prepPAcover: Prepare polygons for PAcover calculations

In darrennorris/cmartr: Functions for processing and analysing river turtle management

Description

Generates files for subsequent use. Optionally exports polygon as shapefile "pacover.shp".

Usage

prepPAcover(pPA = NA, pBasin = NA, pBasinSp = NA,
  make_shape = FALSE)

Arguments

pPA	Input file with protected area polygons.
pBasin	Input file with basin polygons.
pBasinSp	Input file with polygon covering basins in species range of occurance.
make_shape	Logical (TRUE/FALSE). Generate polygon shapefile of protected areas in 3 classes across basins in species range.

Details

To remove overlapping areas with different PA classifications. These are big areas and processing takes time: 4 - 5 hours on a laptop.

Value

Polygons of area covered by protected areas. Optionally exports polygon as shapefile "pacover.shp".

Examples

## Not run: 
# Load shapefiles needed
# These large files are not available via github package. 
# Download "shapes.zip" from :
# https://drive.google.com/open?id=1QQArA7pPLemUVQTKx7PxigsQXKpOG0YQ
# For the code below to work, 
# extract files in "shapes.zip" to cmartr/inst/shape .

B <- system.file("shape/amazon_orinoco.shp", package="cmartr")
pacover <- prepPAcover(pPA = PA, pBasin = B, pBasinSp = Bsp)
