Integrated Topographic Corrections Improve Forest Mapping Using Landsat Imagery
--
doi.org/10.1016/j.jag.2022.102 <-- shared 2022 paper
--
“HIGHLIGHTS:
• [They] evaluated the impacts of topographic correction on forest mapping in the mountains.
• The enhanced C-correction and the physical model reduced topographic effects.
• The corrected Landsat imagery time series resulted in higher accuracy.
• Terrain information improved classification but not as much as topographic correction.
• [They] recommend using topographic correction for forest cover mapping..."

I have to share my colleague's first #PhD paper. It is a cool one!

Comparison of #greenery across 86 European cities and their active travel environments.

Residential areas are much more green than travel environments in European cities. Seasonality is often overlooked, but crucial for accurate assessments of #urban greenery.

“Vegetation indices are mathematical expressions that help to quantify the health, density, and vigor of vegetation from remote sensing data. They are widely used in various applications such as agriculture, forestry, ecology, and land management. Here are ten common vegetation indices and their applications:..”
