I’m new on this forum. I don’t speak very well english but i’ll try.
I’m studying geography in Nantes and currently i’m in internship in a regional natural park in the Pyrenees.
I have some Spot images from the Infrastructure of Spatial Data Theia (World Spot Heritage) which are distributed only in TOA reflectance. I would like to convert this image into TOC reflectance using “Optical calibration” from the OTB.
In this tool there is the choice between three options :
- Image to TOA
- TOA to image
- Image to TOC
And I want to modify my image from TOA reflectance to TOC reflectance.
Which option should I use ?
(I have already read the cookbook and the user manuel)
OTB 6.6.1 / QGIS 3.4 / Win 10
