Have you ever wondered how landscapes change over time? With SpatialScale’s topographic change detection, you can uncover these secrets with ease. Let's dive into how this fantastic tool can help you detect and analyze changes in elevation using LiDAR data.
Topographic change detection is like having a time machine for landscapes. You can see how construction, natural events, or other factors alter the terrain. This is invaluable for urban planning, environmental monitoring, and even archaeology. It helps you make informed decisions by providing clear insights into how areas evolve over time.
Imagine we’re looking at Jacksonville International Airport in Florida. Using the Discover module in SpatialScale, you draw an area of interest (AOI) around the airport and search for point cloud datasets. Let's use datasets from 2007 and 2018 available in the USGS repository.
Once the processing is done, you can open the result in the Explore module. Here, you'll see the change detection analysis. Red areas indicate objects present in 2007 but gone in 2018, while blue areas show new additions by 2018. This can reveal fascinating details, like where airplanes were during each LiDAR survey.
