etrsSurface-SpatialPolygonsDataFrame-ANY-missing-numeric-method: Etrs (source or Ancillary) surface creation

In etsakl/DasyMapR: Geographical ETRS-LAEA Grid Based Dasymetric Mapping

Description

Depending on each type of indicator or variable to be integrated within the reference grid, a different type of integration should be decided and tested. Besides the method finally chosen to integrate, it is important to highlight that indicator figures given by area unit, e.g. by square kilometre, should be converted considering that each cell has a total area of 1 km 2.

Usage

  ## S4 method for signature 'SpatialPolygonsDataFrame,ANY,missing,numeric'
etrsSurface(input.surface,
  over.method.type, surface.value.col, cell.size, ...)

Arguments

over.method.type	"PropCal" in proportional calculation the cell takes a calculated value depending on the values of the units falling inside and their share within the cell. This method seems very appropriate for countable variables
surface.value.col	the number of colum that keeps the relative density of a cell with land-cover some type
cell.size:	one of the resolutions of the grid that is 0.5m, 1m, 2.5m, 5m, 10m, 25m, 50m, 100m, 250m, 500m, 1Km, 2.5Km, 5Km, 10Km, 25Km, 50Km, 100Km

Value

EtrsSurface
