What do you need to draw a map?
[ Select answer ]
Be a good painter to capture what we see exactly
Know in detail the relief of the place to draw our landscape well
Have many photos of the terrain to make a collage with all of them
Data of distances and altitudes of the terrain with respect to reference points

What is the difference between a flat or 2D map and a figure in space or 3D?
On a map we cannot represent mountains but we can represent rivers or roads
In a 2D map we cannot see the depth of an object, as it is seen in a 3D map
A figure in space has different perspectives that we cannot capture on a 2D map
In a 2D map we only have surfaces, in a 3D map we have volumes
