What makes up a GIS?

Geospatial Data

  • Where?
  • What?
  • How?
  • When?

"Data Sandwich"

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

  • How is it being used in WTD?

GIS 

Don Cooke, early digital mapping pioneer about the explosion in mapping technology. His comment: “After 20 years, it’s nice to be an overnight sensation”.​​

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
