“NDVI Remote Sensing: Matrice 100 AgroSENSE” Technology
NDVI: the importance
The demand for immediate action in the agriculture industry where timing is vital has become an essential need. Precision Farming has so far reasonably focused on the detail and the accuracy of the attainable results. In consideration of the fact that cultivations growth stages change at a very high speed and that factual, timely information is required in order to be able to promptly make the corrective decisions Analist Group has devised a revolutionary system: AgroSENSE.
AgroSENSE: timely and immediate NDVI
The main features of the AgroSENSE technoloy are:
- timely and immediate results
- processing simplicity and speed
- intuitive, simple workflow
How is the AgroSENSE approach different from other multispectral remote sensing imaging processing tools?
The AgroSENSE objective is not the creation of a detailed orthomosaic.This feature is sublimely one if not the most important difference. In order to achieve immediate factual information the AgroSENSE technology allows for a much faster workflow. With the new technology no massive quantity of frames is required, no overlapping thus no lengthy processing times. One simple photo processed by AgroSENSE in Analist 2016 CLOUD provides the NDVI index for a first immediate evaluation of the surveyed area. With the AgroSENSE Matrice 100 Solution with the modified Sony QX1 Camera we have the possibility to approach multispectral imaging with two frames of mind. The camera is of the most elevated quality and with its 8MP (3550×2250) per colour channel for 20.1 MP cameras allows for traditional photogrammetric approaches with cm accuracy as well as for more higher elevation flights with fewer frames, thus extant detailed results. This to say that with AgroSENSE the user can promptly access vital information on macro-areas for first impact timely evaluations.
