?
The spectrograph plots the level of reflectance at various wavelengths for the material within the image. It can be used in many ways to gain insight of the materials captured in the image.
What is ‘entropy value’?
The entropy value indicates the average variability of the materials encountered in the captured image. This helps to provide insight into the smoothness of the material encountered for example.
