1. What is a benefit of raster data?

  • The resolution is not as clear as vector data and can make the data redundant
  • Can change the resolution to fit purpose of display
  • Mixed pixels are not as clear and hard to distinguish between
  • Redundancy of data by increasing the resolution which decrease topological error but increase volume of data
