Aerial Imagery

Stereo Mapping for Accurate Digital Feature Extraction
Stereo compilation or stereo mapping refers to the mapping or compilation of vector features from oriented stereo image pairs. This transformation process from raster data to vector information logically extends aerial triangulation results as it uses these 3D image outputs for collecting information about features such as roads, buildings and topography (such as elevation contours). More specifically, stereo compilation involves identifying and measuring the spatial features, after which they can be digitized for use as GIS vector layers. B2INGG provides accurate digital vector extraction as per industry standard formats, employing project specific procedures which deliver exceptional products at cost-effective prices and quick turnaround time.

Stereo compilation for Urban Mapping


Digital stereo photogrammetry mapping involves recognizing, measuring and extracting topography features using stereo image pairs. Today, stereo compilation is used widely for urban mapping applications. This is because cities have become the hotspots for economic and social activities and also to manage future growth, it’s necessary to map current growth of urban areas as accurately as possible. This explains the need for 3D mapping technologies for urban mapping applications.

Digital stereo photogrammetry compilation enables recognizing, measuring and extracting vector features such as terrain features, as well as built objects (individual buildings and smaller objects from street poles to manholes, fire hydrants and even smaller objects). All of this information is required for creating accurate 3D city models, which can be experienced in different ways and used for various purposes.

3D city models are digital replicas of cities and are used by city governments to plan, test and monitor their physical, economic and community structures. These models form the basis of digital twins, which enable cities to manage assets and public spaces in real-time leading to a better well-being and social environment for its citizens. In the coming years, digital twins will help cities realize changes to their social, economic and social structures as a result of the COVID-19 and changing climate.
