NAME

v.area.weigh - Rasterize vector areas using weights

KEYWORDS

vector, interpolation, raster

SYNOPSIS

v.area.weigh
v.area.weigh --help
v.area.weigh vector=name [layer=string] [column=name] weight=name output=name [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog

Parameters:

vector=name [required]
Name of input vector map
Or data source for direct OGR access
layer=string
Layer number or name
Vector features can have category values in different layers. This number determines which layer to use. When used with direct OGR access this is the layer name.
Default: 1
column=name
Name of attribute column to use as area values (must be numeric)
weight=name [required]
Name of input raster with weights per cell
output=name [required]
Name for output raster map

Table of contents

DESCRIPTION

v.area.weigh rasterizes vector areas using known cell weights. In the output raster, the sum off all cells falling into a given area is identical to the area attribute value used to rasterize the area.

v.area.weigh can add spatial detail to larger areas, if more detailed information is available from other sources. For example, population counts are typically available for administrative areas such as provinces, counties or countries. At the same time, the location of urban areas might be known and can be used to refine spatial detail using v.area.weigh.
