Hello everyone
I am writing to get your help to find out how to import a true ground relief.
I want to be able to make a replica of Machu Picchu which is located in Peru.
I would like to know the procedures to be followed for such an achievement.
Can you help me because I want to give the result of this work has two courageous young women I know who have decided to go to Machu Picchu to help a sick child.
I have attached the link to my Youtube channel, which will give you an overview of their humanitarian project.

I also know the procedures to follow to add images or pictures in my work so this is possible.
Thank you in advance
Hoping all compliant.

Search DEM (digital elevation map) and BigBen...he's the master here

You can get free height data ("ground relief") for almost any place on Earth. The USGS Earth Explorer is one way:
http://earthexplorer.usgs.gov/
Terragen can read most of the formats there.
As Bobby mentions, there is lots of existing discussion about it here which provides more details, alternative download sites, etc.

SRTM may be the highest resolution for that area.  SRTM Tile Grabber (http://dwtkns.com/srtm/) is the best site I've found for getting individual tiles.  At 90m resolution though the slopes won't be as steep and you'll need to do some "enhancing"

Thank you all for giving me the answer.
I would like to know if there exist video tutorials to understand the manipulations and techniques that I have to use it because it is easier to learn by viewing the proceedings because I am not very good in English.
Thank's

There is also some scanned data available.

Catching up on my data sources..... 
http://gdex.cr.usgs.gov/gdex/ NASA SRTM 1arcsec is at least an improvement over SRTM2, but coverage is not global

The interface is a bit of a pain in that you have to select an area to download, but at least you can get it

The satellite imagery shows some of the limitations of the terrain.  Dark, bluish-grey patches are cliffs in shadow.  Here's a 360° pano.  I've sent you the files.
