dynatopGIS 0.2.5

• fix bug in crosstab when computing input weights
• removed dependency on igraph

dynatopGIS 0.2.4

• Switch (with suboptimal code) to terra package over raster to fix handling of crs in meta data
• Removal of rgdal from suggests

dynatopGIS 0.2.3

• Calls to rgdal / rgeos replaced by calls to raster

dynatopGIS 0.2.2

• fixed bug in computation of channel area in the model
• fixed bug in reloading meta data when these was a classification
• added run-off attenuation parameters for hillslope HRU in create_model method

dynatopGIS 0.2.1

• Tidying up of vignettes and package imports for CRAN

dynatopGIS 0.2.0.9101

Breaking changes

• Previous classify method broken into two parts
  • classify to cut a layer into classes
  • combine_classes to combine classes using cantor pairing and burns
• Output of model altered to reflect changes in dynatop v0.2.0.9101

dynatopGIS 0.2.0.9030

Breaking changes

• Incorporated rainfall and pet weight into the model output

dynatopGIS 0.2.0.9030

Breaking changes

• New format for flow linkages in a separate table

other changes

• Added ability to compute weights for gridded inputs

dynatopGIS 0.2.0.9001

Breaking changes

• Altered model structure output to match change to surface zone celerity from time constant in dynatop v0.2.0.9001

dynatopGIS 0.2.0.9000

Breaking Changes

• Altered analysis of catchment to provide data for the bottom cross section of the HSU. This effects:
  • Derivation of flow directions and fractions for the HSU
  • Estimation of the width is now based on contour length

Other changes

• More efficient implementation of property computation using few passes of the data

dynatop 0.11

Other Changes

• Data sets for vignette split off into dynatopData package
• Under the hood changes to package build

dynatopGIS 0.1

Breaking Changes

• Code base reformulated in an Object orientated form using the R6 package. Except for change below algorithms as for v0.0.4
• Output format of model changed to reflect dynatop v0.1

New Features

• Reformulation allows for data and code to saved in a single object allowing full reproducibility
• Additional plotting functions
• Model creation algorithm changes to:
  • take sequence for most downslope band (rather then upslope)
  • Adjusts sequence rather then merging or dropping areas (still experimental) to ensure connectivity

dynatopGIS 0.0.4

Breaking Changes

• Uses a single multilayer raster file rather then a folder of raster files
• New algorithms will not produce identical results to v0.0.3

New Features

• New sink fill algorithm which should use fewer passes of the DEM
  • Fills from the sink with lowest possible value first.
  • Drops non-connected cells on the edge of the catchment
• Rewritten computation of HSU properties based on Quinn et al. 1995 and implemented in two passes of the DEM

dynatopGIS 0.0.3

Bug fixes

• Various minor bug

dynatopGIS 0.0.2

New features

• Added ability to continue a run of sink_fill by starting with previous filled dem

Bug fixes

• Model generation - missing average gradient property added and class of data frame columns altered
• Linking Rcpp function - alter NAMESPACE so should be included

Other changes

• Vignette know includes running of model and burning in a class

dynatopGIS 0.0.1

Other changes

• Removed vignette data from package to reduce size. Now on github
• Minor spelling and format changes to vignette

dynatopGIS 0.0.0.9000

Context

This package is the result of an almost complete rewrite of the dynatopmodel package formally on CRAN and the associated development code (not in the public domain).

This package contains the code for extracting the GIS summaries required for dynamic TOPMODEL and helpers for inserting default parameters. The package [dynatop]{https://waternumbers.github.io/dynatop/} contains the code for performing simulations.

New Features

• Change in approach to writing all intermediate files to - produce a record of analysis - allow for future developments with larger size GIS data
• Porting of sink_fill and atb calculations from original ‘topmodel’ CRAN package to Rcpp
• Improved method of determining river network intersection with DEM from shape files
• Changes to sink filling and atb calculations to recognise burnt in river network and correctly split flow by gradient
• Alterations to output mew style dynamic TOPMODEL object
• Vignettes added documenting function usage

Regressions of note

• No processing of distance histogram for river routing

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
