How to convert from vector to raster?
To convert a vector to a raster format, QGIS provides the Rasterize tool. This tool converts a shapefile to a raster and applies the values in a specified attribute field to the cell values. To access the Rasterize tool, click on Rasterize (Vector to Raster) by navigating to Raster | Conversion.
How to raster in QGIS?

What is vector to raster?
Description. Converts vector geometries (points, lines and polygons) into a raster image. The algorithm is derived from the GDAL rasterize utility .
How to convert raster to vector in QGIS?
Click on Raster ‣ Conversion ‣ Polygonize (Raster to Vector). The tool dialog will appear. Change the field name (describing the values of the raster) to suitable. Save the shapefile under exercise_data/residential_development as all_terrain.shp.
How is a vector image converted to a raster image?
Converts vector geometries (points, lines and polygons) into a raster image. The algorithm is derived from the GDAL rasterize utility . 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.
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.
Why are raster and vector formats used in GIS?
Converting between raster and vector formats allows you to make use of both raster and vector data when solving a GIS problem, as well as using the various analysis methods unique to these two forms of geographic data. This increases the flexibility you have when considering data sources and processing methods for solving a GIS problem.
