RGB and Multispectral orthomosaics obtained by processing raw imagery (dated 20240528) in webODM software

This dataset encompasses the following data: RGB and Multispectral othomosaics of 6 vineyards located in Alentejo. DJI Mavic 3M RTK drone was used for the data collection while webODM was the software used for the processing of the raw imagery. 
 

Further details:

1. RGB and multispectral imagery were processed separately in webODM using two different sets of parameters

2. RGB parameters: auto-boundary: true; dem resolution: 1.4; dsm: true; orthophoto resolution:1.4; pc-quality:ultra.

3. Multispectral parameters: auto-boundary: true; optimised disk space: true; pc-quality:ultra; rediometric calibration: camera+sun; skip band alignment: true.

4. The orthomosaics corresponds to the following time points: 2024-05-28, 2024-06-24, 2024-07-22, 2024-08-06, 2024-08-23, 2024-09-04

Important notes: 
1. prior the processing of the multispectral imagery in webODM a script for aligning the 4 bands had to be run ( issue: https://community.opendronemap.org/t/misalignment-between-bands-in-mavic-3m-multispectral-images/15996 solution: https://community.opendronemap.org/t/pre-processing-script-for-multispectral-images-from-the-dji-mavic-3m/20743) 
2. all the multispectral othomosaics show extremely low values of reflectance data after the radiometric calibration (https://community.opendronemap.org/t/radiometric-calibration-seems-wrong-for-the-dji-mavic-3m/22693 ). A solution to this potential issue has not been found yet.

Possible applications: the dataset can be used by anyone interested in seeing changes in productivity due to abiotic and biotic stresses. In this case, the main biotic stress acting in the vineyard is represented by the green leafhopper, Jacobiasca lybica.
