GeoThinneR 2.0.0
- We have improved the thinning algorithms by implementing two modifications of the kd-tree method: local kd-trees (
local_kd_tree) and restricted search (k_estimation).
- The round and hashing method (
round_hash) now is deprecated and has been removed from the package because of presenting lower accuracy than the other distance-based methods.
- The thinning method argument
method now includes the three main thinning strategies implemented in GeoThinneR for better understanding and usability. These are: "distance", "grid", and "precision".
- The
search_type argument has been included for distance-based thinning (method = "distance") to select between the search algorithms ("brute", "kd_tree", "local_kd_tree", and "k_estimation").
- The
long_col argument now is called lon_col for consistency with the lat_col argument.
- The default column names (
lon_col and `lat_col') have been changed from "decimalLongitude" and "decimalLatitude" to "lon" and "lat".
- The
n argument for the grid-based thinning (method = "grid") now lets you specify the number of points to retain per grid cell.
GeoThinneR 1.1.0 (2024-10-03)
- Removed non-CRAN dependency (
rtree) and associated functions related to R-Trees structure thinning method (r_tree_thinning()).
- Minor improvements to documentation.
