Visualization Guidance
After opening the raster file in QGIS (or other Geographic Information System), the layer symbology defaults to black for values of zero and white for values of one (as seen in the image below).
By setting 0 as an additional no data value, it is possible to view the Built Up Surface layer atop satellite imagery
-
First, open the Layer Properties window by double clicking on the layer in the Layers panel
-
Second, open the Transparency tab (1), set "Additional no data value" to 0 (2), and click "OK" (3)
After clicking "OK" the layer symbology changes to black for values of one and transparent for values of zero, allowing a satellite image layer to appear beneath (as seen in the image below).
