LITAP 0.7.0

  • fix missing ddir in form_mapper()
  • clarify rule file usage and errors in facet_mapper()
  • Tweaks to align form_mapper flow decisions with the original LandMapR
  • Increase speed of QWETI calculations
  • Fix number of edge rows/cols removed
  • Add Topographical Summary outputs similar to those in Sheng et al. 2011 (summary_tables() etc. are now run by facet_mapper())
  • Fixed an discrepancy in wepp_mapper() which resulted in different channel mappings.
  • General tweaks and clean up of older usages

LITAP 0.6.0

  • Import x/y coords or create them if they don't exist
  • flow_mapper() now requires grid or infers from x/y value of input files
    • form_mapper() and wepp_mapper() now use grid inferred from x/y value of flow_mapper() output files
  • flow_mapper() now has upslope_m (upslope cells * grid^2)
  • flow_mapper() calculates UCED
  • facet_mapper() calculates buffer edges
  • Simplify output with 'debug' argument (if false, removes intermediate files)
  • Simplify output columns by removing intermediate ones
  • Remove option to 'end' a run prematurely (required due to simplified output)
  • Remove dbf output option because it truncates column names
  • Fix flow_mapper() inconsistencies
  • Add extra data output "topographical_derivatives" in facet_mapper
  • Initial work on all_points data output

LITAP 0.5.0

  • Load files forces to numeric (fixes problems where some imports in character)
  • Corrected slope_gc() directions (fixes #10)
  • Clarify output format and allow csv (fixes #13)
  • flow_mapper() has simplified output, similar to the other functions (fixes #12)
  • facet_mapper() has facets by number as well as by name, and ordered by crule (fixes #9)
  • form_mapper() values that are not on missing cells but can't be calculated due to local missingness, are assigned 0
  • Can load files even if dem in folder name (fixes #7)
  • Add rounding to match original LandMapR values where possible
  • Fix bug where grid parameter not passed on in form_mapper()

LITAP 0.4.1

  • Added slope_gc() to calculate slope gradients and curvature (added to dem_fill through flow_mapper())
  • Added merge_flow_form() to create a single dem file from flow_mapper() dem_fill and all form_mapper() outputs.

LITAP 0.4.0

  • Added facet_mapper() based on FacetMapR
  • Added wepp_mapper() based on WeppMapR
  • Internal changes to increase form_mapper() speed
  • Added ARULE deriving based on Li et al. 2011. Canadian Journal of Soil Science 91(2), 251-266.
  • Added both forms of calculating qweti, qarea, and lnqarea to form_mapper() (Originally values based on actual grid-cell area, now, qweti1, qarea1, lnqarea1 based on number of cells, and qweti2, qarea2, lnqarea2 based on grid-cell area).
  • Reduced number of output files
  • Updated reports

LITAP 0.3.1

  • Update to tidyr v1.0.0

LITAP 0.3.0

  • Added form_mapper() which mimics FormMapR
  • Renamed complete_run() to flow_mapper() to clarify what it refers to
  • Added new comparison reports
  • Fixed bugs related to incorrect vol2fl, parea and mm2fl
  • Added calculation of cumulative elevation differences to flow_mapper() which results in local_elev_diff (calculated after pit smoothing) and elev_diff (calculated after fill pits)

LITAP 0.2.1

  • Minor bug fixes relating to fixing large flat pits

LITAP 0.2.0

  • Major speed improvements, in some cases as much as 30x faster!
  • Added support for multiple input file types (?load_file for details)

LITAP 0.1.0

  • Initial build of LITAP including functions to mimic FlowMapR
  • Runs include log and report of results
  • Added a NEWS.md file to track changes to the package.
