Abstract
The EC fp7 Integrating Project www.iqmulus.eu addresses the representation and processing of big geospatial data in the Cloud. One of the objectives is to address smooth ocean floor and provide LR-spline algorithms for accurate and compact approximation of hundreds of millions of data points acquired by LIDAR. The results provide a platform on which to build IGA solutions for geospatial problems, and a bridge from reverse engineering of human made shapes to IGA.
