This is a very-high-resolution land cover map of Dar es Salaam derived from satellite imagery (Pleiades, 0.5m resolution). The majority of the area is classified from a 2016 (July) image while a small part of it from two images collected in January and March 2018, respectively. The pixel values related to the following legend: 5=tree 8=shadow 3=artificial ground surface 4=low vegetation 2=water 7=bare ground 1=building 113=high elevated buildings 112=medium elevated buildings 111=low elevated buildings The Out of Bag error of the product is 6,38% with the following class errors: Building = 0.035826 Water = 0.049934 Artificial Ground Surface = 0.077108 Low Vegetation = 0.108709 Tall Vegetation = 0.062278 Bare Ground = 0.13803 Shadow = 0.019872 References: [1] Grippa, Taïs, Moritz Lennert, Benjamin Beaumont, Sabine Vanhuysse, Nathalie Stephenne, and Eléonore Wolff. 2017. “An Open-Source Semi-Automated Processing Chain for Urban Object-Based Classification.” Remote Sensing 9 (4): 358. https://doi.org/10.3390/rs9040358.
