Understanding Satellite Imagery

We can remotely map some area in OpenStreetMap using satellite imagery. Unfortunately, for those who don’t really understand about satellite imagery, they usually get confused and can’t recognize what kind of objects are in the satellite imagery. This Tracing Guideline using Satellite Imagery made to help you understand in recognizing and identifying any objects in satellite imagery.
