In 2010, the Village of Glenview started subscribing to a foreclosure
data-delivery service from Sullivan’s Law Directory. This information
is loaded into a GIS database, which is then used to generate reports
and reference maps. Village officials have used these weekly reports to
dispel myths about the community’s rate of foreclosures, monitor
properties proactively for code violations, and keep an eye out for any
patterns in criminal mischief.
Recently, GIS mapped this data in new ways to get different
perspectives on the impact of foreclosure rates. One project came from
Economic Development, which requested a map that symbolized foreclosures
according their primary usage. This map gave the Village planners a
snapshot of how foreclosures have impacted the local business community.
The map also provided a breakdown of percentages in each category,
showing that the proportional impact was low.
Another recent project was a spatial analysis of foreclosures for the
entire three-year period. By using an advanced tool called “kernel
density analysis,” GIS was able to simplify a large amount of
information by darkly shading areas where foreclosure rates have been
the highest. This analysis helped to pinpoint specific multi-unit
residences that have been particularly hard hit since 2010. These
ongoing projects highlight the power of tracking information with GIS.
Within minutes, the same information was analyzed from different
perspectives according to the end user’s needs.
Spatial patterns that are not apparent in a text list become obvious
when displayed on a map. While everyone hopes to see foreclosure rates
drop significantly in the near future, it’s great to know that the
Village has a versatile tool for proactively managing the ongoing
