As was described in the August 2009 article, a Village of Riverside
master address database was created in the Geographic Information System
(GIS). This database was generated from several sources including
water billing, permits, fire inspections, and business licenses. Each
address follows the United States Postal standard format and is
represented geographically by a point at the location of the addressed
structure or property.
Another standard used in GIS is an address range. Address ranges are
represented by line features usually along the centerline of a roadway
and store the sequence of addresses on the left and right side of the
line (traditionally odd versus even addresses or vice versa). These
ranges are designed to match the addressed buildings as well as provide
for an estimate location of theoretical addresses between actual ones.
An address range can assist in address numbering in cases where
undeveloped land is subdivided and addresses need to be created. But
most often this resource is used for emergency support in which services
are dispatched to a location that is provided by an individual making
an emergency call. Emergency response could be delayed if dispatch
relied only on actual addresses because there can be miscommunication
between the call center personnel and those making the call. If the
address provided does not match an actual address the address range can
be referenced and provide the estimated location of that emergency to
ensure a timely response.
The standard that has been applied in Riverside is to break these
address lines at all intersections. This provides for yet another
locating option – to search for an intersection of two roadways rather
than an address. A block, intersection to intersection, ideally
consists of one hundred addresses but this type of address ranging
usually exists only in grid structured city centers. Therefore address
ranges are very useful for areas that do not follow a grid.
Locating by address, address range, or intersection introduces many
options by which to search for a place and each has their use or support
for one another. A user of this information simply needs to understand
how they benefit from each of these tools and apply them.
