Approximating LIDAR Ground Elevation Data by Higher-Order Tensor-Product B-Splines
DEM/DTM LIDAR Surface Modelling Reconstruction GIS
2015/12/8
We consider, in this paper, the problem of reconstructing the surface from LIDAR ground elevations. We reconstruct the surface by first rotating the LIDAR scan-lines so that they are parallel to the Y...
LOCALLY REFINED SPLINES REPRESENTATION FOR GEOSPATIAL BIG DATA
Big data smooth shape splines local refinement elevation model
2015/9/21
When viewed from distance, large parts of the topography of landmasses and the bathymetry of the sea and ocean floor can be regarded as a smooth background with local features. Consequently a digital ...
