  "description": "<p>This land cover map of Dakar (Senegal) was created from a Pl&eacute;iades very-high resolution imagery with a spatial resolution of 0.5 meter. The methodology followed a open-source semi-automated framework [1] that rely on <a href=\"https://grass.osgeo.org/\">GRASS GIS</a>&nbsp;using a local unsupervised optimization approach for the segmentation part [2-3].</p>\n\n<p>Description of the files:</p>\n\n<ul>\n\t<li>&quot;Landcover.zip&quot; :&nbsp;The direct output from the supervised classification using the Random Forest classifier.</li>\n\t<li>&quot;Landcover_Postclassif_Level8_Splitbuildings.zip&quot; : Post-processed version of the previous map (&quot;Landcover&quot;), with reduced misclassifications from the original classification (rule-based used to reclassify&nbsp;the errors, with a focus on built-up classes).</li>\n\t<li>&quot;Landcover_Postclassif_Level8_modalfilter3.zip&quot; : Smoothed version of the previous product (modal filter with window 3x3 applied on the &quot;Landcover_Postclassif_Level8_Splitbuildings&quot;).&nbsp;</li>\n\t<li>&quot;Landcover_Postclassif_Level9_Shadowsback.zip&quot; : Corresponds to the &quot;level8_Splitbuildings&quot; with shadows coming&nbsp;from the original classification.</li>\n\t<li>&quot;Dakar_legend_colors.txt&quot; : Text file providing the&nbsp;correspondance between the value of the pixels and the legend labels and a proposition of color to be used.</li>\n</ul>\n\n<p>&nbsp;</p>\n\n<p>References:</p>\n\n<p>[1]&nbsp;Grippa, Ta&iuml;s, Moritz Lennert, Benjamin Beaumont, Sabine Vanhuysse, Nathalie Stephenne, and El&eacute;onore Wolff. 2017. &ldquo;An Open-Source Semi-Automated Processing Chain for Urban Object-Based Classification.&rdquo; <em>Remote Sensing</em> 9 (4): 358. <a href=\"https://doi.org/10.3390/rs9040358\">https://doi.org/10.3390/rs9040358</a>.</p>\n\n<p>[2]&nbsp;Grippa, Tais, Stefanos Georganos, Sabine G.
