oneimpact provides tools for the assessment of cumulative impacts of multiple infrastructure and land use modifications in ecological studies.
The tools use R interface but the main calculations might be run in both R and GRASS GIS. The tools available so far are:
step_decay), linear decay (
tent_decay), exponential decay (
exp_decay), or Gaussian decay (
plot_zoi1d: plot ZOI in 1 dimensional space for multiple points infrastructure, using both the ZOI of the nearest feature and the cumulative ZOI metric.
calc_zoi_nearest: Calculate the zone of influence from the nearest infrastructure, according to multiple possible decay functions and zones of influence radii.
calc_zoi_cumulative: Calculate the cumulative zone of influence of multiple features, according to multiple possible decay functions and zones of influence radii.
calc_zoi: Calculate both the the ZOI of the nearest infrastructure and the cumulative ZOI, at multiple scales or zones of influence radii.
create_filter: Create filters or weight matrices for neighborhood analysis, according to different decay functions and parameterized using the zone of influence radius.
save_filter: Saves filters/weight matrices outside R for use within GRASS GIS modules.
grass_binarize: Binarize continuous or multi-class categorical rasters within GRASS GIS. Binary maps may be used as input for cumulative zone of influence and kernel density calculation.
grass_v2rast_count: Rasterize a vector files counting the number of features within each pixel of the output raster. Count rasters may be used as input for cumulative zone of influence and kernel density calculation.
set_points: simulate points in a landscape according to different rules and spatial patterns.
To install the development version of the
oneimpact R package, please use:
library(devtools) devtools::install_github("NINAnor/oneimpact", ref = "HEAD")
docker run --rm -p 8787:8787 -e PASSWORD=rstudio -v $PWD/myproject:/home/rstudio/myproject ghcr.io/ninanor/oneimpact:main
If you use Compose:
docker compose run rstudio
You can customize
docker-compose.yml based on your needs.
oneimpact functions are greatly based on neighborhood analyses made through the
terra package in R and on three GRASS GIS modules:
r.neighbors. The connection
between R and GRASS GIS is made through the
rgrass7 R package.
