Boone County has worked hard to provide its citizens with technology to aid in the research of property records and geographic data. This is called a GIS (Geographical Information System).

Please be aware of the following:
The data presented are aggregated from a wide variety of sources. We have attempted to integrate these various data sources as well as possible. Each agency providing data may have their own internal standards for accuracy and timeliness, thus the GIS department cannot guarantee the degree to which the various data sources agree with each other. You may find that parcel lines (from the Auditor’s Office) may not line up exactly with aerial photography (Purchased from Pictometry) or census boundaries (derived from US Census maps) Each of these data sources must be considered on their own, for their own purposes, but comparisons among them may not be directly possible, and some manual interpretation may be necessary.

Data may also be created with specific scales in mind that may limit their accuracy. For example, topography data intended to be presented at a county-wide scale may have been simplified or created in a generalized manner such a manner that when zoomed to parcel detail you may not see small hills in comparison to the river valley.
There are also timing issues to work around, data sources may not be updated with the same frequency. Timing can even be an issue among county departments when the Auditor’s Office could have parcel data drawn in and Planning and Developmnet data may not be updated concurrently. Causing for recently modified parcels to have a discrepancy in the same data set.

GIS data sets are ongoing and constantly changing, they will never be completed. The GIS Department makes every attempt to keep the data as current and accurate as possible, but this data cannot be considered an authoritative source of data.
It is possible that there are some errors in the system. If you find one, please e-mail the GIS Coordinator and include the following information -
o Tax Description of the property in error (i.e. NW 1/4 of Section 10 of Marcy Township)
o PIN (Parcel Identification Number - 15 digit number starting with 08)
o Description of the error (i.e. My parcel is not shown as the correct size on the GIS maps)
o Your proposed idea for correction (i.e. My parcel is 120-feet wide not 60-feet wide)
Error reporting will only be accepted via e-mail due to the nature by which the GIS has been made available (on-line)
