“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..."

Ich weiß nicht ob das experimentell genug ist für den #FotoVorschlag heute. Die Bilder habe ich mit einem #raspberrypi mit Touch und der #pinoir Kamera gemacht (darf kein infrared-blocking filter haben). Ich hab ein Skript geschrieben das mein Pi immer das 'custom low effort Digicam Script' bootet und via Touch auslöst. Vor der Kamera war ein Blaufilter. Ist eine low budget Technik um die Pflanzengesundheit zu checken (#NDVI). Irgendwann will ich das nochmal machen

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.

Klein, et al. (2024) Temporal variation in travel greenery across 86 cities in Europe.
