Vector Data   &   Raster Data  

Vector Data - discrete entities: point, lines and plygons

Vector Data   &   Raster Data  

Raster Data - images consisting or regularly sized and spaced cells where every cell has a value

  • Treatment Plants - Points
  • Conveyance Line - Lines
  • Sewer Service Area - Polygon

Vector Data   

  • Digital Elevation Model (DEM)
  • One elevation value per cell

Raster Data
