What many viewers might not immediately realize about Pixar’s upcoming film “The Good Dinosaur” is that the studio recreated over 13,000 square miles of actual landscape ranging from Wyoming’s Grand Teton National Park to Yellowstone National Park for the film’s set.

Set Supervisor David Munier and his team built a new software specifically for the film that allowed the usage of U.S. Geological Survey (USGS) data to create the virtual world that the film’s main characters, Arlo and Spot, would traverse.

“We would recreate these massive areas that were 110 by 80 kilometers of the Grand Tetons,” Munier said during a private presentation at Pixar headquarters in Emeryville, Calif. “We ended up using data that covered 13,000 square miles of wilderness.”

Pixar’s newest director Peter Sohn along with Producer Denise Ream and other members of the filmmaking team ventured through these same areas on horseback, only to fall in love with what they saw.

“They were ecstatic when they got back, and they wanted to be able to capture that,” he said.

That desire to bring real natural landscapes to an animated film provided a goal. It was up to him to find a way to get there.

“They asked us, ‘How can we have lots of shots like that without having each one be something really special where we have to hand sculpt mountains?’” Munier recalled.

“More specifically, Peter really pushed us to be able to make a film where we could follow his characters with a camera throughout the environments and see off into the distance at all times,” he said.

Usually the backgrounds of vast outdoor establishing shots in animation are painted in after the virtual camera has been assigned to a fixed spot.

Munier admitted that at first the request was “a huge challenge” but after the system was configured it was a matter of dropping in readily available USGS data into the program.

“So what we did is we looked at the U.S. Geological Survey’s website,” he said. “They have lots and lots of satellite data with photos and height data.”

“We downloaded that and stuck a virtual camera into that data and see something similar we would see in a photograph.”

At this point, Sohn was essentially able to navigate around the landscape for miles and miles to find locations and settings for the movie.

Once a location caught his eye, Munier and his team would get to work by filling in the finer details such as “rocks, grass, trees and other environmental details to give Pete a quick way to start filming.”

With almost all of the film taking place out in the open, Sohn thought that a lot of care and time should be put into designing the setting, which resulted in creating miles and miles of usable landscape.

The motivation behind all this came from Sohn’s desire to treat nature as the primary antagonist to Arlo who gets caught in a raging river during a storm that subsequently leaves him far from home.

“I grew up watching films like Black Stallion or Never Cry Wolf and really loved the cinematography of those films,” Sohn said. “This movie takes place outdoors 99.999 percent of the time and we’re one of the few rare movies to do that. I wanted to recreate that feeling.”

The result is a very real and danger-riddled landscape that may even be familiar to some viewers who know the areas well.

“The Good Dinosaur” will be in U.S. theaters on Nov. 25, 2015.
