1.7.4 (17th July 2020)

• Allow for the rasterisation of SpatialLines in create_lcp_density through the rasterize_as_points argument. If FALSE, SpatialLines are rasterised. If TRUE, SpatialLines converted to SpatialPoints and rasterised. See function documentation for more information.

1.7.3 (17th July 2020)

• Implemented type ‘autocorrelated’ and the calculation of probability intervals in add_dem_error

1.7.2 (7th July 2020)

• Implemented add_dem_error. See function documentation for more information and usage

1.6.2 (6th July 2020)

• Modified how lcp_density calculates which cells are covered by least cost paths. Instead of rasterising points (which can result in cells being missed), the least cost paths themselves are rasterised.
• Amended PDI_validation function to return area between lines

1.6.1 (5th July 2020)

• Implemented PDI_validation. See function documentation for more information and usage

1.5.1 (4th July 2020)

• Implemented crop_cs. See function documentation for more information and usage

1.4.1 (5th June 2020)

• Fixed create_stochastic_lcp when directional = FALSE. Now checks to ensure both Least Cost Paths are valid

1.4.0 (4th June 2020)

• Refactored code to enable greater flexibility
• Added 32 and 48 neighbour matrices based on Kovanen and Sarjakoski (2015) (see leastcostpath::neighbours_32 and leastcostpath::neighbours_48 for their layout)
• Implemented create_wide_lcp. Inspired by Shirabe (2016)
• Removed ‘all’ cost_function argument from create_slope_cs.

1.3.9 (1st June 2020)

• Implemented create_stochastic_lcp. Based on the method proposed by Pinto and Keitt (2009). See function documentation for reference

1.3.8 (1st June 2020)

• Least Cost Paths created using the create_FETE_lcps are automaticaly ordered low-to-high cost if the cost_distance argument is TRUE
• Least Cost Paths created using the create_CCP_lcps are automically ordered low-to-high cost if the cost_distance argument is TRUE
• Least Cost Paths created using the create_banded_lcps are automically ordered low-to-high cost if the cost_distance argument is TRUE

1.3.7 (15th May 2020)

• Fixed neighbour issue with cost_matrix

1.3.6 (13th May 2020)

• Implemented cost_matrix to be used with the create_lcp_network nb_matrix argument
• Fixed error in create_slope_cs when using 16 neighbours

1.3.5 (11th May 2020)

• Implemented create_barrier_cs

1.3.4 (4th May 2020)

• create_lcp returns SpatialLines rather than list
• Added cost_distance function argument to create_lcp

1.2.4 (29th April 2020)

• Fixed max_slope in create_slope_cs function
• Fixed create_traversal_cs to work when max_slope in create_slope_cs used

1.2.3 (28 April 2020)

• Added create_lcp_network vignette
• Fixed create_lcp_density issue where raster values of 1 would become 0 when rescale is TRUE
• Added Tobler’s offpath cost function
• Added irmischer-clarke male/female cost function
• Added irmischer-clarke offpath male/female cost function
• Added llobera-sluckin cost function
• Refactored create_slope_cs for easier scalability

1.2.2 (01 April 2020)

• Implemented create_lcp_network

1.2.1 (18 March 2020)

• Maximum slope traversable argument added to create_slope_cs function

1.2.0 (21 February 2020)

• Renamed create_lcp_network to create_FETE_lcps for consistency with academic literature
• Implemented create_CCP_lcps
• Implemented create_banded_lcps

1.1.0 (17 February 2020)

• Added create_cumulative_lcps function for the creation of cumulative least cost path rasters

1.0.0 (14 February 2020)

• Removed create_feature_attraction and replaced with create_feature_cs.
• Re-implemented create_lcp_network. Provides parallel and non-parallel functionality

0.1.6 (28 November 2019)

• Improved readability of create_traversal_slope function
• Addition of create_feature_attraction

0.1.5 (21 September 2019)

• Addition of create_cost_corridor function
• Removal of validate_lcp, create_openness, and create_lcp_network - these will be re-added at a later date.

Version 0.1.4 (19 March 2019)

• Split leastcostpath function into separate functions - allows for the building up of cost surfaces before computing least cost path
  • create_slope_cs
  • create_traversal_cs
  • create_openness_cs
  • Addition of openness cost surface creation

version 0.1.2 - Implemented cost when traversing across slope.

version 0.1.1 - Implemented choice of directionality

version 0.1.0 - First release to Github
