How does a vector layer work in raster?
Input vector layer with point, line or polygon geometries. Defines the attribute field from which the attributes for the pixels should be chosen. If activated writes the results into an existing raster layer. If the above option is not checked either the output size is in pixels (0) or the output resolution is in map units per pixel (1).
How are features converted to raster data in ArcGIS?
The first image shows polyline features as the input; the second image shows the output raster dataset. These images have been simplified to help show the differences. When you convert points, cells are usually given the value of the points found within each cell. Cells that do not contain a point are given the value of NoData.

How to set the output resolution in raster?
Defines the attribute field from which the attributes for the pixels should be chosen. If activated writes the results into an existing raster layer. If the above option is not checked either the output size is in pixels (0) or the output resolution is in map units per pixel (1). Sets the horizontal resolution of the output raster.
What is the error 6 in QGIS-rasterize?
ERROR 6: At least one of -3d, -burn or -a required. What am I missing? Identifies an attribute field on the features to be used for a burn-in value. The value will be burned into all output bands. A fixed value to burn into a band for all objects.
