How to produce DOM image automatically or semi-automatically from satellite image

Jul 13, 2023

DOM production for a global map or rapid DOM production for a local area: By using appropriate filtering, registration, and fusion algorithms, multiple satellite or aerial images are combined to generate DOM images with consistent surface elevation information. You can choose between global DOM production or rapid DOM production for local regions.

DOM production based on the consistency of reference image: Using the elevation information of reference image, combined with registration and stitching technology, to generate DOM image with the consistency of reference image. This can be used to update or modify existing DOM data to ensure consistency and accuracy.

Rapid production of Regional DSM/DEM: Rapidly generate region-wide digital surface models (DSM) or digital terrain models (DEM) using multi-source satellite images, aerial images or liDAR data, combined with image processing and elevation extraction algorithms. These models provide surface elevation information and can be used for terrain analysis, 3D modeling and other applications.

Data processing services can automatically or semi-automatically produce DOM images according to customer needs and data availability, providing fast and accurate data processing and generation services.
