Change Detection Services

Stay ahead of ever-changing property landscapes while significantly reducing field visits and increasing your tax revenue with Sidwell’s Change Detection services!

Benefits of Change Detection

✔ Locates structures that are not visible from the front of a property

✔ Saves time and money by identifying likely property changes before making field visits

✔ Increases valuations, tax revenue, and recurring tax revenue

✔ Aids in planning for county-wide assessment

✔ Finds property improvements not in tax rolls

✔ Finds changes in agricultural land use

Reveal changes in the use of agricultural land, particularly when woodland or pastureland is converted into cropland with Change Detection. That identified change will increase the assessed value of land and income for your jurisdiction!

With automated processing routines, Change Detection compares different years of imagery and identifies changes (including new construction, tear-downs, pools, decks, agricultural land use, etc.). Experienced technicians will then perform quality assurance tests.

Once the identified changes have been confirmed, Change Detection will maximize your staff resources by enabling efficient planning and prioritizing of field visits; thus, allowing focus on parcels with the most change to save you time, money, and energy.

Client Testimonial

. . . Sidwell Change Detection was a true eye opener. With limited staff and no county zoning, it’s impossible to keep up with all of the changes in Marion County. This service provided me with exactly which parcels I needed to visit and will save a tremendous amount of labor hours in the field.
