About Us

SCALGO is developing the technology and products for a future where geographical data is continuously updated and available everywhere in high resolution



SCALGO was founded to bring cutting-edge massive terrain data-processing technology to market. SCALGO software builds on more than two decades of basic and applied research on I/O-efficient and geometric algorithms at Center for Massive Data Algorithms (MADALGO) at Aarhus University, Denmark, and at Duke University in the U.S., in collaboration with industry LIDAR and environmental GIS application experts. The SCALGO founders are world-leading researchers at these institutions. SCALGO maintains close ties to a number of research partners in order to continually improve and extend its software and service portfolio.
