Sidwell’s Change Detection analysis process will identify likely changes to your jurisdiction’s landscape to support decision makers with a capabiltity to prioritize field visits. In addition to time and resource management, Change Detection analysis can also:
- Find property improvements not in tax roll
- Identify increased valuations
- Locate structures that are not visible from the front of a property
- Help in planning for county-wide reassessment
In Illinois, County Assessors rely on Township Assessors to assess properties. Sometimes in rural counties elected officials can’t be counted on to provide accurate assessments. Sidwell’s Change Detection analysis can close this gap, allowing County Assessors to pinpoint prioritized properties to visit.
Patty Brough, Marion County Illinois Supervisor of Assessments agrees, stating, “The new 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.”
Sidwell also offers in-house orthophotography services, which ties in well with Change Detection. The change analysis software uses sophisticated algorithms to analyze differences in the pixels of the orthophotos. This process is best accomplished when the aerial photography has been flown the same season, same time of day, and same pixel resolution. Sidwell will plan for a flight to coincide with an assessment quadrennial year, requiring less field work.
Sidwell’s Change Detection services offer multiple ways to improve assessment data utilizing existing imagery and new imagery. This is just another affordable service we can provide to our clients, enabling them to become more efficient and profitable.
