Before and After Imagery Plus Lidar Vs Aerial Examples

before-and-after-and-lidar-imagery-examples

How much does your site change year to year? 95West Aerial acquires repeat aerial imagery and Lidar scans to document those changes visually and quantitatively. We publish the results to a secure public or private website so stakeholders can explore the imagery, compare orthophotos to Lidar detail. Our team handles capture, processing, and web delivery so you get accurate, easy‑to‑see change detection.

Compare imagery side‑by‑side imagery over time or view the changes in aerial mapping technology like Lidar or infrared imagery. The following are examples completed for a variety of municipalities or private companies.

Track Development Progress:

95West flew over the Minneapolis/St. Paul International Airport to document the recent expansion of Terminal 2, the Hubert H. Humphry Terminal serving regional and smaller international airlines. Comparing the imagery from 2024 and 2025, you can clearly see the detailed changes before and after the construction and new development.

Emergency Response Documentation:

95West was contacted by Blue Earth County to document the damage from the Rapidan Dam failure. 95West combined aerial images with lidar data to create a three-dimensional model to document the damage of the Dam and the erosions from the Blue Earth River flooding in June 2024. Using the slider on the website, you can clearly see the change in landscape from before and after the extreme rain weather event.

Lidar and Photo Overlay:

95West pioneered simultaneous large-format imagery and high-density Lidar collection onboard its Cessna Caravan, fixed wing airplane. Our team can collect imagery and data, covering vast areas in one day on a single flight that would take sUASs (Small Unmanned Aerial Systems) or UAVs (unmanned aerial vehicles or drones) weeks of work and multiple flights. Simultaneous collection with side by side synchronized gyroscopic mounted sensors, provides greater calibration and data processing, to deliver your aerial mapping solutions quicker and with greater accuracy.

Transportation Documentation:

95West documented the CSAH 8 Roundabout development for Douglas County starting in 2019 by flying the intersection before the roundabout construction began. (%West flew the site multiple times durring construction. A final flyover after everything was completed was done to create an as-built model from Lidar and imagery combined to make a Digital Terrain Modeling, or DTM, of the intersection.

The key to collecting and showing these incremental changes and a wide variety of data is that 95West uses simultaneous collection of Lidar and high-resolution imagery. 95West’s large format sesnsors ensures ultra-wide area coverage and high point density, capturing more data in less time with fewer flight lines.
