Orthorectification is a process used to correct or transform satellite or aerial imagery to accurately represent terrain and features. Orthorectification results in true-to-scale images that can be used for various purposes, such as analyzing land use, ground measurements, monitoring changes and map creation. Intermap’s Orthorectification Service utilizes its high-resolution digital terrain models (DTMs) to correct distortions in imagery, providing customers with a reliable way to accurately visualize geospatial information from any source.
Leverage precise, globally available NEXTMap® elevation datasets with production-grade orthorectification processing infrastructure to transform raw satellite imagery into analysis-ready imagery. Service provides customers with accurate and consistent geometry throughout an image or image set, regardless of image source, with the option to incorporate imagery from multiple vendors and collection times.
Intermap’s Orthorectification Service supports optical and radar satellite sensors using a rational polynomial coefficient (RPC) sensor model
