Value proposition

Digitizes large-scale physical sites into highly accurate 3D models (cm-level precision) to automate progress tracking, safety monitoring, and earthwork volume calculations, reducing field survey costs and human error.

Products and solutions

["Meissa Platform: A web-based 3D drone data platform for construction site management.","Meissa Planet: Satellite imagery AI analysis solution for wide-area monitoring and defense.","Proprietary 3D Reconstruction Engine: Korea's first independent engine that converts 2D imagery into 3D spatial data.","InSAR Analysis Service: Satellite-based ground subsidence and structural displacement monitoring.","AI Analytics Suite: Automated features for earthwork measurement, blueprint-to-actual comparison, and safety hazard detection."]

Unique value

The only player in Korea with a proprietary 3D mapping engine and a hybrid 'Drone + Satellite' data pipeline, allowing for both high-resolution local site monitoring and wide-area global intelligence.

Target customer

Major construction and civil engineering firms (ConTech), national defense agencies, infrastructure management authorities, and mining operations.

Industries served

["Smart Construction (ConTech)","Aerospace & Defense","Civil Engineering & Infrastructure","Mining & Natural Resources","Public Safety & Disaster Management"]

Technology advantage

Eliminates dependency on expensive foreign 3D mapping software (e.g., Pix4D) through its own engine. Leverages 'Super Resolution' AI to enhance satellite image quality and InSAR technology for millimeter-level ground displacement monitoring.

How they differentiate

Meissa differentiates through its proprietary 3D reconstruction engine, eliminating dependency on foreign software royalties. It uniquely integrates both high-resolution drone data and wide-area satellite imagery (following its merger with Meissa Planet) to provide a comprehensive spatial AI analysis pipeline.
