Application for mountain skiers and snowboarders

This is small part of our application. Really we are looking for developer for full time freelance work for a long period. This is just entry task. Application for iOs, algorithm should be written on SWIFT The analyze track algorithm There is a track as an array (list) of points. Point this is class GeoPoint, which includes latitude, longitude and altitude. The track - record of movement of the skier (snowboarder) on ski resort during the all day. The algorithm should separate the following types of parts of the track • ascending with lift up • descending down • stop points (sitting in a restaurant, etc.) • Standing in line for the lift • Movement on the horizontal surface. The entire day should be separated to parts of the track. Algorithm should return an array (list) of pairs - the type of track parts and a part of the track itself as an array (list) of points. The criteria for the algorithm: • Raising the lift up - increase in height. • downhill skiing down - falling height • marking time (sitting in a restaurant, etc.) - all points within XX meters apart • Standing in line for the lift - very slow motion at a sufficiently short interval • Driving on a horizontal surface - other movements with a small difference in height between adjacent points • ascending with lift up – altitude is increased • descending down – altitude is decreased • stop points - all points within XX meters around • Standing in line for the lift - very slow motion at a sufficiently short distance • Movement on the horizontal surface - other movements with a small difference in height between nearby points
