In steffilazerte/LITAP: Landscape Integrated Terrain Analysis Package

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.
