The format is based on Keep a Changelog, and this project should adhere to Semantic Versioning.

[Unreleased]

Added

Changed

Fixed

  • Bug fix in createISO31662Grid when indexing natural earth data using iso_3166_2 column

Removed

[2.0.0] - 2021-10-01

Added

  • New default RUN script of RUN_2_geospatial_uncor
  • CreateTradespacePairingGeo is a helper function crete a tradespace of different combinations of input variables to createEncounters_2
  • trackTimetable2NEU converts tracks in timetable format to an array corresponding to time, north, east, and up coordinates
  • adjustTrack will adjust tracks based on output of samplespeedalt
  • estimateSpeedFromGeodetic is a helper function to estimate speed based on latitude and longitude
  • preallocAnchors, createISO31662Grid, and parseGeoTrajDirectory helper functions for step one
  • Persistent system environment variable of AEM_DIR_GEOPAIR established

Changed

  • Inputs to findPairs_1 changed to take advantage of calling preallocAnchors within findPairs_1. The step one RUN script was updated accordingly.
  • createEncounters_2 no longer reads in pre-generated files of tracks generated from the Bayesian encounter models; instead encounter model based tracks are generated dynamically using the new UncorEncounterModel class added to em-model-manned-bayes
  • createEncounters_2 will try multiple times to create an encounter with aircraft 1 and will now resample an encounter model to generate new Bayes tracks if needed. The previous version gave up too easily.
  • createEncounters_2 no longer organized loops by clusters and all clustering has been removed
  • createEncounters_2 loads FAA digital obstacle file using gridDOF from em-core
  • createEncounters_2 stores tracks as a timetable, a type of table that associates a time with each row. Helper functions like findconflict, samplespeedalt, and findCropIdx have been updated accordingly
  • createEncounters_2 outputs a table containing encounter metadata
  • createEncounters_2 and loadTrack will enforce the altitude range (altRange1_ft_agl, altRange2_ft_agl) when sampling the Bayes tracks. For Bayes tracks, altitude still cannot resampled using samplespeedalt and adjustTrack.
  • findconflict now considers HMD, VMD, and time criteria. It previously only assessed HMD.
  • findCropIdx also now checks for initial horizontal and vertical separation criteria
  • Renamed neu_to_wp_struct to to neu2Waypoints
  • Renamed startup to startup_pairing_geo
  • DEM handling updated based on improvements to msl2agl from em-core
  • Better random seed control
  • Improved plotting
  • Improved organization through the use of the code directory

Fixed

  • samplespeedalt handles rare case where the altitude span is less than 25 resulting in adjustSpan_ft_agl being empty
  • Fixed bug in findConflict when calculating hmd_ft and vmd_ft but tracks are not near each other
  • Various functions renamed using camelCase

Removed

  • croptracks, calcLegsTime, neu2wpstruct, updatewaypointstruct removed due to the addition of trackTimetable2NEU and updates to findconflict and findCropIdx
  • interpTime removed because time based interpolation is handled using the built-in functionality of the timetable type
  • RUN_2_sUAS_uncor and RUN_2_sUAS_unconv removed because they were deprecated by the more generalized RUN_2_geospatial_uncor script
  • RUN_2_sUAS_HAA removed due to change of sampling Bayesian networks at runtime. The Bayesian helicopter air ambulance model hasn't been tested yet with the EncounterModel objects in em-model-manned-bayes. This functionality maybe reintroduced in a future release.
