This is the future page for access to the Johnson County P.V.A. Geographic
Information System. This page will eventually link you to digital maps,
photographs and data on property ownership. We will eventually be able
to respond quickly and appropriately to requests for information by elected
officials, county agencies, the media and taxpayers. We will be able to
provide more efficient and easy public access to maps and parcel data.

What Is a GIS?
A geographic information system (GIS)
is a computer based tool for mapping which stores geographic information
in layers. GIS technology combines common database operations such as query
and statistical analysis with the visualization and geographic analysis
offered by maps. Essentially, a GIS gives the user the ability to associate
information with a feature on a map. GIS is a tool used by individuals
and organizations, schools, governments, and businesses seeking innovative
ways to solve their problems. Map making and geographic analysis are not
new, but a GIS performs these tasks better and faster than do the old manual
methods.
About GIS for State and Local Government
People in state and local government use
GIS every day to help them solve problems. Often the data collected and
used by one agency or department can be used by another. Following are
examples of how Gis can be used.
Tax Assessments
Property Valuation Administrators (PVA's)
are constantly challenged to locate and identify characteristics of new
property and to keep assessments in line with rapidly changing markets.
A GIS enables the PVA to locate and describe each parcel of land more efficiently.
This also ensures that tax bills are linked to the appropriate property.
Assess the Effects of Land Use Changes
A GIS can be used to find areas that will
be affected by changes in existing land use or zoning. The GIS can display
the current land use and zoning for parcels and provide the names and addresses
of the owners.
Track Cadastral Information
The GIS database can be used to store and
display parcel information such as legal descriptions, ownership, assessment,
and tax information. In addition the cadastral maps developed using the
GIS can be used as basemaps for water, electric, gas or other public utilities.
Assist Community Development
Census date displayed using a GIS show trends
or patterns that exist within a population.
Aid in Crime Prevention
Because a GIS can display patterns and trends in
data, law enforcement use GIS to show the location and frequency of different
crimes.
.
Manage Local Resources
Local governments use GIS to manage their
resources such as soils, geology, and current land cover. The GIS can generate
a statistical report containing information for each land use class by
county or for the entire state.
Aid in Redistricting
A GIS stores and displays census date according
to the needs of the user.
