CALGARY \u2014 When clinging to the side of a rock wall hundreds of metres in the sky, avoiding a single misstep can save your life.<\/p>\n

Turns out there\u2019s an app to help with that.<\/p>\n

Ben Pearman, a rock climber since age 18, said the idea of the app came to him while his group was trying to determine the best way to climb the south face of Mount Yamnuska in southern Alberta\u2019s Bow Valley.<\/p>\n

\u201cYou get up there and the whole thing looks sort of like a planar surface from far away, like one big sheer cliff,\u201d Pearman said in an interview.<\/p>\n

\u201cThe scale just swallows you. And you\u2019re like, \u2018Oh man, it\u2019s really easy to get lost here.’\u201d<\/p>\n

The sheer limestone wall of this climbing route is known as Red Shirt, and Pearman said it\u2019s the \u201ccrown jewel\u201d of climbing in the Rocky Mountains.<\/p>\n

The 29-year-old is a master\u2019s student in the University of Calgary\u2019s Department of Computer Science. He decided to turn a climbing map into a project, creating the ThreeTopo app for climbers.<\/p>\n

He used a drone to shoot detailed photos of the 240-metre-tall climb and created a three-dimensional digital copy of that section of the rock face.<\/p>\n

The app examines the potential for new navigation and conveys the information to climbers. Pearman said it was also important to make it so climbers could use it one-handed when they consult it at safe points during the climb.<\/p>\n

As an example, a climber could ask the app for information on the best way forward while at one particular spot in the climb.<\/p>\n

The app could reply: \u201cYou\u2019ll want to start traversing left from the anchor. Once you hit the corner, start heading upwards until you reach a bolt. As soon as you get to that bolt, you need to traverse hard left, passing a pin to reach an anchor on the face.\u201d<\/p>\n

In the past, said Pearman, that kind of practical information came only in the form of cryptic, decades-old typewritten notes from other climbers.<\/p>\n

Miles Abesdris, who was in a group of experienced climbers asked to test the app, said it can take some of the scary unknowns out of trad climbing. <\/p>\n

Trad \u2014 or traditional climbing \u2014 involves the lead climber placing temporary, removable gear into the rock. They then clip in a rope to catch a fall. The second climber comes up behind and removes the devices, leaving nothing behind.<\/p>\n

\u201cThe first little while, (trad climbing) is somewhat horrifying, but you kind of become very comfortable there after a while,\u201d said Abesdris, 38.<\/p>\n

\u201cYour hands and feet are great, but you\u2019ve got to know where to go, right?<\/p>\n

\u201cThere\u2019s weaknesses in the rock. And you kind of follow the weaknesses and you kind of get a Spidey sense of where to go over the years \u2014 but sometimes you can be wrong.\u201d<\/p>\n

Pearman intends to make his app publicly available. He hopes other climbers will follow suit by detailing data on other popular North American routes from B.C. to Nevada, making the sport safer.<\/p>\n

\u201cI know a bunch of people who have had to be rescued by helicopter,\u201d he said.<\/p>\n

\u201cEveryone I know has gotten off route at some time.\u201d<\/p>\n
