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
