Description

The HxGN Content Program, Hexagon’s aerial data program, offers the largest library of high-resolution multispectral aerial imagery and elevation data of the United States, Europe, and parts of Canada. The aerial data is orthorectified, accurate, and available at multiple resolutions. Data is captured on pre-defined schedules with flexible flight plans, enabling 100% artefact-free imagery with unparalleled consistency and accuracy.

Hexagon follows rigorous acquisition and processing standards to offer the highest positional accuracy for applications such as mapping, urban planning, asset management, public safety, utility mapping, insurance, app development, and many more. The exceptional data consistency over large areas makes it the ideal training data set for machine learning and AI algorithms. Flexible data use terms allow users to create derived products.
