% ssscoring(3) Version 1.8.1 | Speed Skydiving Scoring API documentation

Name

SSScoring - Speed Skydiving Scoring high level library in Python

Synopsis

pip install -U ssscoring

Have one or more FlySight speed run track files available (can be v1 or v2), set the source directory to the data lake containing them.

from ssscoring.calc import aggregateResults
from ssscoring.calc import processAllJumpFiles
from ssscoring.calc import roundedAggregateResults
from ssscoring.flysight import getAllSpeedJumpFilesFrom

DATA_LAKE = './resources' # can be anywhere
jumpResults = processAllJumpFiles(getAllSpeedJumpFilesFrom(DATA_LAKE))
print(roundedAggregateResults(aggregateResults(jumpResults)))

Output:

SSScoring processes all FlySight files (tagged as v1 or v2, depending on the device) and SkyTrax files. It aggregates and summarizes the results. Full API documentation is available at:

https://pr3d4t0r.github.io/SSScoring/ssscoring.html

Installation and requirements

• Python 3.9.9 or later
• pandas and NumPy

The requirements.txt file lists all the packages required for running SSScoring or using the API.

Quickstart

• The SSScoring interactive quickstart notebook for Jupyter/Lucyfer is the fastest way to learn how to use the library
• The ssscoring command line tool implements the same functionality as the interactive quickstart, can be used for scoring speed skydives from the command line with minimum installation - EXPERIMENTAL
• SSScoring browser tools - EXPERIMENTAL

Description

SSScoring provides analsysis tools for individual or bulk processing of FlySight GPS competition data gathered during speed skydiving training and competition. Scoring methodology adheres to International Skydiving Commission (ISC), International Speed Skydiving Association (ISSA), and United States Parachute Association (USPA) published competition and scoring rules. Though FlySight is the only Speed Measuring Device (SMD) accepted by all these organizations, SSScoring libraries and tools also operate with track data files produced by these devices:

• FlySight 1
• FlySight 2
• SkyTrax GPS and barometric device

SSScoring leverages data manipulation tools in the pandas and NumPy data analysis libraries. All the SSScoring code is written in pure Python, but the implementation leverages libraries that may require native code for GPU and AI chipset support like Nvidia and M-chipsets.

Features

• Pure Python
• Supports output from FlySight versions v1 and v2, and SkyTrax devices
• Automatic file version detection
• Bulk file processing via data lake scanning
• Automatic selection of FlySight-like files mixed among files of multiple types and from different applications and operating systems
• Individual file processing
• Automatic jump file validation according to competition rules
• Automatic skydiver exit detection
• Automatic jump scoring with robust error detection based on exit altitude, break off altitude, scoring window, and validation window
• Produces time series dataframes for the speed run, summary data in 5-second intervals, scoring window, speed skydiver track angle with respect to the ground, horizontal distance from exit, etc.
• Reports max speed, exit altitude, scoring window end, distance traveled from exit, and other data relevant to competitors during training
• Internal data representation includes SI and Imperial units; implementers may choose either one when working with the API

The latest SSScoring API is available on GitHub: https://pr3d4t0r.github.io/SSScoring/ssscoring.html

The SSScoring package can be installed into any Python environment version 3.9 or later. https://pypi.org/project/ssscoring

SSScoring also includes Jupyter notebooks for dataset exploratory analysis and for code troubleshooting. Unit test coverage is greater than 92%, limited only by Jupyter-specific components that can't be tested in a standalone environment.

What is a data lake?

A data lake is a files repository that stores data in its raw, unprocessed form. A speed skydiving data lake often has one or more of these types of files:

• FlySight versions 1 or 2 files
• SkyTrax files
• Video files (MP4 or MOV of whatever)
• PDFs of meet bulletins and related event information
• Miscellaneous other junk

SSScoring identifies FlySight and SkyTrax files regardless of what other file types are available in the data lake. SSScoring also identifies speed files from other types of tracks (e.g. wingsuit) based on the performance profile and scoring windows. Tell the SSScoring tools where to get all the track files, even if they are several levels deep in the directory structure, and SSScoring will find, validate, and score only the speed skydiving files regardless of what else is available in the data lake. The only limitation is available memory. SSScoring has been tested with as many as 467 speed files during a single run, representing all the training files for a competitive skydiver over 10 months.

Additional tools

• nospot shell script for disabling Spotlight scanning of FlySight file file systems
• umountFlySight Mac app and shell script for safe unmounting of a FlySight device from a Macintosh computer
