Pictometry - The Aerial Oblique Imagery Company

Pictometry ChangeFindr® is a combined solution that features Pictometry Change Analysis® and an advanced change detection technology powered by HitachiSoft’s HouseDiff®.

Here’s how it works: HouseDiff identifies and chronicles changes to a property (such as new construction, additions and demolition). Then data is overlaid on imagery and displayed on either orthogonal or oblique imagery. Changes are highlighted for instant recognition. ChangeFindr then adds a second technology called Pictometry Change Analysis. This technology provides users with a rich side-by-side visual comparison of property changes over time. These features enable users to visually validate highlighted HouseDiff changes with ease and confidence.

Used primarily by professionals in assessment, GIS, real property tax, planning, and public safety, ChangeFindr is a recognized resource to assessors across the country who have been able to locate hundreds of thousands of dollars of taxable changes to properties in their jurisdictions – and all from the convenience of a computer desktop.

ChangeFindr Benefits include the ability to:

• Reduce field visits and allocate staff time resources more efficiently
• View properties with restricted of difficult access
• Capture previously undetected taxable property changes in a region
• Increase tax revenue by ensuring all changes are recorded, and
• Verify or correct existing information

Find Changes
HitachiSoft “HouseDiff – “HouseDiff” is an automatic change detection solution that creates GIS polygon “building outlines” for analysis of changes in size and shape. This technology can also compare existing building footprints to vector data created for the process of change detection. Changes are flagged for verification and analysis.

Validate Changes
Pictometry Change Validation is a stand-alone Pictometry solution that makes it possible for users to view side-by-side visual comparisons of properties overtime using aerial oblique or orthogonal imagery. When looking at any new image, this software automatically locates the corresponding image and displays it along side. When changing views or directions, Change Analysis automatically changes the view on the other to match. Pictometry Change Analysis overlays GIS data on top of imagery and can be used in a half-overlay mode to make visual analysis even easier. Change Analysis also enables users to measure the height, distance and area of changes for further analysis.

REVEAL, REVIEW, RECOUP

Pictometry is not an expense, rather, it’s an investment that can potentially yield returns year after year. ChangeFindr helps communities improve efficiencies and reduce expenses by.

• Reducing time and road expenses of preliminary site inspections
• Identifying changes restricted from view or when denied access to property
• Improving emergency and post-disaster response efforts by automating the
identification of change in hardest hit areas
• Increasing revenue from hidden tax valuations
