polygonise_territories: Polygonize territories

In mottensmann/DBChecks: Checking Database

Description

Based on all nest coordinates for a given territory, a polygon area is created using 'Delaunay triangulation'. Geometries are simplified using the 'Dissolve option' in 'QGIS3'

Usage

polygonise_territories(
  nests = buzzard_db[["repro_fledge_db"]],
  root = "C:/OSGeo4W64",
  temp.dir = "Shapes/temp/",
  out = "Shapes/TerrPolygon2.shp"
)

Arguments

nests	data frame
root	root of QGIS installation. By default attempts to find it automatically
out	path
tempdir	temp directory

Details

Applied to each territory separately to avoid issues caused by overlapping geometric features. Resulting polygon are then merged within a single shape file layer. Note, the triangulation and polygonization only works if there are at least three coordinates available. Hence, if this criterion is not fullfilled dummy coordinates are added.
