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
Understanding your project:
As you explain, you already have a class called Point child of GeoPoint.
what you want is the design of an algorithm: func analyzeTrack() -> Array {}
returning an array of tuples or something similar.
When you mention the criteria you mean those would be your possible scenarios that the function would return along the track itself?
And do you already have the app in place to the point to where this algorithm would receive the proper information?
Thanks,

Hi, I have been working as individual iOS developer, using swift. I'm new to freelancer but I have plenty experience offline.
I have read your description and totally understood the algorithm. It sounds interesting that I would like to have a try. Also, I'm open to full time freelance work for a long period.
Thanks.
