资源简介:
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.
本数据集包含以下内容:位于葡萄牙阿连特茹(Alentejo)地区的6处葡萄园的RGB影像与多光谱(Multispectral)正射影像镶嵌图(Orthomosaic)。数据采集使用大疆御3M RTK(DJI Mavic 3M RTK)无人机,原始影像的后期处理采用webODM软件。
### 详细说明:
1. RGB影像与多光谱影像分别通过两套不同参数在webODM中独立完成处理。
2. RGB影像处理参数:自动边界(auto-boundary):启用;数字高程模型(DEM)分辨率:1.4;数字表面模型(DSM):启用;正射影像分辨率:1.4;点云质量(pc-quality):超高。
3. 多光谱影像处理参数:自动边界(auto-boundary):启用;优化磁盘空间:启用;点云质量(pc-quality):超高;辐射定标(radiometric calibration):相机+太阳;跳过波段配准(skip band alignment):启用。
4. 本次采集的正射影像镶嵌图对应时间节点为:2024-05-28、2024-06-24、2024-07-22、2024-08-06、2024-08-23、2024-09-04。
### 重要注意事项:
1. 在webODM中处理多光谱影像前,需先运行用于配准4个波段的预处理脚本(相关问题讨论链接:https://community.opendronemap.org/t/misalignment-between-bands-in-mavic-3m-multispectral-images/15996,解决方案链接:https://community.opendronemap.org/t/pre-processing-script-for-multispectral-images-from-the-dji-mavic-3m/20743)。
2. 所有多光谱正射影像镶嵌图在辐射定标后均呈现极低的反射率数值(相关讨论链接:https://community.opendronemap.org/t/radiometric-calibration-seems-wrong-for-the-dji-mavic-3m/22693),目前尚未找到该潜在问题的有效解决方案。
