QGIS + Mapflow : Extract Building Footprints

How to extract building footprints from satellite imagery?
Building footprints are often used for base map preparation, humanitarian aid, disaster management, and transportation planning
There are several ways of generating building footprints. These include manual digitization by using tools to draw the outline of each building.
Let's see how we can do this in QGIS...

I cannot save as shapefile. Save as option is not active

Great Video, very informative. Do you know how I would be able to count the number of buildings in specific area?

[@EasyyLearn]

Thank you! We usually count the number of elements with SGIS, using the smart polygon selection and then exporting selected elements in new layer. In the info tab, the number of *polygons (parcels, buildings), lines (routes), or points, are automatically displayed 🙂

Do you have to pay for this tool?

[@EasyyLearn]

Their website provides all the information regarding the availability of free and paid features.
