Technical documentation for pilots and photogrammetrists
Just select your camera from database, mention the flight height, length and width of your area and immediately get your flight time, intervalometer frequency, number of shots, GSD and orthophoto final weight.
Drones Imaging processes all your images (with geotag or not) and does not set any requirements regarding the resolution. However, we recommend that you use a camera with a mechanical shutter and a minimum resolution of 20Mpx.
Depending on the complexity of the aerial scenario: agriculture, vertical walls, banks, rivers, historical monuments, topographic surveys etc. Drones Imaging guides and advises you on the optimal capture strategies and conditions.
Useful document illustrating the image level of detail according to the shooting height (from 40m to 800m) and/or its resolution (from 1cm to 20cm GSD).
The normalized difference vegetation index, also called NDVI, is built from the red (R) and near infrared (NIR) channels. It highlights the difference between the visible bands of red and near infrared: NDVI=(PIR-R)/PIR+R).
This index is sensitive to biomass and health vegetation.
Bright index is built from red (R) and near infrared (PIR) channels following a calculation IB = √(RxR+PIRxPIR).
The bright index represents the average of the image brightnesses. This index is therefore sensitive to the shine of the soil, linked to its humidity and the presence of salts on the surface. It mainly characterizes the albedo.
Drones Imaging offers you professional know-how and continuous access to cutting-edge technology.
From your client to post-processing, an aerial planning mission can be difficult to prepare. If you need help with flight planning, acquisition strategy, target setting, geo-tagging, post-processing or setting up your sensor: contact us, we will advise for you deliver very high quality of deliverables.
All our work is build from the original images with optimal resolution. If you find that quality is not enough, we will make the necessary corrections.
