3.4.4.8.1. Convertir vector a raster

Símbolo de la herramienta y nombre	Descripción
Select the vector	select a vector already loaded in QGIS
|recarga|	refresca la lista de capas
Use the value field of the vector	if checked, the selected field is used as attribute for the conversion; pixels of the output raster have the same values as the vector attribute
Use constant value	if checked, the polygons are converted to raster using the selected constant value
Select the reference raster	select a reference raster; pixels of the output raster have the same size and alignment as the reference raster
|recarga|	refresca la lista de capas
Tamaño de píxel	set the size of pixel of output raster
Minimum extent	if checked, the output raster has the minimum vector extent; otherwise, output extent is the same as the Select the reference raster
Select the type of conversion	select the type of conversion among: pixel_center: during the conversion, vector is compared to the reference raster; output raster pixels are attributed to a polygon if pixel center is within that polygon all_touched: during the conversion, vector is compared to the reference raster; output raster pixels are attributed to a polygon if pixel touches that polygon area_based: during the conversion, output raster pixels are attributed based on area proportion of polygons
Area precision	for area_based method, the higher the value, the higher is the precision in the calculation of area proportion (and the time required for calculation)
Usar el valor como Sin Datos	if checked, set a value for NoData pixels
