Hello everyone.
I am working on a project where we want to quantify the area of bare soil or with little vegetation cover in meadows and pastures used in livestock farming. This as a basis to later be able to compare with the past if it improved or worsened. It is also the idea of improving forage production in these areas and avoiding further degradation. These bare areas are still unclear as to what caused them.
The area that I am going to monitor is approximately 500,000 hectares. Located in country: Paraguay around the city of Filadelfia (https://maps.app.goo.gl/dhX3zR2wFbdo57o18).
My question is what would be the best way to do it?
I attach a Google Earth image of what we are looking to measure.
What did I already try:
1) Perform automatic classifications with sentinel images of the various areas.
2) With sentinel images (10x10 meters) calculate the "modified Soil Adjusted Vegetation Index" (MSAVI) but as expected the resolution area is very large.
What do you think of this? What other options do you suggest?
Some cons are:
There aren't many satellite sensors to choose from.
