Radon Potential
Overview


Figure 1: Radon potential map showing geocoded addresses and a single address from an inquiry.

Figure 1 shows the radon potential of the area from low to high.  Geocoded addresses are shown of the homes that conducted home radon tests.  A specific address is highlighted with a blue cross that indicates the location of a home owner who wanted to know the radon potential near their home.

Creating this map required:

  • Setting the geocoding properties

  • Performing a batch match

  • Performing an interactive rematch

  • Unioning layers to combine attribute data

  • Creating and updated fields of data

  • Classifying and displayed the results as a thematic map (see Figure 1)

  • Locating and displaying a single address

Other Uses of Address Geocoding

There are many other uses of address geocoding other than locating a house relative to radon risk.  Among them are emergency services (like 911), mapping services, repair services, and helping the U.S. Census.  Emergency services include directing fire, police, or an ambulance to a given location.  Mapping services include finding a person's address and getting directions from one address to another.  Repair services allow easy location of items needing repair by location relative to a given address.  Even the U.S. Census Bureau uses address geocoding to help count people!  When agents of the Census Bureau need to find homes that didn't return their questionnaires, address geocoding is used to help them locate a particular address.

Optional: Integrate New Customers

New Geocoded Customer Addresses

Figure 2 shows the new addresses added to the map, but they are on their own layer.  They have not yet been merged with the existing addresses (the green dots).

Merged Geocoded Customer Addresses


Figure 3: Yellow dots show all customers added to the map in a single, merged layer.

Figure 3 shows the new addresses merged with the existing customers to form a new layer (the yellow dots).
