Yes. Each sensor can have a unique filter installed.
The Quanta has customizable filter sets for a wide range of applications including measuring vine vigour, water content, and detecting disease.
We provide the filter sets to meet your requirements and our talented team of experts will be happy to help you select the specific bands.
The Quanta is not intended for ground based vehicles, but it can be modified to work with various aerial platforms. To discuss your requirements, please contact us.
DroneFuse is compatible with Android, iOS, macOS, Windows, and will soon be compatible with any web browser.
The desktop version keeps itself up to date and notifies you when it needs to restart. Updates to the mobile version are made through the App Store on your mobile device.
Yes, DroneFuse has mobile capabilities, allowing you to take your data with you anytime, anywhere.
When your survey has successfully uploaded, processing begins immediately through DroneFuse. Your images go through an initial quality check, and then are aligned and calibrated to reflectance. These calibrated images are then stitched into an orthomosaic, which is used to conduct further analysis and create final data products.
For the EVI Standard and EVI Analytics packages, your final data products will be accessible after 48 hours of processing time. For disease detection and custom requests, processing time could take slightly longer.
Depending on your package, the data can be used in different ways. The PDF maps can be used as standalone references to view and assess your parcels. The PDF maps are also completely georeferenced, and can therefore be loaded into Google Earth or GIS software for overlaying on other satellite images. If you opted to purchase the Enterprise GIS Data, you will be able to use these files in your own GIS analysis workflow. All files are georeferenced to the local UTM zone (WGS84 datum), unless otherwise requested. For more information on how our specialized data solutions can optimize your vineyard performance, check out our website.
Yes, if you choose to purchase the Enterprise GIS Data. This will give you access to all raw final products used to create the final map results.
You can view your data and results on DroneFuse, our mobile data viewer, as well as PDF maps. We currently offer two options for viewing final results: PDF maps, and a Mobile Data Viewer. The PDF maps are completely georeferenced, and can be loaded into the software of your choice.

Although our primary focus is on vineyards, our technology has applications for other crops such as avocados, apples, peaches, cherries, apricots, etc. We are always conducting new research and looking to expand our service offering.
The best flight parameters are mission specific. For flights measuring Calibrated Vine Vigour, you can fly higher and faster whereas disease mapping, which requires higher resolution, you will want to fly slower. Set speeds to 5m/s at 50m, 6m/s at 60m , 7m/s at 70m and 8m/s for 80m or higher. If you have any questions please contact us and a member of our support team will be happy to assist you in determining the best flight parameters for your mission.
Although the Normalized Difference Vegetation Index (NDVI) is generally considered the standard used to measure wine vigour in the wine industry, it often provides inaccurate results due to its dependency on time of day, soil variations and shadowing. Enhanced Vegetation Index (EVI) is calculated similarly to NDVI but uses additional wavelengths of light to correct for these inaccuracies and variations in solar incidence angle, atmospheric conditions, and canopy background signals, providing the most accurate vine health information available.
Lighting conditions can vary depending on many factors including sun angle, time of day, and sky conditions. In order to account for these factors, it is necessary to normalize all imagery to a known reflectance standard. Our calibration ensures consistent results when comparing imaged scenes to one another, regardless of the flight time or conditions. It also allows us to obtain consistent results with respect to disease mapping, and allows us to derive an absolute EVI scale which can be used field-to-field to define vigour.
The difference between the relative and absolute scales is the way the color is applied to the raw data layers. The relative colors stretch from the minimum value within the data to the maximum value, to highlight intra-field variability. These values are recorded on the legend so that you know the range that is being shown- sometimes it will vary greatly (~ 0.30 difference), and other times it will be very close (~ 0.05 difference). What you see as green on these maps is not comparable with what you would see as green on other Relative EVI maps from different fields or dates.
The Absolute colors are established across the entire possible range for the EVI (0-1) so that you can compare those colors with the colors from other fields and other dates (inter-field variability).
