Vector Data & Raster Data
Vector Data - discrete entities: point, lines and polygons
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

Companies are using maps not just as nice features but to drive revenue as core components of their offering. Maps are no longer just a good way to visualize content, they are core to competitive advantage.
Companies are thinking more creatively about how to combine location with outside content and internal business data to differentiate products
