A GIS model is a simplified representation of a complex problem that’s presented as a map.
In models that have variables, when these change, so too does the resulting GIS map.
In our GIS model of the compliance of onsite wastewater systems, three important variables that can change the map are...
- Soil Suitability for disposing of wastewater,
- the Wastewater Technology being used (low-tech or high tech), and
- the number of people living in the dwelling.
In this video you'll get to see how changing one of these variables can change a map.
